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 generate some pretty serious static. we used our scope (earthed) ground to dissapate as much as we could, and were wary to make sure the plastic, and us, didn't touch any components. whew! we'll start poking at this shortly. https://maceffects.com/products/clear-case-for-apple-disk-ii-5-25-floppy-drive #adafruit #apple #clear Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

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 power supply and controlling technique is going to be different for this drive because to save costs they removed and simplified the drive control system. The Great Search - Positive to negative 12V power inverter for Apple 2 disk drive bias. https://www.digikey.com/short/5w04zzr2 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 driver chip to find a charge pump converter! #deskofladyada #thegreatsearch #adafruit Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

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 working on it! #adafruit #floppy #retro Archon / Archon II / Archon III compilation on archive.org: https://archive.org/details/Compilation_Archon_Archon_II_Archon_III_Asterix_19xx_- Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

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 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. Aaand, everyone always asks, so!

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 the SPS30 particulate sensor (https://www.digikey.com/en/products/detail/sensirion-ag/SPS30/9598990), but combines additional sensors inside! There's a few models planned for the SEN5X series - today we're highlighting the SEN54 which has * Particulate Matter - PM2.5 * Humidity and Temperature via SHT40 (https://www.digikey.com/en/products/detail/sensirion-ag/SHT40-AD1B-R3/14322709) * Volatile Organic Compound via SGP41 (https://www.digikey.com/en/products/detail/sensirion-ag/SGP41-D-R4/15652788) (There's also a SEN55 which will include an addition NOx sensor, but it has not been released yet) The sensor uses a sub-processor that will act as a single I2C peripheral to receive commands and send sensor data back. It's a great deal if you want a simple-to-install air quality sensor with all the goodies. There's a 3D model available for mechanical installation, and for connectivity you just need a single JST GHR 6 pin (https://www.digikey.com/en/products/detail/jst-sales-america-inc/GHR-06V-S/807818) cable which has power, and I2C or UART data. Note that the cable is not sold separately so you'll need to acquire the cable from a separate vendor or pick up the full evaluation kit that comes with a couple cables at additional cost. (https://www.digikey.com/en/products/detail/sensirion-ag/SEK-SEN5X/15903862) The real success story here is the libraries that are pre-written and supported by Sensirion that makes getting started very very fast. We were able to wire up the SEN54 to an ESP32 board and run the BLE demo (https://github.com/Sensirion/arduino-ble-gadget) within a few minutes! Using the Sensirion MyAmbience app, (https://apps.apple.com/us/app/sensirion-myambience/id1529131572) we could see instant data show up on our iOS or Android device. Over-all a slick and easy experience. We must say that we're really impressed with how maker-engineer friendly the sensors and firmware development is. This all-in-one sensor board is going to be a popular environmental sensor from folks who really know environmental sensing! Digi-Key has a whole bunch of the Sensirion SEN54 sensors in stock right now for immediate shipment (https://www.digikey.com/short/pn08ff2w) and with same-day shipping, you can order today and be sensing by tomorrow afternoon!

Let's archive all those old mac floppies, starting with this 1984 biz sim game! OK we're making slow but steady progress - now that we've refactored Adafruit Floppy to better handle looooong pulses, identified the best drive for reading mac GCR diskettes, and tested fluxengine's new .dsk format support, we can start reading and archiving mac 400k/800k disk images. first up is this very old, nicely made game called "Make Millions" https://en.wikipedia.org/wiki/Make_Millions by Tom Snyder https://en.wikipedia.org/wiki/Soup2Nuts who not only wrote games but also developed Dr Katz Professional Therapist https://en.wikipedia.org/wiki/Dr._Katz,_Professional_Therapist Anyways, wanna play it? we've upload it to the internet archive and by setting a few metadata flags it launches in PCE.js for instant playback in the browser! https://archive.org/details/make-millions-tom-snyder #millions #adafruit #floppy Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

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 MPF but a few other drives were able to read with 10+ (!) retries. The timer refactor didn't seem to make much difference on the GCR decoding but it seemed like the right thing to do and there's less fudge-factor dependancies on the cpu clock frequency. Also, FLOPPY SOCKS! #adafruit #floppy #retro Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

In order for our floppy accessing project to connect to laptop-style drives, we will need to source FPC (flex printed circuit board PCB) cables that fit the existing drives and can snake on over to our PCB. Unlike most display FPC's, these need to be 1mm pitch, and we need to watch out for whether they are A-A or A-B style. Thankfully Digi-Key stocks every length, style and pitch of FPCs you could possibly want. So let's find it and we'll order it for our prototype testing this week!

ok getting back to our floppy project (after we did a bunch of hardware designs last week, stay tuned for some exciting new products!) here's a USB floppy drive that we will use our 'flooper board to turn from a 26-pin FPC into a 34-pin IDC. and...it works! it's a straight conversion, just needs the mechanical adaptation here, and you can use these common USB floppy drives as an everyday standard magnetic-flux device. here we're reading an IBM MFM floppy. the samsung 321 can read mac 800ks, but the teac fb-05 is not as happy with those pulses! #adafruit #floppy #flooper Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

the industrious adafruit.io team did a massive refactor of the way we support i2c sensors in wippersnapper to allow automatic generation of new sensor devices without having to hardcode how they look and are treated in the backend (and dontcha know, we even made the repo where we are keeping all that metadata public over at https://github.com/adafruit/Wippersnapper_Components/tree/main/components/i2c) and to celebrate, we added TWO more sensors - not only the AHT20 but also the DPS310 and ultra-popular BME280. here we show just how fast it is to set up data logging to adafruit.io with NO code, NO soldering, NO command line and NO toolchain. plug in the bme280 sensor in the qt py s2, open up wippersnapper, check the i2c address appeared, then connect to the new device and select which sub-sensors you want to log into a feed. boom, all in one tiktok minute! more plug-n-play i2c sensors coming soon... #adafruitio #adafruit #bme280 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

ok cats and kittens, we know you missed the floppy hackin' so you should be glad to know we're BACK on the floppy kick, with some timer driven code for capturing and generating flux pulses. we're not 100% sure we need timers to do it but we were having a few issues with writing floppies consistently so figured this could help. today we wrote an ibm mfm floppy and then read it on another floppy drive connected to our computer. being able to write floppy disks also means we may be able to categorize disk drives better since we can test writing and reading pulses. we also put together one of our 'Floopers in order to properly test a laptop drive - successfully! finally, we saw this nifty cut-tape-removal tool on twitter https://twitter.com/dannymodules/status/1490248252465184771 and we're going to try jlcpcb's 3d printing service to get a couple made since they seem super handy The Great Search - 26 pin 1mm FPC cable for laptop floppy drive https://www.digikey.com/short/vbzqw277 In order for our floppy accessing project to connect to laptop-style drives, we will need to source FPC (flex pcb) cables that fit the existing drives and can snake on over to our PCB. Unlike most display FPC's, these need to be 1mm pitch, and we need to watch out for whether they are A-A or A-B style. Thankfully Digi-Key stocks every length, style and pitch of FPCs you could possibly want. So let's find it and we'll order it for our prototype testing this week! #deskofladyada #thegreatsearch #adafruit Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week's EYE ON NPI will be your loyal friend like a pet dog - it's Authentrend FIDO2 Biometric Security Keys (https://www.digikey.com/en/product-highlight/a/authentrend/fido-biometric-security-keys). These FIDO2 compatible USB dongles have an absolutely adorable built-in fingerprint sensor on the end, which means they have an additional layer of security in addition to ownership: you also need to have the matching fingerprints. This is great when you want to secure something with 2 or 3 factors (https://en.wikipedia.org/wiki/Multi-factor_authentication) and possibly without having to have folks remember or change passwords. Historically, authentication was done with just a username and password . But, as we've all learned, usernames and passwords can be guessed or stolen or hacked! Some folks have two-factor time-based code cards (https://www.eff.org/deeplinks/2016/12/how-enable-two-factor-authentication-paypal), apps (https://support.google.com/accounts/answer/1066447?hl=en&co=GENIE.Platform%3DAndroid) or SMS messages which add "something you own" to the list. FIDO/U2F cards have been around as a USB-based authentication system for a bit, and they're slowly gaining traction through an open standard which makes it easy to integrate with web or desktop applications. (https://fidoalliance.org/fido2/) We're huge fans of moving all of your security risk to hardware like these, that abide by open standards - it's very hard to create a secure hardware device. Firmware, storage, even when encrypted, is not often crackable or glitchable (https://blog.securityinnovation.com/glitching-firmware-over-usb-using-facewhisperer). Using an external dongle gives you a hermetically sealed challenge-response system from a company that does only one thing. because the private keys are stored in the hardware, you don't have to store them on device in firmware. These come in a few different mechanical shapes and flavors, including USB A fingerprint key (https://www.digikey.com/en/products/detail/authentrend-technology-inc./ATKEY.PRO-TYPE-A/15761935), USB C fingerprint key (https://www.digikey.com/en/products/detail/authentrend-technology-inc./ATKEY.PRO-TYPE-C/15761936), and a keycard that has NFC, BLE and a USB-A flip-out (https://www.digikey.com/en/products/detail/authentrend-technology-inc./ATKEY.CARD/15761933) We were able to get our fingerprint entered into the dongle using Windows 10's key manager, then used the same dongle to add 3-factor authentication to our Google account. Of course you probably want to use it for non-website projects too! You can interface with the security dongle very easily using the python-fido2 library (https://github.com/Yubico/python-fido2), which means any embedded Linux/single board computer will be able to have trusted authentication added with USB. This could be a very inexpensive and fast way to add trusted authentication for your product without having to hire a cryptographer. There are plenty of Authentrend ATKEY.PRO TYPE-A (https://www.digikey.com/short/p3t50d14) in stock at Digi-Key right now, that's the one we've been using the most, but do check out the other variants as well, such as the USB C, if your computer has type C ports (https://www.digikey.com/short/p3t50d14). Order one for each user today, knowing that the FIDO2 standard will mean easy and trustworthy deployment for many years! See more at https://www.youtube.com/watch?v=11UfySDn7_I

Luxuriously Long Stemma QT cable samples! I2C was never meant to go 200, 300 or 400mm but we laugh in the face of death thanks to these samples we got of some looooooooong stemma qt cables. each cable has two JST SH connectors on either end and a PVC sheathed center. we were inspired by this tweet https://twitter.com/lovyan03/status/1480867328783163396 about I2C wire interleaving with power in order to avoid cross-talk for long cables (I2C is not differential so you definitely do not want to use twisted wires!) if you look closely, the cable is flat and has the red power wire between SDA and SCL instead of having them next to each other. we're just trying it out here with our fancy new ESP32 Feather V2 which has an onboard STEMMA QT connector. #adafruit #stemma #cables Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Adafruit's Limor "Ladyada" Fried and Phillip Torrone will host the Hack Chat on Wednesday, February 2 at noon Pacific / 3pm Eastern. https://hackaday.io/event/183426-floppy-interfacing-hack-chat-with-adafruit When a tiny fleck of plastic-covered silicon can provide enough capacity to store a fair percentage of humanity's collected knowledge, it may seem like a waste of time to be fooling around with archaic storage technology like floppy disks. With several orders of magnitude less storage capacity than something like even the cheapest SD card or thumb drive, and access speeds that clock in somewhere between cold molasses and horse and buggy, floppy drives really don't seem like they have any place on the modern hacker's bench. Or do they? Learning the ins and out of interfacing floppy drives with modern microcontrollers is at least an exercise in hardware hacking that can pay dividends in other projects. A floppy drive is, after all, a pretty complex little device, filled with electromechanical goodies that need to be controlled in a microcontroller environment. And teasing data from a stream of magnetic flux changes ends up needing some neat hacks that might just serve you well down the line. So don't dismiss the humble floppy drive as a source for hacking possibilities. The folks at Adafruit sure haven't, as they've been working diligently to get native floppy disk support built right into CircuitPython. To walk us through how they got where they are now, Ladyada and PT will drop by the Hack Chat. Be sure to come with your burning questions on flux transitions, MFM decoding, interface timing issues, and other arcana of spinning rust drives.

To show and share a project at 7:30pm Eastern today, view the chat or in discord https://adafru.it/discord and look for the JOIN link to join. For best results, be on a wired network connection, and use a headset and microphone.

This weekend we got to play with a VFD tube. This ancient technology uses a gas tube to light up segments. In order to activate the fluorescence, we need to provide 20 to 30V DC on the segments. Not a lot of current, maybe 1mA each, but definitely needs to be a high voltage. For lower voltages, we could use a switched-cap converter. But for this, we'll need a proper booster! Let's find a small, low cost, simple, and available boost converter that can give us these bias voltages from 3 or 5V DC input.
