WattWise is a command-line interface (CLI) for power monitoring smart plugs. It can track power consumption and throttle CPU usage based on electricity prices. It supports TP-Link plugs directly and integrates with Home Assistant.
This article details a DIY atomic force microscope built from mostly junk parts. It utilizes a laser-based deflection reading system instead of traditional piezo motors, achieving 35-um resolution with readily available materials. The project focuses on simplicity and cost-effectiveness, making it suitable for educational purposes.
The article describes a project where someone developed a software-defined GPS receiver from scratch using Python and an RTL-SDR dongle. The project tackles the 'coarse' positioning capability of GPS, achieving location resolution within 24 seconds from a cold start. The article highlights the project's accessibility and potential as a starting point for further exploration of GPS technology.
The article discusses the challenges faced by hobbyists when building antennas like Yagi and WiFi cantennas, emphasizing the importance of antenna size and tuning to the target frequency for optimal signal performance. It references a webinar by Dr. Jonathan Chisum, highlighting the practical insights beyond textbook theory that can improve antenna design.
A 6502 system emulated in a busybox ash shell script, featuring RAM, ROM, and an emulated serial port on STDIO, with built-in monitor and debugger.
A modern replica of the 1955 Elektronensaldierer ES 24, built by Heinz Nixdorf, is on display in the HNF computer museum. The replica features 204 vacuum tubes and a USB interface for modern communication, making it a fascinating blend of old and new technology.
A guide on using large language models (LLMs) for programming tasks, including examples, strategies, and useful tips for effectively using AI assistants like ChatGPT and Claude.
A USB stick equipped with a Raspberry Pi Zero W runs a large language model using llama.cpp. The project involves porting the model to an ARMv6 architecture and setting up the device as a composite that presents a filesystem to the host, allowing users to interact with the LLM by creating text files that are automatically filled with generated content.
Pomelo is a complete low-power gamma ray spectrometer designed for independent use or integration into other projects. The repository includes hardware versions Pomelo Core and Pomelo Zest, with details available on Hackaday.io. It is licensed under MIT, featuring a variety of files primarily coded in C.
An individual has created a raycasting display engine that runs entirely within bash, inspired by the techniques used in Wolfenstein 3D. This project explores the limits of bash for graphical applications, addressing challenges such as performance limitations and the lack of floating-point support. The project's development process and challenges are detailed, with code available on GitHub and a visual explanation on imgur.
