+====== About! ======
+This page is a collection of mini-tutorials on doing stuff with the Chumby Hacker Board (for brevity we will refer to it as the CHB)! The CHB is a cool single board Linux computer that has much of the same hardware as the famous [[http://www.chumby.com/|Chumby One]]. It's great for people who are experienced with Linux and want to have the power of a microcomputer with audio and video output while at the same time getting all the peripherals of a microcontroller such as analog-to-digital conversion, PWM outputs, sensors, bit twiddling, and broken-out GPIOs!
+While we believe that the CHB is a fairly easy-to-use Single Board Computer (SBC) having a pre-installed OS on the included uSD card, and ready drivers for the peripherals, its not designed for beginners! The board is best used by those with previous Linux experience: the good news is you don't have to have another Linux computer to set up the CHB but you should have familiarity with shells and shell scripting, gcc, make, dmake, etc. We also suggest having had some poking around with microcontrollers such as BASIC Stamp, Arduino, AVR, PIC, 8051, etc. So that when we say "i2c" and "not 5v tolerant I/Os" you can follow along
+**The CHB is not in any way officially supported by [[http://www.chumby.com/|Chumby Industries]]! Chumby has generously offered a [[http://forum.chumby.com/viewforum.php?id=20|Forum]] and [[http://wiki.chumby.com/mediawiki/index.php/Chumby_hacker_board|Wiki]] where they will try to share information but there is absolutely no hand-holding tech support or guarantee that the CHB will meet your project needs. Please do not contact Chumby directly either by email or phone for help with your CHB. If you have questions, please post to their forums to receive help from others and the occasional assistance from a CHB developer.**
 ====== Powering the Chumby Hacker Board ======
 ===== Power jack =====
+{{:chumby:chumbypsp_med.jpg|}}
 The Hackerboard requires a **regulated 5VDC** power supply, positive tip, via a [[http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=CP-035D-ND|3.5mm OD, 1.4mm ID barrel jack]] (sometimes referred to as a 3.8mm or 4mm connector). [[http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=CP3-1003-ND|To connect you will need a matching plug, such as this]]. We suggest [[http://www.adafruit.com/index.php?main_page=product_info&cPath=46&products_id=276|a regulated switching supply]] with over 1000mA output capability. The power required by the board itself is not that high (100mA? //check this//)  but if you plug in a Wifi dongle into the USB port, or an LCD into the LCD expansion port, the power required can easy climb to a 1000 mA. Since the connector is the same as those used in the PSP, you can use [[http://www.adafruit.com/index.php?main_page=product_info&cPath=46&products_id=276|PSP power supplies and chargers]]!

+===== Connect =====
+{{http://www.ladyada.net/images/arduino/rebootdriver.jpg}}
+Plug in your FTDI cable, and install any drivers. See our instructions for driver installation for [[http://www.ladyada.net/learn/arduino/lesson0-win.html|Windows]], [[http://www.ladyada.net/learn/arduino/lesson0-mac.html|Mac]] and [[http://www.ladyada.net/learn/arduino/lesson0-lin.html|Linux]]
+Once the driver is installed, verify the COM or tty port. For example, the COM port for our FTDI cable is COM34 (we have a lot of FTDI cables!). Open up a Serial Terminal program and connect to that COM or tty port at 115.2Kbps without hardware handshaking
+{{:chumby:termconnect.gif|}}
+Connect a 5V regulated supply into the chumby and your FTDI cable so that the black wire lines up with the **GND** labeled pin
+{{:chumby:serialconnect.jpg?500|:chumby:serialconnect.jpg}}
+You should see the following on your terminal:

+Hit return a few times to get the shell!
