LED Matrix Alarm Clock
Build and IoT alarm clock using CircuitPython with sound effects, brightness dimming for night time and cute animations like winking eyes.
Adafruit SEN6x Breakout
Now you can quickly integrate the Sensirion SEN6x environmental sensor node into your microcontroller or microcomputer project, with no soldering or fiddly breadboarding - thanks to this here Adafruit SEN6x Adapter Breakout (for SEN66 and friends). We covered the awesome Sensirion SEN66 environmental sensor nodes on EYE ON NPI a while ago; it's an awesome all-in-one air quality sensor, but it has the annoyance that it requires 3V power/logic, and it has a special cable connection.
"Mother of all Demos" USB Keyset
Build a custom USB HID device that works like a chording keyset using an Adafruit QT Py RP2040 and coded in CircuitPython.
Adafruit Sparkle Motion Stick
The Adafruit Sparkle Motion Stick is part of our series of "Sparkle Motion" boards, which are our attempt to make the best small WLED-friendly smart LED driving board in the whole world. The USB Stick version of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion. It even fits into a low cost off-the-shelf case for protection. It can be powered via USB Type A for up to 5V 2A input - you can use off-the-shelf USB battery packs for portable operation.
Solderless Robot Toy Xylophone
Robot instrument builds are always fun, but the wiring can be cumbersome. However, this robot friend, built around a toy piano xylophone, requires zero soldering. It runs CircuitPython code on a Metro RP2350 with an I2C to 8 Channel Solenoid Driver breakout connected with a STEMMA QT cable.
Motorized Camera Slider 2-Axis
Build a motorized camera slider that can pan and slide, creating professional looking effects.
Adafruit I2C to 8 Channel Solenoid Driver
We designed the Adafruit I2C to 8 Channel Solenoid Driver featuring an MCP23017 GPIO expander to make using up to eight solenoids easy and solder-free. Power the solenoids with a DC power supply, 3V to 24V DC maximum. Each solenoid has its own pass transistor AO3406 N-Channel MOSFET. A red LED will light up to let you know that the transistor is on.
Adafruit TLV320DAC3100 I2S DAC
We really love the sounds coming out of the Adafruit TLV320DAC3100 I2S DAC with Stereo Headphone and Mono Speaker output - it's got clean, excellent-quality, stereo audio that can connect directly to your 16 ohm headphones and/or a 4 ohm - 8 ohm speaker. This makes it excellent for all-in-one audio projects without needing an external amplifier.
Asteroid Tracker
Build an internet-connected asteroid tracker. This tracker displays the asteroid name, date, predicted distance from the moon, predicted distance from earth and impact percentage.
USB to Eurorack Power Supply
When the TPS65131 Split Power Supply breakout was added to the shop I thought one thing: Eurorack! Eurorack synthesizers use +12V and -12V for their power input. This can be tricky to accomplish with the usual DIY tools at our disposal, thus this project: a simple 5V USB to standard 10-pin Eurorack power supply. Perfect for quickly testing a module or using a module outside of a usual rack setup.
Severence-Inspired Lumon Bluetooth Speaker
Make a Bluetooth speaker with an ESP32 Feather, I2S amplifier, speaker and 3D printed case inspired by TV show Severance.
IoT Moon Phase Guide
Build an LED Moon Phase clock that updates throughout the cycle!
Adafruit TPS65131 Split Power Supply Boost Converter
Need those tricky split-rail voltages for your vintage electronics? The Adafruit TPS65131 Split Rail Boost Converter generates both positive and negative voltage rails from a single 3-5V input. This makes it great for mimicking or replacing a transformer-based power supply or something that needs negative bias. We kept the design compact, and it even has adjustable output pots, so you can tune the voltages from about +6~+15VDC and -6~15VDC.
Adafruit PCM510x I2S DAC
We stock a lot of chips and development boards that are able to do high quality digital I2S out, which makes for great quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real time. However, we don't have a good selection of I2S DAC boards...until now! We really love the sounds coming out of the Adafruit PCM5102 I2S DAC with Line Level Output - it's got clean, excellent-quality, stereo audio and does not need any MCLK or I2C configuration. Literally just pipe some I2S audio in and it ill just work.
Severance Portable Macrodata Refinement Terminal
This project is built around a Raspberry Pi 5 running Python code inspired by the Macrodata Refinement program in the TV show Severance. A DRV2605L breakout vibrates a small haptic motor as your cursor gets closer to the intimidating numbers on the screen. A Raspberry Pi Touch Display 2 is used for the screen.
