Getting Started with Microsoft Azure and CircuitPython
There are a lot of IoT platforms out there, but if you want to build really big projects or run a business using IoT you'll need to use a platform that provides support for projects of that scale, like Microsoft Azure. This guide will walk you through how to get started with Microsoft Azure using a Feather ESP32-S2 TFT, a BME688 sensor and CircuitPython.
Walkmellotron: Cassette Player Mods
Build two different DIY solutions to the age old problem of how to speed control you Walkman with tape loops like an ersatz Mellotron.
Smart Mirror with PyPortal
Make a mini IoT smart mirror that displays weather information.
Adafruit QT Py ESP32-S3
The ESP32-S3 has arrived in QT Py format - and what a great way to get started with this powerful new chip from Espressif! With dual 240 MHz cores, WiFi and BLE support, and native USB, this QT Py is great for powering your IoT projects.
Adafruit PAM8302 - Mono 2.5W Class D Audio Amplifier
This mono amplifier is able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D (very efficient) controller, able to run from 2.0V-5.5VDC. The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin to ground.
Mini GIF Players
Build a miniature display to showcase animated GIFs
Adafruit NAU7802 24-Bit ADC - STEMMA QT / Qwiic
The Adafruit NAU7802 contains a super-high-resolution 24-Bit differential ADC with extra gain and calibration circuitry that makes it perfect for measuring strain gauges / load cells or other sensors that have four wires that are connected in a Wheatstone bridge arrangement.
Traffic Light Conference Badge
Let your fellow convention attendees know how much socialization you're up for with this traffic light badge. A button on the side lets you change the color of the traffic light on the fly.
How To Install Drivers for WCH CH9102F USB to Serial Chips
Certain boards, like the ESP32 Feather V2, have a USB to serial converter chip that communicates between the processor and your computer. This guide will show you how to install the driver needed for the WCH USB to serial chips.
Wireless LED Maracas
Build maracas with wireless LEDs! The coil is placed vertically so that the LEDs are always lit. You can build the maracas with plastic baubles or 3D printed parts.
Adafruit CP2104 and CP2102N Friend - USB to Serial Converter
Transfer your every-day serial data from a microcontroller to computer with the Adafruit CP210X Friend. This is a high-quality USB-Serial chip that can upload code at a blistering 2 or 3Mbit/s for fast development time. By default, we've set it up so that it matches our FTDI cables.
MIDI Laser Harp with Time of Flight Distance Sensors
You can build a laser harp using time of flight sensors, a Music Maker FeatherWing and of course, lasers! The time of flight sensors detect when you've "plucked" a laser string and the Music Maker FeatherWing sends out beautiful synthesized instrument sounds.
Adafruit DVI Breakout Board
We designed this little breakout board after seeing some cool demos for the Raspberry Pi Pico driving an HDMI display. This breakout board has no active components on it. It's just a connector you can plug an HDMI/DVI cable into, and 220 ohm series resistors. This is intended to be a 'source' only, great for making demos or just noodling around with digital video generation
Adafruit VL53L4CX Time of Flight Distance Sensor
The Adafruit VL53L4CX Time of Flight Sensor is another great Time of Flight distance sensor from ST in the VL5 series of chips, this one is great for long distances - it goes up to 6 meters compared with 4 meter max of the VL53L1X. This is a 'big sister' of the VL53L4CD ToF sensor and can handle about ~1 to 6000mm of range distance, it also has some ability to do 'multi object detection'.
QT Py RP2040 USB to Serial MIDI Friends
Use a QT Py RP2040 as a USB to Serial MIDI converter. You can build small add-on boards, or BFFs, for TRS-A, TRS-B and DIN-5 MIDI out circuits. The QT Py RP2040 takes in MIDI over USB and then sends the messages out over serial UART.
