Like making circuit boards, but don’t like all of the toxic chemicals that you have to use to do it? You might want to take a look at Stephen Hobley’s directions, then. He’s claiming to be able to etch boards using only diluted hydrogen peroxide, vinegar, and a bit of table salt. He’s got an […]
Hosting a wine tasting party is as simple as inviting your favorite friends over for a drink! It’s the perfect way to have a low-key, fun event and it is also an opportunity to become more educated. Start by selecting a grape varietal. Limiting the tasting to a single type of wine will help you […]
Anna at Mochimochi Land has a new cross-stitch pattern called When Tessellations Roamed the Earth. Perfectly geeky right? If you’re looking to learn cross-stitch, Anna has a handy cross-stitch basics tutorial on her site too.

One of my favorite times of the day is when I slide in to bed and grab my book and start reading. I have an almost impossible time going to sleep if I don’t have a book to read beforehand. These little bowtie paperclip bookmarks from Jessica of How About Orange seem about the most […]
Most of our readers will know that one of the most common types of residential smoke detectors actually contains radioactive material—specifically, an isotope of americium—which is used to ionize air molecules in the detector itself. In this video, the always-engaging Bill Hammack, aka Engineer Guy, explains both the operation of the ionizing detector and, most interestingly for me, also the circuit in which it operates, and the MOSFET which is the other critical component in that circuit (and is, incidentally, the namesake of Phil Torrone’s cat). Characteristic Bill quote: “To me, this is engineering at its best: Simple, reliable, and inexpensive. And saving countless lives.” Thanks, Bill, as always!
Quinn Dunkimade this “beating heart” LED pendant using the “Pulsing Glow” circuit experiment from the Make: Electronics book.
