![]() ![]() The end where I'm shining the light into will have a glass/plastic lens over it that can accomodate lights up to 4" and establish a platform for the light to rest bezel down on and be completely exposed to allow a fan to keep it cool. The entire contraption will be strapped/bolted onto a wood base. Total parts used cost $34.40 before taxes: elbow to further reduce the likelihood of any direct reflection making it to the light sensor and ended up with this: I've read about the PVC U-pipe idea but decided to add an extra 90deg. allow light sensor to be easily removed for other measurements ![]() not be affected by ambient lighting while logging is in progress provide stable platform for light to rest on while doing runtime / logging and light must be exposed to allow fan to cool it allow consistent repeatable measurements must accomodate bezel head up to 4" in diam So I came up with this idea based on the following criteria: Also, based upon what I've read, I felt tweaking the baffle has been one of the trickiest parts to calibrating it properly. While I can do a ceiling bounce, there are usually too many factors introduced (beam shape/intensity chief amongst them)įor the latter, I've been meaning to build an IS but don't like the idea that there would not be a stable platform/holder for the light while I'm taking measurements (especially for runtime logging). PWM readings (building audio cable connected to solar cell and will use a PC soundcard oscilloscope program Two things lacking from my reviews have been: ![]() Wanted to throw this idea out to the experts, so please humor me if you will. ![]()
