A little break (strangely coincidentally, just as my penultimate term ended and my final year project got finished and handed in) later, and here we are again – another post in my series on engineering FM transmission at a community radio station.
This time I’m going to be talking about how to properly power a transmission system, and how best to deal with uninterruptable power supplies (UPSes) in terms of cabling, monitoring and long-term care. Continue reading Engineering FM – Part 5
I know, I know, long time without a post! I’ve been busy. Normal service will be resumed here shortly!
So the other day I wanted to hook up an old projector I’d gotten my hands on a while back to my MythTV box in a dual-screen (TwinView) configuration. So I duly plugged it in. Nothing happened. Updated the drivers (Ubuntu 10.10) through the hardware drivers panel, and while my normal monitor was fine, the projector wouldn’t allow a resolution greater than 640×480. Annoying.
Fortunately, I could trace this down to the EDID data from the projector being dodgy (or something along the way causing problems- the cable is a dodgy thing from China, so that’s a potential culprit). Basically, nVidia’s drivers don’t let you ignore EDID data, even with the NoEDID option in xorg.conf.

Or- how to make TV worthwhile if you happen to have a leftover Sky dish on your house.
So when I moved in to my current university digs, the previous tenants had left a few things behind. Notably, they’d had Sky. So we had a Sky box in the living room and a dish on the wall. In the UK, if you want fast internet these days, you need Virgin Media. VM gives you cable TV in the bundle, so I didn’t want to pay for Sky. But Freesat’s got some nice stuff on it, including BBC HD and that sort of thing. So how about we get ourselves some free TV? Continue reading MythTV and Freesat
