Nanocounter is an accurate frequency counter using an FPGA, STM32 and a bluetooth android app

Andy Brown has designed and built a frequency counter using an FPGA, STM32F072 and an Android GUI – the Nanocounter: After studying the above counting methods I decided on the following goals for my frequency counter, which I’m going to call Nanocounter. Very accurate measurement over a range of 1 to 50MHz. This would cover the range […]

An Android reflow controller that anyone can build

Andy Brown published a new build, an Android reflow controller:  The only surface mount device on this PCB is the MAX31855 and it has a low number of generously spaced pins. I eschewed my hot air gun, previous reflow oven and hot plate in favour of a plain old iron and the tack-soldering method because […]

Android flight tracker uses ADSB data from RTL-SDR

Nikos has developed an Android app which works with the RTL-SDR dongle to demodulate the ADSB signal from aircraft and overlays the position of the aircraft on a high resolution offline map. So the user can use the App without Internet connectivity, on board an aircraft in real time! Nikos’ “Track your flight Europe” app […]

Single Cell Software frees Korg Volca Sample from iOS chains

If you experiment with electronic music, you’ve probably heard of Korg’s latest addition to their Volca line known as the Volca Sample.
