Good to see that people keep building the sync adapters. I can confirm that I am not aware of anyone else building these at the moment. Props for doing it!

Best wishes,

I haven't heard any news about it either. In the meantime I built the original sync adapter which has been working great. I will be making a couple more of them soon so send me a DM if you would be interested.

Any news on the completion of the interface?

That looks great and nice with the smaller design.

I'm also interested in buying one and got a working setup if you would need more testers. Located in Estonia.

I'll DM you! Refreshing won't be easy, you need an avr ISP programmer and a little adapter jig I use or to solder some wires to some pads. Earlier I thought reflashing with Arduino IDE would be possible but realize now that it won't.

Cool! I'd be happy to test it, but I live in Sweden.

I'm the author of defMON though, so perhaps that could help in case some bug fixing would turn out to be needed.

What is needed to reflash? Usb-c cable and the arduino IDE, or something else?

Here's the interface:

I'm working on the code (porting to Arduino/MiniCore). Source available here: https://github.com/catskull/defmon-sync

I have a c64 but not a working defmon setup. Anyone up for testing? I can send you an interface for free. Ideally US based and technical enough to reflash the board.

Damn, that is a sick device. Thanks for the tip.

sidfx.dk for anyone interested in a nice two sid solution with lots of sound options

i personally have a sidfx so everything is protected by that board. good looks tho. lemon64 is a wealth of information

OK, so there are no conflicts.
On another note, I just came across some ESD protection boards that piggy-back the controller ports. A suggestion for you to protect your SIDs:

serial port is used for data and power comes from the cassette port.

edit: confusing my port names

Does SD2IEC simply use the user port for power or something else?
I wonder if a 1-to-2 User Port Splitter add-on would be a good option. The majority of user will likely be using a floppy drive emulator as opposed to an official one.

would you consider adding an additional user port input to the device? this way one would still be able to use sd2iec or similar devices in parallel with the midi sync.

I think we'll go ahead and get some modern interface put together. Should be small and about the same price as scannerboy used to sell them for. I'll update here with any news!
