It then sent the individual pieces over USB to four <a href="/Category:Teensy">teensy3 microcontrollers</a>, each which had eight <a href="http://www.adafruit.com/products/1376">WS281x 30 LED/m strips</a>. The tall panels had 5V 40A supplies, the smaller ones used 30A.</p> <h3 id="construction">Construction</h3> <p><img width="300" height="300" src="http://www.nycresistor.com/wp-content/uploads/2014/04/disorient-led-pyramid-assembly-party-300x300.jpg" class="attachment-medium alignleft wp-image-7250" alt="disorient led pyramid assembly party" /></p> <p>The project was a bi-coastal one -- the large panels were soldered and wired in California and much of the low level software was developed in New York. The boards were designed by Naim and available under an OSHW license. On site a crew of volunteers assembled the panels onto the pyramid structure built by the rest of the Disorient camp.</p> <p><img src="http://www.nycresistor.com/wp-content/uploads/2013/09/naim-pyramid-682x1024.jpg" alt="naim-pyramid" width="500" class="alignnone size-large wp-image-6368" /></p> <p>Operating in the harsh conditions of the Black Rock desert is difficult for electronics. We had lots of trouble with the powersupplies failing due to the heat and dust; next year perhaps we'll use more, but lower amperage, sealed DC supplies. The adhesive holding many strips to the pegboard failed. Several of the solder joints broke due to stress during mounting. Screw terminals rattled loose from the 25KW of sound system in the Disorient dome. There was late night soldering while hanging from the rafters of the pyramid. Despite all these problems, the panels and the sixteen thousand LEDs put on quite a show the entire week.</p> <p>A <a href="/Mini_Pyramid">Mini Pyramid</a> was also built for demos.
