Yeah, I even paid a couple hundred dollars for a wireless MPG pendant but just could not get it to work, even with the component that exists for it.

I just didn't want to go spending any more cash so just made use of what I already had on the shelf. I might do down the track.

Looks awesome so far.
Adding a MPG is not that expensive.

get the 4 wire one and it will wire direct into the 7i76e MPG inputs.

For a really scary wireless solution look at the ESP32 which supports wifi and Bluetooth. You can get ones with the screen already built in.
I'm slowly working on an application using one which I've got it reading Bluetooth and rs232 devices and sending data to a TCP port and a MQTT servervia wifi. I have a couple of Bluetooth chips designed to connect to a UART but had to get a UART level shifter. They may work for you.. Now I've got the level shifter, I am too lazy to get back to it!  Hacking a commercial Bluetooth device wore me out!

A Pyhon interface that listened on a specific port for specific GUI commands would be a very cool remote control enabler for qtplasmac!

Woohoo, all the buttons worked, including the MDI_COMMAND ones.
My biggest fear now is if the EMI from the plasma affects the touch screen. That will give me one massive pet lip if that happens.

Thanks for the link, yeah they are pretty cheap.

Not too worried about the MPGs at the moment though Rod, I need to see if my table can actually make me a dollar after all the time I've spent on it. For now I'll be over the moon with a pendant with heaps of control at my fingertips. No more being at the PC with reading glasses and trying to watch the cut for tip-ups at the same time. Damn it will be heaven.

I've got a couple of ESP32 boards in front of me. I got them for something called NMEA2000 which is a communication network on boats (another project on the shelf to one day be completed). I'll see if I can find some ready made code. All I need is for them to transmit the aforementioned "command bytes".

I'm afraid you lost me with some of the stuff you said LOL. TCP and MQTT server via Wifi. Right over the top of my head.

Great work...

At least being wired you should be able to provide some reasonable grounded shielding.

Good point Phill.

If I get any issues I'll try swapping over to an aluminium enclosure (plastic right now), using a shielded cable, and attaching the shield to the enclosure. I'd probably have the "star point" of the shielding at the main control panel, so I'm wondering if I'd introduce a ground loop just by my body touching the aluminium pendant. Hmmm, might even just try lining my plastic enclosure with foil to prevent that.
The main issue is the full area of the touch screen is exposed to any EMI so I'm pretty much relying on luck there. Time will tell.
