Picture of Easy Squiggle Bot

Don't let the number of steps in this Instructable fool you. This Squiggle Bot is as easy as advertised. If you have all of the parts on hand and any experience soldering wires together, you can probably build this bot in five minutes flat. So, what are you waiting for? Amaze your friends and scare your cat with your very own drawing robot!

I've just bought a packet of phone vibration motors to make some toothbrush bots. With my 6 and 8 yo sons. I'm thinking they'll be able to drive this as well, but I'm going to add a string anchor so it doesn't wander too far and draw on my dining room table

Here's a couple low-budget wind-up versions I made a dozen years back: http://jeffwoodbury.com/gall/gal.php?pgid=critters

i made one of these without the fan because i didnt have one on hand so i just used a high speed motor out of a printer i took apart a while back with a weight on the axle and it worked great
could you use some other type of stilts to avoid drawing everywhere? I dont have much paper.

Love the Squiggle Bot!
very cool, if I had that fan I'd build one now.

Where can I get that brand of fan?

Radioshack sells these fancy red and black ones, but any computer fan will do.

really cool idea, thanks!

the only thought i have would be that it might overheat the motor if you leave it for too long... i dont know though... i wonder if you just added some weight on the side of one of the fan blades it might do the same thing

ill have to test it

So why bother with soldering anyway? Twist the wires together, tape to prevent a short.

It's a more reliable connection, but you can do that too if you prefer not to solder.

Keep these ideas coming ^^ This is perfect for 'Project Night' where my 5 year old son and I spend some time together building goofy things and I surreptitiously program him to be a tinkerer.

Much thanks, I'm looking forward to building it.

Very COOL imaginative MacGyver like application of simple materials.
But what a horrific way to treat a nice fan :-)
Does tilting the table do anything ?

I agree with you
