Toner Transfer and Muriatic Acid Etchant: Making PCBs at LVL1


Brad Lyuster of Louisville’s LVL1 hackerspace wrote an excellent guide to etching your own PCBs.

A few months ago, the spoiled electrical engineer that I am, I never would have considered making my own PCBs. Any project worth taking off the breadboard was worth sending to China to get made “right.”

Of course, there isn’t always time and money to send something to China. Today’s installment is the Sumo-bot board I’m trying to put together for the Hive13 sumobot competition. Unfortunately, it doesn’t look like poor Snoopy bot will make it to the ring, but the board making process itself is worth talking about.

  1. s’funny we still use the alchemists nomenclature:”Muriatic Acid”. When it’s just good ol’ (aqueous) Hydrochloric Acid in chemistry circles today (i think there’s some presumed etymological connection between salt (Na)*Cl* -> brine -> “marine” -> “muriatic”)
