So naked!

 

The past few months have been a blur. Who even knows what the boards in the top row are.

The board on the bottom is an input control board for interfacing an $80 DE0-Nano FPGA development board with modular synth controls. It has:

8 analog inputs

8 logic inputs

8 potentiometers

4 endless rotary encoders

8 LEDs

2 pushbuttons

2 toggle switches

Can an FPGA support all that at once? Yes, because FPGAs are great. I’m a little nervous about the analog input support. I am feeding the A/D converter with 5V power from the DE0-Nano, but the 5V regulation on the Nano is questionable. The board on my desk right now measures 4.71V.
