What's on this page?
First, (up top) a list of current specials at our site.
Further down below, our "garage sale"-- frequently featuring "cheap, interesting, broken, surplus, inappropriate, and/or weird things."
6 mm Vibrating Motors with shorter leads
We use powerful 6 mm vibrating motors to drive the diamond point on the Diamond Engraving Tool for Eggbot
. But we accidentally ordered some with shorter leads than will work on the Eggbot-- oops! We're overstocked on these, so they're on sale, over 15% off.
Pearl Case for Bulbdial Clock
: $15 off
The Abalone Pearl Case for the Bulbdial Clock Kit is currently $15 off either when purchased with the kit or on its own
4xAA battery holder
We got a shipment of battery holders silvery leads instead of color-coded (we love color-coded leads). They'll work fine, but you'll have to be careful about which lead is which. We're overstocked on these, so they're on sale, over 15% off.
Neat-o! You've found the Evil Mad Scientist Garage Sale. Below this point, you can sometimes find cheap, interesting, broken, surplus, inappropriate, and/or weird things for sale.
Please read these important policies about the Garage Sale:
- Garage sale items are (usually) limited to stock on hand.
- Items listed as "surplus" or "demo" are sold as-is, and all sales are final on those items
EvilMadScientist Project Parts
- 3 mm Clear Lens LEDs:
You asked for them, so here they are: LEDs that are perfect for Edge-lit Holiday Cards. 10 each of blue and white, superbright 3 mm clear lens LEDs. Brand new and very bright (appear to be 5000-8000 mCd class). Clear-lens 3 mm (T-1) package with flatted side and short lead to indicate cathode. (Note that we also now stock some 3 mm clear lens LEDs on our main LED page.)

- Cheap Toothbrushes
These polypropylene-handle, nylon-bristle toothbrushes are *terrible* if you want to brush your teeth, because the bristles don't spring back very well. On the other hand, they are a good pick for BristleBots because (1) you can angle the bristles by hand-- just push hard and (2) the back side is very flat, unlike more expensive toothbrushes that are rounded-- this makes it easier to mount your battery and motor. Also, they're very cheap.
New, individually wrapped-- and probably even sealed-- but we don't guarantee them to be clean and/or sterile enough for any particular application.
