Re: Connect Pi(A) to Pi(B)

An alternative to Arduino is mbed http://mbed.org/ . Currently mbed supports 25 different arm based microcrontroller boards and the cheapest are ST's nucleo boards at less than £8 excluding vat. They all have more GPIO pins than a RPI, plus the online compiler is free and easy to use. I have had a F...

Re: RaspBerry Pi(e) Model C (imaginations & wants)

@rpdom
I did wonder if the lan chip could be replaced or not . I'd rather see a third usb socket than pins but,the forth port could be put on a header.

Re: RaspBerry Pi(e) Model C (imaginations & wants)

Top of my list for a Rpi model C would be a third USB 2.0 port, so I could connect microcontrollers, hard drive or memory sticks ,etc without the need to buy or use a hub. This would not only save on cost, but also, not having another two cables and box sitting/ lying on your desk. Even this would r...

Re: Question about using the RPi with a relay.

The relay board is designed to run from 5v including the opto isolators, 3v3 is not enough voltage for reliable operation. There are two leds and a resistor in series (one led is inside the opto isolator.) The stated drive current is 15 t0 20mA for each channel, which I assume is the opto isolator p...

I'm typing this out on my 512mb(384/128 mem split) Rpi so all is well:) Would agree the lack of sticky tape is more to do with cost cutting and it's nice to know other Pi's have red dots:) (or Pi pox) The only thing which could cause concern is the audio socket pins if they are touching.

Re Pictures,
I will have ago at taking some but I've just put the battery on charge. I have straightened the audio pins they could to with cropping.

One other thing is on the leaflet stating it's a 512mb Rpi it states "Faster, Double RAM, Same Price"
Why faster?

Re: Minor improvements for a model C

I agree that a basic Bios on board the Rpi would be a good idea for the reasons mahjongg gave.
But I also think, to justify including an onboard Bios you would need to include boot options either from
the SD card or from a USB device.

Re: Overclocking

Thanks for this upgrade guys:)
I thought my Pi would crash as the onboard voltage is 4.74v at 700mhz.
But testing it in Turbo mode (1ghz) playing penguin puzzle, I had no issues.
I've now set it at 900mhz which I'm happy with as everything is just that little bit faster.
Thanks again
Mark.

Re: A RPI USB power question

A revision 2 board has the 5V supply directly connected to the usb ports, looking at the photo of the revision 2 RPI. So you could uprate the 750mA fuse.
Personally I would use a power usb hub, but you have stated you don't want to do that.
