Following the first prototype of the LM1881 based SyncFix64 I made a few minor changes, improving the schematics and layout. Then I was ready to order the first batch of properly manufactured PCBs. The boards took a little over two weeks for production and shipping.
This was also my first try at ordering a v-cut PCB panel and I’m quite satisfied with the result considering the resulting low price per unit. I assembled one of the boards tonight and the device is working properly. So I assume the whole batch should be fine.
The project files for the updated version 1.1 of the SyncFix64 are available on Github and here is the list of required components:
| C1,C2,C3 | 0805 | 100n |
| Q1,Q2 | SOT-23 | BSS138 |
| R1 | 0805 | 100r |
| R2 | 0805 | 680k |
| R3 | 0805 | 10k |
| U1 | SOIC-8 | LM1881 |
| U2 | SOT-223-3 | AMS1117-50 |
| C4,C5 | 1206 | 22µF |
Update: There are German assembly instructions available for download now.
Hi do you possibly sell the pcb or a kit of this, I am facing the same problem.
I have a few kits left over and some more PCBs. Please send me an email if you are still interested. Shipping costs might be an issue though, depending on where you are from.
I have received your email but I could not reply because Hotmail has (wrongfully) blacklisted my mail server. I have requested to be removed from the blacklist but that will take time. Alternatively, if you have another (non-Microsoft) email account you could email me again. Sorry about that.
