Thoughts and ideas.. I'll add things here as I think of it, or as I discuss with people. I'll also post updates of further experiments and improvements.
The lead could be extended and if used carefully, it could be used to solder in places that many traditional irons could not reach.
This could be made into a tweezers. Pinching the part between the leads. Neato.
I should just replace the jumper wire on the power supply with a switch.
I could probably replace the PC supply with a battery pack. Sure, I would make it something like three car batteries on my back, but a few AA might work.
The tip does cool nearly instantly. The carbon radiates the excess heat off really quickly.
The middle spacer on the tip should really be something that won't melt. Let me know if you have any good ideas.
EDIT: Regular glass.. why didn't I think of that....
To regulate the power to the tip, I could use a simple rheostat. Something like a dimmer switch or the pedal from a sewing machine.
This is just a first pass at making something of this sort. Its delicate and somewhat unwieldy at the moment and I broke the lead at least three times while I was testing things. I leave it to you to make a better one. If I don't do it first.
I have now procured (Dumm dum dummmmmmmm) Two AA batteries I am going to strip for the carbon cores. If it works out OK, I'll update with pics and such.
This was fun and cheap.
Many thanks to my lovely future wife Jackie for picture-help. Come check out our other strangeness: http://www.lovesickrobot.orghttp://photozz.wordpress.com/
