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

Re: Brake vacuum pump controller
can you give some basic specs on the output capability?

Re: Brake vacuum pump controller
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.
