What is it?The Chaos Computer is an analog computer that solves the Lorenz Equations to produce beautifully complex waveforms. The computation of the three non-linear differential equations is performed entirely by analog electronic components; there...
This project, in principle, is quite simple - it's two chips - a Cypress Semi CY7C65213-32LTXI and a Texas Instruments MAX3243ECRHBR. The former is a USB UART. It's pin compatible with the FTDI FT232R's QFN variant, but instead of a proprietary driver,...
Introduction Bipolar is not only a disorder but also a requirement for power supply for some devices. While most electronics is OK with a simple plus and minus, some will also require a mid-point, often called ground. It does not have to be connected...
Project Goal (the challenge & solution) The goal of this project is to build a bridge between Texas Instrument's Tiva™ C LaunchPad, based on the TM4C123GH6PM, and the Arduino form factor. The LaunchPad series of development kits already benefit from...

Browsing the social media of electronics enthusiasts I found a pokèmon-style PCB and I thought I'd make one too. (https://www.instagram.com/p/CG6-QrbrVJ8/?utm_source=ig_web_copy_link) I continued my research to find out if anyone had...
TL;DR I wanted a way to build a wireless Macropad which lasts for months on preferably two AA or AAA batteries. I'm already using a wireless Logitech keyboard and mouse, so building something using an existing receiver made sense to me...How bought a...
Construction The computer is divided in two seperate boards. First there is the mainboard. This is the upper PCB that carries the Compute module 4. The board handles the high-speed interfaces and carries the USB 3.0 host controller, the USB 2.0...
The story so far... I have been engineering my system for months, trying to learn as much as I can from YouTube about good sources for panels, inverters, batteries, battery management, etc. Big thanks to Andy at the Off-Grid Garage and the...
Five years ago, I modified a 1998 Furby into a Jorge Luis Borges animatronic. At that time all Furby hacks butchered the original toy, so my approach was to leave intact all the parts and electronics hijacking the audio. That “zen” hack...
Scouts BSA – Life Scout, Jacob Gates-Ehlers (a.k.a. Jake) from Troop 209 in the Pathway to Adventure Council, drove his wheelchair down to the rifle range with his mom Betsy like he did in years past, but this year was different. He would be able to...
Hey there! Welcome to the WeFlow project page! Below you'll find more details about the inspiration for the project and the work that went into it. If you would like to see a demo of the WeFlow in action, check out the demo video in the links section!...
Some history At the origin of the horizontal blade flip technology clock, patented in 1958 by Solari & C, sits the "Cifra 5". This clock was the first of a family of industrial timepieces developed from a technology studied by Remigio Solari, who revolutionized...
Why Did We Build This? "Prevention is better than cure" is one of the effective measures to prevent the spreading of COVID-19 and to protect mankind. Many researchers and doctors are working on medication and vaccination for corona. COVID-19 spreads...
The Technogym manual indicates that the RF HR receiver outputs a 5V and 30 ms pulse for each heart beat. A ESP32 with abilities will be the perfect µc. It's a easy job for it to read the incoming HR value and to output a pulse. Since the ESP32 works...
