Z6 Riot Control Baton

at 7:12 pm. Filed under Cool Gadgets

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.

Flaming Lightsaber

at 3:19 pm. Filed under Complex Hacks, Cool Gadgets



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.

11kV Lightning Arrester

at 4:53 am. Filed under Cool Gadgets, Teardown



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 of MOV’s conduct the voltage to ground.

“This is a lightning arrester from an 11kV power distribution line with an interesting feature to clear itself electrically when sustained current flows through it.
Inside a robust fibreglass insulated core is a stack of MOV’s (Metal Oxide Varistors) which have a combined voltage to handle the regular peak voltage of the 11kV supply (presumably 15.5kV peak) plus a safety margin. However, when a higher voltage transient occurs on the line the MOV voltage is exceeded and they temporarily develop a lower resistance which shunts the transient to ground to protect other components on the line.
If an excessive over-voltage occurs or the MOVs start to break down after passing a modest amount of transients then there is a disconnecter attached to the bottom of the unit that will literally detonate and blow the ground cable off the end of the unit for safety. The primary function of this is to prevent the lightning arrester from passing significant current from the normal 11kV supply when it fails.”

Name the Thing Contest – 290

at 11:37 pm. Filed under Contests



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 the answer in the comments.

Send an email to contest @ hackedgadgets.com with “Name the Thing Contest” as the subject, and the message body consisting of:

  • The name of the item in the above picture
  • An example of what the item pictured above can be used for

The winner will be chosen at random from all of the correct entries.

Below is a picture of the prize.

IR Shooting Game Project – Laser Duel

at 11:10 pm. Filed under Educational, Electronic Hacks, Game Hacks


Laser Duel is a project made by XiaoXing Zhao, Fred Kummer and Douglas Katz for their ECE 4760  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 things such game over.

“Each gun has an infrared emitter for shooting and an infrared detector that detects if the player using the gun was shot. We designed the shooting mechanism such that when the player presses a trigger on the gun a 38 kHz infrared wave will be emitted. If such IR radiation is detected by another gun, then the shot registers as a hit and the player being hit will lose one point of health. Each player starts off with 8 health and the game will end once a player reaches 0 lives, or if someone operating the basestation signals to end the game early. We equipped the guns with a ultra low power radio that sends vital statistics about the player such as player health and player identification to the base station.”

Magnetic Stripe Spoofer – MagSpoof

at 12:49 am. Filed under Complex Hacks


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 normal magnetic stripe as if it’s being swiped. What’s incredible is that the magstripe reader requires no form of wireless receiver, NFC, or RFID — MagSpoof works wirelessly, even with standard magstripe readers. The stronger the electromagnet, the further away you can use it (a few inches in its current iteration).”

The Illustrated Arduino


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 if you are just interested in using some of the material for some learning and experimenting the digital version of the guide if free!

Thanks for the tip Julia.

“16Hertz, an educational electronics company based in New York City announces the release of their illustrated, graphic-novel style guide, “The Illustrated Arduino”. The guide is over 75 pages long, and contains hundreds of hand-drawn illustrations that take the readers through getting up-and-running with electronics prototyping and Arduino programming.”
