A device made in under an hour ends up being an extremely handy test tool.

[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only took about an hour to make. The device ended up being a pretty…

legibility is very important, whether we are talking about source code or schematic diagrams. glad i'm not the only one who is very particular about this.

Spend the next couple of decades counting down to the UNIX epoch in style!

Admit it: when you first heard of the concept of the Unix Epoch, you sat down with a calculator to see when exactly 2³¹-1 seconds would be from midnight UTC on January 1, 1970. Personally, I did that math right around the time my company hired contractors…

Toyota Prius Hacked to Connect with San Francisco’s MUNI Power Lines
https://blog.adafruit.com/2018/09/20/toyota-prius-hacked-to-connect-with-san-franciscos-muni-power-lines/

If you’ve ever been to San Francisco then you know the look of the city’s Municipal Railway’s network of overhead cable lines (above). Sierra Hartman reports for the Bold Italic on “Jon” and his “MUNI PWR” license plated “Franken-car” that draws power from the city’s cable lines.

A couple months ago I was walking out of Golden Gate Park onto Fulton around 8th Avenue. I stepped onto the sidewalk just in time to see a Prius roll by with a pair of giant antennae mounted on the roof. At first I thought it was just some kind of art-car getup, but then I realized the antennae was the same power pole doodad that MUNI buses use (I later learned they’re called “trolley poles”). Not only that, they were actually running along the overhead power cables for the 5 line. The driver cruised past with a high-pitched humming noise as I stood there thinking, “No. Fucking. Way.”

Two weeks ago I was in the Safeway parking lot at 16th and Bryant when I saw the driver again. This time I was on my motorcycle and happened to have my camera. I snapped a few shots as he passed the bus stop, then jumped on my bike and followed him east on 16th. I caught up to him a few blocks later at Kansas. Before I even dropped into first gear I could hear Foghat blaring out the windows, “Sloow riide, take it easy…”

I pulled up behind him and noticed his fantastically appropriate license plate: MUNI PWR. I sidled up next to the open driver’s side window and shouted over the music, “Hey, man! Are you actually running on the power lines with that thing?”

“You know it, dude! 150 miles of free energy courtesy of Mr. MTA!”

What is this, a blinky for ants?

[Mike Harrison] is known for incredibly tiny soldering. Now he’s claiming a “world’s smallest” in the form of a stand-alone LED blinker, and we think he’s got the record.
He brought it along with him to Friday’s Beagleboard Bring-a-Hack, and we got a…

Is the era of cheap Chinese radios about to end for Americans?

There was a time when a handheld radio transceiver was an object of wonder, and a significant item for any radio amateur to own. A few hundred dollars secured you an FM walkie-talkie through which you could chat on your local repeater, and mobile radio…
