Laser Transmits Audio Over 100m

at 4:24 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

If you are looking to send some data or some audio over a fairly long distance wirelessly you can have a look at this very cheap solution if line of site will work. Iforce2d is using a very inexpensive laser diode and receiver to get the job done. This code is what does the heavy lifting as far as getting the data across the link.

5-Axis 3D Printer

at 10:06 pm. Filed under Cool Gadgets

 

 

Enomoto is developing a 5-Axis 3D Printer which will be for sale in about a year. This will change much in the 3D printing world since there were limitations that were imposed from the regular elevation printing style. Since the platform is able to move the printed piece in any angle very complex parts that were impossible before can now be built.

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.

Largest Plasma Arc Vortex Speaker

at 3:47 pm. Filed under Cool Gadgets, Electronic Hacks

 

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.”

There are hundreds of these booths that sell souvenirs in Varadero Cuba. They all have the capability of customizing the leather and wood crafts using Wood Burning Engravers. They all look the same, a box that plugs into 220V with a wooden hand held burning tool. There was a guy repairing one and let me snap some pictures. Inside is a modified MOT (microwave oven transformer) with just around 10 wraps for the secondary. The case appears to be recycled car battery case, the design is quite simple but very effective.
