8088 Corruption!

Sweet, a casing featuring the colours of the Dutch flag

It says "509 Bandwidth Limit Exceeded" at the point of writing this

Any mirrors on this?

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...

Do people fit heatsinks to their mobile phones too? ;) Yes, cellphones typically use their casing as RF/EMC shielding and heat dissipation :D Some phone manufacturers have learned the hard way that bad heat dissipation, non-reflective screens, sunlight and lithium batteries don't mix very well. In ...

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. A board I got from Element 14 last month with a "1222" production date has non-zero units. Date codes always represent PCB manufacturing, not product manufacturin...

@Lob0426 Finally there is a person which is realistic about possible changes and the lack of motivation to do so. To anyone in this thread: Why do you seek a "better/faster/bigger" raspberry pi? There are so many other demo boards out there that meet your exact specifications within the 50-150$ rang...

I'm just trying to see why would anyone consider the Pi over these other boards, at all!! :) Pi is cheaper, GPIO access with fancy PWM, better support through professional companies like Element14 and a vast community, has a camera connector, has screen connector (DSI, composite), multiple supporte...

Perl, sed, awk, bc, dc, find, grep would be fine I think to most pearli. Perl is quite modern with a reputation for not being relevant for anything but string transformation and parsing problems. There is no reason why some of the problems can not be solved on a Pi. Even the C language would not be...

I note you did not quote my bit about 13A (thirteen Amp) sockets wired with 3A (three Amp) cable very teling. Live in the real world a general computer with USB ports will have users plugging in any USB device that was the point of the standard. The micro USB connector for power was a silly idea fr...

reiuyi

Yes no maybe, in general yes, but limiting the power for USB BELOW the spec, means there will be problems when even more users or teachers or children go its a USB socket I can add my USB wifi/cam or other gadget, but it wont work. Waiting for a 2.5in USB hard drive to be added. If you put a standa...

You should have a look at http://www.raspberrypi.org/phpBB3/viewt ... 62&t=10635

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

It felt a bit silly to see a Python forum but not a Perl forum. Those languages are like brother and sister. In many institutions, Perl is still a nice introductory languages into programming, because it's so easy and the commands are quite literal. It was the first language I got to learn :D. I hat...

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. USB power: Works fine for its intended goal: keyboard and a mouse. Even usb sticks work! Sound: It's ab...

It does make me wonder what the camera and display will be nicknamed as

"Cloudberry" sounds like a typical name I'd come across in my travels in The Elder Scrolls games

The UK has wall sockets with switches, right? http://img.diytrade.com/cdimg/1504691/22437799/0/1315548089/Electric_Wall_Switch_Socket_Power_Socket.jpg And for those that don't, I've seen this in general goods stores for like a euro each: http://ecx.images-amazon.com/images/I/41J2OFZiMUL._SL500_AA300...

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...

And yes those people who are great and are judged as Outstanding or are working in more difficult roles (e.g. in inner cities with more challenging catchments) should get paid more. Its the same in industry and based on merit. Currently it doesn't matter how hard you work as a teacher until you hit...

I always thought Elektor kits were very expensive, and some of their "kits" use PIC-microcontrollers with all the security fuses blown so you can't ever see what's going on inside the thing (why on earth would anyone do this on an educational kit??). Apart from that, they're probably fun kits for ev...

I'm looking the cat out of the tree

That hits side nor shore

You harvest what you sow

The clock doesn't tick the same anywhere like it does at home

Butter with the fish

As for myself, I think that any deviation from standard x86 platforms is an enrichment. Can you explain this statement in your own words, please? Almost the entire non-mobile computer industry is based on x86 and x86-64. Aside from the 64-bit address spaces, x86 has also remained a stable platform ...

This thread has deviated far from its original subject! :D Farnell now says if I order today I can expect my PI in three weeks. If I order any part from farnell, it is usually delivered the next day! So I guess there is still a backlog of sorts. There must still be a backlog, I can't imagine them h...

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...

Hey. what are the chances the foundation could get on this? If they don't want to sell stickers, could we make our own and distribute them? Not that we want to steal the logo or steal your intellectual property (I think that concept is BS but I generally try to respect it), but if you aren't going ...

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 ...
