Wanted to share with you a little board that I designed for Zapatero. It's a vacuum pump controller or in more general terms a trigger amplifier that switches on a MOSFET when its input goes above roughly 2V and switches off when back under 2V. There is some low pass filtering to prevent oscillation. The MOSFET can drive a relay and that can drive the pump or the MOSFET can drive the pump directly - it is large enough.

The threshold is designed for the VW pressure sensor here: viewtopic.php?f=9&t=335&start=70#p9183

If people are interested I'd get some more made and put them up on the shop

can you give some basic specs on the output capability?

I've tested with 5A that does not generate noticeable heat. So 10-15A in the typical short term bursts should be possible. Will test in Polo later.
