MakerSpace #05 - Digital Issue

Coin Counter
Parking meters and vending machines detect and count the coins you insert, but how do they work? We'll show you how to mimic the functionality with some particleboard, a Raspberry Pi Pico, a few extra chips, and some Python code.

Raspberry Pi 5 AI Kit
What happens when the Raspberry Pi's makers and AI specialist Hailo collaborate on a project? We get an official AI kit HAT+ for the Pi 5 that adds an AI accelerator chip.

Proxmox on the Pi
Proxmox-Port, an unofficial ARM port of Proxmox VE, offers a virtualization solution for the Raspberry Pi. We test it out on the Pi 5.

Raspberry Pi 5 Case
The official Raspberry Pi 5 case is not the perfect solution for all applications, so it makes perfect sense to design and 3D print your own case.

Raspberry Pi 5 Remote Boot
In addition to enhanced performance, the Raspberry Pi 5 also comes with some new hidden functions, including options for time-controlled and remote start-up and shutdown.

Fischertechnik Maker Kit Car
Build a remote control car with the Fischertechnik Maker Kit Car, MicroPython, and ESP32 microcontrollers.

PiJuice Zero
The Raspberry Pi Zero is a frugal little computer. But without a power socket, you might be surprised how quickly it can drain a battery. Active power management is the order of the day.

Off-Grid File Sharing
A battery-powered WiFi hotspot can provide useful services like file sharing even when you're off the grid. A Pi Zero 2 W as the hotspot with ownCloud installed does the trick.

Pi Zero-Based Weather Cam
Combine a Raspberry Pi Zero and the new Raspberry Pi Cam 3 to create your own cost-effective, energy-saving webcam.

Jellyfin
The top dogs in the media server space now face some competition from Jellyfin, a relatively young project that impresses with a number of innovations.

Weather Station
A DVB-T stick retrieves information from a professional weather station and stores it in a database for downstream processing.

CO2 Sensors
Monitor your indoor air quality with an inexpensive CO2 sensor. We look at three candidates to help you find the best solution.

Matter
The new vendor-independent, open Matter standard for IoT and smart home devices has what it takes to revolutionize the market. We describe its basic principles and explain how Matter works.

Run DOS Applications
There was a time when almost everyone used DOS. While Windows, Linux, macOS, and maybe Android and iOS are the dominant operating systems for today's consumer market, you can still get DOS.

PC-BASIC
BASIC, one of the oldest programming languages, helped make home computers popular in the 1980s. You can Run the old GW-BASIC programs from the DOS era in PC-BASIC, a modern emulator.

Embedded Rust
Rust, a potential successor to C/C++, claims to solve some memory safety issues while maintaining high performance. We look at Rust on embedded systems, where memory safety, concurrency, and security are equally important.

Sensor Data in SQL Tables
If you need to store long-term historical data, you can cobble together some Arduino modules, sensors, and displays and get them all to talk to an SQL server.

Node-RED and SVG
Use an SVG graphic widget on your next Node-RED project to get a visual representation of your automation setup.

Julia on the Pi
Create GUIs and a web app that connects to sensors.

Snek
Reuse your old Arduino hardware while learning Python.​
