DIY Arduino or "The DIY-Duino"

Step 12: Etching - Materials

Jug of Muriatic Acid
You can get this at the hardware store.

Container of Laquor Remover
This is for if you make mistakes on transfering your pattern.
You can remove the toner and try again.
You can get this at the hardware store

Container of Hydrogen Peroxide
Any Grocery Store

Standard kitchen paper towels
Use for the ironing, agitating the acid solution, and removing the toner with the lacquer remover

(2) Plastic containers
(1 for the acid mixture, one to rinse, one to bathe the PCB in hot water)

Acid disposal container
Size this, depending on how much you're using. See below on disposal.

Pair of plastic dishwashing gloves
You can often find a better, more durable pair of gloves at the hardware store -- right near the muriatic acid oddly enough.

Other Protection
Breathing and eye protection are essential.

1/4 Cup Measuring Cup
Use one that you don't mind being destroyed. Once you use this to measure out the Muriatic Acid, It should only be used for this purpose. NEVER use it to measure food again.
