Water Shut Off Valve Project

at 4:31 pm. Filed under Cool Gadgets, Electronic Hacks


This project allows you to automate the filling of water containers. In this case the need was to stop filling a horse water tank and automatically stop when it has been filled. A few stainless steel clamps are used to sense the water by conduction. The circuit is running off a 9 volt battery, it is powerful enough to activate the 12 volt relay and a voltage divider is used to make the 5 volts that the microcontroller needs.

“This is a very simple project that only uses a few electrical components and some PVC pipe. This is the first project that I have built using an ATTiny 85. It is a very powerful little chip and I will probably have many more projects that use it. An Arduino can be used in place of the ATTiny85 and the same code should work.”

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.”

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.”

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.

Power Driver for DVD Burning Laser

at 11:44 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


If you have a few dead DVD players sitting on the shelf collecting dust you could rig up a quick and dirty power supply to make it into a burning laser. There are laser drivers available but what is the fun in that.
