Wii Nunchuck Adapter

This tutorial is for all those people who have an Arduino and want to use there Wii nunchuck as an input device, but don’t really feel like cutting open the cord and ruining the nunchuck FOREVER!!!!!!!!well you’ve come to the right place!

Step 1: Supplies

These are the supplies you will need
most can be found at radioshack and at hardware stores.
If you cant find any etchant solution I made my own on STEP 6.
+ iron
+soft gloss photo paper
+wii nunchuck
+brake cleaner
+etchant solution (is makeable, see step 6)
+double sided PCB .062″ thick (you do have a bit of lee way)
+hack saw

Thanks to icecreamterror who made a pdf version of the pcb here’s a link
http://www.mediafire.com/view/?h81q6efr03sw326For those of you who want to do it old school style…
start by downloading DipTrace
and the Wii Nunchuck layout
1. install diptrace by following all the on screen instructions
2. Start Diptrace
3. go to file>open and locate “wii_nun_chuck_adapter.dip” (image 2)
4. click open
5. go to view> click mirror (so it is checked)
6. now it should look like image 3
7. Load a piece of photo soft gloss paper into your printer (image 4)
8. now go to file>print> and select your laser printer (image 5)
9. press PRINT.
10. now you should have a nice looking transfer.
WOOO HOOOO we are almost there. sorta

Step 3: Preping the transfer

1) No that you have your printed sheet of PCB transfer. pick one and cut it out like i have in image 1.
2) Now what we want to do is fold the paper so the two sides line up. you can use a light to help you look through the paper.
3) Once its lined up make a nice clean crease. (image 2)
4) Now we use some tape to make sort of a tube that the PCB will slide into. (image 3)
5) The transfer is ready
Next step is to cut and prep the board.

Step 4: Cutting and preping the PCB

For this step I don’t have very many pictures but its pretty much straight forrow
1) Remove your new board you just bought at radioshack from its bag
2) I recommend cutting out one of the transfers and using it as a template to get the dimensions right
3) Place the transfer on the corner of the board and with a knife score around it
4) Then I placed the board in my vice and used a hack saw to cut it
or if you can get your hands on a band saw that would be much easier
5) Once the board is cut out. (image 1) take a piece of 800 grit sand paper and sand down the edges
6) Finally clean of the board with some rubbing alcohol or water making sure to dry it good if used water
next we will transfer the design onto the board

So we have our tube like transfer and out cut to size board.
1) Take your board and slowly slide it into the transfer
2) Next use some object (i used a paper clip) to try to adjust the board so it lines up with the design
3) Now place the transfer and board on some surface. I put a paper bag down so it wouldn’t mess up my desk.
4) Now what ever iron you are using turn it up to the HIGH POSSIBLE SETTING (image 4)
5) Once the iron is warmed up take it and press down on the board with about 20lbs of force for 20 seconds. (image 5)
6) Turn it over and press for another 20 seconds.
7) Turn it over again and let it cool for 1 minute or so and press for another 10 seconds.
8) Turn it over again and press for another 10 seconds.
9) Let it sit for 2 minutes.
10) Now you can cut the tape and peel off the paper. hopefully the toner adheared to the board. (image 6)
11) Now go to your sink and using a paper towel and scrub off the white paper until you can see your crispy black lines.
12) If not use the brake cleaner and clean off the PCB completely and start over πŸ™

PS: If you are lost in any of these processes this is a good video showing you how to transfer your PCB design.

Now we are almost done. WOOO HOOO!!!!!!!
