MPS20N0040D Pressure Sensor Description This is a cheap yet ubiquitous pressure sensor based om a Wheatstone bridge. Unlike the MIS-2500, it requires amplification using an Op-Amp. Datasheet [Download here.] Circuit Design After plenty of reading and experimenting I came up with the following LM358 based circuit that I am satisfied with.

Textile actuator recipe Based on this guide, using Vreeberg's TPE film, and PFS-300. Notes * Using length the same as the fabric, but 30-40% wider. Make the template also longer to account for sealing space. * When following the guide, I always got a tear in the diagonal seal coming from the fold of the silicone. The workaround is to create a vertical seal in

12V NPT Solenoid Valve Info This is a more heavy duty valve, yet still cheap so might not be ultra reliable. It is also about 3 times bigger than the micro solenoid valve, making it less fitting for an untethered solution. Having it normally closed is best for the robot scenario,
