If any of the info on this website was useful for your projects or made your head spin with creative ideas, and you would like to share a token of your appreciation- a donation would be massively appreciated!

Your donation will go to my Robotics Fund, straight towards more sensors, actuators, books, and journeys. It takes a lot to continue building these robots, and I’m really thankful of everyone who helps encourage me along the way.

Parts from Old Scanners

Thanks to the electronics I picked out from the Eco-Quartier e-waste drop off, I had 5 huge old scanners to scavenge parts from!


Old scanners are a great place to find stepper motors (like the ones I used for Scrumbleflit)!




The mirrors are also spiffy to use in laser projects:


And the cold cathodes are always cool :)


One of the things that I found funny was that you could almost see a progression of time from when the scanners were made. Two of them had the ULN2003 as a DIP format, whereas the other three were more new and used the SMD format. However, those three new ones were not constructed to use screws. It was molded plastic that clips together. This kind of makes me think, who on earth thought it was a great idea to not use screws anymore?

There was also a scanner that did not have a cold cathode like the others. Weird!


These are some components that I’m not entirely sure what they do, but they look really cool:


All in all, this was pretty fantastic to get 5 new steppers to use on a robot. I’m really excited to use the mirrors for some funky lighting effects too! It makes me extremely happy to use recycled steppers from old scanners. YAY FOR FREE PARTS! 😀 You can see more photos on flickr!

If you are thinking that you need more motors for your robot, just get out there to your local e-waste area and find some old scanners to take apart! Be creative and recycle 😀

    The unknowns in your last photo here are the CCD devices similar to digital camera capturing surfaces and the power transformers.
