Switch adapted toys are expensive and the variety can be only determined by a few companies that essentially do what I have done here. Although like many toys last only as long as the kids are interested in them. As switch toys go this has it all for simple cause and effect. The vibration, motion and auditory stimulation are great. I have made lots,lots,lots of these and they fly off the shelves. They can be great cause and effect play, interaction and therapeutic toys for training kids with different mobilities!

Step 1:

For this Instructable you will need the following:
1. Drill with 1/4 inch or drill bit
2. Glue Gun
3 Soldering iron and solder
3. wire strippers and two peices of small guage wire
4 Jelly bean Switch or similar to test your work
5. small electronics sized phillips screw driver
6. giggle pig, cow, dog or the like.
7. 1 female 1/8 ' mono jack port

Step 2:

remove all screws holding the pig together , being careful not to separate connected power supply. Now remove screws holding the blue vibration motor housing.

Step 3:

now with the housing out of the way we need to unscrew the switch located under the nose

Step 4:

here is the switch exposed when the black is depressed it activates. we will be soldering two wires, 1 to each side. (sorry its a bit blurry) the two orange wires are my wires I soldered on top of the existing blue ones.

Step 5:

Now take the orange wires and solder them to the mono jack tabs as shown, typically I solder these to the two innermost tabs of the jack. This may take some time to solder if you are unfamiliar with soldering techniques, however a third hand (small clamp) can be helpful here, I didn;t have mine during this one.

Step 6:

Reassemble the blue housing and test your connection, be sure to take care with the existing wires which can be delicate. Keep orange wires up and out of the way as you are reconnecting everything.

Step 7:

I have found this area to be a good spot to drill your hole to accept the jack ream the hole slightly bigger if it is tight. When drilling the whole take care to not "punch through when a bit drills in plastic it tends to catchn and pull itself in which would not bode well for the electronics if you bust a hole through the board.
