Hmmm... Yes... that would make sense. I think it said that there are no blinky modes in programmable? I'm trying to set up a dedicated camping/tenting/trekking light and it would be nice to have some kind of SOS or other distress signal.
Soldering was actually not very hard. If you have someone to push enter, you only need to solder those 4 pins. That's what I did. My soldering skills are not so good that I would tried soldering those 4 pins on the upper side of the chip. It would have been one messed up driver after that. What I did was solder only the corner pins, which is no big deal, and then write (or copy/paste from flashlight-wiki) the command needed to command prompt. Then I stick the remaining 2 pins to the driver legs with my bare hands and ask the wife to come and push enter. Sorted :)
