TO Clarify besides giving nkgamer1990 advice and reading material i will in no way be helping or organizing this. The source of the optics from my last GB cdbeam knows and if you want to go that route thats fine but I want zero part. MY sole intent on posting was to make sure the OP knew whats...
I came back because i was sent a mail telling me that someone was trying to do an optics group buy and I want to make sure they knew what and how to order as to get quality optics and not garbage.
I dont think there is anything wrong with telling the seller there would be a larger order later...
short answer: NO
I swore to never take part in a GB ever again. They are not very good or i am very bad with them. i think its a bit of both.
Try going to alibaba and talking to a bunch of the sellers and ask to see there current production catalogs for cylinder lenses.
Make sure you can...
I am glad to see someone trying to bring down the prices of these correction optics.
The only store i know that sell a cylindrical lens pair is Dave from LSP Lasershow Parts - 4 x mag cylindrical lens pair
And his price is 50$ and there is no mention of a coating or quality.
the first link does but you have to build it that is the only way its cheap.
The kit one costs about 110$ so i found you one.
but if you want to build one it will cost 16$ for the arduino plus like 10$ for display and then maybe a few extra bucks for psu
i know its not the super cheap way you were hoping but its sure a time saver vs building you own pcb and code or trying to mod others.
But it can be done.
the first link even has some code to make it.
So check it out and see what you can make.
heck maybe if your tests go well maybe a few others...
there was a site about how to use a arduino plus digital calipers to decode the numbers.
i think those slides work the same way.
did yours not come with the ones like the auction?
you can build one im not sure if i have seen a x y z one but i have seen a single.
Also there is more precision i...
