Your Raspberry Pi Projects

EDIT: Forgot to add details

I got a PLEX server working on a Pi2. Used it headless on a holiday with a portable USB power supply and a wifi dongle.

Ingredients:
1 x RPi 2
1 x Wi-Pi (yes, that's not a typo!)
1 x adafruit case
1 x ROMOSS 10000 mAh power bank
1 x 128 Verbatim SSD
1 x Debian jessie with plex server and network goodies installed.

When I switch it on, the Pi creates a wi-fi access point that I connect to from my tablet/phone/pc/laptop etc. I then browse to the Pi's fixed IP on that wifi with 192.168.0.100:32400/web.

Voila, streaming in the car, on the beach, at the resort etc without any fuss. I took 50 movies and about 7 seasons of different series.

Very impressive.

I wonder if a Pi 1 would be powerful enough

It would manage it, just.

I doubt it would be a very nice experience.

I ran XBMC on my Pi1 for a while and it was awful.

I think there is a distinction to be made between a headless streaming server and a GUI heavy media player front end. XBMC on Pi certainly wasn't a pleasant experience (OpenELEC/Kodi on Pi2 is great!), but it's ability to serve up streaming media is largely going to rely on the amount of transcoding it is required to do. If the tablet is taking care of all the processing then all the Pi has to do as a server is get the data there.

I also did an xbmc install a few years ago and it was pretty horrible but recently with Jessie, the Kodi that's in the Jessie repos and an overclock to 900MHz it's actually pretty good. A great way to use it is to install Yatse or Kore and then you can browse your library lag free from a tablet or cellphone. That's also how you cast YouTube to Kodi. I'm very happy with it.

Where did you get the wi-pi from and how much did it cost?

That's very cool, and probably cheaper than a plex pass lifetime sub, but wouldn't it have been easier to just plug the drive into whatever device and click on the thing you want to watch?

Yes, but this way multiple devices can stream any video at the same time. Although I'm not sure if the pi2 is powerful enough to transcode multiple videos simultaneously.

Callisto, by Debian Jessie I assume you mean Raspbian Jessie? And how is the performance if multiple devices are streaming from it?
 
So, after using the Pi for all sorts of things, I finally deployed it at work to keep guard at my office door. First up, I bought a toy traffic light:

4004943011976-3-full.jpg

The kid is in there to represent the scale :D It has four sides, two each of Red Yellow Green and 2 each of Walk / Don't Walk

Then, I stripped its crappy board out (damn thing was just a random on / off thing for kids to play with)

Then, I hooked up 6 LEDs to the GPIO and into the appropriate lenses of R/Y/G on the robot.

I installed wiringPi to gain control of those pins and then installed a tiny LAMP server that allows my to connect to the pi via the LAN and set the state of the robot.



NOW: The LEDs are all fine and well but I was thinking of going bigger and better - replacing the toy with a bigger, bright version of itself, where the lenses are powered from their own source (and not the 3.3V from the GPIO). My thinking then is to replace the LEDs with relays to switch the lights on and off.

Anyone done something like this here? Anyone able to recommender what relays to use?

The Pi doesn't have the current sourcing capacity to drive a relay, you're better off using a MOSFET. Lmk if you would like a circuit diagram (and tell me the website of your local electronics store).

I use http://za.rs-online.com/web/


I have seen some projects (Admittedly through quick googles and not reading the entire thing) where relays are used.

On the plus side, I have found a source for the full size traffic light.

You have got to post a pic of that (preferably next to your door)

Pic 1 - the robot on in cube outside my office.

Pic 2 is a view of the entire robot, slightly rotated to see the size. Everyone else is in a cube farm behind the robot.

The WWW interface - it only allows my IP to change it.
