Raspberry Pi and Mining
Raspberry Pi
If you haven't heard about it already, the Raspberry Pi is a $35 computer powered via micro USB and runs linux. Or, a fancier description from the company:
The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It's a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
I ordered my Raspberry Pi a few months ago and I just got it a few days ago. It's been pretty fun to mess with so far.
- One thing I've done with it is install RaspBMC . It's a linux distro that boots directly in to the XBMC media player. Since the RPi can output over hdmi, this makes a great cheap home theater pc. I was able to play all of the SD content flawlessly off of my usb external hard drive. It couldn't handle my 1080p content, but that wouldn't have been an issue if it was encoded using H.264.
- I already have a htpc though so I've reflashed the SD card with Wheezy, a debian based linux distro. I'm mostly just using it for tinkering at the moment and I hope to connect it to a lapdock soon. I've ordered all the parts, now I just have to wait.
I connected my RPi to a PyMCU, a python controlled microcontroller.
BitCoin update
My last blog post was about mining bitcoins and I wanted to share some of the numbers so far!
Before I get to the numbers, I thought I'd share more information about the rig the graphics cards are mining in. (Keep in mind that I didn't buy these parts for mining, I just had them from an old computer)
Desktop
- Motherboard: Asus P6X58D
- Processor: Intel Core i7-930 Bloomfield 2.8Ghz
- RAM: Corsair Dominator 12GB (6 x 2gb)
- Graphics Cards: Sapphire AMD Radeon HD 5830 x2
- Power Supply: Corsair 850w
- Case: Antec 1200 Full ATX
- Boot Drive: 1TB 7200rpm Sata 3.0Gb/s
I plan on moving my server programs off my main computer and on to this one since it could mine while doing simple server tasks. (More on that in a future post)
I roughly followed the Complete Guide To Mine Bitcoin on Xubuntu 12.04 guide while setting up my miner.
The main difference is I used Ubuntu 12.04 Desktop LTS.
Here is my mining script:
#!/bin/sh
export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
cd ~/cgminer-2.5.0-x86_64-built
./cgminer -o http://mine2.btcguild.com:8332 -u ******* -p **** --api-listen --api-network -I 9 --gpu-reorder --auto-fan --gpu-powertune 20 --gpu-engine 830-880 --gpu-memclock 300 -w 128 -g 3
I am also running openssh-server so I can ssh in to my miner and start/stop mining and check gpu temperatures.

Bitcoins and Hard drives in statuses
I took a short break from writing for awhile. So here's an update! I've been a fan of bitcoins for awhile now. I won't explain them in depth in this post as there are much better resources elsewhere on the Internet. I started mining bitcoins almost a year ago with my AMD HD 6950 graphics card which has worked wonderfully. Sadly, I've sold bitcoins at times when I should have waited, but even with my lack of "stock" knowledge, I've earned a decent amount of dollars with them. Recently, their prices have been rising and are becoming more stable, and I've upgraded my computer since then. This left my old computer just sitting around being a (pretty bad) file server. Not anymore! Dedicated Bitcoin Miner...
Site Updates in statuses
If you haven't noticed, I've made a few changes to the site lately. I've redesigned the favicon ( ), along with a new badge/logo which replaced the old "Nolat" link in the navbar. If you look closely, you will also notice that the background and content area of the site have had subtle textures applied to them. They definitely give the website a nice "feel." Additionally, I've modified the navbar to have dropdown boxes and added a few more options to the Contact Me link. The Quick Message method is pretty cool, I made it myself. Filling out the form that appears will alert me via email (or a text message if I enable it). So what's the point of using it if it just...
Internet Lamp in statuses
Just because it doesn't have an ethernet port doesn't mean you can't control it over the Internet I have successfully controlled a lamp via the Internet. While I'm sure there are much less convoluted ways, this post will give a brief overview of how I did it. This isn't meant to be a tutorial, it's more of a high level summary. Here is a short video of it in action: Items Used: X10 Wireless Transceiver Module X10 Appliance Module* X10 Firecracker A lamp *This may not be necessary. Some X10 Wireless Transceiver Modules have an Appliance Module built-in. The one I have claims that it does but I couldn't get it work.
