If you are in the US, I have a couple of extra Panel/PCB sets.

Totally gorgeous module.

I’m in Australia right now, how much could it cost though?

Oof, probably more than a jlc order.

Micro sd looks the same as a floppy almost… A natural transition it would seem.

Just ordered, cost about $US25 for the boards and $US17 for shipping to AU!

I added the “JLCJLC…” to the back of the main board

Thanks to an update to fix a shorting issue in the trigger input jacks, I noticed an issue in my back pcb. I avoided the shorting issue by neglecting to connect the tip normal in the trigger input jacks to +12v. I have updated the files on GitHub to add this connection through a 10k resistor. This fixes the shorting issue in Kassutronics design, and adds the missing connection in my pcb layout.

I have an older version of the PCB, wondering if I can just patch it like this:

Yes, resistor to 12v on the tip normal of the jacks. That looks correct.

I notice version 1.2 of the Kassutronics design doesn’t have this issue; 2.2k resistors were added between +12 V and the input jack normal pins.

Another question that might be obvious, what orientation do the D6R switches go in, or does it not matter, I tried to look at a data sheet but I couldn’t figure it out.

Maybe something can be figured out from this diagram?

It does matter for the led version. The flat edge is the negative, just like a typical led.

Thanks! it looks like the “bottom” two pints on the board are ground, if you are looking at it with the labeling the right way around:

Edit:  
But the flat side is can only be on the left or the right, still a bit lost as to which way it should go

The button has two LEDs, one each way.  
So any way you put it in, one of them will light up.  
If they have differents colors…

Oh, that little dot usually marks pin 1, which is, according to the datasheet… one of them !  
What an incomplete datasheet…

I think the dot is the positive side. I will check when I get home.

There is a green dot on one of the legs on the flat side

And indeed it is negative on the flat side, (positive on the non-flat side)

 ![IMG_6663](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/1/6/16618da3c5705354793bb470d67b39bc95500a39.jpeg)  
Is the dot on the PCB the positive side?

I confirmed the flat side goes away from the dot. Dot is +.
