[PCBs IN STOCK] 3.5mm <-> 1/4" converter board

kvitekp · Post by **kvitekp** » Wed Jun 12, 2013 3:57 pm

I was testing the fabÃ¢â‚¬â„¢s ability to handle plated slots and ended up with what looks like a pretty useful tool to convert 1.4″ connections to 3.5mm and back.

Instead of maintaining a bunch of mixed jack conversion cables itÃ¢â‚¬â„¢s now possible to just run regular ones through this tool.

BOM:
6 x 1/4Ã¢â‚¬Â Neutrik NRJ4HF Mouser #550-10284
6 x 3.5mm Switchcraft 35RAPC2AV Mouser #502-35RAPC2AV, Digikey #SC1457-ND

If youÃ¢â‚¬â„¢re interested in buying Jack-o-mix pcb please leave a comment in this thread. The price should not exceed $10 w/o shipping, and the boards will be yellow or red.

If you shifted the position of the jacks, you might be able to put this behind a panel. A bit hard to tell from the pic. Looks too tall for Euro as well, I wonder if 5 jacks instead of 6 would work for 3U.

The board size is 4.22x0.99 inch (107.31x25.07 mm), so it should fit behind Eurorack format panel nicely.

Both 1/4" and 3.5mm connectors are flush to the edge of the pcb so it should be possible to mount it behind a panel.

I'm in for 2 and might offer a Euro panel.

In for at least two! If this isn't fabbed yet...any way to add a pad for the plug tip so peeps with nanners can use this? oh and also one pad for the ground? I'm still in for a few regardless.

I'd take one

Hi, Are those OSH Park boards?

I'd been put off using them again because they say they can't do plated slots! Those look fine to me...

Are you talking about dedicated pads connected to each jack tip and ground?

Yep, these are OSHpark boards with mill layer 46 output on board outline.

I was just thinking, it'd be real easy to wire up passive mults and OR combiners by only populating one side of the board and use the mounting holes for the other jacks to wire it up. handy!

Thanks Peter.

If anyone makes a panel for this I'd be interested in 1.

Thanks.

What happened here?

I'll take 3 when I get paid

Who's doing a panel???

I just requested two PCBs, so I guess I'm doing panels (Euro format).

Drop me a PM if you're interested (all orders will be done through grayscale.info, I just want to get an idea of how much interest there might be).

Email sent for 2 PCB's, PM sent for 2 panels. Thanks!

sempervirent · Post by **sempervirent** » Fri Jul 12, 2013 5:04 pm

Thanks guys. Panels are up for preorder now:
http://grayscale.info/panels/midisizer-jackomix/

Looks like there are about 10 panels claimed thus far, and the PCB run was for 25 boards, so I'll give it a couple of weeks and then order the panels.

I noticed that Neutrik makes several different nuts for this 1/4" jack, I'm showing the round one:

Anybody else up for panels? I need to get about 5 more orders to make it happen.

sammy123 · Post by **sammy123** » Wed Jul 17, 2013 11:51 am

C'mon people. I can't afford 5 more.

Panels look great! I just can't bring myself to spend $50 on panels for modules which really don't need any labeling. If they were $10 apiece I'd consider it for the convenience factor.
