Re: PiBow case for b+ in USA

I just bought a Pibow Coupe case for my B+ from Pimoroni on eBay UK (current item number 141367065000). Postage to the USA is quoted as £4. Seems pretty reasonable, although the case may take a week or two to reach you.

Re: GET$ not waiting

Are you sure your program isn't messing with the keyboard auto repeat rates? *FX11 and *FX12 are the usual commands I think. The rate is often altered in a program using keys for continuous actions - perhaps in a game - or to cut out the initial pause before a key is repeated.

There's a cut in the track just above where the red wire is soldered. The switch bridges this gap and makes or breaks the circuit.

Electrically, a single-pole, double-throw switch (3 pins) will suffice, but mechanically you need the other three pins of a double pole switch to anchor it securely. That's if you're going to s...

I know that the GPIO pins cannot bear voltage greater than 3.3volts, but I have this sensor that has operating voltage range from 4.5v to 5.5v.

Re: Should I return my Pi? GPIO pins sit crooked.

Well, I wouldn't want to keep it either. Once you get that board in a case, you'll find it's hard enough trying to wiggle a plug or leads onto the pins when they're truly vertical. But if the pins are misaligned, you might not even be able to get a 26-pin IDC plug to fit through the case aperture an...

However, their major disadvantage is that they are uni-directional and the Pi's GPIOs often require a bi-direct...

Good question. What's the technical difference again?
They generally seem to refer to themselves as 'emulators', so I guess that's what they are. I presume the same goes for the Risc OS 'emulators' too.
