This is a fingertip-sized 7-segment display, so cute! we're driving it here directly with gpio pins from a qtpy samd21 chip, which, according to the internet is Not Something One Does - you're supposed to use an lcd segment driver or at least a chip with built in peripheral. and we sorta see why - there's a little ghosting from how we're driving the segments, even though we're doing our best to de...

This week @adafruit we’re making a zoetrope inspired art display with edge lit acrylic, CircuitPython and CRICKIT. Prototyping sleeve cases for 5in and 3.5in floppy drives for upcoming adventures in retro tech. The timelapse this week is a lovely multi-part box that’s disguised as a flower. Fancy!

The Apple Disk ][ drive is a converted Shugart drive that has three power supplies: 5V, +12V and -12V. The 5V and 12V are for the motor control. Negative 12V is a bit of a pain to generate, but thankfully the -12V seems to only be used for biasing a trim potentiometer. So, we don't need a lot of current. Still, we do need to generate -12V, let's take inspiration from the classic MAX232 RS232 drive...

we see our QT Py ESP32 pcbs have shipped, so it's time to wrap up this design with a tester. like the esp32-s2 qt py, we're using a raspberry pi to test because its a convenient way to run esptool for uploading data and wpa cli scan, to verify the signal strength: we program the test board with access point code, then check the rssi on the pi side. if we get a good signal we can be confident the a...

Build a zoetrope inspired visual art display with 3D printed parts and Adafruit CRICKIT. Party Parrot Zoetrope Learn Guide https://learn.adafruit.com/party-parrot-zoetrope This creates the illusion of motion by rotating a series of acrylic panels that feature engravings of a single frame of animation. A NeoPxiel illuminates the artwork engraving on the acrylic panels and changes color each frame t...

we're absolutely 😍 over maceffects' clear cases. since we've got our shugart 34 pin floppy hacking well figured out (time for hardware spins!) we can now turn our attention to the Apple Disk ][ which is sort of a 'gutted' shugart drive. what better way to psych ourselves up for this work than to re-skin this disk drive? only thing we recommend being careful of: pulling the plastic wrap off can ge...

We churned through a big pile of testers and new designs this week: two IPS TFT displays with EYESPI connectors, the VL53L4CD time-of-flight sensor, the ESP32 QT Py, an OV2640/OV5640 camera breakout, and the ESP32-C3 QT Py. With a lot of our floppy work done and tested for both SAMD51 and RP2040, it's time to move from shugart 34 pin to Apple Disk ][ which uses a different 20 pin interface. The po...

Over the past weeks, Ladyada and jepler have been learning about floppy flux writing. Here, jepler loads a classic game onto a Commodore SX-64 written using a blank floppy disk and a genuine GreaseWeazel interface board. This method works for non-protected software in .D64 format, and FluxEngine software running on a host computer. Coming soon to Adafruit's own prototype hardware? You bet we're wo...

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 https://www.st.com/en/imaging-and-photonics-solutions/vl53l4cd.html 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 B...

This week's EYE ON NPI is another banger from Sensirion - who has been really rockin' out with great sensors over the last few years - it's the SEN54 Environmental Sensor Node (https://www.digikey.com/en/product-highlight/s/sensirion/sek-sen5x-evaluation-kit), an all-in-one sensor node that combines all of the Sensirion top hits in one. This sensor looks like your everyday dust sensor - just like...

OK we were still having some issues with mac 400k/800k floppies and their weirdly long GCR pulses so we decided to refactor our bitbanging code to use a timer capture peripheral and a pwm waveform generator (bit odd because the period is what changes there, but it is possible with most timer peripherals) We also characterized a pile of floppy drives we had - still best results came from the Sony M...
