Thank you Texas Ace for doing it. I think it’s very valuable to have a set of cubes which measure the same spread around the world.
I’m not into this stuff deep enough to buy one yet (and recognise that I may be losing my only chance), but I love it nevertheless.
I plan to get some PVC quotes tomorrow for both the normal and larger size and hopefully see if I can get anymore diffusing sheet (If I offered the larger tube option I would need more for sure).
Saturday I plan to take a trip to the laser cutter and 3D printer to get a quote on those.
I have an idea what the prices will be but I need to confirm.
I am also talking to a few suppliers about getting express shipping on the lux meters so we don’t have to wait forever.
Once I have all of that nailed down I will start taking payments, most likely this weekend.
Yep, pretty much. I just want to nail down the final details to make sure there are no surprises before I start taking money.
This is much larger then I first planned on and the costs are higher as well. So having to re-figure some things and make sure I can get the quantities I need.
Boaz is selling DC-Fix Here and he has mentioned that he has some other materials including some that are thicker/stiff that he needs someone to test. Maybe you could help him out with testing, and it might be similar to what you’re using for this tube or even the same material. I don’t know what price you paid for yours, but I think you should check with him.
Yeah, I got my DC-Fix from him myself. I was planning on using it for the sphere but it would of needed a separate piece of glass to mount it on.
The biggest reason I want more of this particular diffusing sheet is that stacked in the right order it gets the sphere within about 5-10% off the bat, which is much easier to fine tune then something that is further off.
I am pretty sure I saw another half sheet of this on a shelf when I got this but I didn’t worry about it since I didn’t think it would be needed. I plan to stop by tomorrow and see if it is still there.
What about using a 6 inch to 4 inch reducer on the regular lumen tube and then have a correction factor specifically for using that reducer?
That way it keeps the cost size and shipping weight down and only adds one extra piece to be used on rare occasions. The rest of the time you have the normal three and a half inch inlet and can read the lumens directly off the meter.
I have considered this as well but it would have to remain attached at all times, the calibration would change too much to be easily compensated for when it was added or removed I think.
Installing it on top would make it top heavy and I don’t think it would sit flat anymore.
Using a 6” to 3-4” 90* bend is another option I am thinking about but talk about expensive!
I will see what the specialty place has, if they don’t have it, then I don’t think I will be getting it.
