Re: Practical uses of diodes

I'd almost say it's ironic that with modern-day transisors, it's easier and cheaper to build a DIY FM-transmitter than an AM-transmitter, despite the fact that in theory AM should be way easier to construct! Those damn copper prices...! The device that always comes to mind is Talking Electronics' "F...

Thanks much. I'll see if the ones that are in transit (shipped Friday from Allied, due to arrive on Wednesday) have the zero ohm or not.

Re: sub-forum request - Perl

Perhaps you can contact the OP of that topic. He has done great work so far to optimize qEMU for running a 486 quite fast on the raspberry pi. He even got some games to run on it, very interesting stuff

None of the points you mentioned matter to the educative goals. You're allowed to use raspi as whatever (it's yours, you bought it), but don't expect any hardware changes for non-critical aspects.

Re: Another potential development board

A direct comparison between Raspberry Pi and the Allwinner A10 is unfair, though. You got lucky with customs, otherwise this development board would have been easily twice the retail price of raspi. As far as I can tell the onboard wifi is an amazing advantage. The size is a lot bigger than raspi. I...

Re: Yet another PSU thread...

The NCP1117 3.3v linear regulator has a quite high drop-out voltage of 1.2v. Meaning the absolute minimum input needs to be 3.3v + 1.2v before serious issues of rail-regulation start appearing. So it's not uncommon to see raspberry pi running stable at just 4.5v. I've seen mine boot even with like 4...

Well all I can say is that there's a reason many power supplies from USB hubs were made to deliver 5.2v instead of 5v stabilized (diodes dropping voltages, higher current dropping voltages). Please remember that plus/minus 5% will not affect performance. A reading of 4.7-4.8V won't affect stability ...
