Re: What if the Power Input is not exactly 5v?

There is a good chance that the RP can be powered directly from 4 rechargeable NiMH cells in series.  I'd rate the chance with alkalines somewhat lower. The nominal cell voltage of NiMH is 1.2V, times four that gives you 4.8V before internal losses, discharging through use, and cable/polyfuse losse...

Re: Rassberry Pi and Jack audio

I'd like to call your attention to the fact that your program is complaining about the fact that it cannot allocate 82 megabytes of ram for itself. Do you have 82 megabytes available? I suppose it should start swapping if not, but here we have a bus error instead. Maybe its requesting wired down mem...

Re: What if the Power Input is not exactly 5v?

<t>What happens if this is true? I'm sure this on here somewhere but I couldn't find it.<br/> <br/> I've heard it can be powered from AA batteries. If this is true there must be some amount of tolerance on the voltage range of the input. Since batteries inherently develop an internal resistance once...
