Announcements: Camera Modification Steps…

Gateway To Space ASEN / ASTR 2500 Class #13 Colorado Space Grant Consortium

Canon A 570 IS Mods: - The following instructions will walk you through the steps needed to change the firmware on this camera to take picture every 20 seconds

Canon A 570 IS Mods: - The CHDK code was originally written by Rick von Glahn from Edge of Space Sciences (EOSS) - These steps are performed with the camera modified to turn on and off with a external switch - The steps to modify the hardware of the camera are contained in a different presentation

Canon A 570 IS Mods: - This mod uses CHDK to add autonomy to a digital camera without the use of a timing circuit or further modifications to the camera - CHDK is firmware enhancement - It only works with Canon digital cameras - Please see the following website for much more information http: //chdk. wikia. com/wiki/CHDK

Canon A 570 IS Mods: - “<ALT>” will be replaced by “<CNF>”

Canon A 570 IS Mods: - Use the control pad to move the cursor down to "Debug parameters" and click "SET" to select this option.

Canon A 570 IS Mods: - Move the cursor down to "Make card bootable. . . “ - Press "SET" to select this option.

Canon A 570 IS Mods: - Remove the SD card and slide switch to “LOCKED” Even though the card is in the “LOCKED” position it will be able to be written to via the CHDK firmware.

Canon A 570 IS Mods: - Insert locked SD card and make sure the camera is in “RECORD” mode - Power on the camera - “Default Script” and the “<ALT>” should be visible - Press the shutter button to stop script

Canon A 570 IS Mods: - With “<ALT>” showing, click on the menu to get to the “<CNF>” screen.

Canon A 570 IS Mods: - Now click "MENU” to save these changes to the configuration file

Canon A 570 IS Mods: - Turn off camera - The next time the camera is turned on, it will run the script - It will go through a series of camera setting changes which will take about 60 seconds - Then the camera will begin to take pictures every 5 to 6 seconds until the card is full

Canon A 570 IS Mods: - Sometimes the script doesn't execute properly the first time it runs. - If this happens, let it run it's course for around a minute or so then turn the camera off then on again and it should work fine - It should continue to work just fine on every subsequent power up

Canon A 570 IS Mods: - Turn on the camera

Canon A 570 IS Mods: - You can turn the camera off anytime. - If you wish to stop the script during execution just press the shutter release button and that will interrupt the execution of the script - In this way you can gain control of the camera without having to remove the card - This is handy if you want to review photos, or do something else without the script running.

Canon A 570 IS Mods: - After the pushing the shutter, you must push the print button to have normal camera operation

Canon A 570 IS Mods: - Remember, any setting you might make to the camera will be restored to factory default settings next time the script runs as that is the first action the script takes - Once you interrupt a script it must be re-run from the beginning you can not PAUSE a script and RESUME it

Canon A 570 IS Mods: - You can modify your code without reloading the firmware - For example lets change the “sleep” value to 5000

Canon A 570 IS Mods: - Power off camera - Remove SD Card - Unlock SD Card - Open CHDK/Scripts/cu_gateway_fall_2008. bas - Scroll down to end of code and change sleep = 5000 - Save

Canon A 570 IS Mods: - Remove SD card and lock - Insert SD card into the camera and power on - Pictures should be taken every 8 to 10 seconds now - I would suggest a 20 second (sleep = 16000) for 135 minute flight time

Canon A 570 IS Mods: - You can also “rem” out pieces of the set up or other functions but test first - Camera is working, it shall also be working at the end of the semester - Take good care of this camera - Thank you.
