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.

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.”

Cuba Wood Burning Engraver

at 7:30 pm. Filed under Cool Gadgets




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.

DIY Articulating LED Task Lamp

at 6:07 am. Filed under Cool Gadgets, DIY Hacks


This Articulating LED Task Lamp is full of features such as magnetically replaceable lighting heads. Everything from the LEDs to the panel clip style can be customized or simplified to match your needs.

“For the light part, I decided to use LED strips, because they‚Äôre so easy to use. Plus they‚Äôre powered with a remote and it‚Äôs always nice to be able to dim. So I cut up a bunch of Baltic Birch plywood for the arms, the connecting parts, and the panel for the lights. I also made some octagon knobs out of plywood which connected the arms together.”
