This is the weirdest IC footprint I've seen and was convinced I'd made a mistake. Nope. Board for the @opulo Lumen PnP feeder. Designed for BOTH a STM32F031 LQFP48 AND a UFQFPN32, stacked on top of each other. Designed during chip shortage. Very clever.

In celebration of #MicroPython's 13th birthday - I wrote a few words! www.kevsrobots.com/blog/micropy...

The curriculum is designed for my BEAPER Nano, BEAPER Pico, and ARPS-2 circuits. Since they're easy to build into robots, I just added line-following and Sumo robot program templates to their repositories! Find all of the programs in each circuit's Beginner Activities folder: github.com/mirobotech

So, there’s a front porch for spacecraft, and a front porch for NTSC video signals. How many other engineering disciplines have a front porch? 🤔

April 10, 1849 – Safety Pin Patented On April 10, 1849, American inventor Walter Hunt was granted a U.S. patent for the safety pin. His clever design, a coiled brass pin that clasps and covers its sharp point, provided a safe, spring-secured fastener and became an enduring tool in clothing and life.

Oscilloscope? Nah, I just programmed my own. 🤣 I'm measuring the TRIG -> ECHO time delay of different SONAR modules and comparing total distance measurement time with a VL53L0X ToF (Time of Flight) sensor module.

It's freebie Friday!! Still trying to bend through-hole component leads by hand? Here, use this handy lead bender instead: makerworld.com/en/models/69...

Now that civilization won't end tonight, I thought I'd let you know that my APRILFOOLZ sale will, for real, end tomorrow night. So, pick up a kit at 20% off and start learning microcontroller programming – and build a robot – before the next world-ending event! lectronz.com/stores/mirob...

The juxtaposition of the very public and amazing science and engineering taking place right now and, *waves hands* all of this, is such a bizarre moment in time. Like the crew onboard Integrity we're all part of spaceship Earth, and we need to work together in order for all of us to succeed. ☮️

Remember when computers had hard disk activity lights? Arduino Nano ESP32 has an LCD activity light! 🤣 😎 (Arduino's yellow LED is wired to the SPI SCK line for the LCD display.)

It's Good Friday, but any day until April 8, 2026 is a good day to save 20% on my ARPS-2, BEAPER Nano, and BEAPER Pico beginner electronics and robotics kits! Use code APRILFOOLZ (applies to kits, not bare PCBs) on @lectronz.com : lectronz.com/stores/mirob...

I've also created a simple #MicroPython bar graph module using my LCD driver that lets you create solid or segmented bars, with or without borders! Find all of the files in my BEAPER Nano and BEAPER Pico LCD repositories: github.com/mirobotech

It's freebie Friday!! I've just updated my #MicroPython LCD driver for the ST7789 LCD display used in BEAPER Nano and BEAPER Pico with my new built-in font! Here it is drawing and timing graphics primitives:

I've been working on a simple font that I can build into a #MicroPython LCD driver to make it super easy for beginners to use! 🤩 Here's a view of all of the glyphs, and a second pic of the font doing work in a bar graph module I'm working on for BEAPER Pico and BEAPER Nano. 😎

The first one might be too wide, and the second one might be too narrow. Guess I'll have to create another one that's just right. 🤣

MicroPython's 8x8 pixel frame buffer font is too small for the 240x240 pixel display on BEAPER Nano and BEAPER Pico, so I'm working on designing a custom 16 pixel high font that I can build into the MicroPython LCD display driver (top of both photos – bottom is Reddit Sans 16). What do you think?

Having played with a BEAPER Pico,I can say whole heartedly they are amazing systems with great resources and a ton of examples to get running quickly. 20% off is a bargain on top of a bargain! #EduSky #RobotClasses #CodingWithRobots

Ai has done to coding what Arduino did for electronics, there is an influx of people making things they wouldn't otherwise, but in horrid ways (that work for them) This is the way.

Don't be a fool, start your robot journey today! For a limited time, save 20% on ARPS-2, BEAPER Nano, and BEAPER Pico PCBs plus electronic parts kits using code APRILFOOLZ at checkout on @lectronz.com robot: lectronz.com/stores/mirob...

In honor of (hopefully) today's launch of NASA's Artemis II mission, the first crewed mission to orbit the Moon in more than 50 years, here is a to-scale graphic of exactly how far away the Moon actually is. (Click image to expand.) You could fit about 30 Earths between the Earth and the Moon!
