Here's another DIY pyrography set up using a battery charger.
Includes Radio Shack part numbers. Set low, and with tips you
make, you can write and draw with it. Set HIGH and you can make
wood disappear - in a bright flash and a puff of smoke.

Watching Graeme Priddle use his version was fun - shazzam!
- and a spiral pattern appears - after your eyes have time to
recover from the flash.

watch the line wrap
