A DIY ELECTRONIC LOAD FOR DC-DC CONVERTER CHARACTERIZATION

Nouvelles & Mises À Jour / Par Tismail

The heart of the system is an Atmel ATmega328P AVR microcontroller with 32kB of Flash and 2k of RAM running at a whopping 16MHz. It interfaces an I2C 12bit DAC (the MCP47FEB21A1) and the LTC2992 dual power monitor chip. The USB serial interface uses the MCP2221A bridge. The display is a classic 16×2 LCD. On the analog part, 10mΩ

MASS PRODUCTION 3D PRINTING HACK CHAT

Arduino News / Par Ibrar Ayyub

We’ll take a wild guess and say that right now, within arm’s length of wherever you’re reading this, there’s something that was produced by injection molding. Look around; it’s there someplace, and whatever it is, thousands or perhaps millions of other identical artifacts were produced along with it, all by squeezing hot plastic into intricately

LINUX, RUNNING ON NOT A LOT

Arduino News / Par Ibrar Ayyub

There are many possible answers to the question of what the lowest-powered hardware on which Linux could run might be, but it’s usually a pre-requisite for a Linux-capable platform to have a memory management unit, or MMU. That’s not the whole story though, because there are microcontroller-focused variants of the kernel which don’t require an

2023 CYBERDECK CONTEST: A TODDLER’S CYBERDECK

Arduino News / Par Ibrar Ayyub

[Josh] has a child and what do children like more than stuffing random things into their mouths? Pushing buttons, twiddling knobs, and yanking things of course! So [Josh] did what any self-respecting hacker would do and built his little man a custom cyberdeck. The build follows the usual route of some electronics wedged into a pelican-style

HACKADAY PRIZE 2023: UNIVERSAL TENSILE TESTING MACHINE

Arduino News / Par Ibrar Ayyub

Material testing is important in big industry, where manufacturers must be able to trust the properties of the raw materials they’re using. The rest of us generally take a supplier’s word for it that they’re giving us what we’ve paid for. However, you could always take on material testing yourself with the Universal Tensile Testing Machine

ESP32 BURNINATOR IS A TINY LASER ENGRAVER

Nouvelles & Mises À Jour / Par Tismail

As the name implies, a linear stepper is linear a variation of the rotary stepper motor design, radially cut and laid out flat. It is similar to the rotary version in operation and performance, and it typically runs as an open-loop system with the ability to provide high resolution at high speeds and accelerations. As
