ItsyBitsy M0 Express

ItsyBitsy M0 Express is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital GPIO pins (12 of which can be analog in, 1x analog out, and 13x PWM out). It's the same chip as the Arduino Zero and packs much of the same capability as an Adafruit Metro M0 Express or Feather M0 Express but really really small. So it's great once you've finished up a prototype on a Metro M0 or Feather M0, and want to make the project much smaller. It even comes with 2MB of SPI Flash built in, for data logging, file storage, or CircuitPython code.

Sediment_level_logger

“Knowledge of sediment erosion and deposition can be useful for a variety of engineering, marine science, and environmental applications, but collecting detailed sediment level time-series measurements can be challenging, particularly in coastal marine environments. We developed economical and open-source sediment …

Robot Arm Built with Completely Re-made Servos

“6-axis robot arm built with hacked servos and 3D-printed parts demonstrating smooth inverse kinematic movements. This is a very long project in the making for me. You could say that it started when I ordered six endless servos in middle …

GPS interface using uLisp

“In this post I’m going to write about my experiments with interfacing a low-cost serial GPS module directly to uLisp, to create projects such as a GPS clock: I’ll also describe a GPS speedometer and odometer, and a …

CircuitPython 7-Segment Character Clock

“A desk clock built from a few Adafruit boards & brass rods for structure/connections. A desk clock built from a few Adafruit boards & brass rods for structure/connections. This small clock is actually my second project; it was started and …

Visible Lisp Computer

“The Visible Lisp Computer is a Lisp interpreter that displays the contents of the Lisp workspace on an OLED display, so you can see program execution and garbage collection in real time. It’s a special version of my uLisp …

A NeoPixel Pomodoro Timer

“Help manage your time and take regular breaks with this Pomodoro Timer project. I know many people who get value from a simple tool called the Pomodoro Technique. It’s a time management technique used to break work into periods …

Motorized Turntable

“When you think of the word turntable, you might think of something that you play a record on, but for this project, at least, we’re going to build a different type of turntable. A turntable, in the video and …
