Hi guys,

I am new to bitcoin mining and raspberry pi as well, however I decided to build a bitcoin lottery setup. no risk no fun.
I've got a raspberry pi, older model, a powered USB hub (Logitech), and a gekkoscience 2pac.

Today I spend a few ours to install raspbian onto the pi, as well as cgminer.

It is still not ready, however I followed the descrption on the fisrt page of this topic.
My questions would be:
Can I mine to an online wallet? if not how can I create a local one to the pi?
When I need to add username/pass - what sort of username and pass should I add? (I mean in this line: cgminer -o http://localhost:8332 -u username -p password --btc-address).
Is it normal when I plug the Gekkoscience stick into the Pi it gets really warm. Without even mining?
Sorry for the noob question, I am challenging myself with this project..

Thanks.

It should come up as one large miner, the hash amount should double with 2 pacs or triple with 3.

Assuming your using cgminer https://bitcointalk.org/index.php?topic=1764803.1240

btw: just hot plug the next one in

If you add a different type of ASIC you will probably have to recompile cgminer with another --enable-...
So it is best to keep both the compile and execution commands in executable scripts
