Arduino Amiga Floppy Disk Reader/Writer (V2)

EDIT:
Link to sale thread of newest version of the pcb: https://www.amibay.com/showthread.ph...Firmware-V1-8)

-- I still have the older pcb's available, so keeping this alive for reference and warranty/support --
I designed a PCB for this great Arduino based Amiga floppy disk reader/writer project (GPLv3). And also designed a small 3D printed case for it. I've converted about 1000 non-copy protected Amiga disks to .ADF format with this, so its great for basic reading/writing, but if you happen to have copy-protected and non-standard disks, then KryoFlux is recommended (I also have that one for non-standard disks).

Design is based on:

https://create.arduino.cc/projecthub...iter-v2-239c97

Download link to reader&writer software: http://amiga.robsmithdev.co.uk/ADFReaderWriter24.zip

Included:
- Arduino Pro based Floppydisk Reader/Writer(v2.4) hardware (see first two pictures).
- mini USB cable for PC connection

Not included or optional:
- floppy cable (with +4.5€ I can add it to the delivery)
- normal PC floppy drive
- 5V power adapter (as you can get them from ebay for like 2-3€ (vs shipping charges from Finland increases 10€ for non-letter sizes). Of course if you don't mind 20€ postage to Europe, then I can offer all in one solutions too.


Payment Paypal friends&family or IBAN transfer.

Price: 29€
Priority shipping (not registered) for EU countries: 3.9€
Priority shipping (not registered) for non-EU countries 8€
Exceptions: Not shipping to Mexico.

Update: Howto update earlier V2 version to V2.4 version:

Open v2.4 sketch file with Arduino IDE ( https://www.arduino.cc/en/Main/Software ) and then choose Arduino Pro mini (red square in the picture) and right com port, and then press the arrow (req square in picture) to compile and upload the new version to the board. When IDE says "done uploading" then your all setup with v2.4

Edit: Robert has released v2.5 version of the project, I will make separate sale threat for it as hardware PCB has changed a bit between versions.

If you want to upgrade this older version to Application V2.5, Firmware V1.8, then you need to cut one trace and add 2 jumper wires:

Does this require an Amiga floppy? Or can is use a regular PC 1.44 Disk Drive.

Website says it can use a standard PC Floppy drive. I was going to DIY this at some point but life's too short. :D

So... :interested: - Interested.

Sending PM.

Interested ! :D

Replied payment details to Jaruzel.

Ratteler: regular PC drive

payment and info replied. :)

Received payments from Marco06 and Jaruzel, visiting post office in the morning.

Interested! Sending PM.

Replied with payment details.

Payment sent!

Interested :)

Will PM.

Replied ElectroBlaster with payment details.

Interested!

Replied with payment details to benmatthew.

Payment received from benmatthew.

Received ! thanks ! :)

Item Arrived. Thanks!

Really good build construction - What 3D printer did you use for the case?

Haven't had a chance to use it yet... soon though!

I use multiple 3D printers. I have pimped up Anet A8 (with upgrades its almost as good as Prusa) and Prusa i3 MK2 and soon I'll also have Creality CR-10S (DHL shows package arriving to Finland already so I should have it up and running next week).

Br, Jonni

Received. Many thanks. Certainly looks the part :)

I'm interested!

Replied payment details to FluffyFreak.

After sending to FlyffyFreak my stock is 0 for a while, I'm getting more parts to build more devices during january. I'll keep the post updated.

Payment sent, lucky getting the last one of this batch!

Thanks.

Mailed device to FluffyFreak.

Good, you sell only the pcb board to mount.

jonni, parcel arrived this morning, it looks great :)

Thankyou

Just got parts for building 10 more, so its available again.

Should have updated, the two I ordered arrived. Very impressed with how you made these :D

Interested in one.

Hi, interested in one :)

received payment from a.mi.goun and replied with payment details to Epongette

Interested in one, thanks!

Replied with payment details to jsundh

Payments received from Epongette and jsundh. I'll visit post office tomorrow.

I am interested in one - PM sent

Payment Sent

Payment received from fotbob_gb. Visiting post office monday morning.

Update: All the current orders were shipped this morning.

Arrived safely - Looks very nice & works perfect - Thanks.

Feedback Left :thumbsup:

Interested if still available!

Replied Marchocias with payment details.

Shipped to Marchocias.

I have a question. Does it only read or does it also perfectly write like it was said it would? Because I've build this project twice and it apparently only reads disks.
I've checked the signals with a logic analyzer and it showed that Write gate and Write data signals never are activated longer than a brief 2 us. It never works with Verify ON because it breaks of with a communication error only seconds after start. And with Verify OFF it very quickly steps over the writing to disk process creating useless disks.

I also compared the interface with Nick's ADFcopy that perfectly reads and writes Amiga disks and it showed that there must be something seriously wrong with the writing process of the AmigaFloppy Reader controller adapter.

I've asked Rob and he told me that it probably was the CTS timing signal that caused this. But my logic analyzer screendumps showed that other signals like STEP didn't work either comparing to Nick's correctly working ADFcopy interface.
The thing is that both my Arduino mini pro boards and FTDI rs232/USB adapters didn't work (both brand new!). Because I wanted to make sure I made no error and to rule out that maybe one of the boards was defect.
Only Reading disks works perfectly though!
I also tried to edit Rob's sourcecode .ino file with Visual Studio but version 2010 was too old to be able to edit the file. I therefore only was able to download and use the 1,96MB file. Maybe only the source code is errorfree?
However the not correctly writing bug could also exist in the Windows file that communicates with the USB connection?

Does anyone got any clue?

interested if any still available.

I've written adf disks with it with verify ON without problems. Sometimes I need to write old disks multiple times to get my actual Amiga to read it without errors, but that most likely is more the 30 year old disks problem.

I'm using Arduino Pro mini in the design as the project page says that Uno needs seperate serial breakout board for writing solution to work. But I assume that you have noticed that and also used Pro mini? Maybe you have ttl adapter issue? (I'm using these https://www.ebay.co.uk/itm/FT232RL-U...p/253065338990 ) Or maybe you have issues on external power supply (I'm not using serial adapter to power the arduino as usb port usually has troubles powering floppy drive and arduino at same time (so usb vcc should not be connected if your building own adapter from scratch as that can cause problems)). My design has jumpers for flashing the update firmware with usb vcc vs operating with external power.

Sale for one item agreed and payment sent.

Hi Jonni, I already replied on your quick confirming reply that writing disks also works.

I however could not find my previous answer to your comment so here again my reply.
I used exactly the same FTDI board as that was used by Rob in his article, without any luck in writing Amiga disks.
And using an external power supply for 5V made no difference at all.

Maybe the USB adapters didn't work, so I now ordered those RS232/USB boards you successfully used on eBay.
Thanks!

I can't see if the eBay board you suggested also has a CTS pin? I understand that it will be needed for Rob's project because grounding that pin won't work?

Yes, you can see in the second ebay picture that it it has CTS pin in the same place that in any other board, ie between vcc and gnd. That pin needs to be connected to A2 in arduino.

Interested!
