The use of magnetic tape and other removable magnetic media is now on the wane, leading to scarcity in some cases where manufacture has ceased. Is it possible to produce …read more Continue reading Making Magnetic Tape From Scratch
There are plenty of chemical processes that happen commonly around the house that, if we’re really following safety protocols to the letter, should be done in a fume hood. Most …read more Continue reading Custom Fume Hood for Safe Electroless Plating
If film photography’s your thing, the chances are you may have developed a roll or two yourself, and if you’ve read around on the subject it’s likely you’ll have read …read more Continue reading Spuds Lend a Hand In The Darkroom
The regular refrain here when it comes to announcements of new battery chemistries hailed as potentially miraculous is that if we had a pound, dollar, or Euro for each one …read more Continue reading Rock Salt May Lead The Way To Better Batteries
Building circuits on a silicon chip is a bit like a game of Tetris — you have to lay down layer after layer of different materials while lining up holes …read more Continue reading Testing Oxide Etchants for the Home Semiconductor Fab
Although the basic concept of electrostatic attraction has been known since ancient times, it was only in the 17th century that scientists began to systematically investigate electrostatics. One of the …read more Continue reading Electrostatic Generator Project Starts With Molten Sulfur
There’s a simple reason why high-tech gadgets like PCs, TVs and smartphones are so cheap: they’re mass-produced. By spreading out huge engineering costs over equally huge production volumes, the cost …read more Continue reading Homebrew Probe Tip Etcher Makes Amazingly Sharp Needles
