My "they don't make 'em like they used to" lick recently backfired when I cut my finger pretty badly on the metal blades of an antique fan I was restoring. So I tried replacing the metal blades with heavy leather, for safety, which actually ended up looking and working great. 
When my cheap plastic box fan recently self-destructed, I “retrograded” to this lovely model 94646-E “Northwind” oscillating electric fan by Emerson Electric. Within ten minutes of turning it on fo...

Lazyweb question: Say I want to hire a contract photographer in a distant city for a day or weekend gig in that city. I will likely want to do this regularly, in cities all over the country and possibly the world. Where do I find such folks? Anybody have any experiences with smartshoot.com?

An ambitious BEAM-style project I developed but never published for MAKE's old Make: Projects platform. Good-looking but too complicated for most builders; there's a PDF available for curious clickers-through.
This is a Herbie-style BEAM photovore with a reversing relay. But instead of a bump switch, the “retreat” reflex is triggered by a sharp, loud sound like a clap. It was developed for MAKE’s RadioSh...

“Additive Synthesis of a Square Wave,” 2013. I prepared this illustration to accompany Jon Thompson’s Arduino sound synthesis article from MAKE Vol 35. It was published as Figure K. It shows how a more complex waveform (a square wave, in blue) can be synthesized as a sum of sine waves. The black wave is the fundamental, which has the same frequency as the synthesized wave, and the gray-valued waves are the various odd harmonics up to the 15th; lighter-valued waves are more attenuated and contribute less to the synthesized curve.

I used Google Sheets to compute the values of the various sine waves at 1,000 positions along one cycle, multiplied them by their attenuation factors, and added the results together at each point to produce the synthesized wave. Then I plotted the waves, right-clicked on the plot in my browser, and manually copy-pasted the SVG text of the curves from the raw HTML into a text editor. Then I saved the text file with a .SVG extension and imported it into Illustrator to tweak the colors and add the labels. A handy trick if you ever need to generate vector art from plotted data.

The ridiculous saga of getting my (otherwise awesome) new Seek thermal imager to point the right direction: 
Possibly the best gift I received in 2014 was this Seek thermal add-on imager for my phone. Unfortunately, the device comes with a non-reversible micro-USB plug attached, and the single jack on my ...

This old lighthouse Fresnel lens assembly is one of the most beautiful man-made objects I have ever seen. If you ever find yourself near The Argonaut hotel in Fisherman's Wharf, don't miss the chance to see it.

also, if you have time for a daytrip, the Point Reyes lighthouse (north of sf) does summertime tours inside the lighthouse - http://www.nps.gov/pore/planyourvisit/rangerprograms.htm#CP_JUMP_388238

Not only did I get my first Popular Science byline in the March 2015 issue, I also got a coverline! =D

They don't make 'em like they used to.  This is a Crabtree model A15051 single-gang AC light switch, with cast iron body, that I recently scored on eBay. It was likely manufactured in the 30s, 40s, or 50s, and restored by the eBay seller. I wired it as a remote switch for my photo soft box.  Thing's built like a tank, beautiful to look at, feels great to the touch, and operates with a satisfying CLACK.  #retro #antique #electrical #brittania

If you're an entitled yuppie with a pupa in tow, please go elsewhere. This place was not made for you, you will have a lousy time, and your presence will ruin it for the intended audience. Fanks.
