Most of these kids doesn’t reach or proceed secondary education. Because for them, primary education will suffice to live for farming and do labor works. With this new skills that they have learned, I hope that their future would change for the better.
64gig upgrade for Raspberry Pi with bitcoin-core
The whole blockchain should fit on 16gig usb drive with wheezy… but logs, source and temporary files should be considered during the process. ugh!
To be continued…
Doing 650+Mh/s
A short step-by-step on how to compile Bitcoind on Raspberry Pi.
First thing you need to do is to increase the RPi’s Swap Size
$ sudo vim /etc/dphys-swapfile
Modify the line to change the setting from 100Mb to 500Mb.
CONF_SWAPSIZE=100
to
CONF_SWAPSIZE=500
Apply the changes
$ sudo dphys-swapfile setup
$ sudo dphys-swapfile swapoff
$ sudo dphys-swapfile swapon
Check the new swap size using free command
$ free
Update your Raspberry Pi’s packages
$ sudo apt-get update
$ sudo apt-get upgrade
Install all dependencies needed to compile the bitcoind
$ sudo apt-get install checkinstall subversion git git-core build-essential
$ sudo apt-get install libtool autotools-dev autoconf
$ sudo apt-get install libssl-dev libdb++-dev libminiupnpc-dev
$ sudo apt-get install libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libboost-all-dev
After successfully installing the packages, go to your preferred directory for downloading the bitcoind source code to compile.
$ cd ~
$ mkdir source
$ cd source
$ git clone git://github.com/bitcoin/bitcoin.git
$ cd ~/source/bitcoin/src
Prepare the bitcoin source code from github
$ ./autogen.sh
$ ./configure --without-gui
Now… grab something to eat or to watch while compiling. It’s gonna take a long while to compile.
After a few (maybe hours)… you may now configure your bitcoin.conf and run
$ ~/source/bitcoin/src/bitcoind -daemon
Watch out for my next post on setting-up bitcoind (bitcoin.conf settings)
Update:
For minimal configuration… create this file in ~/.bitcoin/bitcoin.conf
server=1
rpcuser={insert your preferred username}
rpcpassword={insert your preferred long hash password for security}
rpctimeout=30
rpcport=8332
gen=0
allowreceivebyip=1

Compiling while sipping coffee… ^_^
You can make your own Wireless Access Point with Raspberry Pi using Tenda Wireless USB Adapter (W311U+). It won’t give you the same performance like the commercial one… but it will allow you to connect at least 5 devices and install network security packages to play with 🙂 neat!
Bought from Octagon Megamall with PhP600 price tag. You can also try other Wireless USB adapters like CDR-King’s… but check if it can operate on “Software AP” mode.

From average 590+Mh/s …. now can reach 700+Mh/s max. Though not a significant improvement… it’s something ^_^
Worth PhP 1, 200 with 1000 mah output, 4 port USB 3 hub… works great with Raspberry Pi and ASICMiner USB Block Erupters
Recompiling cgminer-3.7 to use both miners… encountered some errors after plugging in the 2nd block in cgminer-3.1
Hope this one works
