Z-Uno was designed to allow people to make their own IoT devices for their Smart Homes. Many times we were asked "Is there a pressure/radiation/water level/.../whate ever sensor in Z-Wave?" and we found that it would be cool if people can make their...
Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips,...
Briefly about architecture and instruction set - it is 8-bit design with 8 registers: 000 - 0 (always zero) 001 - A (accumulator) 010 - B 011 - C 100 - D 101 - E 110 - F (flags and 3 higher bits for jumps) 111 - G (8 lower bits of program counter) Flags...
A powerfull dev board with the ESPRESSIF™ ESP32-S2®, a high resolution display, a RGB LED, a battery charger and a bunch of GPIOs. There are many ESP32 board on the market but very few with the new ESP32-S2 which handles USB communications, new...
Note: this is a complex project with many details. For the short version, please see:Portable environmental monitor presentationProduction ready design documentIntroductionLast year (2014) I put my spare time to some really good use: I designed my first...
A clock built with eight authentic soviet vacuum fluorescent display (VFD) tubes, a custom designed circuit board, firmware and 3d-printed case It is an evolution of Phalanx. Many of the firmware improvements made for Ameise also trickled down to Phalanx...
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...
What if I told you it was possible to SAFELY use ANY SmartPhone as a robot brain? On any smartphone with a browser, load a freely hosted github.com webpage with Javascript that blinks areas on the screen to send motor commands to an e.g. Arduino....
Project Overview Video for Hackaday Prize 2023: The End Result The Plan In principle it is simple: by connecting different combinations of binary value resistors in parallel, and assuming a constant input voltage, we can consume any arbitrary amount...

Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...
Links to project details (GIT, Wiki, Docs) are on the left. The laziest intro to this project is the 2-minuite video created for THP Quarterfinals (i.e. the first video I made):Or even better, see my full 5-min final video (there is also the semifinal...
