Great project John.

You have a lot of fun toys to play with.

Favorite parts: Using the water filter as a compressor tank and explanation of how you increased the deadband to prevent over-cycling the motor.

Hi John,

Great post and this one would even qualify for the Project14 sensor competition currently in progress. I like how your interest in a scavenged board led to experimentation, recollection of a post by Jan, and eventually a working circuit and demonstration of compressor output pressure control. Nice use of the second op-amp as a comparator as well.

John,

Excellent control system experiment. I found your development process and testing to be very good. I really love an experiment that crosses multiple domains (electronics, mechanical, pneumatic).

Well done!
