Re: Gertboard AVR without Arduino IDE (howto)

I hope this is useful for someone.
Yes, it is.
I had been looking for the steps to do the tradional way to programming the AVR - and now it is available.
Your description is very helpful,
many thanks,

Re: Will Initial GPIO State tollerate 3.3v or being grounded

seems it activates the "Safe Boot" mode, found http://www.raspberrypi.org/phpBB3/viewt ... 13#p129413
If you have the recent official raspbian image, or have updated your firmware since that was released, then the Pi supports a "safe mode".
You need to add a jumper between pins 5&6 of P1.

Re: Wich Power Supply for several RPI

- simple and safe attempt: 1A per Pi results in 36 A
- lowest power comsumption, no interfaces, no overclocking 0.5A per Pi -> 18A
- the average: 0.75 A per Pi, gives a total of 27A
what about 30A @ 5V ?

Re: Be aware of adafruit 5.25V adapter

My opinion is that the polyfuse(s) are another elephant for the Pi, especially when the Pi will arive at the not-so-technical audience. The real problem may not only be the power supply, it could just as well be the fuses. The foundation and RS/Farnell should eliminate F3 like F1 and F2. Or the supp...

yes, it is - but 1.1A will do it the same, with a lower resistance.

Hi Tom, I asked at a local electronic store with smd parts for a suitable replacement, and found a SMD polyfuse with 1.1A instead of the 0.75A type. Soldering was not a problem due to the relative big size of the component. For testing it is possible (on your on risk) to bridge the fuse - if your po...

There is another fuse under the board, labelled F3, between SD card and USB power connector. I had a Pi, where the resistance of F3 was 3 times greater than average (0.9 Ohm vs...
