This is a very simple esd mat that anyone can build.
All you need is
- Small nail
- Cardboard box
- A three prong cord(must be three prong so that it functions correctly)
- Copper foil sheets that stick(i got mine from eBay, it is used for guitars)
- 1 meg ohm resistor any wattage should do.
- Hot glue gun and sticks
- Solder and soldering iron
First take the cardboard box and flatten it.
Next take your copper foil and try to cover the cardboard to the size you want your mat just leave some cardboard exposed for resistor and nail.
Next solder the 1 meg resistors to the copper and ground on the power cord(the green wire only) and don’t shorten the leads of the resistor yet, poke a hole for the nail to go though and wrap the resistor lead that is directly to the ground(this is where your wrist strap connects)
Hot glue the green wire to the cardboard so the resistor doesn’t break off.
