Eyedrivomatic – Drive Wheelchair using Eye Tracking Technology

Eyedrivomatic - Drive Wheelchair using Eye Tracking Technology


The Eyedrivomatic is a system that lets you Drive a Wheelchair using Eye Tracking Technology.

 “Eyedrivomatic’s software is in two parts, firmware for the arduino in the brain box, and a pc application which I have written in processing. Many eyegaze users will have software on their computer for communication and computer control. Our intention is that the pc software will be accessible through the users own computer control software, or directly, using the eyegaze equipment’s mouse emulation capibilities. At the moment, it only works with one computer control package – Grid2. Grid2 has allowed for rapid development of the pc software, and I intend to perfect it before writing the stand alone pc application.”

Solar Dancing Pumpkin Teardown

at 11:40 pm. Filed under Teardown



Ever see a little solar dancing flowers on someones desk? This Dancing Pumpkin is the Halloween version of that little decoration. I spotted it in a store for around a dollar and it was wondering how they could make it this cheap. Watch the video to see what’s inside, not knowing their was a coil glued to the base I almost destroyed the coil while with my screwdriver while trying to pry the bottom off. Like all other mass produced items like digital watches and cheap calculators there is a mystery IC bonded directly to the tiny PCB and covered by a blob of epoxy. The construction is very simple it consists of a solar cell, a capacitor, the magic IC, a coil and a magnet.

The pumpkin dances when the pendulum with the magnet is swung back and forth. The position of the coil is slightly off center of the magnet which allows the coil to gently start pulling the magnet towards the coil with small pulses. After 5 or 6 pulses it has enough momentum to continue with a large swing. The unit works fine with as little as 500 lux and draws only 85 micro amps when in constant operation. I am very impressed that this cheaply mass produced item can swing with sufficiently low resistance to operate reliably.

DIY Motorized Combo Lock Cracking Device


Have a master lock that you forgot the combination to? Samy Kamkar shows us how to get in with a nice little motorized combo lock cracking device

“Combo Breaker is a motorized, battery powered, 3D printed, Arduino-based combination lock cracking device. It is portable, open source, 3D models provided, and exploits a new technique I’ve discovered for cracking combination locks in 8 attempts or less, but in an even more exciting, automated fashion.”

ICON A5 Recreation Airplane

at 1:44 am. Filed under What Were They Thinking

ICON A5_2 


The ICON A5 costs about $200K which is cheap by plane standards and with only 20 hours of flight time to get a pilot license needed to fly this plane I can see this open up a great new hobby for some. Here is hoping this is just the first step into making these planes cheaper and more accessible to the average Joe.

A Look inside a Daisy Wheel Typewriter

at 11:20 pm. Filed under Cool Gadgets, Teardown


This teardown that thegeekgroup did reminds me of technology gone by. There are lots of variations of this. The one I used had a different type of ink ribbon cartridge it was a ink impregnated cloth that would auto recycle so your text would just get fainter and fainter over time. If you want to change the font you just replace the font wheel. I am surprised that there is no sensor to prevent it from typing if there is no font wheel or ribbon cartridge. Interesting that there was no cover on the EPROM. I am thinking it must have been replaced by a field tech since I am sure it would have been covered out of the factory. One thing you can see is the construction and drive train was designed with serviceability and longevity in mind. I would like to see what it would look like if it were built today. It would weigh about 5 pounds and last about a year printing a few pages a day. With a bit of work 2 of these printers would make a nice small CNC machine.
