Hi, I did use a single pin (thin brass rod) to keep the two halves together, but to truly keep them together and to prevent rotation I had to print the base plate with the half circle guides. In the end the fit between them was tight enough that I didn't even need the pin. When I built my next switch header I downsized the guides, they worked just as well. You can see below. cheers John

Thank you all :thumbup: Hi Arjan, yes it's painted, I raise the features by 0.4mm then paint the tops.

I sent a push button to a member in Europe, $23 postage for a $4 switch... Mouser has the rotary selector it's just the push button. If I can find one on Mouser that is close I can redesign to suit.

This is near perfection, your milling method is the perfect solution, you get the 3rd dimension you dont get from panel laser cutting. Very impressive work!

Hi Michel, You could use the callbacks to capture a state change then set the LED manually. something like this? int g_apuLEDState = 0; int g_ledstatechanged = false; void onApuReadyLtChange(unsigned int newValue) { [indent] g_apuLEDState = newValue; g_ledstatechanged = true; [/indent] } DcsBios::IntegerBuffer apuReadyLtBuffer(0x54b2, 0x8000, 15, onApuReadyLtChange); void loop() { [indent]if (g_ledstatechanged) [/indent] [indent] { //Call routine to drive shift-reg or LED controller, pass in LED state. g_ledstatechanged = false; } [/indent] }

Hi All, latest completed module, the switch cover is 3D printed as well. cheers John

I did previously do a diagram of my slave board. That had the component values in there.

Hi, I'd say CPA, EPA's look like they'd be much more expensive.

Thats looks great Alex, are they 3D printed?

I'll try that primer, thanks for the link! I've reprinted in red abs, I'm going to see what vapour smoothing can do.

Anytime, happy to help. :thumbup::thumbup:

That's the one mate, it's not obvious that that's what it does.

Thanks Casper :) It's a final push to get the last of the modules completed. This one will have all LEDS including the push buttons.

Hi Andrew, Yes I bought all the parts from Altronics. I upped the Mouser link for international users. Glad the model printed okay! cheers John

Thanks for the link, I've been looking for place to make my slave module. :thumbup:

This is a great start! Your caution panel looks very tidy. I assume you had the PCB made? Subscribed.

Anytime mate :thumbup: Your printer's got good layer uniformity, you've got a good printer! cheers John

Left Caution Panel model complete, just need to print it. Upgraded design.

Hi All, It's been a while since my last update. I've 90% completed this module. Just printing the switch guard at the moment. Here's the CAD model. Everything works with this module including the spin LED. I'll upload the completed module shortly. cheers John

Thankyou DeadMeat! I'll try this tonight.

No worries :)

To make it easier for you, I've uploaded the f3d file to my original post. You can modify as necessary. cheers John

Hi, with these I just slightly undersize a hole and press fit into the plastic. Is that okay?

Hi, you can find it here. https://forums.eagle.ru/showthread.php?t=239718 cheers John

This maybe a grounding issue where your input pins are floating. You grabbing hold of the switch grounds it temporarily. Can you confirm your centre pin ground is connected to the Arduino's ground? cheers John
