If you've ever used an Xbox 360 slim you've probably noticed that the power button is touch sensitive. All you have to do is tap the power button with your finger and the Xbox 360 powers up. This instructable will show you how to give your Super Nintendo a touch sensitive power button. This is a fun mod to make your Super Nintendo a little bit more futuristic.
Caution: I am not responsible for any damages resulting from this mod. This includes hurting yourself, damaging your Super Nintendo, Arduino, or anything else!
Step 1: The Parts
1. An arduino (I used an arduino uno)
2. A relay switch with a 5V coil voltage (ouaz -ss-105d)
3. 1M ohm resistor
4. 1K ohm resistor
5. An NPN transistor (2N222)
6. A diode (I used 1N4148)
7. A small PCB
8. Aluminum foil and a paper clip
9. Wire that will play nicely with your arduino
10. A plastic bag
Additionally you should have access to a 4.5mm Nintendo security bit for opening your Super Nintendo, a phillips screwdriver, and a rotary tool.
Many of these parts are substitutable. This is just what I happened to have in my parts box.
Step 2: Preparing the case
When the screws are out, flip over the console and take the top half off. As shown in the second picture, there are little plastic pieces that must be cut off to make room for the arduino. They are not essential parts of the case and can be cut off without ruining the integrity of it. Use a rotary tool to cut them off. If you don't have one you can probably cut them off with wire cutters.
Now that the case is finished we have to get the power button ready.
