Re: Another single-switch circuit board

Wow.. lots of cool projects and ideas, everyone. I didn't know the SK6812MINI-E existed. That seems like the better part to use, as it should be easier to solder and the solder points should hold up longer. I'm ordering some new prototypes and LEDs to see how well they can be incorporated into the 2...

Re: Another single-switch circuit board

I've shared the project on OSH Park here , and posted the gerber files here . :) I'll clean up the sources and post those soon as well. Regarding OSH Park's milling issue, I looked at what would need to be done to mitigate and it is a significant enough change that it would warrant a version 2.1, if...

Re: Another single-switch circuit board

It may be possible to dogbone the corners. Will give it an attempt. (PCB space is at a premium.) I don't have experience with other manufacturers, but hopefully someone can offer insights. I can also produce panelized gerbers if someone can offer guidelines (optimal panel size, ability to do V scori...

Re: Another single-switch circuit board

Ah, that makes sense. Thank you for that context. I'll put together the files for release, try to call attention to the milling issue, and create the 2u version at a later date (as time permits). For now, here are a few pictures of prototypes that have been made. The first pictures show the current ...

Re: Another single-switch circuit board

Thank you! I plan to release the gerbers and sources. However, there are a few issues that need to be worked out: To make use of the Kaihl switch sockets, one really needs to use the screw mounts on the left and right sides to stabilize the PCB when a switch is inserted or removed. I don't think I'v...

Re: Another single-switch circuit board

Below is a pinout for the 2.0 design. I've ordered some prototypes to see if any other changes need to be made. Also may take a shot at creating a panel to have more control over where the mousebites end up.

Re: Another single-switch circuit board

I've made some updates that hopefully improve the design. In this revision, redundant column pads were added to the top and bottom. (Thanks, Lolligagger!) Also, pins were added to support both left-to-right and right-to-left LED data flows across a row. This will allow for the LED to always be mount...

Re: Another single-switch circuit board

I designed a revised amoeba a while back with support for SMD RGB LEDs like that and Kaihl switch sockets. Had a few prototypes made. I think where it left off was it would technically work for a single key switch, but I wasn't sure it would be feasible to wire up a matrix of them due to the need fo...

The kit includes all the stems for a full TKL keyboard but unfortunately it seems that they are not including the stabilizer housings, so a little of DIY work would be needed.

Hi mohitgarg,

There's an SVG OSH logo here that might be helpful. I had a few PCBs made to test it and it came out pretty nice (some pics here).
