Recently my company purchased a Raspberry Pi for me to experiment with.  The Raspberry Pi  is a credit card sized development board/computer which runs the Linux operating system (can run Android too.)  This product boasts a Broadcom BCM2835 system-on-a-chip (SoC), meaning that the chip is the computer.  What exactly does that mean?  Computers, desktops and laptops, if you were to open them up you would see a circuit board with several “Chips” on it.

A Computer Chip is an integrated circuit containing hundreds, thousands and even millions of transistors and diodes.  Each chip preforms a special function, like operating the monitor, operating the port that your mouse, keyboard and memory devices plug into, plus the many other functions like audio, etc.  All of these chips are connected to a larger chip called the processor or CPU which uses an operating system to do all that needs to be done, (run software and talk to the other chips.)

The Raspberry PI has 2 chips on board.  The main chip, or CPU is what is called the SoC or system on a chip which is a 700 MHz ARM processor and 512Mb RAM.  This chip has everything built into it, CPU, MPU, Video chip, Audio chip, USB chip……..  You get the point, the chip “IS” the computer.  The raspberry also sports 2 USB ports, Audio out, LAN connection, HDMI video out, SD Card slot (up to 32Gb,) PAL and NTSC video, but no VGA, power connector and 3 headers (connectors) for connecting project boards, etc.

Having the ability to run a full-fledged operating system means that this device can do anything a full sized computer can do, listen to music, watch video, word processing, connect printers, programming, on and on.  Having “Headers” means that an experimenter/geek /nerd/tech/engineer can experiment with project boards or specially designed equipment.  There are several projects on the net for the adventurous. If tech is your thing, then the Raspberry Pi is your choice.

In the future I plan on posting my initial setting up of the RPI and pitfalls that existed for me, my success with using the FTDI USB232R with a 2×16 LCD and my adventure getting the MIMO 7″ Touchscreen LCD up and running.

“No amount of government intervention can prevent irrational people from doing terrible things,” – Senator Richard Shelby, (R).  If Senator Shelby believes that no amount of government intervention can prevent violence, then why did the senator vote for intervention in the middle East?  [S J Res 23 – Military Force Authorization]  If the senator is so reluctant to have the government intervene to prevent violence, then why did Senator Shelby vote for H J Res 114 the use of military force against Iraq?

I can extend this argument to other policies as well, since the senator believes the U.S. government is so impotent then why is the senator constantly voting against a woman’s right to choice? [ http://votesmart.org/candidate/key-votes/53266/richard-shelby/2/abortion#.UXAEkcrJKjg]

“People who steal guns do not submit to background checks, – Senator Chuck Grassley, (R). Just exactly how do background checks trample on the second amendment Senator Grassley?

Who are these wolves?  They are constantly voting to restrict the rights of the individual, yet so determined to allow guns to be freely available to people who shouldn’t be allowed to have guns simply because the government is impotent?  Maybe the senate needs Viagra and stop engaging in transference.  The impotence is yours and yours alone Senators.

 

So how does my garden grow? very well thank you.  As promised, here are photos of my Patio Jungle.  The Tilapia are doing well and the plants are doing very well.

The second tank design (at the back) as it looked after transplanting the starters into the grow bins.  The tanks utilize a 160 GPH pond pump.  The aerator has a dual output so it supplies air to the fish in both tanks.  The timer is a cheepie mechanical dual outlet type.  During the day the water is pumped for 15 minutes every hour and 15 minutes every hour and a half at night.

There are all these ads for “Survival Seeds.”  If there were a catastrophe so bad that you had to rely on them, you would starve long before they were ready to harvest.
