Measuring the doppler shift of WWVB during a flight
We advertise 100 kHz as the lower edge of HackRF Pro ’s operating frequency range, but that isn’t a hard limit. While working on the design, I realized that it should work fairly well to pick up longwave time signals such as WWVB , broadcast at 60 kHz from Colorado, USA.

The Joys of Unix Keyboards
A decade or so ago while helping a friends father clean out an old building, we came across an ancient Sun Microsystems server. We found it curious. Everything about it was different from what we were used to. The command line was black text on a white background, the connectors strange and foreign, and the keyboard…

Using a tiny HC32L110 ARM chip
A while ago, Hackaday highlighted a new chip, the HC32L110. This chip was one of the many ARM-based microcontrollers that sprung up in China, but this one was remarkable because its diminuitive size: it came in an 16-pin WCSP package of a miniscule 1.6x1.4mm. Aside from that, it seems to be a chip that is somewhat…

Hiding your data in plain sight: USB hardware hiding
This article will describe the possibility of hiding data in any kind of USB hardware. Even though USB data carriers come in various sizes and forms, which already sometimes makes them hard to recognize, this approach could even make it worse. Any USB device could be a data carrier and thus from a forensics point of…
