Electronics stuff

A fine example of the work of 'skilled' Texan electricians. The AC heat exchanger was right above it and condensed water was dripping into the braker box :-(

The guy how tried to snap-in the new breaker didn't push hard enough. So the right rail got hot due to bad contact. The old breaker wasn't up to the current the AC was pulling. Btw. the AC broke down as well and they managed to wreck the replacement compressor right away :-)

Complete chaos. I don't remember if there was a GFI in there at all. During the time my AC was down (ONE frigging weak with temperatures in the high 90s) I was sleeping with the apartment door wide open. Thankfully i wasn't robbed, mugged or even offed.

Once I find time and leisure, I'll put this one into my sick Jyetech scope and see if it works any better.

600 = 25*24 = 5*5 * 3*8 = 5*5 * 3*2*2*2

I'm getting a bit worried. The left one is easy. The right one cries for tons of flux I guess. As my iron's tip is large compared to the tiny pins I'll have to use "flood and suck" for this one. Or maybe drag soldering works too. I've seen many professional videos using tips that have a little cavity forming a little reservoir for solder. This would help a lot, but I can't find a tip for my iron like that. Only the usual pencil/chisel/cone/45° stuff.

The main inductor for a boost converter / LED driver based on the LT1618.

This will be used for filtering the output of a boost converter based on the LT1618.

It contains some errors related to driving the P-MOSFETs.

Arrrrr...

Saving energy. Yay!
