Bruce in a Box Augmented Reality Project - Cornell University ECE 5760


Julie Wang developed the Bruce in a Box Augmented Reality Project for her ECE 5760 final project. This looks like a fun project, to see where the name comes from watch the video at 3:00.

“My system makes use of a variety of digital signal processing and computer vision techniques, resulting in a robust and reliable system. The hardware I utilized was the DE2-115 board by Altera, a Video Camera, and a VGA monitor. All of the functionality of my project is achieved through custom hardware written in Verilog. There are an extensive number of modules, and each one is designed to be as modular and parameterizable as possible.”

Wall Mounted Computer Chess Board Project



If you like playing chess this Wall Mounted Computer Chess Board Project might be something that would be a good project to add to the list. It has a vintage chess game hacked into this hand made wall hung chess board.

Thanks to Artless Dodger for sending this in.

“Parts Needed

Working Fidelity Chess challenger 8 or 9
Power adapter 8v
Coin cell battry 3v
MDF 6mm board 410 by 710
Brown or black leather half square meter
White or cream leather half square meter
Cable straps (Thin)
Acrylic glass 10 * 400L *30mm Deep * 6MM thick (2 spare)
Leds , 3Vm blue and red,
30 cms fibre optic wire ,(you only need about 10 inches.) side glow or end glow is fine.
Kynar single core 30awg transfer wire,or equivalent 30awg stranded wire. various colours
Momentary push buttons (8mm pole)
Function Buttons (built in 3v Led blue)
KIT circuit
All purpose adhesive
Sheet plastic , thinner than credit card, thicker than paper, (think phone screen protector)
Wooden frame with interior opening 400 *700 and with a 5mm underlap. If you can only get 8mm underlap you’ll need to adjust size of the board”

eBay Photoswitch Teardown

at 9:21 am. Filed under Electronic Hacks



I spotted this photoswitch on eBay and had to take a look at the guts (search photoswitch if the link doesn’t work since eBay links go stale after a short time). I now see that the same unit is sold in multiple variations which are 24V and 220V. Not sure I would feel safe with 220 on this thing though. I am curious if the 10 ohm resistor is the only difference between the versions. If someone has one of the other versions leave a comment to let us know what the difference is. These are selling for $3.39 which included free shipping from China to Canada! Hard to believe how tilted the scales are here, I wouldn’t be able to ship this within my city for $3.39. The unit is powered from 12 volts AC or DC, it also switches the same power to the third output wire when activated. The circuit is using a 555 for operation. When the photocell goes from light to complete darkness the relay activates in 3 or 4 seconds. You can view full resolution images here.

DIY Boombox

at 11:39 pm. Filed under DIY Hacks, Electronic Hacks


David Watts has made a DIY Boombox which is made with mostly off the shelf pieces that have been hacked together. Some of the features the boombox has is line in, bluetooth input, radio, spectrum analizer and a partially working pong game. An Arduino is built into the box to do some of the control. The box is powered from a 6 AA cell battery pack, a step down converter is used to create a nice 5 volt output.

License Plate Electric Guitar

at 6:09 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks


Mike Senese from Make shows us how to make a License Plate Electric Guitar. Some basic tools are used to create a totally custom electric guitar, the video shows you how to wind the pickup coil using some screws, plywood and magnet wire. When this project is done you will have a guitar to jam on. In the example video a pre built guitar neck was used but depending on how elaborate you want this could also be hand made.

Optical Mouse Video Output Hack

at 2:19 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


The $5 mouse that you just tossed in the garbage might have had some hackable life still in it. As Conor Peterson shows us most optical mice are actually quite simply in operation with most of the hard work being done by the low resolution camera sensor. With a bit of Arduino code he was able to read out the serial image data directly from the mouse and display it on the monitor.

Re:Load Pro – Active DC Load

at 8:59 am. Filed under Electronic Hacks

 ReLoad Pro - Active DC Load 


The Re:Load Pro is an Active DC Load Kickstarter. It is almost at the goal so it looks like they will be made. If you have a need to load test power supplies and various other pieces of gear this might be just the thing for you. The price seems very good and the unit looks fantastic with that snazzy display.

 “The Re:load Pro’s features include:

  • Dissipate 25 watts continuously, or more for short periods. Even more with the forthcoming fan kit (see below!)
  • Handle up to 6 amps or 60 volts. Works right down to 0V, too!
  • Easy to use and intuitive user-interface.
  • Current adjustable with milliamp precision over the whole range.
  • Protection against overcurrent, overvoltage, overtemperature, ESD, and reverse polarity.
  • Power supplied over USB from either a computer or a USB charger.
  • Fully isolated USB interface. Your computer is isolated from any direct interaction with dangerous voltages and currents.
  • Fully controllable over USB, with monitoring functionality. You can use your computer to program in a profile!
  • Configurable display, showing voltage, current, power, resistance, and total energy dissipated.
  • Open Source, with a USB bootloader, so you don’t need expensive development tools if you want to make your own modifications. Firmware updates will be easy to install, too!”
