I've recently been playing with the Gotek floppy emulator, and found its complete silence a bit disconcerting - so I came up with a modification to add head-stepping clicks using a piezo sounder.
Here's a prototype in operation: https://www.youtube.com/watch?v=e-nhcgALcDE

I have three units for sale (in black), with the sound modification done and the programming headers added. Please note: in accordance with the wishes of the developer of the Amiga-compatible firmware, these drives are no longer supplied pre-flashed. You wlil need to upload the firmware file yourself using a suitable USB-TTL adapter.

More units are on order so please declare interest here if you'd like one.
Batch 1
Payment received from Damon1971 - unit dispatched

Deal complete with Z3Spacial - feedback left
Payment received from Friend_plus - unit dispatched


Batch 2 - drives received, awaiting modification / flashing.
In line
* BrooksterMax (black) - payment received
* Manic23 (white) - feedback left
* Snoozy (white) - unit dispatched
* DonAmiga(white) - feeback left
* Kitman (white) - unit dispatched
* Drutt (white) - feedback left
* GaryBensel (Black) - unit dispatched
* Holzroller (white) - feedback left
* Z3Spacial (white) - unit dispatched
* Thanius (white) - Interest withdrawn for the time being
* Matu75 (white) - Interest withdrawn

Batch 3
Lord (Black) - payment received
Gede (White) - payment received

Juri (potentially interested in future)
Srashak (White) - payment received
...

(For anyone unaware of how to use this, you need a USB flash drive containing the selector.adf file from the firmware archive found on this page: http://cortexamigafloppydrive.wordpress.com - and also ADFs of the disks you want to emulate.)

Asking £30 each unit, buyer to pay postage and PayPal fees.

I shall do some more in the near future, so if you want one declare interest here, and say which colour you'd prefer (black or white).

Please note: in the first batch, I wired the piezo sounder to the 12v pin on the Gotek unit. This works fine when the drive's in an actual Amiga, but it turns out most external enclosures don't bother connecting that pin, so the sound mod in batch 1 doesn't work in external units.
For batch 2 I will wire the sounder to the 5v pin instead (at the cost of a little volume)
I also discovered another quirk of the sound modification: because there's no drive select circuitry on the sounder, the drive sounds happen when any floppy drive attached to the system is accessed, not just the Gotek unit!

have you any of these in white?

Not yet, but I can always order some. They don't arrive quickly, however!

Yes, certainly - if anyone wants an existing drive modded I'll do them for £13.50, buyer to pay postage both ways and PayPal fees.
(Also happy to flash at the same time, of course :) )

Sending PMs to Damon and liam1101...
 
Sorry to derail this a bit, but is this sound mod available anywhere for download, for those who get their hands dirty with modifications and stuff? Really cool stuff!

Yes indeedy - have a look here if you want to roll up your sleeves and have a go yourself :) http://retroramblings.net/?p=777
(Watch out, the photo shows a 2N7000 even though the schematic says BS270 - the latter would be flat-side-down, not flat-side-up as shown in the photo.)

(Adding DonAmiga to The List :) )
