2.4GHz Waveguide Cantenna with Circular Polarization

at 5:38 pm. Filed under Complex Hacks


If you need to shoot your WIFI further than your regular WIFI can reach you can look into building this 2.4GHz Waveguide Cantenna with Circular Polarization to give you a boost in range.
“I decided to use a cloverleaf antenna as the driven element with a toilet brush holder as the waveguide. It must be noted that the waveguide in this version is not physically connected to the driven element as doing so will affect the VSWR. As I show in testing this is a powerful waveguide when used with a matched antenna with circular polarization and although powerful it is extremely directional with a beam width of 30 degrees.”

Electric Mobility Scooter Hacked for More Speed

at 11:57 pm. Filed under Crazy Hacks


When pumping 60 volts into this Electric Mobility Scooter it turns into tons of fun. Their is no soft start on this thing so as soon as the launch button is pressed the motor springs to life. Interestingly enough this scooter has some drag bars that prevent the thing from flipping over backwards. Not sure how long the motor would last with this voltage but it sure looks like fun while it lasts. They even tested it with a few runs at 72 volts! Doesn’t take long to get up to speed with that voltage. The electronics were slightly modified, a nice large contactor was added to allow a small horn button to control the large load. In the end 72 volts was more than the motor could take and it burnt up.

Car Horn Alarm Clock

at 12:10 pm. Filed under DIY Hacks, Electronic Hacks


This Car Horn Alarm Clock is sure to wake you up in the morning. Not sure if the volume would beat my Fire Alarm Bell Alarm Clock but either is sure to get the job done. The clock in this hack has a nice small motor that is activated to ring the alarm on the stock unit. A small transistor is used to drive a mosfet to handle the large current needed for the car horn.

If you are looking for the latest in personal mobility have a look at the Omni Hoverboard. At first I was thinking this video was faked, but in fact this board is real and has recently won a Guinness World Record. Looks very tricky to fly around and as we can see the trials are being done over water for safety. I would have thought plunging into water would not be good for the motors, I wonder if after a plunge much of the parts need to be replaced?

Via: International Business Times

“The Omni Hoverboard features eight propellers and a frame made from carbon fibre. The motors controlling the propellers are powered by 12 lithium polymer batteries, which generate around 40 horsepower, but sadly, this currently generates a combined flying time of only 1.5 minutes.

Acceleration is achieved by squeezing a joystick made from a pair of pliers which makes the hoverboard go higher or lower, and speed up or slow down. The user is securely anchored to the hoverboard using snowboard binding straps, steering the board by physically turning in the air to change its direction.”

Hand Cranked High Voltage Ball Spinner

at 4:30 pm. Filed under DIY Hacks

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 the next. There are a the project is simple and can probably be built with items you have in the house. The video below shows how to build the power source for the system, it is a Wimshurst Machine which will provide the high voltage needed to power the system. The power supply can also be made with stuff that you probably have at hand also.

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.”

JIGMOD Electronic Circuit Building System

at 7:16 pm. Filed under Electronic Hacks



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 does JIGMOD do it?

  • JIGMODs and the mounting configuration allows for stacking JIGMODs of the same size, revolutionizing the prototyping process
  • Wire-to-board connectors – make wire connections with the push of a finger! No screwdrivers are necessary for this operation.
  • Pre-tapped drill holes in platforms allow versatile mounting configurations
  • Board-edge fasteners – allows 2 boards to utilize the same supports and increases parts per area.
  • High quality JIGMOD modules with high quality electronic components”
