Automated Table Tennis Score Keeper

 Automated Table Tennis Score Keeper


Playing Table Tennis is fun but some automation can make it a bit more fun. Taylor Pritchard, Pol Rosello and Frank Xie just completed this Automated Table Tennis Score Keeper for their ECE 5760 Final Project. The project uses a Altera DE2-115 FPGA to monitor for the ball color to watch the game play and score accordingly.

“We use a Sony Handycam DCR-DVD108 as the camcorder to monitor the table tennis game. The NTSC video feed of the camera was used as an input to the DE2-115, where it was split into YCbCr components to isolate the green content of each frame. The luma component of each frame (Y) was not taken into account in order to allow for flexibility in the lighting of each frame. Thresholds for the blue and red component (Cb and Cr, respectively) were determined experimentally to match the color of the green balls. In order to reduce the influence of noise from other green objects in the room, we spray painted the balls a neon green color to ensure the color of the balls was distinct, much like green screen technology used in film and television.”

Raspberry Pi Minecraft Blocks with NFC

at 4:47 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Game Hacks


If you are into minecraft you will soon be able to use some technology to interact with the game using physical objects. Adafruit is making this possible with an NFC reader that they will be releasing soon.


“Coming soon to the Adafruit Learning System, a project to make paper Minecraft blocks that interact with the game on a Raspberry Pi using NFC (near field communication)! Swiping a block on the Adafruit PN532 NFC reader causes it to be created in a Minecraft world running on a Raspberry Pi.”

Video Game Repairs

at 5:31 pm. Filed under Cool Gadgets, Game Hacks


Video game play used to be an activity that was played in an arcade with a pocket full of quarters. There is still a huge following for these classic games. Thanks to the repair work that guys like arcadeuk do they will be kept running for years to come. It is interesting to see that there are lots of mods that improve things like the need for battery backups etc. I am glad that there isn’t the same nostalgia keeping 286 computers running!

Sega Cartridges Resurrected using some old Computer Chips

Sega Cartridges Resurrected using some old Computer Chips


Dragao has a Sonic Cartridge that had some invalid instructions that would cause the game to crash at a certain point. The solution wasn’t to find a replacement game at the local flea market, he Resurrected the Sega Cartridges using some old Computer Chips. The game was originally loaded on 16 bit memory chips, not having any of these handy from the donor computer motherboards he piggy backed 2  8 bit memory chips to make it work. An Arduino was then used to blast the code onto the new chips.

Classic NES played using a Kinect

at 7:53 am. Filed under Game Hacks



Tired of using a pesky remote control to play your video games? Paul DeCarlo used a Kinect sensor and some other bits and pieces to allow you to interface with some old video games!


  • An NES console with game to test
  • An NES controller OR some wiring skills and a CD4021BE 8-bit shift register
  • 12 strands of wire, recommend Kynar
  • 8 1k resistors (technically any value from 1k to 50k should suffice)
  • 2 3.6k resistors (again higher not necessarily bad)
  • IoT board capable of running Firmata, Intel Galileo or Arudio Uno etc.
  • Kinect V2 Sensor for Windows OR recently announced Kinect V2 Adapter and existing Xbox One Kinect Sensor
  • Machine capable of running the Kinect V2 SDK

  Double Useless Machine_2


So we have all seen a useless machine before and what could be more fun that one of those? How about a Double Useless Machine, this is the machine for us who might be a bit too lazy to interact with the machine. With this design you simply need to take the switch off the center mode and watch the machine in action.

Bitcoin-Operated Pool Table

at 10:43 pm. Filed under Game Hacks


Stuart Kerr sent in some details about their Bitcoin-Operated Pool Table. With Bitcoin getting more traction as time goes on I think we will start to see more systems like this game that will accept bitcoin as an option.

“Basically we’ve made a pool table where payment can be made by Bitcoin instead of (well actually as well as) cash! It works pretty well, with a Raspberry Pi controlling the whole thing, and a Bitcoin QR code + LCD screen on the side for payments to be made. We’ve got a video showing it in action, with the pool balls being released just moments after the payment is sent from a mobile phone.”
