Basic Circuit Bending




Take your old electronics and make them scream with glitchy goodness. This an extremely easy project and makes and great project for first time solderers.

From I was taught circuit bending is taking electronic devices that make multiple sounds and wiring in switches to set off glitches, or loops. This was my first project with soldering and it makes a great first project. Check the end of the instructable for a video.

Step 1: Gather Materials and Tools

This step is fun; you can choose almost any device you want. The one I chose was VTech Talking Little Smart Spelling Book.

VTech Talking Little Smart Spelling Book
a switch (not necessary but makes things more fun)

Soldering Iron
Dremel (if you want to make a hole in your electronic for the switch)
Screw Driver

I wasn't sure if this would be a tool or a material so it gets its own category.
Super Glue

Step 2: Open It Up and Find the Cool Sounds

Take your screwdriver and undo all the the screws in your device. Now take a piece of scrap wire and bend it into a rectangle with no bottom. Now place each on the soldered areas of silver stuff (don't know what they're called, I never soldered before). Do this until you find a set of dots that make glitchy sounds. Remember these spots, they'll be necessary later.

Step 3: Setting Up the Switch

Did you remember your two points? Good this is where you will put that memory to use. Take out your soldering iron and solder two pieces of wire to the points. Make sure that the wire is long enough to extend to the edge and beyond of the devices casing. Once the solder cools set up your switch so that when you press it the glitch/loop activates. I won't give specific instructions for this because everyone's switch will vary. If you have questions about setting up your switch please leave a comment. Before proceeding any further test your switch. To do this turn the device on and press your switch. Does it make a glitchy sound? If yes you did it right, if not you screwed up somehow. In the screwed up somehow Go back to step one and try again. Go directly to step one, do not pass go, do not collect $200. For those of you that succeeded please proceed.

Step 4: Put It Back Together

Before we start screwing things back together lets dremel out a section for the switch to be. To do this measure your switch and dremel its shape into the edge of the case for your device. Fit the switch in place and superglue it in. Once the glue dries screw it back together.

Step 5: Test It

Ah, the moment we've all been waiting for. The test. This step is pretty self-explanatory. Turn your device on and press the switch. It should be making weird noises. If you don't know what I mean check out the video below.

    Oh my gosh, I had one of these! The glitchy sounds are denfinetly an improvement.

    there is a video in the last step, i could post more sounds but the switch i wired is a loop, you heard all the sounds it was set to make

    I could be wrong, but I think that just shorting random pairs of solder points could pretty much distroy your electronic device. Obviously, this particular toy is not something you care too much about. But it's important to note not to do this on your iPhone, or anything like that.

    I wanted to be the first one to comment, I'm glad you made this annoying toy do something funny! I have no idea how you do it but it works! Great Instructable, easy clear directions, good photos and video. Where did you come up with this idea?
