An earlier drilling test can be seen to the right of the LED's. As it stands I am not sure I am a fan of our current plan, each LED cluster will require 4 holes, which equates to 56 * 4 = 224 holes, each one of which needs to be pretty precisely placed to not over bend the LED leads and not to drill them so close that the holes merge.

A cool LED light installation in the lobby of the Telus Tower in Toronto, Ontario, Canada. The LEDs cycle through the visible colour spectrum in a coordinated manner which was pretty cool to watch.
Solar LED Lantern Distribution, Bhako Village May8, 2012
Tharparkar District, Province of Sindh, Pakistan
Pervaiz Lodhie “Pehli Kiran” socio-economic poverty alleviation program for rural Pakistan’s poorest marginalized communities. 500 LED Lanterns
Manufactured and donated by Shaantech KEPZ Karachi gifted to 500 families of Bhako, Kharoro and Vekasar Villages. These villages are only couple of miles from the India border, Nagarparkar area of Thar desert. Majority of people are Hindus. No roads into these villages. We had to use 4-Wheel Drive UNDP vehicles.
Trip and distribution facilitated and supported by:
Masood Lohar, UNDP Green Environment Facility (GEF) Small Grants Programme
Abbas Khoso, Integrated Rural Awareness and Development Organisation (IRADO)
Present on the trip:
Pervaiz Lodhie, LEDtronics, USA
Shahid Siddiqui, Shaan Technologies (Pvt) Ltd, Karachi, Pakistan
Simple demo of the LED driver, and the look of two different types of diffusers.
Also shows the results of my first real attempt at SMD skillet reflow. (woot!)
(wish I could get the lighting/exposure to both be long enough to hide the scanning but short enough so the light from the LEDs doesn't blow out the image)
Here's a detail shot of the clip on LED's. They've got a ball and socket adjustable mount. This will come in handy later.
Haciendo limpieza en la caja de componentes electrónicos, voy comprobando los led que no "lucen" con el polímetro y también para ver si son infrarrojos (IR).
LED strip lights, ribbons or tapes are one of the most popular LED products available on the market.
Here's the circuit for the Black Box Lightshow. I'm pretty sure it's right. And now, an explanation:
The LED array is shown here as individual diodes, though I used six 5x7 LED arrays, each one is 2" tall. They are arranged as 14 rows and 15 columns. The left channel is 8 columns and the right channel is 7 columns. The extra column from the left channel is the center column and gives nice symmetry. Not shown here is that on the right channel, the first column (pin 1) is not used so that the other columns are equal.
The LM3914 is a Dot/Bar Display Driver. It does all the heavy lifting of converting the audio signal into a series of bars - these are typically used as digital meters. The potentiometer sets the sensitivity of the display. Since the rows are multiplexed (see below), each column is only driving one LED at a time. I only show the left channel here, the right channel is identical, and they share the level setting potentiometer.
The right portion of the diagram is a 555 clock, a 7493 4-bit counter and a 74154 4-to-16 line decoder/demultiplexer. This is the "sweep" part of the display that cycles through each row of LEDs. The potentiometer at the top controls the sweep speed. The net result is that the 74154 is cycling through the pins/rows, grounding each in succession. Note that I only have 14 rows, but it is counting to 16 each time. No big deal, it doesn't affect the perceived output at all.
The N2907 transistors are there to provide enough power for all the LEDs. Potentially, all 15 LEDs in a row can be lit up at once, so the transistors make sure there is enough juice.
Unfortunately, I lost the original plans during a garage cleaning after I built the electronics (the box took another few months before I got around to it). I opened it up and reverse engineered my own work. I won't guarantee it, but it sure looks right to me. The one weird thing I found is that I don't have power going to pin 8 of the 555 (as shown here), but it works fine - go figure. Also, I'm not 100% sure I got the polarity of the LEDs right, sorry about that. I would recommend testing that out first.
Please post if you build this and let me know! Also, happy to answer questions along the way.

It is hardly seen on this photo though, but instead of normal light tubes, this bus is equipped with a row of LED's hidden in the tub that act as normal tubes. This seems to be done to make the lightinig energy effictent.

I first saw these "thignamajigs" during the Milenyo brownout streak at my aunt's apartment. Aside form being infinitely better than candles, at 50 bucks a piece, they're the best "instant producy photography" light sources that my money could buy. LED's rock!!! Anybody know where I can get these cheaper? Or in bulk? I'd sure as hell like to get me a whole box of!!!
At the after-party from the 2013 Maker Faire. Macetech showing off their RGB LED shades (just after I bought a set of the monochrome ones). DAAAAMMMN YOUUUU! (not really, I'll buy those too!)

The IRiS LED Star Panel is a fantastic new product that gives the impression of stars disappearing out of view. It utilises bright LED’s to create this unusual, dazzling effect. The unit can be controlled using any IRiS Talker making it very versatile. The IRiS LED Star Panel is lightweight so very portable and can be used for colour recognition, cause and effect, switching skills and others, depending on the IRiS Talker used.
