First, a little overview of the entire system.The Biomonstaaar algae bioreactor is an open source, automated photobioreactor (PBR) array with future applications for genetic engineering,bioremediation, and space research. It consists of an upright cylinder column with mounted sensors for monitoring key aspects of the culture's health suchas pH, temperature and dissolved O2. The sensors are integrated with a Raspberry Pi - Arduino microcontroller system which provides a Graphical UserInterface (GUI) for users to view the sensor data and operate the bioreactor from a Web browser.When you complete this project, you will be able to access the Ras Pi from your computer or from any mobile device with a Web browser. Just connect your device to thesame WiFi network as the Pi's, then point the browser tohttp://rasman.local:3000You will be able to view simulated measurement data (the Pi collects new sensor readings every 5 minutes) and you can also activate the control buttons. Of course ifyou want actual data, you'll have to build the entire Biomonstaaar bioreactor. :-)Here are the Instructables for the other components:Arduino interface for the bioreactor sensorsHeating and Cooling SystemControl board for the Heating / Cooling SystemFlourescent Lights Skill Level:  IntermediateTo build this project, you should ideally have some familiarity with using microcontrollers (eg, Arduino, PIC, Raspberry Pi) and running command commands on aterminal console.Now let's get started!  http://www.instructables.com/id/Rasman-Raspberry-Pi-manager-for-the-Biomonstaaar-a/  Step 1: Materials Needed Required Parts to get a functional Ras Pi Raspberry Pi, Model BRaspberry Pi case (optional)mini-USB power adapter: regulated 5VDC, 1000mA output (Note 1)SD card, Class 10, 4GB or more (Note 2)Edimax USB WiFi dongle (Note 3) Suggested Parts While you can get by with the above kit, you'll need to connect the Ras Pi to a laptop/desktop computer via a serial cable to set it up. An easier way, and what I wouldrecommend, is to attach a monitor, keyboard and mouse to the Pi. To do so, get the following items:HDMI cablecomputer monitor with HDMI video inputUSB keyboardUSB mouseUSB hub with power adapter (eg, DLink) Notes 1. More than likely, you can use a USB phone charger for this. In my case, I used a Motorola charger.2. I bought a micro SD card and used an adapter.3. Any USB WiFi dongle that is compatible with the Raspberry Pi would do. Step 2: Create a bootable OS image In order for the Raspberry Pi to run, it needs an Operating System. There are several OSes available and I chose Raspbian, mainly because I’ve used Debian inthe past and like it. Now, let’s create the bootable OS image. You will need a computer with an SDcard adapter as well as a blank SD card. The instructionsbelow requires typing commands on a Unix terminal console. If you want a more user-friendly tool, head over to eLinux's RPi Easy SDcard Setup guide and pickthe one that’s works best for you. Otherwise, here are the steps: 1. Download the Raspbian Wheezy raw image and unzip. 2. Insert the blank SD card into yourcomputer's media slot. 3. Open a terminal console and run these commands: Identify the disk (not partition) of your SD card and unmount it. $ diskutil list $ diskutilunmountDisk /dev/disk2 Write the image to the card. This will take several minutes and it may look like the command is hung. Be patient and wait for thecommand to finish. NOTE: I wrote the image to raw disk (rdisk2) for faster copying. Also, use the actual name of the image file. $ sudo dd bs=1m if= 2013-07-26-wheezy-raspbian.img of=/dev/rdisk2 When done you should see something like this: 1850+0 records in 1850+0 records out 1939865600 bytes transferred in371.561630 secs (5220845 bytes/sec)  http://www.instructables.com/id/Rasman-Raspberry-Pi-manager-for-the-Biomonstaaar-a/  Step 3: Assemble and turn on the Raspberry Pi The Ras Pi is a well designed microcomputer so setting up the hardware is pretty easy.Put the Rasberry Pi inside the case (if you have one).1.Connect the Pi to the computer monitor using the HDMI cable.2.Plug the Edimax WiFi dongle into one of the Pi's USB ports.3.Plug the D-Link USB hub into the other USB port of the Pi. Then connect the keyboard and mouse to the USB hub and apply power.4.Insert the SD card with the loaded Rasbian OS.5.Finally, plug the 5V power supply into the Ras Pi's (flat) USB port and apply power.6.You should see the red LED light up on the Pi and the OS booting up on the computer monitor. Step 4: Configure the OS If needed, change keyboard layout. I changed mine to US Keyboard layout as follows.1. $ cd /etc/default$ sudo vi keyboard Change the value of XKBLAYOUT to us then close the file.2. Change your Pi's hostname. We'll call it rasman but feel free to choose another name. $ sudo vi /etc/hosts Look for the line with the entry 127.0.1.1 and hostname raspberrypi. Change raspberrypi to rasman then close the file. This is the only line you edit. $ sudo vi /etc/hostname Change the name from raspberrypi to rasman then close the file.3. Reboot the Pi so all your changes take effect. $ sudo reboot
