My friend got all excited this morning about LED cubes; a good thing. Having searched and searched I cannot find another supplier for breakout boards for the 40 IO i2c expander that GHI used to sell (which was awesome)
Does anyone know where I can get it?
Also, using the upcoming fez hydra, would it be possible to bit bang the 40 IO so that they produce PWM control of LEDs? Since white multicolor diffused leds in bags of 100 can be had on ebay for 30 bucks I was hoping to be able to do it with 1000 leds (10x10x10 cube) x3 colours (i.e. 3000 PWM IOs)
Before I even consider going forward, can someone tell me if this is even technically possible? I know that the arm9 200mhz 32 bit hydra can handle it but what about i2c.
