After having bought some excellent blue modules from Johan i wanted to create my own blue modules as a add on for my greens.
So after having drilled and stuff i adjusted lens and placed prisms. I had a very nice beam, i was so proud.
It was 3mm at aperture and at 39m it was just 4x1 cm or something. really spicy beam.
Put nail polish on lens so it would harden and keep the lens fixed, then went on cleaning the dichros first.
After the nail polished dried i turn on the diode to find out i had a standing stripe, instead of a horizontal stripe.
I was getting nuts, later i realised that this was probably because of the prisms weren't there, but i was getting confused then at that moment.
Then i glued the first prism straight like Rob always does in his modules and then the second.
Then shit turned sour. i wasn't able to get a nice straight dot and every time i readjust the lens it was cool and when taking the screwdriver out you saw the dot growing at 39 meters distance.
When i pushed in the lens it was ok, so i decided to push in the lens while epoxying it shut.
Well that sorta worked, but it was still not to my liking, lot's of strange effects in the beam.
Then i found out i had the second prism glued wrong way around, no problem got 2 pairs so glued another prism in place and immediately things got better.
But now there was so much glue , nailpolish and stuff around that probably lens got dirty as well a bit...
But now i have a similar profile as Edisons modules only with a little more scatter.
Am now thinking wheter i will switch my other edison modules to such driver too and use a die4chill to cool it (or place a metal plate in place of the TEC and use it aircooled).
Since Edison did an excellent job of creating this nice blue module, that will take out the hassle of adjusting ;-)
Hat's off to you guys that build your own blues. But this is part of the learning process right ?
Fucking it up to make it better next time. Well, i am a bit disappointed i could get the result i had in test setup since that was ab-so-fuckin'-lutely brilliant.
But i have a blue now and made it myself, and better yet, when turned off it leaks NO blue light since the driver i used has blue suppresion.
So i think the drivers with suppression circuit have the future.
