New Custom Circuit Board Project- ProbeMaster is Born

Last week I finally started designing a project I’ve had in mind for several years. The concept is simple:

A basic breakout circuit board that I can connect to any device under test (DUT) and the result is many spare connections- some with on/off switches already in series and others unpopulated to add any components, connections and measuring equipment I desire.

The PCB design was done in KiCad which turned out pretty great I trhink:

Boards should be here by the end of the week and I will start on the video. As always- source files are in my GitHub repo so you can make your own too.

The intent of this portable kit is to be able to make electronics projects anywhere I go.

The basics are in oscilloscope multimeter soldering equipment some parts and micro controllers. With these or do we know parts in a laptop computer I can build just about anything at least to the prototype phase

With a small amount of money you can re-create this kit with your own equipment starting small you can build it up as I did. check out the video for full instructions.


This USB powered temperature controlled soldering iron actually works pretty well. The TS 800 might be a better choice but this is a lot cheaper and does the job just fine. I really like the non-temperature controlled USB soldering iron’s that are much cheaper but they don’t have temperature control and this one seems to do the job just great
