The Geek Group has acquired a retired KUKA robot. They have made a series of videos about taking it apart to see what makes it tick. Lots of the pieces will be re-purposed into other projects that they have on the go. That is one massive robot, I would have preferred to see it brought back to life but it is also interesting seeing how all the bits and pieces
If you live in a cold climate freezing pipes is a common concern. A frozen pipe is more than an inconvenience since most pipes are copper and the expanding ice can easily burst the pipe. So even after the pipe is thawed out you have a big job ahead since you now need to repair your plumbing. Viktor from Karosium has come up with a cost effective solution to dealing
Daniel Eindhoven has designed an interesting new Tesla Coil, this Double Resonance Solid State TeslaCoil has a new coil design which has the capacitor bank integrated into the primary coil. The new coil configuration has been dubbed the Eindhoven Primary. “A new composition of the primary coil for a Double Resonance Solid State TeslaCoil (DRSSTC). It is a combination of wire and capacitors. By making the coil like this you
I have never seen a project made with a Diffraction Grating before, but this LEGO Diffraction Grating Projector project has a great looking effect. It’s designed by Carl who was featured here before for his RGV Laser System. Those LEGO universal joints have a very wide working angle (watch the video to see what I am talking about). Thanks for sending it in Carl.
Victor Youk from Razor Concepts has designed a nice DTMF Decoder Board Project. The project is based around the MT8870 DTMF Decoder chip. With this project you will be able to control something from around the block or around the world using a simple telephone. Nice feature of using the MT8870 is you don’t need to program anything, just purchase all the components, stuff them onto a breadboard and have
Here is a DIY Digital Light Dimmer that uses 2 push buttons to adjust the brightness output. Full details can be found here. Thanks “The light level can be adjusted with two push-buttons “Up” and “Down”. Controller in this application is PIC16F84 that drives BUZ11 mosfet. Dimmer is tested with a light bulb 12V/4W and mosftet didn’t get even warm (which was expected since the datasheet says: 50V/30A).”
Long time Hacked Gadgets reader NatureTM has just completed phase 1 of his Hard Drive Clock. It’s using an Arduino to keep track of time and control the clock display LEDs. After accidentally letting out the magic smoke from the hard drive controller he decided to improvise and use a hobby RC motor speed controller. This clock will be super accurate when it is complete since it will eventually be
