Raspberry Pi Based Studio Clock?

Me too, ideal use for the Pi

Should be very simple – heck, just load a web page up with an online clock, hit full screen and you’re most of the way there…

You can also get fancier – for a proper dot matrix display you can do lots with serially driven LED boards. http://wiki.insanityradio.com/wiki/Studio_matrix_display I hacked together in my student radio days on Arduino – Pi equivalent should be straightforward. If you have the displays, though, and want something more flexible than a web page based clock, PyGTK is a good place to start from.

And of course you can use GPS to get accurate time (bonus: the Pi can act as a network time server at stratum 1). See http://www.talkunafraid.co.uk/2012/12/the-ntpi-accurate-time-with-a-raspberry-pi-and-venus638flpx/ for a writeup I did on that topic.

Found a few others:
tty-clock
vtclock

Very basic digital clocks. tty-clock allows you to centre it so I will have a go at the over-scan to make it bigger on the TV

If you follow the guide below and replace “startx” with “tty-clock -t -c -s” it will boot straight on to tty-clock (”-t” for am/pm format, “-c” for centred and “-s” for seconds)

I recently ordered one to see what it could do. Does anyone know of any useful programs for radio related tasks? I was wondering if it could be used as a poor mans Barix Instreamer

Take a look a OpenOB made by our very own James Harrison.

Thanks Peter. I recall seeing James’s post on that, but at the time it sailed right over my head and didn’t mean a thing to me!

I’ll don my new Raspberry Anorak I’ll take a fresh look.

Peter, did you get very far on finding some suitable software?

Logically you could go beyond just a clock and add Mic Live indicators and such like as well.

I think I may have a go at programming myself. GPIOs should make it easy to do a Mic Live/Phone/studio indicator… I’ll let you know if I get anywhere…

http://shop.ciseco.co.uk/kit-relay-board-simple-to-use-3v-operation-supports-logic-level-also/ may be helpful to you Peter – you can’t switch large voltages without a relay. That will let you flip mains level voltages with the 3v3 off a RPi GPIO, and it’s go an optoisolator so you’re electrically isolated from the mains. Obviously as with any system involving mains or even 12 volt power, take care and make sure you’re safe with your wiring and cable management etc!

There are some excellent libraries for the Raspberry Pi GPIO ports in Python which may be of interest.
