It opens the transistor, drawing the collector to a low 2) I guess a 1k should be OK but if you have an 850 or a 1200 that would do fine 3) I think any regular NPN transistor would do, like a BC547 4) If you ask me, the description says NPN transistor, not PNP Your TN4033 would not work coz it is a PNP transistor. Get a BC547 for a few pennies and you'll be fine @lolo

Your TN4033 would not work coz it is a PNP transistor.

HELLO!! i have tried to do the same, following your steps but to me it didnt work, could you answer me this questions please :D
1)”Note in the code, that the transistor is inverting.” what do you mean by this?? is inverting the polarity??
2)what resistor is the useful one? wich one did you use?
3)what is the number of the transistor that you use??
4)why it has to be a pnp and not a npn transistor??, i have several npn on old circuits and only one pnp that i use to follow your instructions, but i just can´t figure it out why is not working for me

i was tryng with this transistor:
http://www.datasheetcatalog.org/datasheet/nationalsemiconductor/DS013155.PDF

and with two resistor one of 850 and the other of 350, as 1200 was what i believe you use from the color code on your schematic

as i really don´t know much about circuits, i´m just a poor filmmaker
please help me :)
greetings from Southamerica!

But why do you not use CHDK with an timelaps script instead? Hello, nice work, from the technical side of view. But why do you not use CHDK with an timelaps script instead?
