    I use a heavy duty paper guillotine that I bought for $5 from a yard sale. It's good for 1.6mm.

    Update for users that have requested controller boards.
     

    They've all be soldered up, and they all program fine.
     
    I just want to make sure that the accelerometers work, and that these boards can actually drive LEDs
     
    I hit a wall with my demo program, and the i2c code I was using, it didn't support repeated start, which this accelerometer needs to read from any registers other than accelerometer data.
    I only made progress when I started using an ez430-rf2500 board, hooked upto a sensor board, (both MSPs have UCB0 for i2c), using my scope I finally got some code to work.
     
    Unfortunately as I'm a full time uni student, I might not have enough time (during business hours) to post the boards off tomorrow. But it will happen later this week.
     
    Edit:
    I think others mentioned they've measured current, but I couldn't find their results.
    I don't have any high powered +5v sources (except maybe some PC ATX power supplies hmmmm)
     
    So 3 LEDs max brightness (r,g,b ), measured 0.28A @ 5.0v
    so, following that logic, all 120LEDs would come to 0.28 * (120/3) = 11.2A, which is about 56W
     
    If you wanted to run them at that brightness they do start to generate heat. But it is a possibility

    I've been working on the code for the control board. Here is a quick demo.
     


     
     
    I've ordered a few more parts (accelerometer, regulator, levelshifter) which my board is running without currently.
     
    Here is a BOM (not including LEDs)
     
    Accel (MMA 8453) $1.31 level converter       $0.26 resistor/caps    14x $0.003 regulator         $0.60 32.768kHz crystal  $0.726 MSP430g2553  $2.73 Total: $5.40
     
    Since the BOM is quite low, I would have no issue populating some of these board for other members, (I would make this a donation to cover BOM+time.) but how about a flat $10USD
    If you'd like to DIY, I can ship the bare PCBs for free to members of the group-buy.
     
    Also, if you'd like a controller, but don't have any LEDs left, I have a few left.

    Looks like a pretty cool package.  But I really need to stop buying development kits.  I have finally come to the conclusion that they can put these things out way faster than I can possibly utilize them.

    Mine is off white with a bright white ceiling, but I have a lot of natural light. It's about 3mx3m.
     
    Plain white in a small room makes it seem boxy and under fluorescent lighting the corners look grey. I would recommend a stronger wall colour. It will also show less dirt and help cover imperfections in the surface. Work rooms are high traffic so ideally you want at least semi gloss finish for durability. Ceiling can be matt white.
