Dear Wouter-Jan,
I have thought of sorting this out but lack the time.
I was planning to drive a Bartels micropump (https://urldefense.com/v3/__https://www.bartels-mikrotechnik.de__;!!Dq0X2DkFhyF93HkjWTBQKhk!Fl3QnX0kaNDkjIkVK9SmqIit_hwo6gAz_80TvXrnCYlblfot4FCEfutfKJLK6fz-vnsk1Y58bAmx7w$ ) with an Arduino (or better, in 2021, an Adfruit Clue which can be programmed in Python and has a teeny display).
Could also use a Curiejet diaphragm pump.
Ought to be able to make something 100x better, but it needs some time to develop. I got in touch with Bartels and they are helpful.
