Used Adafruit’s M0 feather proto board and their OLED feather wing to build a quick PWM fan contoller. The M0 version was needed for the faster CPU to be able to drive the required PWM frequencies. To be fair you can probably find a cheaper solution already built on the internet, but where’s the fun…read more
This project is do-it-yourself 3D printable chassis. It is built around standard 2020 frame construction used in DIY 3D printers and CNCs. The design files are available online at Thingaverse, thing:4297391. Note, this is a derivative work, the 2020 beams are based on other designs. The new parts were the brackets and panels. Where possible…read more
After almost a year sitting on the bench, we did some more work on the digital scoreboard. After some paint, a bit of mechanical hacks and software bug fixes we have a working scoreboard. It can be controlled from smartphone or even smartwatch using BluetoothLE. It runs off 4 D-cell batteries, DC adapter or USB…read more
There was an Arduino Yun sitting around that needed a home so we adapted our water meter to this powerful little network board. It’s unfortunatel that the Yun is discontinued as it’s really a good fit for this type of project. It can be powered from ethernet, PoE. And being able to get to the…read more
WORK IN PROGRESS Cubic is a robot project that is making slow progress. It’s been an experiment putting some different projects together. It has two robot arms built with a mix of Dynamixel AX-12A and XL-320 servos and controlled with a OpenCM board. The base is a Sainsmart robot tracks kit. The motors are currently…read more
We made one of the Adafruit’s Pocket PiGRRL kits. It’s a really rewarding project, however it does involve a significant amount of soldering. When done you are treated to having an awesome handheld game platform. For more information see Adafruit’s website. Pocket PiGRRL (https://learn.adafruit.com/pocket-pigrrl/overview)
Had a good unboxing experience with Google’s AIY Vision Kit. https://aiyprojects.withgoogle.com/ The project uses a board with the Movius artificial intelligence coprocessor connected to a Raspberry Pi Zero W. The camera images are processor using their TensorFlow framework to recognize the emotions on faces. Very simple kit to get going with a lot of amazing…read more
Doing some I2C debug on an Arduino and OpenCM9.04c boards. Loving Labnation’s smartscope that plugs into a PC/tablet https://www.lab-nation.com/
This is a prototype of a digital scoreboard. It’s uses several 8×5 NeoPixel matrixes from Adafruit. The Arduino Uno is used to provide a game time and scores which is controlled by phone via Bluetooth. It’s definitely an early version which needs polish and cost reduction, but good for the backyard basketball hoop.
