You can wire arcade buttons to the Gemma M0 which can be programmed in CircuitPython as a USB HID device (emulating keyboard strokes) to control any iCade compatible game on iOS! Plus, you can build your own stylish, rugged mini table using slotted aluminum extrusions and hardware! And, no soldering is required, just plug and play!
Build and code a radio communication system that notifies you of incoming messages, for example via automated puppet, and then displays the message on the Micro:Bit LED screen. No prior experience coding or using hardware is necessary. But! As this project involves communication (a two-way street), it’s a project for two or more people. Grab a friend, a micro:bit each, and build it together! Yayy collaboration! :D
The Basic String Car is a simple project that consists of a battery, motor, pulley, and a bit of fence wire. The initial design of the car was made from repurposed parts and materials found in Grandpa's basement workshop. This version uses some commercially-available parts, but could be hacked with parts gleaned from old CD players, for example. What modifications and improvements would you make?
The PiUART adds a MicroUSB to serial connection so you can use any serial port software to connect to the Pi's console. It plugs in and is fast and easy to add whenever you need to connect to your Pi. You can power your Pi through the microUSB port and then use the switch whenever you want to cut power, without having to unplug the cable.
The Adafruit Trinket M0 may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's our lowest-cost CircuitPython programmable board!
The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows you to flash firmware to the device directly from the command-line using the on-board USB Serial converter and the 'newtmgr' tool, so you can get started right away with no additional hardware required. For more advanced debugging, however, you can use a Segger J-Link and the on-board SWD debug connector, which gives you access to a more powerful set of development tools and options.
The Adafruit TPL5111 Reset Enable Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low
This project will turn your Raspberry Pi Zero W into a ad-blocking local DNS server with Pi Hole. When it is asked for the IP address of ads.adserver.com (for example) it will return nothing! So you will never even connect to the ad server and get the ad. Your connection will be faster, less data, and no intrusive ads. It works great on computers, tablets, phones, etc. Even if you cannot run an ad-blocker plugin on your phone or tablet, this will work and ad-blocker-detectors can't tell you're running it.
A different take on the beginning maker's second project (a clock being the first, of course). We added a motion detector to activate the fan when you're soldering and a USB reading light to eliminate the shadows. The unit employs a USB-rechargeable lithium-polymer battery and provides a separate USB port for the lamp. This solder fume extractor fits into an off-the-shelf enclosure; 3D printing isn't required. Drilling and cutting the enclosure requires some intermediate fabrication skills, but a layout and drilling template is provided to make it easier to prepare the plastic case.
