Same experience here, plus serial port drivers that don't work, bootloader bugs causing bricked machines in the field. This on a platform nearly a decade old! The hardware is great…

Really cool tool, but perhaps not for the original use-case. I often find myself trying to figure out what call tree a large Bash script creates, and this looks like it visualises …

There are multiple NOx sources during combustion. Fuel NOx is only one of them, which you quite rightly point out is not dominant in methane combustion due to the rarity of nitroge…

Picochip?

DSP engineer here:- the typical way to do this for better performance would be to do the FM modulation of each channel at a lower rate, say 100kHz, then use an FFT-based channelise…

Low cost and low power DRM radio receiver is now available for general sale. It can receive DRM/AM/FM, with an integrated class-D amplifier. Dev kits and modules available from Mou…

This looks very similar to the Picochip designs used in a lot of small cellular base stations for SDR. I hope it is similar, because those were fantastic chips to program for. That…

You're probably right. I was put off by early DAB deployments, and haven't tried with DAB+. I would be interested to try again with the new standard.

That is true, although I know of one company close to production of a <10$ module for OEMs to integrate.

Agreed, but the alternative here is AM which has never been good quality. DAB was a big step down from FM quality because the choice of codec / bandwidth assigned to stations was p…

AM radio is a pretty poor standard considering how much power and bandwidth it uses, due much to the very limited modulation technology available in the 1920s. DRM (no not that DRM…

I've done some work with Octasic's Opus DSP system [ http://www.octasic.com/technology/opus-dsp-architecture ] The cores themselves are asynchronous, with all of the benefits of lo…

This is what surprised me too! That's just asking for problems.
