Help Wanted

Post by gammaray » Sat Jan 20, 2018 8:32 pm

My computer crashed and I would to make some progress on a project.

Is anyone willing to make me Gerber files for a very simple PCB?

It is basically a 212 by 25 mm board with zx81 or spectrum bus on it for prototyping. It would fit along rear of spectrum case. Traces would be the standard 23or 25, 1.5mm wide spaced on 2.54 mm centers. The length of trace from rear edge is 17mm. I would manually make the necessary keyways or mounting holes.
Finish what you start. Truth is over the mountaintop or six feet under.

Ask Google for "ZX Spectrum BreadBoard" or "ZX Spectrum Extender" or "ZX-BUS expander".

If you have access to a browser, you can easily create schematic and pcb with https://easyeda.com/ . That's what I use.

Thanks for the suggestions but I have cell phone for a browser and accessing this website. Further I needed 212mm x 25mm with only the Spectrum bus on it.

I plan to prototype further the other areas of the board by drilling through holes with different configurations.

Thanks again.

And again pcbshopper.com is your friend.

You can get them from allpcb.com with free shipping with DHL in 5 days for only $17.95.

If you have trouble getting the gerber files saved on the library pc, and upload them to allpcb.com, you can just order the pcbs directly from easyeda.com for $18.98, but you'll have to wait a month for their arrival.

Don't worry about getting the schematics and gerber files downloaded from easyeda.com. They are stored on your free account, and you can download them to anytime later, when your pc is running again.

Got the Gerber files from EasyEDA. A few issues with online interface came up but not sure how to order from them. May go with McKlaud's suggestion.

Thanks Martin, McKlaud!
