We’ve got so much happening here at Adafruit that it’s not always easy to keep up! Don’t fret, we’ve got you covered. Each week we’ll be posting a handy round-up of what we’ve been up to, ranging from learn guides to blog articles, videos, and more.


Timeslapse rework – VL53L1X to VL53L4CD QT breakout

One nice thing about standardizing on Stemma QT is that it makes it super easy to swap chips out when new versions appear. Here we are reworking a VL53 breakout to remove the older chip and replace it with a VL53L4CD which is a new time of flight sensor from ST. this one has lower range, only up to 1.3 meters instead of 4 meters BUT it can do much closer reads, as little as 1mm away, so it could be useful in some situations where the sensor could bump up against what it is trying to sense – video.

Rotary Phone Dial Keypad

Build a retro input device that types the numbers you dial

The rotary phone dial is the pinnacle of user interface for satisfying, slow number entry! Originally designed for dialing phone numbers, you can now re-purpose this beautiful piece of machinery as a USB number pad to use with your computer or mobile device.

With the KB2040 Kee Boar and a bit of CircuitPython code, you can read the mechanical dial pulses and convert them to USB HID number key messages. You can also modify the code to type letters, or go even further and make your phone send MIDI messages.
