Milspec Teardown: CP-142 Range Computermilspec-range-computer-featuredtomnardi

Mon, 19 Feb 2018 15:01:38 +0000

As some of my previous work here at Hackaday will attest to, I’m a big fan of World War II technology. Something about going in with wooden airplanes and leaving with jet fighters and space capable rockets has always captivated me. So when one of my lovingly crafted eBay alerts was triggered by something claiming to be a “Navy WWII Range Computer”, it’s safe to say I was interested.

Not to say I had any idea of what the thing was, mind you. I only knew it looked old and I had to have it. While I eagerly awaited the …read more

The White Rabbit Nixie ClockWhite Rabbit Nixie Clockthehacksmith

Mon, 19 Feb 2018 12:01:56 +0000

Instructables user [hellboy] — a recent convert to the ways of the laser cutter — is a longtime admirer of Nixie tubes. In melding these two joys, he has been able to design and build this gorgeous work of art: The White Rabbit Nixie Clock.

Going into this build, [hellboy] was concerned over the lifespan of the tubes, and so needed to be able to turn them off when not needed. Discarding their original idea of having the clock open with servos, [hellboy]’s clock opens by pressing down on a bar and is closed by snapping the lid shut — …read more

Roll Your Own Rotary EncodersFRQDF9CJDOUSIHX.LARGEdpsm64

Mon, 19 Feb 2018 09:01:23 +0000

[miroslavus] hasn’t had much luck with rotary encoders. The parts he has tested from the usual sources have all been problematic either mechanically or electrically, resulting in poor performance in his projects. Even attempts to deal with the deficiencies in software didn’t help, so he did what any red-blooded hacker would do — he built his own rotary encoder from microswitches and 3D-printed parts.

[miroslavus]’s “encoder” isn’t a quadrature encoder in the classic sense. It has two switches and only one of them fires when it turns a given direction, one for clockwise and one for counterclockwise. The knob has …read more

Photographing Starman From a Million Miles Awaymain450lewinday

Mon, 19 Feb 2018 06:01:35 +0000

Love it or loathe it, launching a sports car into space is a hell of a spectacle, and did a great job at focusing the spotlight on the Falcon Heavy spacecraft. This led [Rogelio] to wonder – would it be possible to snap a photo of Starman from Earth?

[Rogelio] isn’t new to the astrophotography game, possessing a capable twin-telescope rig with star tracking capabilities and chilled CCDs for reducing noise in low-light conditions. Identifying the location of the Tesla Roadster was made easier thanks to NASA JPL tracking the object and providing ephemeris data.

Imaging the Roadster took some …read more

Turning A Car Into A Computer MouseCar as a computer mousestevenduf

Mon, 19 Feb 2018 03:00:14 +0000

[William Osman] and [Simone Giertz] have graced our pages before, both with weird, wacky and wonderful hacks so it’s no surprise that when they got together they did so to turn Simone’s car into a computer mouse. It’s trickier than you might think.

They started by replacing the lens of an optical mouse with a lens normally used for a security camera. Surprisingly, when mounted to the car’s front bumper it worked! But it wasn’t ideal. The problem lies in that to move a mouse cursor sideways you have to move the mouse sideways. However, cars don’t move sideways, they …read more

Hacker uses pineapple on unencrypted WiFi. The results are shocking! Film at 11.

Right on, we’ve got some 3D printing cons coming up. The first is MRRF, the Midwest RepRap Festival. It’s in Goshen, Indiana, March 23-25th. It’s a hoot. Just check out all the coverage we’ve done from MRRF over the years. Go to MRRF.

We got news this was going to happen last year, and now we finally have dates and a location. The East Coast RepRap Fest is happening June 22-24th in Bel Air, Maryland. What’s the East Coast RepRap Fest? Nobody knows; this is the first …read more
