Hackaday Prize Entry: The MultiSpork

This is a cool idea — and I like to see people trying new things to see what works, but I wish they were using better silicon. The 20-channel reconfigurable I/O is neat, but I can’t think of many cases where a a dedicated 8-input logic analyzer / 4-channel scope / 2 channel AWG wouldn’t be sufficient. A fixed layout like that would be much lower cost than using that crazy-expensive Maxim part. That part can only do 400 ksps on the analog side, and I don’t think they’ll be able to get more than 1 MHz of digital I/O performance from a single channel, and that’s going to decrease dramatically as you add more channels. As a result, you end up with a scope that doesn’t even have half a megahertz of bandwidth, and a logic analyzer that can’t even sniff a low-speed 1 MHz SPI session, and would probably struggle to sniff i2C traffic, too. I understand that it’s small and inexpensi...
