Toner transfer

Those that can't get their hands on expensive printers may want to look at YouTube user Pareekshith P's method of creating circuit boards. His method is known as the 'toner transfer method', which is basically a simple etching process. Users first draw their circuit designs using any CAD based software and print out the design using plain black ink on glossy white paper. The design is then placed face first on top of a sheet of copper substrate, which then is ironed on and then thrown into a boiling pot of water for 25 minutes or so. Once nice and tender, the paper is then peeled off and the board is put into a container of Ferric Chloride for 15 minutes. Scrub off the black ink, drill the trace holes and you're finished.
