	We then tried transferring it to a solid copper board by printing onto magazine paper and then ironing that onto the board (we lacked the proper transfer film). This sorta worked, but not good enough. We subsequently learned that the magazine paper method works best if, after the paper is ironed to the copper, one wets the magazine with soapy water, loosening the fibers and leaving more toner stuck as you pull the paper off.

MCT used up a couple minutes of company time, toner, and coffee getting one the sheets printed on. Not without some mishaps, the deed was done - success was achieved.

	We ended up spending most of the time just designing the circuit. We based it on the [[Logo\|Noisebridge logo]], incorporating a series of resistors, a speaker, and for fun, an ATTiny25, an LED, and a micro switch. It can be programmed to do things! Look!

			There are a few ideas floating around for how the ATTiny25 can be programmed. One is for the LED to always be on, and for the speaker to make noise when the center button is pressed. It has also been suggested that the speaker play a song (London Bridges Falling Down?).
