Newxie brings the joy of nixies without the 170V power supply 💡🕰️✨

If there's one thing that melts our hearts, it's a nixie clock - we built one 20 years ago! (https://www.ladyada.net/portfolio/2003/index.html) but nixies are hard to find now that we don't hit up the MIT swapfest at 7am anymore (https://calendar.mit.edu/event/swapfest-the-flea-at-mit-2024); well we saw this funky faux nixie clock

🖥️ 🧸 a new (old) approach for 21st-century kids using computers... chronological order

as our kiddo gets older we are going on a journey with her, focusing on the evolution of computing from where it started, and using each one, in order.

our adventure begins with retrofitting a 1998 littletikes/ibm playset to house the early computers, providing her with a tangible way to interact with these machines.

A level shifter just for pixels 🔌✨💡

After noodling with some WS2811s and TM1814, we really wish we had a board that would level-shift our NeoPixel signals from 3V to 5V or give us an inverted data line. So, we designed this board. it uses an AP3602 (https://www.digikey.com/en/products/detail/diodes-incorporated/AP3602AKTR-G1/5305823) charge pump to give a clean 5V reference voltage from 3~5V. a 74HCT2G34 (https://www.digikey.com/en/products/detail/nexperia-usa-inc/74HCT2G34GW-125/1300830) shifts two signals - we call them DAT and CLK, but it could be anything really - to 5V from 1.8~5V.

Working on some photos and videos from our ribbon cutting event for the new Adafruit factory in Industry City, Brooklyn, NY - USA! Here's a preview! 🎀✂️🏭🗽🇺🇸 Special thanks to the President of the Brooklyn Chamber of Commerce, the Managing Director of Industry City, and the Vice President of Partnerships at the NYC EDC! More soon, it's Sunday after a loooong week and we are zonked!

A lipo charger with a buck built-in

We often have projects that want to run off a lipo, but you need an external regulator to handle the conversion from 3.7~4.2V down to 3.3V. This little board will do the job for you: it has USB Type C power and a 500mA charger chip for standard 1-cell poly/liion cells. a TLV62569 3.3V buck converter will give you a nice 3.3V output (https://www.adafruit.com/product/4711) at up to 1A max without worrying about heat or LDO power lossage.

Petite Pico Probe is Perfect for Parlaying with a Pi Penta

if you got a Pi 5 (https://www.adafruit.com/product/5812) and you want to log in or debug without ssh'ing or using a monitor and keyboard - there's now a super fast and easy way to get into the UART console - thanks to the new JST SH 3-pin 'UART' port nestled between the HDMI connectors.

Use your Pico Probe (https://www.adafruit.com/product/5699) and connect the 3-pin cable to the 'U' port - the probe board will appear as a COM/serial port, and you can open it up with any terminal program. we love using it for kernel debugging because the connection stays open between reboots and you'll get all messages directly printed, plus the early boot messages...even ones before the firmware is loaded or the display comes up.

PCB of the Day! The VCNL4200 has long-ranging vision 🔍🤖🛠️

The VCNL4200 proximity sensor https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VCNL4200/7394601 , which we found on last weeks The Great Search https://www.youtube.com/watch?v=xZBgRGVrHO0 , can detect motion up to 1.5 meters away, and has an I2C interface that makes it an excellent match for a Stemma QT board prototype. Which is what we've got here! Note the IR LED requires an external P FET to drive it!

PCB of the Day! AD5693 16-Bit DAC QT 🔌📈🔋

Single-channel, 16-bit buffered voltage outputs, and has a 2.5 V internal reference. Operates from 2.7 V to 5.5 V, ensure zero scale at power-up, and offer a power-down mode with reduced current consumption.

PCB of the day! SGP40 Air Quality Sensor Breakout - VOC Index - STEMMA QT / Qwiic 👃🥛🌬️

*sniff* *sniff* ... do you smell that? You no longer need to stick your nose into a carton of milk; you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is an excellent air quality sensor from the sensor experts at Sensirion, with I2C interfacing, so you don't have to manage the heater and analog reading of a MOX sensor.

It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals.

Matrix Portal S3 skips over the unobtainium SAMD51 🔌🔧💡

There's nothing like hefting a brand new panel of PCBs, ready to be snapped-apart and tested! this board is a refresh of our Matrix Portal M4 board - SAMD51's are unavailable for the near future so it's a great excuse to do a redesign...here we've got an 8MB Flash + 2MB PSRAM S3 with wifi, bluetooth, and a parallel-driving peripheral that does a great job driving RGB LED Matrices.
