The under sink water filter was in need of organization and cleanup so I designed and printed a set of brackets to get the filter off the floor and mounted to the wall. I also found the tight spacing between the WHEEDF filters in the WHADUS5 filter housing makes unscrewing the filters for replacement difficult. Therefore I designed and printed a filter wrench to solve this problem.
Read More Whirlpool WHADUS5 Filter Mounting BracketsWhile designing a sensor breakout PCB I decided it would be useful to include power input protection in the form of reverse voltage and overvoltage protection. This circuit is a combination along with slight modification of two circuits I found online. In this article I build up a prototype for functional testing and also perform some circuit characterization. This is a prototype circuit that I plan to implemented in future projects.
Read More Circuit Protection With Discrete ComponentsI set about making an isolated probe for my CNC 3018 Pro Router. Isolating the probe protects the controller from high voltage shocks due to static discharge and voltage generated from the spindle motor.
