This driver...what to call it? I don't know--it's pretty crazy though. It was custom designed with this build in mind, with the goal of driving those Luminous LEDs hard.
It puts out about ~10A constant current output from 2S cells and has low voltage protection, temperature protection, and very low drain when off (designed with momentary use in mind). It is a 4-layer board, with maximum thermal performance in mind. I ran them continuously without a heatsink until the temperature sensor kicked in (~80C), then I potted the big heat generating components for an extra bit of insurance.
I'm really excited to see them run with the luminous LEDs in those big reflectors.
I lived in Iowa once. Fort Madison, Belle Plaine. Did a lot of fishing in some of the lakes and larger ponds there, all over the eastern and southern parts of the state. Loved the fall, with all the migrating flocks. Sort of miss it, compared to here.
More photos in the bottom of the OP. It's getting there slowly. I don't have much time now. I got a job and signed all the paperwork today.
It is so ironic. Where did I end up? Right the hell back where I was in my last job! Carrier sold out and Trane came in and bought it. So, it's still big air conditioners, just like it was. Same guards were hired back, more or less. Same guard shack, same location, different guard company and it took them all this time, to get it up and going.
It borders on idiotic! The new guard company is G4S, (Wackenhut). I will say, it's the most paperwork I have ever seen in my life. Over 1-1/2" stack of papers to sign and initial. Then a week of training. Crazy stuff, but it's a job. Basically the same pay too. Well, if it gets me to 62, that's all I really need. Once I hit 62, I'm taking retirement and continue to work part time, till I decide what else I want to do.
