I’m running tech and DT for the Manchester Cadet next weekend.
One of the things we were asked to look in to this year was streaming the event. There’s a number of ways to do this, ranging from hiring camera crews and per piste cameras through to cheap webcams showing the entire venue.
I also needed some kind of box to capture the feed and push it somewhere useful, say Youtube Live.
There’s a off the shelf devices that can do this, but they tend to start and more than pennies and go to OMG-lots. This is a first year test, we simply want to see how it works. So I ordered a Pi, a case and a Pi Camera.
I’ve not really used a Pi previously. I’ve not had a need. I have a big machine that I use to do programming on, and if I want to do embedded-type things I tend to lean towards Arduino. But I needed more than an Arduino and less than a full PC, so I Pi it is.
And I think I sort of get it now.
There’s a few distinct advantages to the Pi platform:
- Cost. It’s practically disposable. Board, camera, and case cost me ~ 50 GBP. If something happens to it, I’ll be annoyed, but not … painfully upset. Because I need two, I can just order another set of components for not much cash.
- Modularity. I have two Micro-SD cards. The first one, an 8GB is running Raspbian, with a few scripts on to start the camera and stream to Youtube live. It’s configured to run on the network that’s sat next to me on boot, which I can then access via ssh. The second one, a 16GB SD card, is rigged for fun, and is running RetroPie with a whole load of ROMS. We killed a couple of hours last night having fun playing old SNES games with a 360 controller. Switching between these two very distinct functions simply involves removing the camera, and changing the MicroSD card. Superb.
- Cloneability. I need a second camera. I just buy a second set of components, clone the MicroSD (which should take a whole five minutes) and I have a complete, second unit. Oh, and quickly change the second static IP address.
- Dispos…ability? I screwed up the first attempt at getting the camera working. All I did was clone a new SD card, and we were going again.
There’s other advantages with HATs, shields, GPIO, electronics. Cool. But as a basic “throw it together” platform to solve problems[tm], it’s superb. And a lot of fun.
When this event is over, one is going to be used more pernamently for emulation, the other may become a holiday cat-camera or some such. More ideas to come.
