If you enjoy table tennis this trainer might be a great next project. Thomas Mayer created this as his bachelor thesis project. Two Playstation CL-eye cameras are used to view the play area and track the ball. A project is then used to display game elements that the players can interact with to play many game scenarios. The game was created using VVVV which is a visual/textual live-programming environment for easy prototyping and development.

“The basic idea of my bachelor thesis was to track the ping pong ball in realtime to create data visualisations for trainers and players. After a few weeks of working I started developing a projected mapped interface for the ping pong table to show the collected data. By projecting game obstacles on the surface I figured out that I can change the game play totally.”

Mechanical Television Build

at 2:56 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


 
 
Ben Heck and his team built this Mechanical Television. It uses holes drilled into a vinyl record which is spun with a light source behind it. A light sensor is then used to determine the amount of light that is reflected off the surface of the item that they would like to transmit. A complimentary rotating disk with a controlled light source is used to duplicate what the first system is seeing. The build didn’t quite work in the end but the techniques and information that we see along the way is worth it.

 

 


DIY Volume Control Builds

If you are tired of reaching for your tiny volume control knob to adjust your music when using your computer look no further than these projects by Engineering Nonsense and DIY Perks. The top one uses a DIGISpark board and a rotary encoder to adjust the volume via USB and the one below uses a potentiometer to adjust the analog output of your signal feeding your amplifier.

LiPo Battery Danger

at 11:04 pm. Filed under Electronic Hacks

 

LiPo batteries are used everywhere. You might think twice before you toss them around like the regular alkaline batteries that are much safer and very common. GreatScott shows us how accurate the built in protection circuits are. You probably won’t be surprised to learn that they are not very accurate and often take much more current than expected to trip.

Largest Plasma Arc Vortex Speaker

Have a look at this interesting Plasma Arc Vortex Speaker. Unlike the regular plasma ark speakers that you have seen in the past.

Via: Hackaday
“After replacing the power supply and adding an RC snubber across the flyback transformer primary, my plasma speaker is already much louder. The addition of a more powerful PSU, it allowed me to also reduce the number of turns on the primary, which increased the voltage output. The RC snubber not only protects the MOSFET from the inductive spike of the flyback transformer, but it also drastically reduces the ringing associated with the capacitance between the MOSFET drain and source and the leakage inductance of the flyback transformer. The music your hear is only from the arc and nothing else. There are no other sources of music in the room. It works by using a 555 timer to convert an audio input signal into a frequency modulated signal used to drive a flyback transformer.”

Soldering Reflow Oven

 

Here is a project to get your SMD projects built with ease.

Via: Electronics Lab

“This particular instructable is based on the ControLeo2 reflow oven controller by Peter Easton. This is by far the best I’ve come across and the software is fully open source. It can control up to 4 solid state relays (SSRs), a servo motor (to open the door for cooling at the end of reflow process) and a buzzer. Most impressive is that it is self-learning. That means, it can adapt to your oven heating elements and their behavior. ”

Apple Recycling Robot

at 2:54 pm. Filed under Cool Gadgets, Crazy Hacks, Electronic Hacks

 

Apple produces a lot of electronics, unlike a pop can something like an iPhone is not the easiest thing to melt down and turn into something new. Apple wants to go green by allowing the recycling of your devices when you are done with them.

“Introduced onstage in a peppy video, “Liam” the robot — more specifically a robotic arm — was specifically developed by Apple engineers to pick apart iPhone and other gadgets, tearing the devices down into discreet modules. These parts, like an iPhone screen or logic board, can then be broken down further to recover materials for reintroduction into the global supply. ”
