Hi all. I've mentioned in a few threads about a project created by Keir Fraser, the same developer who created Flashfloppy (an open source firmware for the Gotek USB Floppy drive) and that is Greaseweasel. Basically it allows you to access a floppy drive at the flux level using a USB interface which then allows you to read/write many different formats all on a standard PC floppy drive. You can read more about it below. https://github.com/keirf/Greaseweazle https://www.facebook.com/groups/greaseweazle/ The purpose of this thread is that I thought I would let the wider retro OCAU know about this and also let people know that I am doing a limited run of interface PCB's which I'm making available here. Basically what the interface PCB does is turn the mess of cables between the STM32 Blue Pill into a nice and neat solution like below (not my photos). https://github.com/keirf/PCB-Projects/tree/master/greaseweazle It should be noted that this is just the first revision of the Greaseweasel and the developer is currently in the process of creating an all in one solution which uses the STM32F7 vs the current STM32F1. But he has assured the firmware will be compatible with both so development will continue. What I will supply: Currently I'm awaiting the arrival of 6 PCB's (one for myself making 5 available) which I've ordered from OSHpark and is currently on it's way via snail mail. I'm also getting together a few of the other little parts required such as the floppy header so I'll include: Greaseweazel PCB Interface 34 Pin Floppy Header Floppy Power Header* Molex to floppy power adapter 4 x 0805 1k SMD Resistors** 1 x 0805 1.5k SMD Resistor** 40 pin DIP socket * It should be noted that not all 3.5" floppy drives are capable of running on just 5 volts supplied by the USB and may require an external power source. I've ordered one of these for myself and I'll include a molex to floppy adapter as seen here if you plan to do this. I had plenty of them spare at work so they didn't cost anything. Personally I would recommend going down this route. 5.25" Floppy Drives will require external power. ** I'll throw in a couple of spare SMD resistors to allow for errors. Also it should be noted that the 1.5K Resistor is not needed if your Blue Pill has the same resistor at R10 on the PCB. Not all Blue Pills out there have the correct resistor installed. What you will need: STM32 "Blue Pill" * USB to TLL Adapter (for the intial programming) Floppy Drive 12V/5V 2A Molex Power Supply Adapter (optional but recommended) * Like it seems with everything these days, be on the lookout for fake STM32's which use a Chinese clone of the STM32F103C8 chip. There is a guide here on what to look for. I brought mine from this seller which while is probably a Chinese clone of the Blue Pill (others have found the same one on AliExpress), it uses the correct chip and has the 1.5K resistor at R10. Cost: I'm not planning on making any money on this just looking to offload what I don't need which in turn makes it cheaper for you and me. All up it should be $20.00 including postage. To give you an idea of savings just the making of the 6 x PCB's (mininum order) alone cost me about $31 after conversion from USD, then you've got to add all the other bits and pieces which often have minimum order quantities too. Let me know if you are interested, first in first serve. Once these are gone that's it! If all goes to plan hopefully these will arrive in time for me to ship them all out to arrive before Christmas as I think they will be a cool little project to do over the Christmas/New Year break. I think that's just about everything, let me know if you have any questions or if I've missed anything. But again, check out the Facebook page as there are a lot of very knowledgable guys on there who usually respond very quickly to questions.
