Oooooo, new Tim Hunkin "Secret Life of Components" on YouTube.

#Solenoids & #Relays

Really enjoy his videos, I'm generally familiar with relevant theory and practical use of the components. But his breakdowns and explanations are really good, and his practical use examples fun and often ingenious.

See a crisp packet turned into a speaker:

I want to automate a part of my physical job, which requires me to make sure the pressure in a system is in a specified range. Let's say Voltage=X(deviation +/- 0,02V) (where X is mutable). When I get out of range I need to turn on the pump and open a valve (which will be replaced by #solenoids in the finished system).

Where I get stuck is how to design the #electrical #circuitry to activate the different components, maybe @toroidalcore could help? #PCB #DTA #ElectricalEngineering
