It's much like tattoo, but you would have to shave every now and then.&lt;br /&gt;&lt;br /&gt;&lt;img src="http://www.interaction.rca.ac.uk/sites/default/files/imagecache/project_image/michiko.nitta/p3-1.jpg" /&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6278036977046705802-2104348349049299370?l=cheeriocheng.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cheeriocheng.blogspot.com/feeds/2104348349049299370/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://cheeriocheng.blogspot.com/2010/02/prosthesis.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/2104348349049299370'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/2104348349049299370'/><link rel='alternate' type='text/html' href='http://cheeriocheng.blogspot.com/2010/02/prosthesis.html' title='prosthesis'/><author><name>CheerioCheng</name><uri>http://www.blogger.com/profile/01090194670152121449</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_TpmlzqnIJ-k/S2e_W_PVPfI/AAAAAAAAC_A/TTGjpPo8_X8/s72-c/prosthesis.JPG' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6278036977046705802.post-2719733869178933652</id><published>2010-01-31T09:04:00.000-08:00</published><updated>2010-01-31T09:04:48.271-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='java'/><title type='text'>The system cannot find the file specified</title><content type='html'>two hours to figure this out??&lt;br /&gt;&lt;br /&gt;[Thanks to http://forums.java.net/jive/thread.jspa?threadID=36207&amp;amp;tstart=150] &lt;br /&gt;&lt;br /&gt;"highscore.txt" should be in your project's base directory, not in any of the directories that NetBeans has created for you.

In collaboration with artists Leslie Iwai and Jamie Burmeister, Min | Day designed the surface treatment for a 1,000-foot-long and 18-foot-high retaining wall that runs along a flood-control plain between a park and the University of Nebraska. The team developed a system of stainless-steel tiles that will reflect changes in the sky, floodwater levels, and activity in the park. Inspired by the work of mathematician Roger Penrose, Min | Day devised a system that uses tiles of only two shapes to create a pattern that has a five-fold rotational symmetry but never repeats.

Using the shift register to supply power like this is called &lt;i&gt;&lt;b&gt;sourcing current.&lt;/b&gt;&lt;/i&gt; Some shift registers can't source current, they can only do what is called &lt;b&gt;&lt;i&gt;sinking current.&lt;/i&gt;&lt;/b&gt;  If you have one of those it means you will have to flip the direction of the LEDs, putting the anodes directly to power and the cathodes (ground pins) to the shift register outputs. You should check the your specific datasheet if you aren't using a 595 series chip. Don't forget to add a 220-ohm resistor in series to protect the LEDs from being overloaded.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;My TPIC6C595 can only be used as drain... and the max source to drain current is 250mA.&lt;/b&gt;&lt;br /&gt;&lt;b&gt;The schema above wouldn't work, unless LED are reversed. &amp;nbsp;&lt;/b&gt; &lt;br /&gt;&lt;br /&gt;[http://www.arduino.cc/en/Tutorial/ShiftOut] &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;�3 states� refers to the fact that you can set the output pins as either high, low or �&lt;a class="urllink" href="http://en.wikipedia.org/wiki/High_impedance" rel="nofollow"&gt;high impedance&lt;/a&gt;.� Unlike the HIGH and LOW states, you can�t set pins to their high impedance state individually. You can only set the whole chip together. This is a pretty specialized thing to do -- Think of an LED array that might need to be controlled by completely different microcontrollers depending on a specific mode setting built into your project. Neither example takes advantage of this feature and you won�t usually need to worry about getting a chip that has it.&lt;br /&gt;[http://arduino.cc/en/Tutorial/ShiftOut] &lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;div&gt;&lt;/div&gt;&lt;div&gt;&lt;/div&gt;&lt;div&gt;&lt;/div&gt;&lt;div&gt;&lt;/div&gt;&lt;div&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6278036977046705802-3426217299052872030?l=cheeriocheng.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cheeriocheng.blogspot.com/feeds/3426217299052872030/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/in-this-case-you-should-connect-cathode.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/3426217299052872030'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/3426217299052872030'/><link rel='alternate' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/in-this-case-you-should-connect-cathode.html' title='Shift register'/><author><name>CheerioCheng</name><uri>http://www.blogger.com/profile/01090194670152121449</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6278036977046705802.post-1902527798540115422</id><published>2009-12-23T06:40:00.000-08:00</published><updated>2009-12-23T07:27:49.567-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Digi'/><title type='text'>Integrated circuit packaging</title><content type='html'>Digikey isn't as friendly as McMaster... so &lt;a href="http://en.wikipedia.org/wiki/List_of_electronics_package_dimensions"&gt;here &lt;/a&gt; wiki decodes the IC packaging dimentions.

Other options exist for non-thermo-plastic materials such as sewing, adhesives, heat activated tapes and mechanical means. However, for thermo-plastic materials, heat sealing is the most cost efficient method producing the best quality seam in the least amount of time. &lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1498"&gt;&lt;br /&gt;&lt;span&gt;For most applications, heat sealing processes include two critical components – application of heat under pressure followed by a cooling cycle or no heat under pressure. Depending on the method used, heat sealing can be used to seal 2 or more layers of material, similar and/or dissimilar materials, ie. Polyethylene to polyethylene, or polypropylene to polyester; and a wide range of material thicknesses (or weights). &lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1566"&gt;&lt;strong&gt;&lt;span&gt;&lt;/span&gt;&lt;/strong&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1567"&gt;&lt;span&gt;&lt;strong&gt;R.F. or High Frequency Heat Sealing&lt;/strong&gt;&lt;br /&gt;Uses high frequency energy to seal dielectric materials , i.e. vinyl. Typically high frequency sealing uses a bar of varying lengths and widths (1/4" to 2"). The dimension of the sealing bar creates the sealing pattern -- straight or curved. This process creates very nice looking seals, although high frequency sealing is relatively slow, expensive and only works with a limited range of materials, and does not work well with dissimilar materials.&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1523"&gt;&lt;br /&gt;&lt;span&gt;&lt;strong&gt;Ultrasonic Heat Sealing&lt;/strong&gt;&lt;br /&gt;Uses noise energy to seal thermo-plastic materials. Noise frequencies vary from approximately 15KHz (loud noise – larger sealing area) to 40 KHz (relatively quiet –small sealing area). Typical seam widths range from 1/4" to 1". Ultrasonic sealing can either be accomplished with a bar sealer or a rotary sealer. Not all materials can be ultrasonically sealed, although the material range is much greater than high frequency sealing.&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1524"&gt;&lt;br /&gt;&lt;span&gt;&lt;strong&gt;Wedge Welding&lt;/strong&gt;&lt;br /&gt;Uses a heated platen located between the layers to be welded. The heated platen or wedge moves between the layers with very little friction and therefore wedge welding is, perhaps, the fastest method for welding long lengths of material. Wedge welding can be used to produce straight and curved sealing patterns. Works very well with almost all thermo-plastic materials from plastics to synthetic textiles. Works better with thicker or heavier materials (over 20 mil per layer). Wedge welding used predominantly to weld vinyl or pvc coated textiles, high density materials (20-80 mil HDPE), synthetic textiles including polypropylene, polyester and nylon.

Takes the form of a bar sealer and is used predominantly to produce straight sealing patterns. Works best with thin materials ranging from under 5 to 10 mil to produce a seam width ranging from 1/8" to 1/2" on materials such as supported or unsupported vinyl, polyethylene, and many flexible materials. &lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1548"&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1549"&gt;&lt;span&gt;&lt;strong&gt;Pulse Sealing&lt;br /&gt;&lt;/strong&gt;Very similar to Impulse Sealing, however pulses the heated nichrome wire. The pulsing action emulates High Frequency and Ultrasonic heat sealing at significantly less cost. The method developed by &lt;/span&gt;&lt;a href="http://www.novaseal.com/"&gt;&lt;span&gt;Novaseal &lt;/span&gt;&lt;/a&gt;&lt;span&gt;is commonly used to make outdoor signs, billboards, posters and drapery systems, among other industrial uses where reduced sealing time is important. Works best with lightweight materials including polyethylene, vinyls and other thermoplastic materials ranging from 5 to 30 mil in thickness. Seam width ranges from 1/4" to 1", where 1" is the most popular.&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1553"&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1554"&gt;&lt;strong&gt;&lt;span&gt;Hot Air Sealing&lt;/span&gt;&lt;/strong&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1555"&gt;&lt;span&gt;Uses heated air directed between the two materials followed by a pressure means to heat seal materials. Sold in various forms from heat gun (looks like a hair dryer) to large industrial systems. Relatively inexpensive method, however prone to heating coil damage (down time) and heat sealing voids (sections of material that appear to be sealed but are not sealed). Two companies are leaders in sales of Hot Air sealing systems ... &lt;/span&gt;&lt;a href="http://www.leister.com/"&gt;&lt;span&gt;Leister &lt;/span&gt;&lt;/a&gt;&lt;span&gt;and &lt;/span&gt;&lt;a href="http://www.weldmaster.com/"&gt;&lt;span&gt;Miller Weldmaster&lt;/span&gt;&lt;/a&gt;&lt;span&gt;. Hot Air sealing can be used with virtually all thermoplastic materials.&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1563"&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1561"&gt;&lt;strong&gt;&lt;span&gt;Heated Platen Sealing&lt;/span&gt;&lt;/strong&gt;&lt;/div&gt;&lt;br /&gt;&lt;div id="ms__id1562"&gt;&lt;span&gt;Perhaps the oldest known form of heat sealing, this method uses one or two heated platens (also known as dies) to come into contact with one or both layers of thermoplastic materials. Most commonly used to heat seal curved or complex patterns. Drawback is that the heat is always on which may create safety and handling issues. &lt;/span&gt;&lt;/div&gt;&lt;/div&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6278036977046705802-8636226477988792427?l=cheeriocheng.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cheeriocheng.blogspot.com/feeds/8636226477988792427/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/heat-sealing-101.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/8636226477988792427'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/8636226477988792427'/><link rel='alternate' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/heat-sealing-101.html' title='Heat Sealing 101'/><author><name>CheerioCheng</name><uri>http://www.blogger.com/profile/01090194670152121449</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6278036977046705802.post-6120609569344282227</id><published>2009-12-20T17:17:00.000-08:00</published><updated>2009-12-20T17:24:37.584-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='inflatable'/><title type='text'>Ballons</title><content type='html'>&lt;table border="0" cellpadding="0" cellspacing="0" style="width: 358px;"&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td&gt;&lt;img height="243" src="http://www.thetech.org/exhibits/online/robotics/robotart/slideshows/images/paulos_2a.jpg" width="185" /&gt;&lt;br /&gt;&lt;/td&gt;                 &lt;td&gt;&lt;img height="1" src="http://www.thetech.org/exhibits/online/robotics/sharedimages/spacer.gif" width="10" /&gt;&lt;br /&gt;&lt;/td&gt;                 &lt;td&gt;&lt;img height="244" src="http://www.thetech.org/exhibits/online/robotics/robotart/slideshows/images/paulos_2b.jpg" width="163" /&gt;&lt;br /&gt;&lt;/td&gt;               &lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;&lt;a href="http://www.paulos.net/press/spiv/humjan1.html"&gt;&lt;b&gt;Artist with                Space Browsers&lt;/b&gt;&lt;/a&gt;&lt;br /&gt;Space                Browswers are simple airborne tele-robots.

Naming conventions explained.&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;How fast a battery can discharge is it's maximum current capacity. Current is generally rated in C's for the battery. &lt;b&gt;C is how long it takes to discharge the battery in fractions of an hour&lt;/b&gt;. For instance 1 C discharges the battery in 1/1 hours or 1 hour. 2 C discharges the battery in ½ or half an hour. All RC batteries are rated in milli Amp hours. If a battery is rated at 2000 mAh and you discharge it at 2000mA (or 2 amps, 1 amp = 1000mA) it will be completely discharged in one hour. The C rating of the battery is thus based on its capacity. A 2000mAh cell discharged a 2 amps is being discharged at 1C (2000mA x 1), a 2000mAh cell discharged at 6 amps is being discharged at 3C( 2000mA x 3).&lt;br /&gt;All batteries have limitations on how fast they can discharge. Because of this many LiPoly batteries are put in parallel to increase the current capacity of the battery pack. When 2 batteries are wired positive to positive and negative to negative they become like one battery with double the capacity. If you have 2 2000mAh cells and you wire them in parallel then the result is the same as 1 4000mAh cell. This 4000mAh cell has &lt;b&gt;the same C rating&lt;/b&gt; as the original 2000mAh cells did. Thus if the 2000mAh cells could discharge at a maximum of 5C, or 10 amps then the new 4000mAh cell can also discharge at 5C or (4000mA x 5) 20 amps. This method of battery pack building allows us to use LiPoly batteries at higher currents than single cells could produce. &lt;br /&gt;The naming convention that allows you to decipher &lt;b&gt;how many cells are in parallel and how many are in series is the XSXP method&lt;/b&gt;. The number in front of the S represents the number of series cells in the pack so 3S means it's a 3 cell pack. The number in front of P means the number of cells in parallel. So a 3S4P pack of 2100mAh cells has a total of 12 cells inside. It will have the voltage of any other 3S pack since the number of cells in series determines the voltage. It will have the current handling of 4 times the maximum C rating of the 12 individual cells. So say our 3S4P pack had a maximum discharge of 6C. That means that it has a nominal voltage of 10.8 volts (3x3.6) and a maximum discharge rate of 50.4 amps (2100mAh x 6Cx4P ). &lt;br /&gt;[http://www.rcgroups.com/forums/showthread.php?t=209187]&lt;br /&gt;&lt;br /&gt;&lt;div class="post-content"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="post-content"&gt;&lt;span style="font-size: large;"&gt;&lt;b&gt;Lifetime &lt;/b&gt;&lt;/span&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="post-content"&gt;Expect to get at least 300 cycles during the lifespan of the batteries, if you take care when charging/discharging. &lt;br /&gt;&lt;/div&gt;&lt;div class="post-content"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="post-content"&gt;&lt;b style="font-weight: normal;"&gt;Do not&lt;/b&gt;&lt;b&gt; &lt;/b&gt;store lipos at 100 percent charge, and you should&lt;b&gt; &lt;b&gt;not&lt;/b&gt; &lt;/b&gt;store them at near minimum voltage. Either of these situations will result in the battery internally “rusting away”, and will decrease it’s capacity over time. The best way to store a lipo is at about a &lt;b&gt;50% charge, in a cool, dry location.&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;No charger will undo the permanent chemical reactions which take place within an over discharged cell.&lt;br /&gt;&lt;br /&gt;Lithium batteries like heat, but not too much. In the winter time, try to keep your batteries from the cold as much as possible. Leave them in the car while your flying, or keep them in your cargo pants... etc. At the same time don't let them heat up too much. Try to keep your batteries from reaching 160F after use. This will prolong the life of the cells. A good way to measure temperature is a handheld IR meter, they can be found for around $50.00 at most hobby shops. &lt;br /&gt;&lt;br /&gt;[http://www.rctoys.com/pr/category/rc-information/lithium-polymer-battery-info/] &lt;br /&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="post-content"&gt;&lt;span style="font-size: large;"&gt;&lt;b&gt;Safety&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;&lt;ol&gt;&lt;li&gt;&lt;b&gt;&lt;a href="http://www.rctoys.com/rc-toys-and-parts/DF-LIPOSACK/RC-PARTS-CHARGERS-BALANCERS-POWER.html" target="_self"&gt;&lt;img align="right" alt="" class="alignright" height="60" src="http://www.rctoys.com/images/products/thumbnails/DF-LIPOSACK_1.jpg" title="Use a Lipo Sack to Keep Safe" width="80" /&gt;&lt;/a&gt;Store lithium polymer batteries in a flame proof LipoSack while charging. &lt;/b&gt;- &lt;/li&gt;&lt;li&gt;&lt;b&gt;Read the manual&lt;/b&gt;&amp;nbsp;&lt;b&gt;&amp;nbsp;&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;&lt;b&gt;&amp;nbsp;&lt;/b&gt;Don’t charge batteries unsupervised&lt;/b&gt;. &lt;/li&gt;&lt;li&gt;&lt;b&gt;Use the right battery charger &lt;br /&gt;&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Keep a fire extinguisher, or bucket of sand near the charging area&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Don’t charge lithium polymer batteries near flammable substances&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Check lithium polymer batteries for swelling prior to charging and each use – &lt;/b&gt;A puffed battery is unstable, and can be in danger of exploding. If you see a puffed battery, immediately disconnect it from the charger or aircraft and put it in a bucket of water. Dissolve a few tablespoons of salt in the water to aid conductivity, and leave the battery in the bucked for about 4 days. The salt water depletes any power remaining in the battery by creating a short, and it can’t catch fire while underwater. After the four days are up, take the battery out and cut off the connectors (which may come in handy for other projects). You can then dispose of the battery in the trash. The battery no longer contains toxic metals, won’t harm the environment, and by using the salt water you’ve guaranteed that it won’t catch fire. This should be done &lt;b&gt;as soon as you see a puffed battery.&lt;/b&gt; You can’t salvage a puffed battery, the best you can do is to dispose of it safely.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Never charge a lithium polymer battery in a model &lt;br /&gt;&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Make sure the charging leads are connected properly –&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Don’t overcharge batteries – &lt;/b&gt;By their very chemistry, lithium polymer batteries cannot be discharged to a potential of less than 3 volts without damage. For the same reason, don’t charge them to over 4.2 volts. This means that you have to land your rc aircraft &lt;b&gt;before&lt;/b&gt; the motors stop turning. Some aircraft come equipped with a voltage cut-off, others do not. If you don’t have a voltage cut-off, then land as soon as you sense the propeller or rotors slowing down.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Balance lipo batteries – &lt;/b&gt;Lithium polymer batteries have balance connectors, designed to make sure that each cell in the pack has the same charge. If this isn’t the case, some cells can become overcharged and explode.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Never let the battery leads touch &lt;br /&gt;&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Don’t ever store / charge lithium polymer batteries in your ca&lt;/b&gt;&lt;/li&gt;&lt;li&gt;&lt;b&gt;In the event of a crash, remove the battery and supervise it for at least 4 hours &lt;br /&gt;&lt;/b&gt;&lt;/li&gt;&lt;/ol&gt;[http://www.rctoys.com/pr/category/rc-information/lithium-polymer-battery-info/] &lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6278036977046705802-8433396014622848416?l=cheeriocheng.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cheeriocheng.blogspot.com/feeds/8433396014622848416/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/lipo-batteries.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/8433396014622848416'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/8433396014622848416'/><link rel='alternate' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/lipo-batteries.html' title='LiPo Batteries'/><author><name>CheerioCheng</name><uri>http://www.blogger.com/profile/01090194670152121449</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6278036977046705802.post-6091727368979408028</id><published>2009-12-18T14:44:00.000-08:00</published><updated>2009-12-20T11:15:50.178-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='EnS'/><title type='text'>Brushless DC electric motor</title><content type='html'>&lt;div class="separator" style="clear: both; text-align: center;"&gt;&lt;a href="http://upload.wikimedia.org/wikipedia/en/thumb/3/3f/Brushless-Motor-DUM60.jpg/241px-Brushless-Motor-DUM60.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"&gt;&lt;img border="0" src="http://upload.wikimedia.org/wikipedia/en/thumb/3/3f/Brushless-Motor-DUM60.jpg/241px-Brushless-Motor-DUM60.jpg" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/div&gt;&lt;span style="font-size: small;"&gt;A brushless DC motor (BLDC) is a synchronous electric motor which is powered by direct-current electricity (DC) and which has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes.

A 980Kv motor powered by an 11.1V battery would spin at 980 x 11.1 = 10878 RPM with no load.&lt;br /&gt;&lt;br /&gt;The &lt;b&gt;current rating &lt;/b&gt;specifies the maximum continuous and/or burst current that the motor is able to handle.

An outrunner motor has stationary coils at the center, and the rotating magnet on the outside. Outrunner motors generally have lower Kv ratings, meaning they run at a lower speed, but with more torque, which would allow you to direct drive larger props without needing a gearbox. Most RC cars and boats would require an inrunner brushless motor.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;[http://www.rctoys.com/rc-products-catalog/RC-PARTS-BRUSHLESS-MOTORS.html]&lt;br /&gt;&lt;h1 class="firstHeading" id="firstHeading" style="font-weight: normal;"&gt;&lt;span style="font-size: small;"&gt;&lt;/span&gt; &lt;/h1&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6278036977046705802-6091727368979408028?l=cheeriocheng.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cheeriocheng.blogspot.com/feeds/6091727368979408028/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/brushless-dc-electric-motor.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/6091727368979408028'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/6091727368979408028'/><link rel='alternate' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/brushless-dc-electric-motor.html' title='Brushless DC electric motor'/><author><name>CheerioCheng</name><uri>http://www.blogger.com/profile/01090194670152121449</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6278036977046705802.post-904433797453736096</id><published>2009-12-16T12:27:00.000-08:00</published><updated>2009-12-20T10:50:39.850-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='architecture'/><category scheme='http://www.blogger.com/atom/ns#' term='EnS'/><title type='text'>voronoi diagram</title><content type='html'>&lt;div class="separator" style="clear: both; text-align: center;"&gt;&lt;a href="http://people.sc.fsu.edu/%7Eburkardt/f_src/sxyz_voronoi/gen_00100.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"&gt;&lt;img border="0" height="320" src="http://people.sc.fsu.edu/%7Eburkardt/f_src/sxyz_voronoi/gen_00100.png" width="320" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;named after Russian mathematician &lt;a href="http://en.wikipedia.org/wiki/Georgy_Voronoy" title="Georgy Voronoy"&gt;Georgy Fedoseevich Voronoi&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&amp;nbsp; The segments of the Voronoi diagram are all the points in the plane that are equidistant to the two nearest sites.&lt;br /&gt;&lt;br /&gt;Voronoi diagrams are used in&lt;br /&gt;&lt;ul&gt;&lt;li&gt;&amp;nbsp;&lt;/li&gt;&lt;li&gt;find the largest empty circle amongst a set of points, and in an enclosing polygon; e.g. to build a new supermarket as far as possible from all the existing ones, lying in a certain city.&lt;/li&gt;&lt;li&gt;computer graphics to procedurally generate some kinds of organic looking textures. &lt;br /&gt;&lt;/li&gt;&lt;/ul&gt;[http://en.wikipedia.org/wiki/Voronoi_diagram] &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Beijing National Aquatics Center by &lt;a href="http://www.vector-foiltec.com/"&gt;Vector Foiltec&lt;/a&gt;&lt;b&gt;&lt;/b&gt;&lt;br /&gt;&lt;div class="separator" style="clear: both; text-align: center;"&gt;&lt;a href="http://www.vector-foiltec.com/images/backgrounds/technical.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"&gt;&lt;img border="0" height="249" src="http://www.vector-foiltec.com/images/backgrounds/technical.jpg" width="320" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;b&gt;The Texlon® cladding system &lt;/b&gt;The cushions are manufactured from between two and five layers of the modified copolymer Ethylene Tetra Fluoro Ethylene (ETFE).

The group opened offices in Düsseldorf (1970) and NYC (1971), so quickly became international. Specializing in ‘disposable architecture’, pneumatic structures, air-mattresses, and life-support systems, its projects (often featuring plastics) have included Balloon for Two (1967), the external shell around the Haus Lange Museum, Krefeld (1971), and the Oasis 5 in Kassel (1972). Among unrealized projects that have received attention are the Pneumacosm pneumatic-cell expansion of NYC (1967) and an artificial cloud with a huge ladder for access (the Big Piano—1972). &lt;a href="http://www.encyclopedia.com/doc/1O1-Archigram.html"&gt;Cook&lt;/a&gt; has identified Haus-Rucker-Co as contributing to &lt;a href="http://www.encyclopedia.com/doc/1O1-Experimentalarchitecture.html"&gt;Experimental architecture&lt;/a&gt;.&lt;br /&gt;&lt;/div&gt;&lt;div class="separator" style="clear: both; text-align: left;"&gt;&lt;br /&gt;&lt;/div&gt;&lt;a href="http://www.zamp-kelp.com/pics/projects/00_hrc/1973/gr_Lunge%20/01_gr.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"&gt;&lt;img border="0" src="http://www.zamp-kelp.com/pics/projects/00_hrc/1973/gr_Lunge%20/01_gr.jpg" /&gt;&lt;/a&gt;&amp;nbsp;&lt;span id="result_box"&gt;&lt;span style="background-color: white;" title="Anläßlich einer Ausstellung wurde im Kuppelsaal der Kunsthalle Hamburg die &amp;lt;Grüne Lunge&amp;gt; installiert."&gt;On the occasion of an exhibition was in the domed hall of the Kunsthalle in Hamburg installed &lt;grüne lunge=""&gt;. &lt;/grüne&gt;&lt;/span&gt;&lt;span style="background-color: #ebeff9;" title="In der Mitte eines quadratischen Beckens von 6 m Seitenlänge aus weißem Kunststoffgewebe stand ein Stahlrohrturm, ganz oben ein verglaster Kubus, in dem sich zwei Tröge mit natürlichem Grünzeug befanden."&gt;In the middle of a square pool of 6 m side length of white plastic tissue a steel tower stood at the top of a glass-cube, in which there were two barrels with natural greenery. &lt;/span&gt;&lt;span style="background-color: white;" title="An den Stirnseiten des Kubus waren zwei halbkreisförmige, in Kammern unterteilte Luftkissen aus durchsichtiger Folie -die Lungenflügel- angebracht, die über wechselweise gesteuerte Gebläse Luft aus dem Grünkubus ein- und ausatmeten."&gt;On the front sides of the cube were two attached semi-circular, divided into chambers made of transparent foil cushion the lungs, which over alternately controlled blast from the green cube and breathes. &lt;/span&gt;&lt;span style="background-color: white;" title="Wie die Flügel einer menschlichen Lunge, hoben und senkten sie sich dabei und stießen die Luft gefiltert und aromatisiert mit künstlichen Zusätzen in ein Schlauchsystem, das quer durch das Gebäude zu einer Abnehmerstelle auf dem Platz vor der Kunsthalle führte."&gt;Like the wing of a human lung, lifted and pushed by them and they lowered the air is filtered and flavored with artificial additives in a tube system, which led right through the building to a customer location on the square in front of the Kunsthalle.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;&lt;span id="result_box"&gt;&lt;span style="background-color: white;" title="Wie die Flügel einer menschlichen Lunge, hoben und senkten sie sich dabei und stießen die Luft gefiltert und aromatisiert mit künstlichen Zusätzen in ein Schlauchsystem, das quer durch das Gebäude zu einer Abnehmerstelle auf dem Platz vor der Kunsthalle führte."&gt;[google translate from &lt;a href="http://www.blogger.com/%20http://www.zamp-kelp.com/galerie/themes.html/hrc/1973/gr_Lunge%20/gr_Lunge.html"&gt;here &lt;/a&gt;] &lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6278036977046705802-5816714015493520392?l=cheeriocheng.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cheeriocheng.blogspot.com/feeds/5816714015493520392/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/haus-rucker-co.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/5816714015493520392'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6278036977046705802/posts/default/5816714015493520392'/><link rel='alternate' type='text/html' href='http://cheeriocheng.blogspot.com/2009/12/haus-rucker-co.html' title='HAUS-RUCKER-CO.'/><author><name>CheerioCheng</name><uri>http://www.blogger.com/profile/01090194670152121449</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry></feed>
