If you’ve ever wondered what lies beneath the barely visible hole in the can of a MEMS microphone, you’re in luck, because [Zach Tong] has a $10 pair of earbuds …read more Continue reading Up Close and Personal with a MEMS Microphone
We’ve been eagerly following [ProjectsInFlight]’s stepwise journey toward DIY semiconductors, including all the ups and downs, false leads, and tedious optimizations needed to make it possible for the average hacker …read more Continue reading Simple Chemistry to Metallize and Etch Silicon Chips
You may know William Blake as a poet, or even as #38 in the BBC’s 2002 poll of the 100 Greatest Britons. But did you know that Blake was also …read more Continue reading William Blake Was Etching Copper in 1790
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
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
For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you …read more Continue reading Copper Be Gone: The Chemistry Behind PCB Etching
[Sebastian] probably didn’t think he was wading into controversial waters when he posted on his experimental method for etching PCBs (in German). It’s not like etching with hydrochloric acid and …read more Continue reading Different Etching Strokes for Different PCBs, Folks
Easy PCB fabrication in China has revolutionised electronic construction at our level, but there are still times when it makes sense to etch your own boards. It’s a messy business …read more Continue reading Shake Your PCB Etching, With An Old Optical Drive
[Applied Science] wanted to make some metal parts with a lot of holes. A service provider charged high tooling costs, so he decided to create his own parts using photochemical …read more Continue reading Better Sheet Metal Parts with Chemistry
Brass plaques are eye-catching because no one makes them on a whim. They are more costly than wood or plastic, and processing them is proportionally difficult. [Becky Stern] picked the …read more Continue reading Brass Plaque Honors Brother
