Fresh hacks every day
[Marko] created a robot that prints burritos. Truly, we've reached new heights as a species. The Burritob0t is based on the ORD Hadron 3d printer with a pair of air compressor/syringe-based extruders based on the Makerbot Frostruder.

If you've got a few reel-to-reel recordings of 1940s radio, how do you transfer those to a digital medium? [Evan Long] and his dad used a credit card reader built for the iPhone to transfer a vintage [Art Kassel] recording from magnetic tape to the digital domain of .MP3s. A few months ago, we saw what goes into these Square credit card readers. They're just a magnetic tape head with a resistor … [Read more...]

[Robert]'s cosmic ray detector works by detecting the output 9 Geiger tubes on the y-axis and 9 Geiger tubes on the x-axis with a coincidence circuit. When a cosmic ray flies through the … [Read more...]
It seem [Balint] is becoming somewhat of a SDR guru around these parts; in the past few months, he's gotten a USB TV tuner receiver working with GNU Radio, started a software defined radio tutorial YouTube channel, and even used this project to listen in on conversations between airplanes and air traffic control. This time, [Balint] is back using this cheap USB TV tuner for radio direction … [Read more...]
