Raspberry Pi - Who's gonna have a dabble?

Very good, have you got Out Run and Afterburner on there somewhere? I was trying to get a Sega Saturn emulator running on the PC the other day and it was driving me nuts. Gave up eventually.

I got OutRun going but it was a bit glitch and slow at the start, improved once past the busy bit with all the people on the grid, early days yet so quite a bit to do with conmtroller config, getting roms and getting setttings optimal so I can enjoy a game, pleased that I put it together an dit all worked ok as a lot of splicing and soldering went on.

I've just installed Musicbox on an old Model B Rev2 and it's works quite well. I like how I can stream straight from my Google Music account too. I'm after an amp for it now though so I can connect it to a couple of small speakers I have lying around (Kef Eggs) hifiberry seem to be sold out of the amp for the older Pi and IQaudio are a bit steep at £55. Does anyone know of any alternatives, Chinese copies or whatever are acceptable but I can't seem to find much.

Getting some playback issues on a Pi2 with OpenElec and some large video files hosted on a NAS.
I've just ordered a 128Gb USB stick (£22, nuts) to serve as local storage to remove any potential network bandwidth issues, but wondered if anyone had any thoughts on what might be causing it?

For reference the files are circa 5Gb episodes of Mr Robot.

What do the playback issues look like?

[weeboot]

Random short pauses.

Almost handy as a plot device to give you a moment to think, but not the best!

Could be CPU bound. Might be worth running top (which would probably make the situation worse while it's running) and seeing if the CPU is hammered.

NFS is better than SMB for this if playing over a network.

It may also be possible to push processing the audio off the Pi and onto the TV / AV receiver by adding this line to /boot/config.txt and rebooting:

hdmi_force_edid_audio=1

Overclocking's another option, but I don't think it should be necessary.

[weeboot]

I'll check the settings tonight and see what I can do.

NFS would mean reconfiguring the NAS, which I don't particularly want to do.

[Berz]

I had the same on mine when the pi was on wireless. Switching to powerline adapters fixed it for me.

Hope you enjoy the series, I found it pretty entertaining.

[weeboot]

Wired network, 100Mb connection.
NAS has Gigabit.

2 episodes in, really enjoying it.

5GB for a 45 minute episode, am I reading that right?!

About that, yes...
Not at home, so can't verify details right now, but full season is circa 39Gb!
Quality is bloomin' awesome though..

Anyone manage to get sky go working on the PI?

Seems spectacular overkill for a TV show - but maybe that's just me! anyway not sure I'd expect my Pi to deal with a file this size.

My original Pi B played the de-specialised version of Star Wars (18gb) without issue streaming from a Microserver across a wired network.

That'll never work; it's just Sky in the Pi thinking.

[plasticpig]

Anyone built a PI based robot?

Fancy having a dabble and thinking about something like this

Whilst playing Mr Robot and freezing..
Doesn't seem to be a system resource issue, so perhaps is a bandwidth issue?
Waiting for the USB stick to turn up so that I can rule that out by providing local storage.
For reference, this is overclocked to 800

[Bullett]

Is your PSU up to the job? cheap ones can cause serious performance issues.

[weeboot]

I'm starting to wonder whether that's the case...
I'll swap it out and see what happens.
