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.”

High Speed Corn Starch Experiments

at 11:45 am. Filed under Crazy Hacks


We have seen lots of corn starch experiments in the past. When mixed with water it is a liquid that can be poured but if you shock it with a hard impact it will turn into a solid. There are lots of fun experiments that can be done with it but the TheBackyardScientist has recorded some great reactions with his high speed camera. The best reaction I think is the one at 2:50 where a golf ball is shot at a balloon filled with the liquid, in real time it looks like a normal explosion but in slow motion you can see that the substance breaks apart like chunks of fruit.

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.

Thermite Gun

at 9:25 pm. Filed under Crazy Hacks


We have seen some interesting uses for thermite before but colinfurze has taken thermite fun to the next level with his Thermite Gun build. You can see it in action above and the build process below. This build isn’t for the faint of heart and is probably illegal in your area so duplicate the system at your own risk!

Star Wars AT-ST Walker Build


Fans are great, check out this Star Wars AT-ST Walker Build!

“The AT-ST Walker was designed to be a recon, hit-and-run vehicle in the Star Wars universe, and is one of the series’ most iconic vehicles to say the least. What could be better than a few collectible toys? Having a full-scale replica in your backyard of course, and this one was made from scratch using a combination of timber, plastic, along with bits of scrap metal. ”
