Fly Swatter Compact Fluorescent Light Hack


If you have one of those electronic fly swatters kicking around you might want to hack it into a cool looking light. Steven from RimStar has just completed his Fly Swatter Compact Fluorescent Light Hack. The fly swatter is powered from 3 volts (2 AA batteries). The circuit produces a high voltage that electrifies a grid which the fly will short out through his body. The grid is removed and the circuit is modified slightly to optimize it for use with a CFL bulb.

HackRF on Sky Loop Antenna

at 10:53 pm. Filed under Cool Gadgets


Todd Harrison shows us how he is using his HackRF. If you have a ham license and want to work on a new RF project you might want to pick up a HackRF and do some experimentation. Using some mig welding wire Todd builds a 20M band antenna.

“In this video I put up a 20 meter band Delta Sky Loop Antenna with lighting arrestor to use with my HackRF One software defined radio.

I then demonstrate good reception from all over the USA as far away as 1500 miles using SDR Console software version 2 by SDR-Radio”

Robot Cake Decorating

at 7:49 pm. Filed under Cool Gadgets


Next time you see a nice cake at the bakery that looks to be custom made you might be fooled. Many of the new Cake Decorating Robots perform such a good job you would never know they were mass produced. The interface is nice since they user can simply free hand draw the design to be replicated, the robots then go to town and start pushing them off the end of the conveyor belt.

Whiteboard Erasing Robot


When you have a whiteboard all is good until you need to erase it.  This Whiteboard Erasing Robot will make quick work of it.

“The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text.”

DIY Water Level Sensor Build

DIY Water Level Sensor Build


Bob Johnson completed his DIY Water Level Sensor project. It can sense 4 levels of water, the results are transmitted using some Xbee devices. 

“The distance from my barn to the house is over 700ft. I used a 2.4Ghz yagi to send the signal to the house. This works great and no outside antenna is required at the receiving end. I have tried this setup at much smaller distances, and no yagi or directional antenna was required.

This setup has worked well for me. I use it to monitor my horses water trough. By eliminating the need for a micro-controller on the transmitting end and placing the Xbee in sleep mode, I have been able to run this setup for 10 months now on the same 3 AA batteries with the Xbee set in high power mode. “

Lost Signal RC Alarm & Lost Plane Finder

Lost Signal RC Alarm & Lost Plane Finder


When your RC plane flies  out of transmitter range some of them are setup to start a slow bank so that it hopefully flies closer to you and you can reacquire communication. What if that fails and the plane comes crashing back to earth? This Lost Signal RC Alarm & Lost Plane Finder project will help you in this case. When your transmitter is not connected the buzzer will sound so you can find it a bit easier. Construction is a nice and compact point to point solder construction which means no PCB is needed.

Valentines Day Slot Machine

Valentines Day Slot Machine 


If you want your valentine to work for their candy hearts why not build them a slot machine to let them win them. I have seen little bits before but this is the most complex device I have seen built!

“Try your luck with the littleBits Slot Machine and win a handful of candy hearts for your special someone. This slot machine operates just like the real thing. Pull the lever to start the graphics spinning on three DC motors. As they stop spinning in succession, win big when three hearts line up. When the hearts align, so do three bright LEDs and three corresponding light triggers. This signals the servo-activated trapdoor to release a candy jackpot.”
