Re: Southern New Jersey

I can't speak for where the new pi's are in stock, if that is what you mean, but I bought most of my previous ones at Element14.

Re: Fireworks Launcher

Well, it is getting close to that time of year again and the itch is back. I haven't turned my pis on in almost a year, so I better start checking them out and doing some software updates. I am thinking of switching from Wheezy stable to Jessie testing, as I suspect it has stabilized a bit by now. A...

How can you even compare an Android consumer device with a Raspberry Pi development board. You are talking about two completely different products for two completely different audiences.

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

there will be no more "bowing" than normal, except of course if you try to force it to become horizontal, obviously. the slight angle does not prevent a normal header connector to fit, and the 1 to 1.5 mm more height on the left side should fit into most cases. I only foresee one potential problem,...

Wow, actually amazing that this passed quality control. Yes, it might be fine electrically but I say definitely exchange it, you never know what you might want to do with it later; something which isn't possible now with the awkward geometry of the pins. +1 about the quality control. No way I would...

Rather then guessing what resistor is going to work or not, you should calculate it, or even easier use one of the very simple calculators that are available online like this one:

Re: USB Hub and back power

The main issue with backpowering/backfeeding is that it bypasses the fuse protection of the pi. The fuse is located immediately after the power is fed through the micro usb connector, and backfeeding applies power at the other end of that circuit. Therefore you are either relying on the fact that th...
