This goes in the general modding and electronics section.common resist printing techniques:first method- printing etch design to laminate and using photo etch paper to add traces (best results)second method- use a sharpie marker LOL (cheapest and poorest results)third method- PCB toner transfer paper (not the most expensive but it works wellfourth method- glossy magazine paper used as toner transfer paper (cheap and work well but unreliable)common acid etching techniques:first method- Letting it sit and slowly agitating the enchant in the board (slowest)second method- Sponge wiping the acid over the traces (fastest and uses the least enchant but risks wiping the ink/resist off)there are enchant acid concoctions that i know of that i will not share because you can make yourself go blind or kill yourself with the chemicals.Stick with the ferric chloride and HCl solution from radioshack
IP hear everywhere that the sponge method can etch a small sized board in up to 1 minute. I have tried it multiple times and found that not to be the case... i was outside doing one of my nand flasher boards for up to an hour... it takes rediculously long and i had the bottle of ferric chloride sitting in a container of boiled water.
