Hacking Fake Food
Ever seen a restaurant where they display fake models of the food on the menu? We never thought much about how shokuhin sampuru — the Japanese name — were made until …read more Continue reading Hacking Fake Food

Piezo Pickup Makes Wax Records Easy to Digitize
Sound recording and playback have come a long way in the last century or so, but it’s fair to say there’s still a lot of interesting stuff locked away on …read more Continue reading Piezo Pickup Makes Wax Records Easy to Digitize
Reviving Old Recipe for Faraday Wax Keeps Vacuum Experiments Going
Science today seems to be dominated by big budgets and exotics supplies and materials, the likes of which the home gamer has trouble procuring. But back in the day, science …read more Continue reading Reviving Old Recipe for Faraday Wax Keeps Vacuum Experiments Going
Homemade Capacitors Of A Mad Scientist
Once upon a time I was a real mad scientist. I was into non-conventional propulsion with the idea of somehow interacting with the quantum vacuum fluctuations, the zero point energy field. I was into it despite having only a vague understanding of what that was and without regard for how unlikely or impossible anyone said it was to interact with on a macro scale. But we all had to come from somewhere, and that was my introduction to the world of high voltages and homemade capacitors.
And along the way I made some pretty interesting, or different, capacitors which I’ll …read more
Metal Casting With Single Shelled PLA Masters
[3DTOPO] does a lot of metal casting (video link, embedded below). That’s obvious by the full and appropriate set of safety gear, a rarity on YouTube.
They had all the equipment to do it the normal way: craft or CNC out a master, produce a drag and a copy, make any necessary cores, and finally; pour the mold. This is a long and tedious process. It has a high rate of error, and there is a parting line.
Another set of methods are the lost ones. With these methods the master is produced out of a material like foam or wax. The …read more

Wrangling High Voltage
Working with high voltage is like working with high pressure plumbing. You can spring a leak in your plumbing, and of course you fix it. And now that you’ve fixed that leak, you’re able to increase the pressure still more, and sometimes another leak occurs. I’ve had these same experiences but with high voltage wiring. At a high enough voltage, around 30kV or higher, the leak manifests itself as a hissing sound and a corona that appears as a bluish glow of excited ions spraying from the leak. Try to dial up the voltage and the hiss turns into a …read more
