Here are the latest several projects that I've posted. All my projects can be found by clicking the menus above or on the left.

Inductance meter

Some time previous to getting my ham license, I was at a friends house who showed me an LC (inductance) meter built from a kit. It was based on a PIC16C22A, and I certainly do like the PIC mcu's, but decided I would embark on the task of re-engineering my own that uses an Atmel AVR chip, the Atmega168. It's been a journey. Also, I am giving away for free the schematics, firmware, and source code as open source under the GPL.

Desoldering Tweezers

Here is a new desoldering tweezer tool I just made, it's rough and there will be improvements, very likely. It looks kind of dangerous, but it's really low voltage, under a volt, barely enough to register on my digital voltmeter.

These tools cost hundreds of dollars if you want to buy them somewhere, but I made mine out of cheap radio shack parts and junk. The power supply is also homebuilt, which I also use for my hot air pencil . In the lower part of the photo, what looks like sawdust, is a bunch of resistors that I desoldered in just a few minutes.
