LC meter with PIC16F628A and Li-Ion battery
I needed a good LC meter for my one of my next projects so I went and built the famous LC meter by Phil Rice.
This LC meter design is pretty old but since it is a perfectly good device there was no need to design/build/debug one of my own. So, I decided to change the original design a bit and now it incorporates Lithium-Ion battery, TPS61222 5V power bosster and MAX1811 battery charger.
