My new Raspberry Pi Zero web server (paulcapewell.com)
Had a lovely sunny weekend of first birthday parties (three of them!) in the park and some gardening. But I've also been metaphorically squirrelled away working on a little project I've been semi wanting to do for years now: set up a self hosted web server.

My brief attempt at learning about Software Defined Radio on Ubuntu (mendhak.com)
When my previous office building shut down, I ‘inherited’ a Pi-aware which had been set up many years ago. I was vaguely aware that it made use of something called RTL-SDR, but I didn’t actually understand what that meant. I thought it was just for tracking aircraft, but it turns out the receiver is a general purpose radio receiver and can be used for other things. The SDR simply stands for Software Defined Radio, of which there are many implementations.

Pi Pico Rx – A crystal radio for the digital age? (readthedocs.io)
The Pi Pico Rx - may be the answer to that question. While it may not be quite as straightforward as the crystal radio, the Pi Pico Rx presents a remarkably simple solution. Armed with just a Raspberry Pi Pico, an analogue switch, and an op-amp, we now have the power to construct a capable SDR receiver covering the LW, MW, and SW bands. With the ability to receive signals from halfway around the globe.

Raspberry Pi Pico audio player (blogspot.com)
For an index to all my stories click this text.After all the proceeding stories the time has come to build a complete stand-alone audio player with the Raspberry Pi Pico. The audio quality is not Hifi but it is really good !! Good enough as a player in your mancave, bedroom or even as a portable player. I have made a permanent setup and using it to play music and podcasts.

Show HN: Slime OS – An open-source app launcher for RP2040 based devices (github.com/abeisgoat)
Slime OS is an app launcher for the PicoVision (and soon other RP2040 and RP2350 devices). It was originally designed for the Slimedeck Zero, a mini cyberdeck project. However I hope to expand it to other devices and form factors.
