Figuring out the ECB

With the switches finished, I could test the ECB, figuring out how it works. Hooked up the lights, downloaded the ECB interface program for PC, and turned on the power. After some fiddling with bad connections and too tiny wires, it worked super. Found a bug in the interface program though. When setting the trip time, it just go to zero. A bit annoying, but in the aircraft it will be hooked up to the EFIS. Hope the same bug does not exist there.

Have to test the other stuff as well.

Soldering switches for the ECB

Started soldering the switches for the ECB.

Got myself a new soldering iron, and some 0.5 mm solder with led. I have never soldered PCBs before, but with this new equipment it was a piece of cake. The diodes are two colored. OFF is no light, ON is green, and a "blown fuse" is red. The switches will e connected to the ECB.

Crimped i piece of crimping tube around each diode to prevent the feet to short circuit.
