My first red burner w/pictures

[thewaitinggame]

I finally have my first red burner. I used the dorcy jr. for the host and Kenom's guide was a great help along with everything else on the forum. I have some pictures I'll post of my burner. It lights matches, pops baloons(17 feet so far) and burns paper no problem. I made a 1 inch dia. alum. heatsink for my housing that has a sleeve that fits inside down of the dorcy's head a 1/2 in. The housing and heatsink is held in place by a 4-40 screw. Killed one diode in the process but the second one is still going. I tested it at about 260ma's. and am using 5 ohm resistor and a cap. Hopefully I tested it right because I'm still new to this and electronics.
here are my pictures

and again
sorry, i wanted to post this all in one post but it wouldn't let me I think because i'm not at 20 posts yet.

Nice, is that a SenKat diode?

 

[thewaitinggame]

thanks and yes it is senkats. I measured it around 260 ma's. I just edited the top post and put it in there because i didnt think someone would have look that quickly. I used a cheap harbor freight meter at first and didnt trust it so i borrowed my dad fluke meter. Good thing because the cheap meter was measuring 100 or more ma's higher.

If you just got your diode I think you should check this thread, you see SenKat got a bad batch of diodes and some of them die at currents that are considered to be safe for the good diodes. So it'd be better if you turned the current down to about 180mA.

Yeah I just got it a few weeks ago and my first one from him I got was back in december, not that it matters because that one is dead. I might check the numbers first even though it will most likely be the bad batch. Thanks for the heads up on that one.

I like the way you did the heatsinking...very nice job...

 

[desslok]

I learned the hard way the importance of heatsinking. Thats why i recently ordered one of Jayrobs. Nice work on yours!

You should really put a proper driver in that for some sort of lifetime... if you don't think you can manage making one small enough, PM me as I make custom circuits for things like this on the cheap

I managed to get my heatsink into the cap of the Dorcy ;D
