CALEB KRAFT from Make shows us the Z6 Riot Control Baton that he built. The build cost would be low since most of the construction is out of PVC piping. The result is a great looking weapon. It has actually been enhanced with a bit of high voltage danger for some extra fun. An internal spring allows the unit to spring into action.
Allen Pan built this great looking Flaming Lightsaber. He got the inspiration from Tesla Down Under. By igniting some spraying methylated spirit the effect is a great looking flame.
Bigclivedotcom takes a look at how a 11kV Lightning Arrester works. When high voltage lines take a lightening hit they attempt to short it to ground to prevent passing the huge spike in voltage on down the line. The technique used is similar to what is done in a power bar on a big scale. When a high enough voltage is present in the line side a stack
The prize this week is a relay module that would allow you to use a small signal from your microcontroller to control some high power items like heaters and large motors. This contest will run for one week (December 13 – December 18, 2015). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give
Laser Duel is a project made by XiaoXing Zhao, Fred Kummer and Douglas Katz for their ECE 4760Â Final Project. The two guns use Nordic nRF24L01 radio transceivers to talk back to a base station which monitors the game play and keeps score. Each gun has some visual indications so the players can see what the health is and there is also a speaker for some audible indications for
We have seen this type of device before but Samy has done a great job making his tiny version. We have also seen some interesting alternative methods of reading the magnetic card information, the reading method is amazing that it can be read by the naked eye. “MagSpoof emulates a magnetic stripe by quickly changing the polarization of an electromagnet, producing a magnetic field similar to that of a
If you know someone who is interested in trying Arduino for the first time this is a great looking friendly guide by 16Hz that will walk them through everything from how a microcontroller can read a switch to how the microcontroller can use PWM to output a simulated analog output. There is a hard copy version of the guide available, there are lots of kits and parts available but
