Re: Low cost monitor

does anybody else feel strange when paying more for peripherals than for the computer itself? Not that this should be understood as a suggestion to raise the price of the pi just for my comfort levels, but shopping for cables, input devices etc is just just a lot less fun if your only thought is: "...

Re: Win95 on real Raspi

With 12 minutes boot time, you are significantly faster than the other person (who reported several hours of boot time :P ) Do you think you can emulate raspberry pi inside windows xp inside qemu on a raspberry pi?

Re: Overclocking

OK, I am old. Get over it. Way back in the olden days I recall that you needed the CPU speed to be a multiple of the RAM speed, or some very strange things could happen, and you got the most performance boost this way. From reading this thread it seems that theses two speeds are not connected in an...

Re: Will you ever buy another brand of embedded board?

I have in my possession a raspberry pi and a fake Arduino mega. I must say that AVR and arduino offer a wonderful demo platform both for beginners and more advanced users. I often hear that atmegas are "low on computational power", but this is really nonsense. The atmega series of chips has over 16 ...

Re: XFX 8600GT Capacitors Popped

The temperature surely diminishes the lifetime of such a capacitor, but I also believe they're just really bad quality caps On my own old 7600, the 1000uF caps exploded a while back. They're the same type as yours (6.3v). I believe it's just a bad choice to use 6.3v caps in a 5v scenario. It's a rea...

Re: Raspberry Pi Heatsink mod :)

This is cool as a customization project. It might even increase your SoCs lifetime by a couple of hundreds hours. As for practicality, it probably does lower the temperature from 40-50 degrees centigrade to around 25-30 I'm guessing. I did not physically measure this, it's a guess. My own raspberry ...

No, you cannot buy a bag of components necessary to solder your own raspberry pi. The CPU and RAM are both BGA (ball grid array, small round soldering spots in a grid), which can only be soldered by robots and a solder reflow oven http://i175.photobucket.com/albums/w143/JamesHughes_photos/RaspberryP...
