I'm low on funds so I'm slowing down on buying so many components until I can get a makeshift lab set up for all of this equipment. I've found my work was moving their R&D department... and a lot of surplus electronic equipment will be dumped since they're moving to a much smaller space. God, I love this place.

So, I might be able to get my hands on an old oscilloscope and a bunch of soldering stations for free. And... likely, a ton of case fans as well. Wee!

I have been doing a crash course on electronic components to make sense of schematics. I really need to study electric and electronic "theory" ...
Before it teaches me.

Exciting! And a little dangerous.
Just need some additional components before I can attempt it.

I've been reconditioning one battery at a time with my one functioning fan. Of course, it's taking a while for it to work properly, so I switched over to a car battery I found in my garage over the weekend. It immediately took a charge, so I let it go for a while, coming back often to check for heat, "bulging" and other signs of imminent danger. The battery accepted a charge and immediately started showing results.
Finally, I'm getting somewhere... I had my little drill battery hooked up to it and running for a couple of hours. This is the strange thing... this little drill battery has awful capacity. It usually lasts about 2 hours.
Last night, I went and checked on the battery 6 hours later... and it was still purring along while attached to this car battery. Was I correct in assuming that the source battery was also being "conditioned" while acting in the source position due to the charging negative being line with the source positive connection? For some reason, it really is lasting longer... even when charging off of its normal charge base.
Needless to say, I was stunned at that result.
