low cost and easily available floppy interface hardware, part 9! pico power

time to wrap up today's hacking! we had a goal of finishing today with a raspberry pi pico board being able to read out flux off a floppy disk, and here we are: this is a ultra-low cost dev board, only $4 and 15K in stock at Digi-Key https://www.digikey.com/short/f2d841fn - a little soldering is required to attach header but the wiring is straight forward: start at GP2 and connect all the pins thru to GP14 in a row, skipping over the ground pads (dont forget to connect one of the grounds of course) we just tested dumping our 1.44 HD diskette just fine. in the next week we'll try to add flux writing support (we've only done reading so far), trying out HFS DD (so we can image @anildash's prince floppy), completing a PR to greaseweazle and maybe trying out the disk ii connection. a great way to kick off 2022, happy new year! #adafruit #raspberrypi #rp2040 Cross-platform interfacing hardware for floppy disks, part 8 - PINK TIME! https://youtu.be/OpAN5FSmPBw https://blog.adafruit.com/2022/01/01/cross-platform-interfacing-hardware-for-floppy-disks-part-8-pink-time/ YAY! floppy disk interfacing part 7, a floppy flux milestone! https://blog.adafruit.com/2022/01/01/yay-floppy-disk-interfacing-part6-a-floppy-flux-milestone/ https://youtu.be/IrSwMuFk-2c reading floppy disk data part 6, MFM sector decoding https://youtu.be/mE-77nEXbGc https://blog.adafruit.com/2022/01/01/reading-floppy-disk-data-part-6-mfm-sector-decoding/ reading raw floppy disk data part 5, at night the greaseweazles come https://blog.adafruit.com/2022/01/01/reading-raw-floppy-disk-data-part-5-at-night-the-greaseweazles-come/ https://youtu.be/e6v7Q4h5JBM interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 Adafruit Floppy is a project to make a flexible, full-stack, open source hardware/software device for reading, archiving, accessing and duplicating floppy disk media. It joins a family of open source hardware and software such as greaseweazle and fluxengine, and will attempt to increase the availability and accessibility of floppy disk controllers by: porting the greaseweazle / fluxengine firmware to Arduino so that it is less tied to specific hardware, adding firmware support for the RP2040 chip / low cost pico, adding hardware support for reading apple ii disks including index sensing, adding woz/a2r support to greaseweazle / fluxengine, and investigating analog flux data acquisition methods for repair of damaged disks. all of this with permissively licensed hardware and software so folks can re-create without licensing agreements, NDAs, or discussion. https://github.com/adafruit/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/ -----------------------------------------
