Electrostatic Motors are Making a Comeback
Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back. [via MSN/WSJ] While the first …read more Continue reading Electrostatic Motors are Making a Comeback
‘Upgrading’ a Microwave Oven To 20 kW
Whilst microwave plasmas are nothing new around here, we were curious to see what happens at 20x the power, and since YouTuber [Styropyro] had put out a new video, we …read more Continue reading ‘Upgrading’ a Microwave Oven To 20 kW
Pushing the Plasma Limits With a Custom Flyback Transformer
For serious high-voltage plasma, you need a serious transformer. [Jay Bowles] from Plasma Channel is taking his projects to the next level, so he built a beefy 6000:1 flyback transformer. …read more Continue reading Pushing the Plasma Limits With a Custom Flyback Transformer
A Field Guide to the North American Substation
Drive along nearly any major road in the United States and it won’t be long before you see evidence of the electrical grid. Whether it’s wooden poles strung along the …read more Continue reading A Field Guide to the North American Substation
Retrotechtacular: Powerline Sagging and Stringing in the 1950s
While high-voltage transmission lines are probably the most visible components of the electrical grid, they’re certainly among the least appreciated. They go largely unnoticed by the general public — quick, …read more Continue reading Retrotechtacular: Powerline Sagging and Stringing in the 1950s
Cheap Musical Tesla Coil Put Through Its Paces
Once upon a time, musical Tesla coils were something you primarily saw at high-voltage hobby meets. They’ve become more popular in recent years, and now you can even buy cheap …read more Continue reading Cheap Musical Tesla Coil Put Through Its Paces
Who’s Afraid Of A CRT?
Older consumer electronic devices follow a desirability curve in which after they fall from favour they can’t be given away. But as they become rarer, they reach a point at …read more Continue reading Who’s Afraid Of A CRT?
Electrospinning Artificial Heart Valves
When you think about additive manufacturing, thoughts naturally turn to that hot-glue squirting CNC machine sitting on your bench and squeezing whatever plastic doodad you need. But 3D printing isn’t …read more Continue reading Electrospinning Artificial Heart Valves
High-Voltage Fun with an Inexpensive Power Supply
It used to be that nearly every home had at least one decent high-voltage power supply. Of course, it was dedicated to accelerating electrons and slamming them into phosphors so …read more Continue reading High-Voltage Fun with an Inexpensive Power Supply
