Re: CPU voltage control

Will it be possible to set the CPU voltage by software? If yes, within what limits? What is the default?

I think your friend would be better off buying a netbook and connecting it to a car battery.

Re: on board (the rpi) software tools.

I think ARM assembly is pretty nasty. I am used to Z80 and X86 asm, which is pretty easy to follow. Almost like Basic. ARM, on the other hand, is painful to do by hand.

Re: Updating the website

But if you ordered 10K kits, and if you expect a good demand, why didn\'t you do them all at once? Isn\'t it cheaper to do a big batch at once?
If you only have 100 boards printed, then it will take forever for most people to get their stuff..

Re: Rollling an OS

I think it is better to just have a big distro ported (Debian, Fedora, etc.) or else development would suck if we had to install all the libraries the tar.gz/make way.

Re: How would you use a Raspberry Pi device?

I would not risk using a 6V battery without any converter to get a clean 5V output. Maybe the board will work fine at 6V, and if it breaks it's not that expensive. But are you willing to risk your TV/Monitor and other USB devices?

Re: Will you get the A or B? Why?

I think the B model is a must for anyone who wants to use it as mini computer or server. The A model is useful if you want to play with the GPIO for sensors, robotics, etc.

Re: How would you use a Raspberry Pi device?

The lead acid batteries prefer to not be discharged at all between charges. 20% is the maximum you should discharge it, or else it will suffer damage. If you want to use a car adapter, make sure it is switching, or else you are wasting more than twice the power in heat.

Re: How would you use a Raspberry Pi device?

How are you going to connect it to your lead acid battery? I hope a switching power supply, right?
And you do realize that if you drain the battery too much, it's as good as gone, so make sure to monitor it every once in a while and not let it drop under ~11V.

Re: hotplug portable power using a USB battery pack??

Some battery chargers have a mini USB for charging itself, and an USB female for charging stuff you plug in it.
So it would PROBABLY look like this: AC/DC adapter -> USB charger -> hub -> Raspi

Re: How would you use a Raspberry Pi device?

DOS should work just fine, with DosBOX. However, the games will be pretty slow, you will get probably the equivalent of a 386SX @10MHZ or so. At least this is what I get on my N900 phone @850 MHZ.
