Fresh hacks every day
Who has an airport carry-on X-ray machine sitting in their garage? Apparently [Mike] does, and he's sharing the fun by posting a video teardown series that really digs into the machine's hardware and operating system. At this point the series includes six lengthy segments. The first episode, which you'll find embedded after the break, starts with an external overview of the hardware. [Mike] … [Read more...]
Join [Fran] as she dons the hat of an electronics archaeologist when looking at this vintage circuit board from the space race. As part of her personal collection she somehow acquired a Launch Vehicle Digital Computer board for a Saturn V rocket. This particular unit was never used. But it would have been had the Apollo program continued. [Fran] is enamored with this particular board because … [Read more...]
After building a homebrew x-ray backscatter imager, [Ben Krasnow] realized he had nearly all the components to build his own CT scanner, able to make a 3D model of the inside of a frozen chicken. Basically, a CT scanner takes dozens of x-rays of an object and reassembles them with the help of fancy algorithms to allow doctors to peer inside a human body. The CT scanners you'll find at your … [Read more...]
[Ben Krasnow] built his own version of the TSA's body scanner. The device works by firing a beam of x-rays at at target. Some of the beam will go through the target, some will be absorbed by the target, and some will reflect back. These reflected x-rays are called 'backscatter', and they are captured to create an image. In [Ben]'s setup a rotating disk focuses x-rays into beams that travel … [Read more...]
This is an x-ray detector built by [Ben Krasnow]. It's an interesting combination of parts working with an oscilloscope. The result is an audible clicking much the same as you would hear from a Geiger counter He's measuring backscatter, which is the reflection of x-rays on other objects. Because the signal will be quite weak compared to waves emitted directly from an x-ray source he needed a … [Read more...]
It's not every day one of the builds on Hackaday gets picked up by a big-name publication, and it's even rarer to see a Hackaday contributor grace the pages of an actual print magazine. Such is the case with [Adam Munich] and his home-built x-ray machine. We first saw [Adam]'s x-ray machine at the beginning of this year as an entry for the Buildlounge/Full Spectrum laser cutter contest. [Adam] … [Read more...]
The results of the Full Spectrum Laser contest over at Build Lounge have been announce. The top prize of a 40 watt deluxe laser cutter goes to [Grenadier] for the portable x-ray machine we saw at the beginning of the month. We think this is an excellent choice for top prize because, come on, this is pretty hard-core. Taking second place was a Christmas light show choreographed to music. The … [Read more...]
