Hello there,
i am an excited user of Rockbox on both my iPod Mini as well as my iPod Video - as well as a noob on hardware-related topics concerning rockbox, so please forgive me if my idea is foolish or was already discussed.
I am planning a little diy-project, whose main issue at this moment is an intervalometer, something that closes a circuit constantly over a certain interval of time.
my idea was the following, as i thought that this would be the cheapest (and somehow most unusal) idea:
Writing (or using if already available) a simple plugin for rockbox that makes use of the dock connector and the currents found there (to power certain ipod accessoires), sending that current for a short time to a transistor, which then closes the actual circuit...
i dont know anyhting about the structure (and language) used for the rockbox plugin, but i guess the main structure of such a plugin/the whole process would be something simple as this:
1) the variable T is an inverval set by the user via a simple input in rockbox
2) the plugin then waits T seconds (or equivalent)
3) the plugin sends the current via dock connector to the transistor
4) the transistor closes the circuit for a short time
5) the plugin returns to 2)
6) the plugin continues until the user presses a button or a certain pre-set count is reached
I guess programming and so on would not be a big problem for such a simple thing (even for me, whose biggest programming accomplishments would be some stupid java thingies back in my days of school), as long as there actually IS a way to send a current (or control this current) via a rockbox plugin..?
Thanks!
Rob
