I got my brown clip in from eBay. I had a hard time getting a connection with the chip on the driver, I'm not sure why. It seems better made than the blue ones, but not as easy to line up with the leads from the chip. I was able to flash a new program into the chip eventually, but when I attached a spare LED to test it out, I got nothing. No light whatsoever (LED works; I checked). At one point in trying to communicate with the chip AVRDUDE gave me some kind of error about the fuses being reset to 0 and did I want to reset them. I think I said no because the command to upload the program already includes fuse settings, but I think the chip may be burned out. Or I could have burned out the chip with some bad soldering, but I checked everything I could for shorts and continuity and couldn't pin anything down. Seems like if there was something wrong with the chip that AVRDUDE would let me know.
That was my last spare driver, so now if I want to try anything I will have to take a driver out of an existing light. I did just this with my Mr.Lite BLF-Y4E but when I saw the board and tried to hook up the clip, I remembered reading about a capacitor or something in the way. I repaired the inductor that I accidentally knocked loose and the light still works at least.
I may order some new drivers. Still not sure how I will be able to rewrite and compile the BLF-VLD to get my "perfect" light: 2-mode with a programmable Low (no sense in programming High; I think having 1 programmable mode should make things a lot easier), but can't really play around with it until I get a driver connected.
