#7 Cheapo ring LED flash / light teardown & li-po mod

I had been thinking about grabbing a LED ring flash for my camera for quite some time, but finally last week, i pulled the trigger on one. Cheapest of the cheap (from what i could find on the British eBay), but still cost me a bit under 30 bucks.

That being said, it's a reasonably well-featured package: four different coloured diffusers (that go onto the front of the LED ring), eight different size adapter rings (for lens/filter threads, and onto which the light clamps on to), and the control unit that mounts into the camera flash "hot-shoe". Also, the LEDs in the light "head" are split into two halves (ie. left and right), for <ahem> creative effect when using the ring flash for macro work.

The thing normally works on 4 AA's, buuuuuut... given some of the previous posts here, you oughtta have half an idea about my feelings regarding disposable power sources... <wink-wink, nudge-nudge>

#6 Canon EOS 400D / Rebel XTi troubleshooting & repair

I got this old EOS 400D from a friend for about 35 bucks. She said it won't power on, even with a fully-charged battery. Might as well have a crack at it, eh?

On the outside it seems to be in pretty good shape. A bit of dust here and there, but hey, it's about a decade old, whaddya expect? Battery checks out fine, reading 8.15v, so that's definitely not it.

As chance would have it, between being offered the camera and receiving it, i did some digging around online, and i came across this little story here (scroll down to the second half of it). Could i (also) be fortunate enough to only need to swap out some fuses?
