I've always wanted an LC meter -- and now I have one. This is an LC meter designed by VK3BHR and presented here.
Another project mostly from my junkbox -- I just needed the 16F628 and 100mH inductor from digikey. I suppose I could have wound that myself -- but how to measure it without a meter! This project went together easily and worked immediately. The enclosure is a plastic box that used to hold a Christmas ornament because I don't have anything better at the moment. It works -- I'll probably keep it in this.
A different enclosure would allow for shorter leads, but oh well. It seems to read my existing caps and inductors properly. I think the calibration step nulls out any error. Considering what it does, there are dang few parts in this project.
