RC Airboat Rescue

at 11:55 am. Filed under Cool Gadgets

 

TraxxAlu has a nice RC Airboat and Truck.  Watch this cool video where the RC Airboat gets stranded and needs to be rescued. Best of all it is all done remotely using FPV. I can see this working full scale quite well also!

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.”

Solder Paste Dispenser

Solder Paste Dispenser

 

There are lots of expensive Solder Paste Dispenser options but there will come a time that you just need to do more than is practical to do with a syringe and your fingers. That is when building a quick and dirty machine would come in. Good thing there is a system that you can model your endeavors after. The tricorderproject.org has a nice and simple DIY Solder Paste Dispenser project that might be just what you are looking for.

 

“The prototype that I put together is more of a sketch in hardware to help me appreciate the issues of paste extrusion, and help hammer out a design. Instead of using a plunger, I’ve used a very long lead screw that acts as the plunger, and has a gear atop with a captive nut to transfer force. The gear is driven by a Parallax continuous rotation servo, which I thought I’d try given that it simplifies the design by having an integrated gear box (which gives it lots of torque), and it can be directly driven by a microcontroller rather than requiring a separate stepper driver.”

Raspberry Pi Weather Station

 

Yes you can purchase weather stations that are ready to go but where is the fun in that? The Raspberry Pi Weather Station is designed for people who like to take control of their technology. 

 “WeatherPi is a solar powered Raspberry Pi WiFi connected weather station designed for Makers by SwitchDoc Labs. This is a great system to build and tinker with. All of it is modifiable and all source code is included. The most important functions are:

  • Senses 20 different environmental values
  • Completely Solar Powered
  • Has a full database containing history of the environment (MySQL)
  • Monitors and reports lots of data on the solar powered system – great for education!
  • Self contained and monitored for brownouts and power issues
  • Can be modified remotely
  • Download your data to crunch it on your PC
  • Can be modified to do SMS (Text) messaging, Twitters, webpages and more
  • Has an iPad Based Control Panel”
