Electricity is great, and it is even better when you design an electrical project start to finish including the electrical source. This system is broken up into 2 sections by RimstarOrg the first video above shows how to build a simple high voltage spinning ball bowl. It uses the velocity of the ball and the principle of attracting opposite charges to allow the ball to move from one strip to
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
Looking to kickstart your prototyping? JIGMOD might be just what you need. You still get to use your speedy breadboard but those devices that just don’t quite fit can now be a compact module that is held securely over to the side. Moving your prototype around from place to place will no longer be a stressful time since with this system it is much more likely to survive. “How
John Schuch does a Solar Security Light Teardown, the device is to be used in his HackaDay Prize Entry. It often makes sense hacking an off the shelf product instead of designing and building your own especially when the device needs to last in the outdoor elements. John has seen first hand what happens to unprotected powered electronics when exposed even for a short time to the elements on his
The Eyedrivomatic is a system that lets you Drive a Wheelchair using Eye Tracking Technology. Â “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
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
Pax Instruments Inc is making an open source temperature datalogger. Charles made a great video going over the entire current prototype showing off the tech inside and reasoning behind many of the build and design decisions. The device is using a MCP3424 A/D, it has 18 bits of resolution so your measurements should be nice and accurate. There is also a lot of thermal management that has been done
