Re: Pibow and Adafruit low-profile Micro SD adapter

I needed a flat microSD adapter (same width as an SD card) so I couldn't use this. I found a guy on ebay that makes them and it works perfectly. He also makes a similar one especially for macbooks. If you search for: "microSD short adapter" on ebay you should find it (unless the seller changes thei...

Re: Can I use this as a power supply?

As many others have suggested on the forum, you may be far better off using it with a powered usb hub. This is true - but you still need to make sure the power supply (in this case the hub's power supply) is adequate to power the hub and every device that will draw power from it, including your Ras...

Re: USB Hub Powering RPi

There are two distinct questions here. 1) [..] 2) Can I (safely) power it from a hub that the Pi is also using as a regular USB signal hub? That's more complicated - and the answer seems to be: a) No in the earlier board revisions (because of polyfuses and diodes) I'd have to respectfully disagree....

Re: How long does the pi last?

The most commonly reported fault in these columns seems to be a broken SD card slot. Strictly speaking this is probably damage rather than component failure, but it renders the Pi inoperable nonetheless. I don't suppose they fail spontaneously, but if a Pi is dropped with a card in the slot, or any ...

But , if you can solder normal through-hole components into a pcb then you can also solder up a Gertboard. That's where I was: I had never soldered smd components before a...

Re: Raspberry Pi, portable power supply

A better solution would be to use a 6xAA multi-block pack to make 9v and since one Ni-MH AA is approximately 3000mAh you have a total of 18000mAh to play with. :) I don't think you do. If one cell gives you 3000mAh at 1.2v then six of them in series will give you 3000mAh at 7.2v, not 18000mAh. You ...

I use a Logitech EX110 wireless keyboard/mouse combo, plugged directly into the Pi without benefit of a hub, and it's fine. (I've also used it with a powered hub, and that worked too.)
