Great news Trumpy! I've made quite a few pieces of test equipment that the guys at work enjoy using. Not a one of them ever thought that what I made was store bought. Even without pictures, I know your craftsmanship must be exceptional. I can't wait to see pics though. I'm curious if you chose LiPo batteries or some other high energy density source.
I suspected that you would probably get good results with those little boost switchers. I know that if you priced out just a few of the components, you saw that you couldn't build one, without spending several times what you paid.
Did you end up writing a manual for your tester? I love to design/build things but hate writing the manuals. My last gadget was a 19 Cycle Timer / Current Source for ballistic relays. The manual was 6 pages, including descriptions, photos, schematic, and layout drawing. The only fun part was watching the guy's faces, as they were reading the circuit descriptions.
