talkiepi is a headless capable Mumble client written in Go, written for walkie talkie style use on the Pi using GPIO pins for push to talk and LED status. It is a fork of barnard, which was a great jump off point for me to learn golang and have something that worked relatively quickly.

In the stl directory are the stl files for the enclosure I have designed specifically for the Raspberry Pi B+ board layout (I am using a Raspberry Pi 3 Model B) and the PCB and components from the US Robotics USB Speakerphone. I will be posting a blog post shortly with a full component list and build guide. For more information regarding building a full talkiepi device, go check out my blog at projectable.me.

I have put together an install guide here.

You can edit your pin assignments in talkiepi.go

const (
	OnlineLEDPin       uint = 18
	ParticipantsLEDPin uint = 23
	TransmitLEDPin     uint = 24
	ButtonPin          uint = 25
)

Here is a basic schematic of how I am currently controlling the LEDs and pushbutton:
