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
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
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
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
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
