This is the penultimate project from Boldport Club before they move away from the subscription model. It is called Capaci-meter and is project #31. I’m really sad to see the Club changing because I’ve enjoyed the projects a lot more than any of the other electronics kits and the PCBs are so beautiful. It’ll be interesting to see where it goes.
After having issues with my Hakko FX-888D soldering iron, I finally did some troubleshooting and by using a meat thermometer I determined the tips weren’t getting hot enough. Then I found the device actually has an adjustment mode which lets it compensate. Works great now and is so much better than that cheap iron I’ve been using for other recent projects.
It’s great when the project produces a useful device like this for testing the value of capacitors.
