I have a spare raspberry pi anything interesting or cool i could do with it

use it as a PC  ;D ;D ;D

home automation, like opening door and lightning of yor using with your handphone via internet connected to the raspberry and the raspberry set it on using either relay or you can rig an remote controlled plug.

go to pirate bay and find lots of books about fun stuff to do with a raspberry pi

Make a cold storage wallet out of it :D

You could build a camera with it, a Miner, A PC or something techy.

i saw that you can run a hyperstake wallet on raspi

Thats what I was thinking of doing my friend,will let you know how I get on

I would honestly do this.

I've been wanting to wire up my apartment for a while.

But, you should do this: http://jasperproject.github.io/

hmmm

fully automate, internet and voice controllable  ;D

I don't know about how to do anything cool with the Pi, but I just use mine as a safe computer to store and use my bitcoins and just boot it up whenever I need to spend them.

are you shipping worldwide or your country only
you should post a sell thread in computer hardware section
you can find many buyers there

Haven't seen a Pi for sale for a while on here, but if you listed it I'm sure someone will buy it.

I tried running a full node, but it's too low on memory.

have you try using swap memory ? maybe on harddisk ?

Yeah the whole thing grinds to a crawl. Even compiling the source code overflows into swap space.

hmmm... did you use swap file on the flashdisk ?

 i once try compiling with swap file on harddisk and removing the swap file from flashdisk.

I only had a SD card mounted.
I run a full node on another machine now which is more suitable.

You can use it to create an emulator box that you attach to your television.

It's pretty cool.

Use your Raspi like a VPN for your mobile phone

Came here to say the same. You could do an NES emulator, complete with tiny case.

If you don't have a 3d printer TECSHARE is offering to print up things around here somewhere.


This guy is selling B+ models shipped from China.

well the swap on sdcard is too small and the speed is not adequate. if i remember correctly i use swap partition on harddisk and swap size is around 2G, it can compile ok that way.

 i recommend try create swap file on external harddisk and mount it :


#Creating swap file#

dd if=/dev/zero of=/SWAPFILE bs=1024 count=524288
#This will create a 512MB blank file.
#Change the count= to your preferred size.
chown root:root /SWAPFILE
chmod 0600 /SWAPFILE
mkswap /SWAPFILE
swapon /SWAPFILE


or

#Setting swap partition#

dd if=/dev/zero of=/dev/sdXN bs=1024
#This will fill the entire partition of /dev/sdXN
mkswap /dev/sdXN
swapon /dev/sdXN
