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).
