Attiny Programmer (using Arduino UNO)
https://www.electronics-lab.com/attiny-programmer-using-arduino-uno/
by CrtSuznik @ instructables.com: The Arduino UNO is small, but if you require your project to be in a small enclosure, the UNO might be way too big. You could try using a NANO or MINI, but if you really want to go small, you go tiny, Attiny to be precise. They are quite small, […]
DSETA board with an AT89C51ED2
https://www.electronics-lab.com/dseta-board-at89c51ed2/
Jesus Echavarria tipped us with his latest DSETA board with an AT89C51ED2. Some months ago I review the DSETA board due the obsolescence of the microcontroller. I use this board in some projects succesfully. But when I try to manufacture a batch of this boards, I found that the microcontroller (AT89C51RE2) was obsolete. So, the […]

Are Today’s MCUs Overdesigned? A Research Team Has The Answer
https://www.electronics-lab.com/todays-mcus-overdesigned-research-team-answer/
MCUs are called microcontrollers because they embed a CPU, memory and I/O units in one package. Apparently, today’s MCUs are full of peripherals and in most cases they are not used in the application, and from an engineering point of view this is a waste of money and energy, but on the other hand, for […]
Open-V, The Open Source RISC-V 32bit Microcontroller
https://www.electronics-lab.com/open-v-open-source-risc-v-32bit-mcu/
Open source has finally arrived to microcontrollers. Based on RISC-V instruction set, a group of doctoral students at the Universidad Industrial de Santander in Colombia have been working on an open source 32-bit chip called “Open-V“. Onchip, the startup of the research team, is focusing on integrated systems and is aiming to build the first system-on-chip designed in Colombia. The […]
A Mass Programming Bench for ATMega32u4 MCUs
https://www.electronics-lab.com/mass-programming-bench-atmega32u4-mcus/
“limpkin” @ limpkin.fr wanted to program some thousand of MCUs so he decided to build his own programming bench. He writes: As you may know I started the Mooltipass offline password keeper project more than 2 years ago. Together with a team of volunteers from all over the globe I created two Mooltipass devices which were […]

“pinko” has designed a simple datalogger based on a PIC microcontroller that logs data on a SD Card. He writes: Some time ago I decoded to make a simple general purpose Data Logger with the following parameters for the project. it should have very simple design that should be doable by most amateurs the Data […]
Emulate an Apple ][ on an AVR Microcontroller
https://www.electronics-lab.com/emulate-apple-avr-microcontroller/
The Apple II personal computer, which stylized as Apple ][, is an 8-bit home computer and one of the first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak and developed with Steve Jobs. Apple ][ was introduced in 1977 at the West Coast Computer Faire by Jobs and was sold several […]
