Re: Limiting CPU usage for all processes

You could also check out the 'nice' command if you only want a process to use spare cycles. eg. nice -n19 command will give lowest priority to command and stop it from hogging the CPU. conversely nice -n-20 command will give the highest priority to command and stop pretty much anything else from get...

Re: Cut the power cord!

2S (7.4v) RC car LiPo batteries in conjunction with a 5v UBEC would be ideal, you just need to make sure you don't drain them to below 3v per cell. With that UBEC you could go up to 6S (22.2v) which are used in planes/helicopters, but they don't come in a hard protective case, LiPo batteries are fa...

Re: Hauppage Nova-T stick DVB-T

Firmware for the tuner will normally live in /lib/firmware.

In a terminal run dmesg. It'll tell you what the name of the firmware it expects is.

Re: how to start Scratch properly on remote X session?

Re: On the fly mpeg2 to mp4 conversion from DVB-T SD Freevie

Unless the rpi gets hardware mpeg2 decoding and hardware h264 encoding there's no chance, even then it'd probably be pushing it. My desktop (dual core 2.6 GHz) doesn't have the power to do it in software.

Re: DC-DC Converter for battery power supply

I'm assuming as they're RC car batteries at 8.4V that they are 2s LiPo. A 5V BEC as used in RC helicopters and nitro cars would probably serve you well as an alternative to what's already been advised. Also using RC car LiPos I don't think you have too much to worry about the voltage dropping out of...

Re: newbie VNC question - how to close

You're welcome. No need to keep my name in there.
I'd looked it up in the vncserver man page a week or so ago when I was looking at scratch which doesn't like to run on a remote X server (using ssh -Y) when run with the default commandline.
