Running same coax to 5v relays.
Separate grounds, planning to switch single ended/differential

Unleaded started appearing all over the place

Identified, fixed

clingFilm+rubberBand

Attaching balanced microphone cables between relays & ADC connector, to make it more flexible and less fragile than coax (no buffer this time) AC/DC caps soldered on the other side

Trying to keep the inputs short and sweet

ADC DIP sockets, some headers, connections & secret markings :S

Something is brewing, picking up noise, might be relays

With faster ADCs will be making proper PCBs this is just some playtime

Can you spot RGB LED LDR variable resistor, controllable via PWM? more:
