At the end of last year I completed a project to build a Rasbperry-Pi-based DAC streamer. Effectively it was building a power supply for a Raspberry Pi zero and the connected Hifiberry DAC+ pro HAT. The idea of that power supply was to provide clean ...

The Amiga was one of my first computers, and now I'm fortunate enough to own an Amiga 500 and Amiga 1200 with various add-ons. Though I have to do some repair to get the disk drive working again (aging capacitors) I'm keeping an eye on the cu...

Now that I've discovered that I can program the RPi-Pico using the Arduino IDE (with Arduino-Pico or Mbed libraries), it's time to branch out and try some other RP2040 boards. The board I think that I'll may use a lot initially is the SparkFun P...

When I wrote my initial blog about the Arduino-Pico library, fmilburn mentioned that Arduino had just released an Mbed library that had support for the RPi Pico https://github.com/arduino/ArduinoCore-mbed/releases/tag/2.0.0 .   The github i...
