This page will be a centeral page for a few things I design and want to would share them. As I get the pages build I will link to the Github pages and the ebay pages for the parts I am considering selling. PCBs are cheap in bulk, and sometimes you don't want to build up a board yourself.
VTVM Battery eliminator circuit for 1.5 and 3 volt VTVMs. Designed using a switching power supply to run off the switched 100-277VAC line and then a linear regulator final stage.
Needs documented and github page created. VTVM Battery Eliminator
Copy of a Heathkit metal probe shell for RF probes, signal tracer probes, or scope probes.
Waiting on plasitc endcaps to be manufactured. Probe Shell
RF probe PCB for above probe shell.
Needs webpage and github page created.
Open T12 soldering iron controller. My attempt to create a replacement controller for the cheap T12 stations. Uses proper STM32, opamp, and switch mode power supply that feeds 5V into a linear 3.3V LDO regulator.

Toaster oven reflow controller. Started out wit hthe code from another project, very little of the origonal code still exists. Having good results, none of the standard issues with toaster oven designs where the temp cannot ramp up fast enough.
