#CircuitPython2025 is our annual reflection on the state of CircuitPython. We’d love to hear from you too! See the kick-off post for all of the details. Please post by January 14th and email circuitpython2025@adafruit.com to let us know so we can link to it.

This week, we're designing a 1.8" round TFT PCB with a capacitive touch display. It's got a nice overhanging lip, which means we can mount it flush to a front panel. That means we don't want to have mounting holes on the front. Instead, let's use SMT nuts that pick up and place on and give a strong mounting spot while allowing the TFT to sit flat. DigiKey has many variations; let's check them out!...

For our solenoid driver, we have individual transistors for driving each output, which means that we need to protect them with flyback diodes. The important things we need for a flyback diode are to handle the maximum reverse voltage (30V or so) and be fast—there is a peak current of an amp or so, but it's near-instantaneous, so we're not as worried about continuous current. We'll also need 8, so...

Wrapping up last year with display and LED PCB projects, including GC9A01A round display protos and Sparkle Motion boards. Solenoid driver testing underway, fixing WLED/mic interference. Great Search: Picking SOD-323 flyback diodes for solenoids, balancing specs and cost.

We got the 'big' Sparkle Motion boards (https://www.adafruit.com/product/6100) out to the PCB fab house and now are turning to the mini version. This one doesn't have USB PD or 24V support, but it is very compact and has many niceties that WLED users will enjoy...like built-in ICS-43434 microphone (https://www.adafruit.com/product/6049), however during testing, we discovered that GPIO 9 and 10 wer...

We're rounding the corner with testing our Sparkle Motion (https://www.adafruit.com/product/6100) WLED-compatible board. This time, we're doing the fuse test. we got a lot of requests to include a 5A fuse onboard. Of course, we need to verify that it works as expected. With a chonky 12V 25A power supply and my trusty electronic load, we dial up one amp at a time... note that all PTC fuses have a '...

This chonky neopixel tube is a treat with full, smooth color all the way around - but it's also a real pain to drive, given it requires 24V power. Or at least it would be if we didn't have this Sparkle Motion (https://www.adafruit.com/product/6100) board we are testing! With USB PD support, it's easy to plug the board into a USB C laptop power supply that can provide 20V at up to 5A - even though...

We're rounding the corner with testing our Sparkle Motion (https://www.adafruit.com/product/6100) WLED-compatible board. We're doing the audio-reactive test with the built-in I2S microphone this time. This digital mic will give great audio quality without needing any extra work. If you want an external mic wired far away, there are GPIOs exposed that you can solder to for another I2S connection -...

Every week we'll 3D print designs from the community and showcase slicer settings, use cases and of course, Time-lapses!

We've had some requests for nOOds that can be powered from just one end, especially for decorative purposes, and here are some samples we're checking out! These nOOds use an FPC with two...

Learn how to create a magical light-up dreidel using an induction coil and LEDs in this step-by-step tutorial. Perfect for Hanukkah DIY projects, this dreidel lights up as it spins—no batteries required! Whether you’re into electronics projects, holiday crafts, or just love making fun, interactive toys, this project is a must-try. In this video, we’ll guide you through: ✨ Assembling the induction...

Playing with our new Sparkle Motion board that's coming soon (https://www.adafruit.com/product/6100) we wanted to try driving a large display of LEDs and discovered that once you want to do custom display graphics, WLED is not super great. Instead, you can use the open source and free xLights software (https://xlights.org/) which is completely amazing and has a learning curve like a cliff for the...

Since the latest release of 'piolib' we can do things like drive NeoPixels on any pin on the Raspberry Pi 5 (https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/using-neopixels-on-the-pi-5) which rocks, and means we can tackle the next, more complex, project: driving HUB75 RGB Matrix displays (https://www.adafruit.com/product/5362) these require even MORE timing freakiness: using 10 pins...

We got our WLED-friend PCBs today, and we only made one mistake: the wrong resistor on the 3.3V feedback line. Now that it's fixed, the board seems to work great with the latest version of WLED (https://kno.wled.ge/basics/tutorials/)! we are checking all 4 signal outputs with this handy 256-LED grid that sits on our desk. Next, we will test the onboard IR receiver, USB PD, I2S microphone, extra I/...

We got our WLED-friend PCBs (https://blog.adafruit.com/2024/12/02/leftovers-layout-wled-board-revision-a-completed/) and are testing it with various LED grids. First, we tried out a 16x16 NeoPixel grid that runs on 5V. Since that worked well, we're now onto a much bigger 60 x 60 grid - that's 3,600 LEDs! These are some NeoPixel pebble (https://www.adafruit.com/product/6024) netting samples we're a...

As we organize our new office room, we're looking for good storage solutions for the thousands of components and dev boards we have lying around. We have a mix of small through-hole parts like resistors, LEDs, and switches as well as some small dev boards like QT Py and breakout sensors. Let's see what DigiKey has for our component storage needs, such as a pull-out drawer solution. See the chosen...
