One thing that I'm not terribly good at is soldering. I do it a lot, and I improve every time I work with it. At this point, I mostly work with through-hole soldering, since it's a lot easier to learn with...and easier to hook up without ordering custom PCBs.
Remember that Camera Light project I did back when? (And the actual prototyping, and the concept?) Yeah, I barely do, either. It was a while back. (We've had everything from family emergencies, to illness, to pesky day jobs keeping us hopping around here, with no free time. Yikes!) I did hear from a couple of people that the light had a serious problem, in that there was absolutely no need for a microcontroller.
Now here's a simple, short review of a pretty simple tool: the iFixit Jimmy.
