Here’s how to build simple animatronics using inexpensive hobby servos and the build controller kit. I wanted to keep that as simple as possible so there is no programming needed and the electronics are kept to a minimum so that anyone should be able to do that with a minimum of tools and experience…

Make you dog light up during your night-time walks! Still on an LED high (and still have a lot of LED stuff left by from my first project), I decided that it would be helpful to form some sort of light doohickey that I can attach to my dog’s collar when I walk him at night. His black fur has a nic…

A cheap (and I mean really cheap!!) Mini Indoor Stunt Kite.
Made from:

Drinking Straws (thin)
Plastic Bag (pedal-bin Liner, the thinner the better)
Cotton Thread (strong white, but any will do whether its strong)
stick (balsa, or anything sticklike and even from tip to tip. no taper)

Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.
Using attiny2313.

Scheme

Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for resetin…

A pie tin, a sheet of aluminum foil, and a little glue to assemble a spherical reflector. I signal it a Reflexor.

I first made one of these around 1980 and I am unable to recall the circumstance of my inspiration. It’s quite easy to assemble and the results can be quite good depending on the care y…

Mostly for scientific design. whether looking for a challenge invent a hopper for it or something like that. All mods welcome
