There you go!
I do have a favourite manufacturer for pcbs but sometimes its smart to check out the other fabs. I’ll test some manufacturers and write short reviews about them – this time: Seeed Studio Fusion – https://www.seeedstudio.com/fusion_pcb.html
I plan to do something with Nixies in the future but wanted to use a modern driver. After a bit of searching I found this awesome project: https://github.com/dekuNukem/exixe
Damn impressive and even open source! Since pictures are worth a thousand words have a look for the driver pcbs:
The edge cuts are clean, no frizzing at all. That’s pretty nice. Unfortunatly Seed puts a production code on the silkcreen. Meh, I really don’t like that.
Looking very closely you’re able to spot the marks of the e-test probes. Pretty impressive, I’ve never seen them before. I wasn’t even sure if my fab does this test.
Following up are some detail shots. The boards are good, but I spotted a small error at the end. Have a look for yourself:
The drills are all centered, the silkscreen seems to be offset by a bit though. Bummer.
The error is – excuse the pun – microscopic and won’t affect the functionality.
I know it sounds weird, but it’s a bummer you get exactly the amount of pcbs you order.
if you don’t order pcbs often this will most probably sounds weird. But usually you get at least one spare pcb. I like to use them for fitting tests or if something goes wrong while assembling.
Well, thats probably complaining at a high level.
Ah, what’s also pretty nice at Seed is the opportunity to order flex pcbs directly and having your boards plated with hard gold. That’s quite impressive, my fab won’t do that.

My RAM expansion for the Amiga 600 broke 🙁 Instead of getting an old and used one I decided to have a look if there are any affordable new expensions out there.
Unfortunatly, the cheap expensions got no RTC, that seems to be a feature of the expensive cards. Well OK, I’ll make my own then.

Someone asked my about a scan of the dummy insert for the famicom disk system to protect its drive from dust. The rar file below contains a high res scan of the insert, the *.psd-files are ready to print. The thickness of the insert is about 1.9mm.
Just click the image to download the files:
This one was particulary nasty – it was glued shut and the pcb was as glued into place. Instead of a label somehow put white adhesive tape around it and labeled it “preem”. No idea what that means.
Edit: @Hafenheld_Max from twitter guessed the sticker show the logo of the Swedish company Preem Petroleum AB. And well, that seems to be right, thanks Max!
