IoT Corner Arduino, the Italian company known for its maker-friendly ecosystem of microcontrollers, launched a new professional-grade development board for IoT. The Portenta H7 features a dual core processor, with an on-board graphics accelerator that allows users to connect it to an external monitor via the USB-C port. The Portenta H7, which supports WiFi and […]

Working with graphics on microcontrollers has always meant focusing on making the most of limited resources. Particularly in the 8-bit era, all manner of tricks were used to get low-performance chips to achieve feats beyond their lowly station. However, these days, we’re blessed with 32-bit workhorses with clock speeds in the tens, or even hundreds,

Developed in the dark hours of the night, between 2 and 8 o’clock in the morning of August 19th by Marcelo Samsoniuk, the DarkRISC-V stack is an experimental open source implementation of the RISC-V standard targeting the low-cost Xilinx Spartan-6 family of FPGAs. Following a week of debugging, Samsoniuk has released the implementation to GitHub

Just when we think we’ve seen all possible combinations of 3D printing, microcontrollers, and pretty blinkenlights coming together to form DIY clocks, [Mukesh_Sankhla] goes and builds this geometric beauty. It’s kaleidoscopic, it’s mosaic, and it sorta resembles stained glass, but is way cheaper and easier. The crucial part of the print does two jobs — it

Along with all the colorful, geometric influence of Memphis design everywhere, giant wristwatch clocks were one of our favorite things about the 80s. We always wanted one, and frankly, we still do. Evidently, so did [Kothe]. But instead of some splashy Swatch-esque style, [Kothe] went the nerdy route by building a giant Casio F-91W to hang

If you want strangers to give you well wishes on your birthday out in the real world, you have call attention to the occasion by wearing a pointy hat or a button that says ‘today is my birthday, gimme presents’. But on your reddit cakeday, aka the day you joined, you’re automatically singled out with

Story This project was inspired by Fran Blanche’s NIMO Tube video. It’s a fascinating video and I recommend watching it for detailed information on NIMO tube operation and history. In short, the NIMO tube was a single digit CRT display manufactured for a brief period in the late 1960’s and early 1970’s. After watching Fran’s video

This Arduino based digital clock is synchronized by the 60Hz power line. It has a simple and inexpensive common anode 4 digit 7 segment display which shows hours and minutes. It uses a cross over detector to detect when the incoming 60Hz sine wave crosses the zero voltage point and derives a 60 Hz square

There is no need for a wordy introduction to I2C protocol. We all know it’s main parts – 2 wires, multiple slaves, sometimes multiple masters, up to 5MHz of speed. Often so have we all implemented an I2C connection. Still, every now and then, there’s that module that just won’t work. This time, we will do
