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.

Rust on the RP2350 (2024) (thejpster.org.uk)
Today sees the announcement of the latest additions to Raspberry Pi's microcontroller line-up - the RP2350 family. I've had prototype units for a while, and you can run Rust code on it today. To my knowledge this is the first ever microcontroller launch with Rust support out-of-the-box.

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.

Can You Get Rich Using a Raspberry Pi to Mine Cryptocurrency? (wired.com)
In olden times, people dug holes in the ground to look for gold. They called it mining. But why is gold valuable, anyway? Well, mostly because humans decided it was valuable. Yeah, but why gold? Well, one cool thing about element 79 is that it doesn't interact with the oxygen in the air, so it stays shiny all the time. Also, it's rare enough to be a status symbol.

Build a tiny CA for your homelab with a Raspberry Pi (smallstep.com)
TL;DR In this tutorial, we're going to build a tiny, standalone, online Certificate Authority (CA) that will mint TLS certificates and is secured with a YubiKey. It will be an internal ACME server on our local network (ACME is the same protocol used by Let's Encrypt). The YubiKey will securely store the CA private keys and sign certificates, acting as a cheap alternative to a Hardware Security Module (HSM).

How I built this website on a Raspberry Pi (mirawelner.com)
As of the time of writing this, the Raspberry Pi 5 has recently been released. Some people are buying it excitedly, while others think that its value over previous models doesn't warrant the price increase. In any event, many people will be implementing various projects on their new (or old) Pis.
