Lot’s of maths and theory here - I like it! Question, do you still have your post about cutting threads with a lathe? I would like to read it. Have you considered that depending on the diameter and the pitch (is that the correct word?) of the thread you might have to angle your cutting steel slightly? Otherwise you might touch the thread with something else than the sharp part of the cutting steel.
Regarding the pattern of the 7 lenses - when I made my first multi emitter light I thought about the same. I would not recommend to focus all the beams at one point, because after that point the beams drift apart again. So the best is, as Hoop already said to have them all parallel to each other. They kind of converge, depens on your point of view. The distance between the single beams will always be the same, so nothing converges there. But if you look at the surface the beams cover, the further away you go the bigger the surface and the percentage of the surface which is not overlapping converges towards zero. Does anyone know what I mean? Hell, I am bad at explaining…
Yeah fritz, I get you. If the beams are parallel then the spread of each will overlap the others but not diverge more than what us the case for each one but if the separate beams converge at any given distance then beyond that they will diverge more than individual spread.
No way guys, I am not doing ANY math for this one.
I do still have my post about threading. It took me most of a day to compose. :weary:
Yea if you imagine how laser beams would act in this scenario… they could either converge at a focal point and then diverge after that point, or if arranged perfectly parallel, would never converge or diverge. Fortunately these little aspherics are nothing like a laser beam, and make a decent usable spot. They should overlap pretty well in parallel and make a single hotspot, barring any serious deviation in form.
Um, even a laser beam grows with distance, so multi’s would converge to cover a common area at some point… just much further down range. MUCH further.
At least, the laser’s I have show a larger hot spot the further away the hot spot lands… my 200mW green laser shows a substantial hot spot at 2.2 miles, probably 12’ across. My 3000mW blue laser won’t even reach that far.
Yea that’s true. My hypothetical perfect laser beam anecdote wasn’t too helpful.
The lasers would eventually appear to converge into pretty much a single spot due to the overlap. In the end the circles are so large that they overlap like so:
That should illustrate what fritz15 was explaining.
Those drawings look super cool Hoop. Who’s the man at the machine as I dont see a hat wearing old dood with a cigarette hanging out of the mouth? The end caps for the battery carrier, are you making those yourself?
Excitement is in order here folks!!! :+1:
Well fans, your seeing it here live! It looks like he actually hit the ball out of the park. :student:
Very very, nice work indeed!!
I bet you guys thought I was a cranky old dude but I’m 31. Yea, I’ll be making the end caps from G10 sheets. The thicker portion will be cut from 1/16” sheet and the thinner portion from 1/32” sheet. 1/32” deep pockets will be cut into the 1/16” thick G10 to contain the brass contacts.
Thanks jhalb. It doesn’t technically “exist” yet, but don’t let little details like that curtail your enthusiasm.
