say hello to the super duper floppy flooper

Superduperfloppyflooper schem

we are gonna be flip-floppin between 34-pin IDC and 26-pin FPC floppys so what we really need to get made is a ‘flooper’ – ok so we just made that up but basically something that will let us connect to either types (or adapt between the two) while performing a level shifting so we can use our fast 3V logic chips. here’s a rough draft, with one 74AHCT245 logic shifter in and one shifter out. for the open drains, we’ll just pull them up with 2.2K resistors. while working on projects we often sketch out pcbs for fast turn, as needed – this will turn into some other board in the end most likely, but it’s published over at under an Unlicense while we wait for PCBs to arrive … hopefully by then the software will be done 🙂

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. bread’s expired? I couldn’t… resist.
    Ohm my goodness…
    Step it.

  2. What uses FPC for floppy drives? I searched and only found an embroidery machine and maybe and old Toshiba laptop, so I’m guessing my Google-fu isn’t awake yet at 5 AM. 😉👍

  3. My Yamaha SY-85 synthesizer uses the same kind of floppy as industrial textile machines. Except it is 720k. There is a different pin/detection circuitry for floppy loaded or unloaded detection, which is integral to the function of the synthesizer when loading large banks of samples. So far I have been unable to get USB 720k emulators to work because of the load unload detection problem.
