Sure! The platform is called NeuroBytes; I don't want to run afoul of the Code of Conduct rules so I'll try to keep this description brief, although to be fair they aren't really for sale (at least not yet). Essentially, each NeuroBytes board has five input connections ("dendrites"), each of which directly ties into an ADC line on a microcontroller. In certain operating modes, the NeuroBytes will poll the voltage level present on these lines and use it to change internal membrane current, causing the board to fire once a preset threshold is exceeded (and then increase in firing frequency as the membrane current continues to increase). I made a quick video a few weeks ago using a Dimmer and a Bargraph bit to illustrate the behavior that might be helpful to watch, but things get a lot more interesting with light sensors and a bigger neural network.
Currently, I'm isolating the littleBits and NeuroBytes power rails as shown here (3-rod eye model, not showing the downstream neural network for simplicity), so the two platforms only share signal and ground pins (red = VCC, blue = SIG, black = GND):
Ideally, I'd like to eliminate the wire connections along with the littleBits USB power supply on the left; once I add additional photoreceptors and sensors the wiring gets a bit overwhelming in the eye model, and it's also a pain to use two power supplies. The newest NeuroBytes power rail runs at 6vdc (as each board has a built-in LDO), so I'd add a regulator to the littleBits-->NeuroBytes adaptor. But... I wanted to see if anyone else has run into this problem, how they dealt with it, what kinds of issues they had, that sorta thing. I'm particularly concerned about a user trying to power the littleBits modules from both ends, and the potential damage that could do to the boards.
Thanks for your help, @JackANDJude! Let me know if you need any more info.
