2026-07-11T09:20:39Z

Hi, community! I’m writing this post because I’d like to share my radio ground station project, built using an old Raspberry Pi 3 that I found in a box at home. First, I’d like to give you some context. A few months ago, I started l...(read more)

Custom Manufactured RP2040 Boards, Part 3 - Final Results

2026-07-06T18:42:50Z

I wanted to make a custom RP2040 microcontroller-based project, and in Part 1 it was discussed how the schematic and PCB files of Raspberry Pi’s custom minimal RP2040 project were adapted and modified. In Part 2, the PCB layout was improved for...(read more)

Adding Wireless Capability to Custom RP2040/RP2350 Projects: Pi Radio Module 2 - Anyone tried it?

2026-06-30T16:29:26Z

I just noticed the other day that this thing existed; it supports 2.4 GHz wireless (not 5 GHz), and Bluetooth LE (BLE); the manufacturer part code is RMC20452T , also known as RM2 and it costs about $4. Underside; the board is 16.5 x 14.5...(read more)

Making a Custom RP2040 Project with KiCad, Part 1!

2026-06-24T15:25:10Z

Partly out of curiosity, and partly to test some aspects of a workflow for other projects, I decided to create a custom RP2040 board. In most cases, there’s no need to do this; it may well be more expensive than simply using a ready-made Raspbe...(read more)

E-Z USB to I2C Adapter and UART Bridge

2026-06-09T15:49:12Z

This E-Z USB to I2C and UART Bridge adapter is a bit of a niche project! I doubt many people may have the same precise needs as me, but I figured I’d document it, in case anyone comes across a use one day. In brief, this project converts a Pi P...(read more)

Adafruit Pi Pico Enclosure: A Quick Review

2026-01-28T21:43:15Z

I recently purchased an unusual Adafruit product: a Pi Pico enclosure. Rather an odd product, it's really more for standalone projects because there is no space to easily attach additional hardware. The case is two-part and snaps together, but e...(read more)

Syslog: Sending Log Messages to a Server with MicroPython

Introduction Installing MicroPython on your microcontroller board allows you to write and immediately run Python code, without needing to build or compile the code. It’s a really fast way of creating applications. Usually I use print statements...(read more)

GCC RISCV for Pico toolchain version 15.1 released

2025-08-06T18:08:04Z

This is a bit of a surprise. Raspberry released a GCC 15.1 version of their Pico RISCV toolchain. That's a more recent version than the current (at the time of writing, 14.2) version of the mainstream ARM toolchain. If you are using the VSCode P...(read more)

I made a Tamagotchi with a Job, Debt and a Dr*g Problem

2025-05-10T15:00:17Z

This project is a cursed reinterpretation of a Tamagotchi, but instead of caring for a cute little creature, you're managing the brutally cynical arc of human life going through all the levels of the Maslow's pyramid. Think of it as a social ...(read more)
