: A number of steps have changed, since we've started getting professionally produced circuit boards and screen-printing the design on the insides of the box. All the old photos are still here for reference purposes.
Ah, the classic Super Mario coin block. So tantalizing with its mysterious question mark - just a gentle bump with your fist will reveal its unknown contents. Will it be a lowly coin, the rare vine, or perhaps a power up? If only such a thing existed in real life...
WAIT - IT DOES!
OK, so it doesn't actually
spew coins and mushrooms, but it does light up and play some sounds that are sure to make you smile.
This Instructable assumes you've bought one of the kits for sale on Etsy
. Here's what it will contain:
- 6 yellow acrylic laser-cut exterior pieces
- 4 white acrylic laser-cut interior pieces
- a number of black "shadow" elements for the interior
- custom printed circuit board
- 4"x4" touch sensor plate
- ATTiny85 microcontroller
- 10 extremely bright LEDs
- 10 68-ohm resistors
- 2 NPN transistors
- an 8-ohm speaker
- 2 100-ohm resistors
- 1 10M-ohm resistor
- 5v USB wall wart
- 12' two-prong extension cord
You're going to need some tools and supplies to get this build done:
- a soldering iron and some solder
- a hot glue gun (preferred) or some double-stick tape
- superglue - the brush kind is best
- a pair of diagonal cutters or wire cutters
- a wire stripper or a knife
- a few short pieces of wire
- masking tape (optional)
- spring clamps (optional)
- a vise for holding things in place while you work (optional)
