Well since I learn fastest by doing (not exactly unique I guess) time to start my next trick. Adapting one of the many curve tracer schematics, probably Metzger's circuit from the early '70s with modifications to an ADC capture system and output to a 320*256 ELD panel. (Because I have one to play with) And also add a serial output to enable transfer to a spread sheet of base current, collector current and collector voltage. NPN first, followed by PNP and then FETs. May add the ability to run scroll bars across the screen to enable readout of calc'd hfe. Since I plan to use full wave rectified 60HZ secondary for Vc, I may have to (I hope) use assembler to capture the individual 320 points per 1/4 wave time for each step.
Any comments are as always welcome. I had thought of putting it into oldbitcollectors contest website, but I already have the gadget gangster for my base platform and more than enough T-shirts, that it would be a just for grins entry. If anyone thinks I should post or blog as I go, say so. This is an endeavor that benefits from kibitzing. Of course I reserve the right to ignore any one at anytime even should the release of magic component smoke be imminent. I will check the OBEX and other resources, but if need be I will pester the experts as needed. Promise. And yes, this will take a while to do. Kinda like Mr. Cash's Cadillac, it will get done one object at a time I am sure.
Thanks in advance,
Ordnung ist das halbe Leben
I gave up on that half long ago.........
