Introduction: Guitar Hero Clone

Ever wanted to play Guitar Hero on your computer with your own home made guitar ? Get ready to play for less than 10 bucks and some patience.

Step 1: Buy a Cheap Toy Guitar

The first step is to go to your nearest Wal-Mart (or the like), and buy a cheap electronic toy guitar with at least 5 buttons on the neck. I found the following one for 9.95$CND.

While you are doing this, download the free Guitar Hero clone Frets On Fire. You can also find on the web all the songs from Guitar Hero I and II! All for free!

Step 2: Hack a Keyboard

For this step, I have modified my keyboard to have a parallel port connector at the back. I recommend you use an old keyboard and place the entire circuit board directly in the guitar (a keyboard's circuit board is usually about 3-4 inches wide by 1-2 inches high), then trash the case and keys.
The trick is track down the traces for 7 keys (14 wires). Though you can use 7 keys of your choice, I recommend you trace 7 keys that are on the same trace (this changes the number of required wires from 14 to 8). Be careful, some cheap keyboards prevent you from pressing certain combinaisons of keys, so 2 or 3 fingers chords might not work.

Controls to be used with the guitar:
Button 1, 2, 3, 4 and 5;
Flipper Up and Down.

I bypassed keys 1, 2, 3, 4, 5, X and Z, by soldering some extra wires to the parallel port connector.

Cut one or two RJ-45 cables (LAN) of about 10 feet long, and solder the wires to the male connector.

Step 3: Rip Open the Toy Guitar

Open the toy guitar and rip off any speakers, wires and processing unit.
Bring your RJ-45 wires from the keyboard to the neck circuit. With a knife, cut the tracing and solder your own wires for the first five buttons.

Step 4: Create the Flipper

Remove two buttons off the top of the case or create your own openings. Cut a piece of strong plastic and fit two legs in the holes.

(I used some sort of plastic piece usually found in the back of drawers to hold them on a track, but I'm sure you can figure out somethin ;-)

Step 5: Create the Flipper Circuit

This is probably the hardest part. You need to drill holes in the flipper legs and pass a long metal rod to be used as a hinge. Hot glue the extremities in place.

Use the existing screws to run springs or rubber bands to go away from the flipper. I used two screws placed vertically in the legs to hold the springs. This will have the flipper come back to a neutral position when released.

Hot glue a long thin piece of metal to one of the legs of the flipper. Glue a connector under the tip of the piece of metal and another connector above it. When pressing the flipper down, one connection is made. When pulling the flipper up, the other connection is made. (My second connector is placed on the speaker's socket)

Run a wire for each part. Make sure the keys used for Up and Down are on the same trace in the keyboard. You must have only 3 wires in this part of the circuit.

Step 6: Wrap Up Everything

Make sure everything is working. Make sure to label all the wires in case you need to tweak them.
Cut a hole in the bottom of the case to run the cables out to the keyboard (if you did something like me) or to the computer. I made a knot with the wires inside the case so the wires are not accidentally ripped off.

Step 7: Get a Grip

Make sure the grip on the buttons is appropriate. Kids tend to hav very small hands (!), so I made the neck a little bigger and I increased the thickness of the buttons. For that I used a piece of kid floor tiles (use different colors at your discretion ;-). I have also cut grooves in the foam so my fingers know exactly where they are on the neck.

The strap is a nice add on so you can play while standing up!

Launch Frets On Fire, connect the guitar, setup FOF so the key settings reflect those of your guitar, and rock on !

(Side note, plan a Esc button on the guitar, otherwise you need the keyboard to be close by)

I didn't bother making this wireless, but I'm sure someone is crazy enough to use a wireless keyboard !!! :-)

Frets on Fire...PSSSHHHHH!!! Why don't you learn to play a REAL keyboard??

(...hopes the sarcasm is obvious...)

he said in the instructable that its for frets on fire

You should be able too, just do the same thing, just make your own drum case (or if u can find one) and add pressure pads, or if ur like me, and dont like to buy stuff, you can try this: 1. find 2 nice sizes of cardboard, 2. cut them out in the shape of a drum 3. stick some (stripped) wire ontop of one of them 4. wrap it in tinfoil 5. repeat steps 3 and 4 for the second peice of cardboard. then solder the wires to the keys just like in this instructable
