At the beginning of the week I built the first fully functional prototype.
with the StepUp hooked up
The program was adapted from me so that can be selected via the solder bridges different Expires. (eg is constant pulsing or strobe effect)
this is thetest configuration. (the audio-cable is a little bitlong) My USB-Powerbank is about 2200mAh and after two hours its still working fine. When I put both sides to 100%, the whole thing runs about 750mAon thebench.
2200mAh / 750mA = 2,9333h After three hours everything was still working fine , too ;-)
At this weekend I've found a little time, to write a "clean and smooth" program. It was done in Bascom (as I already said).
The programm has been kept very simple:
It starts with the lowest PWM on both sides. Both sides are enabled at the start. From this point, you can disable each side by pressing the assigned button. And you can adjust the brightness by using the up- and down-buttons. If one side is turned off, only the other side is set.
So the both sides can be adjusted in every PWM-setting you want.
The RGB-Led shows the status of the control panel:
green: it's operating
red: reached upper PWM-level
blue: reached lowest PWM-level
Everything ist powered from a poor USB-Powerbank ;-)
Here are a few test photos
with normal flash
with 20% PWM - both sides
with 100%-PWM (the camera has turend automatically into "overdrive" ^^)
