Hello there, lpf.com watchers & readers,

once again I’m back today to share yet one last 445nm build (can’t have enough of them, right:D) with, to be displayed here in the Review forum section. It’s a damn long overdue one, since I happen to own the beamer since January this year. This time I type more words for the drama to come and as usual let the gallery guide you through the jungle;).​



Days of future past



As the title states, the object of my photographic curiosity was the Groovy laser host with blue multimode inners, cooked and presented by on of the skilful forum machinists, mrcrouse (aka Mike, just like me:D). Just as a quick reminder for all of you’s, here’s the link that depicts the original design I personally fell in love the 1st time I’ve spotted it (among many others):


http://laserpointerforums.com/f44/feeler-custom-2x18650-hosts-80235.html


Eventually, the attention of the new design line started to rise after the proper multimedia presentation:

http://laserpointerforums.com/f48/mrcrouse-s-custom-hosts-picture-heavy-84563.html


At that wild stage when I’d jumped pretty much onto any eye-catching 445nm power laser, not to mention how I prefer clean & simple design, add the shiny polished factor to it, I contacted mrcrouse, who kindly recommended bloompyle as a builder. However as he apologised to me not to be the one who composes the laser (personal life & other probably gas lasers elated projects), the final choice went to scumbagatheist. Back then I didn’t have a clue it would take more than 4 months to finally enjoy the Groovy with my naked eye. Long story short, SBA had to deal with serious private life situations, some of the members who were in touch with him might know. I respected it and let it run as it was, desire the fact money was paid end of August. After all he managed to steal some time for perhaps one of the last laser building jobs while he was active in the forums and managed to customise the laser to his best judgement just during the month of December 2013. I can describe our mutual email communication as friendly and open-minded as it only could be, no complaints whatsoever.

Finally the day of delivery in January has come…

…and the Groovy landed in its full glory. As an (currently already former) owner of the Zaser laser, I wasn’t much surprised by the size of the host. Dimensions are very similar when comparing them, most remarkable visual differences occur in the body shape (4-lines tube vs. clean tube) and head compartment (bulky Groovy/better heat dissipation vs. thinner & cleaner Groovy). Yet the bright future of the shiny beast was in jeopardy on the very same day I’ve started to use it. The new “precious” soon developed one major issue: the spring switch inside the click button became very loose and pretty much malfunctioned:(. In real life the laser went on full time for me as it was stuck in such a position. Another smaller issue I managed to tweak myself was the G-2 lens in the focus adapter to carry out cleaner dot projection. SBA’s advise to contact mrcrouse was placed straight away, he as the original designer provided me (for a fraction of a charge, kudos to him!) with 2 extra spring switches within cca. next 2 weeks.


Only a brief technical information must be mentioned before the pic fun starts. I’d quote SBA himself here, actually taken from our last email exchange: “You're laser's specs are 450nm @ 2.3A and running at 3.1A stably.” What I can add (although not 100% prove) on top of it, is the following information:


9mm 445nm lens (DTR)
X-Boost driver (to be confirmed) set at 2.3A (DTR)
Running time of 2min on max/ 1min off min
Press-fit solid copper module
G-2 lens
2x18650 batteries



For the reference the LPM graph informs of the 3W peak the Groovy is capable of. As always, for solid and prolonged life a conservative 1min runtime is what I opt for during the lasing time.​



With the start of the February month, the Groovy finished its adventurous journey and his spell calling pushed me to progressively map the rocky road so that I could hit the finish line in about one month time later:).​


Day & night with Mr. Groovy


To sum it up briefly, I had basically two ways to pass through the Groovy’s exposition. When I had time at the weekends, I dedicated some of it to inside still portrait & close-up photography of the host parts, macro stacked in Zerene software for clearer & cleaner final look. The outdoor sessions took place during the Paddy’s weekend, weather offered me a chance I could barely let go...​

Enjoy:beer:​

Epilogue

Let us not forget the members who where draught away from the laser hobby - while they were on the peak - to unexpected life events they have to deal with. Scumbagatheist is one of the many guys from the forums I could vouch for, despite the difficult times he had to face. This Groovy pic review is dedicated to his building talent, professional attitude towards the customer and at last his friendly spirit and strong will he showed (and hopefully still maintains as I type this). An apparent special thanks goes to mrcrouse, whose laser hosts have found many good homes in the recent times, surely I’m proud to be an owner of one of his design pieces.


For scumbagatheist & mrcrouse​




…and thanks to all of you who read and browse this thread:)

Hey Gismo,
Another GREAT review. Beautiful macro shots as well. Peaking at 3W you certainly have a beast in your hands. Good Luck with your new toy

Awesome review! My eyes actually drooped heavility when I read your caption on the macro spring shot lol. Had to scroll down :p The power of sub(?) conscious suggestion?

+4 :)

PS - Were you using a longer lens for a few of the first shots? The foreground seems so close to the back and it makes the laser look shorter. Just wondering if my intuition is correct.

EDIT: In this pic:

Awesome laser there, lovely photography as always and you're right despite the life happenings he has been a very dedicated hobbyist for the most part and we all appreciate his work.

As for the build, It is just extraordinary. +3 for awesome images.

Very nice! I wish I had even half your talent for taking pictures of lasers!
+1

(Apparently I need to spread around some Rep before I can Rep you again. I owe you 1 Rep)

I sincerely thank everyone for the comments and words of kindness:beer:.

brucemir: it's a beast, no doubt about that. I'm not planning to spend $$$ on high powered 445nm's anymore, unless they become extremely cheap:D. Groovy is a keeper for me!

wannaburnstuff: fatter & shorter it looks thanks to usage of Nikkor 105mm f/2.8G I got recently. Cheating isn't allowed, I know:tinfoil:. Besides those 2 closer portrait shots are a result of originally 15 stacked sub-shots in total. Just for a reference, here is what the unstacked versions look like under ambient LED lights (with sort of a creamy appearance):

Front side view.


Rear side view.


sinner: I simply couldn't leave the Groovy laser eating the dust without giving it a proper introduction to the forum. It is meant to be a tribute to SBA & mrcrouse, their dedication was and is always worth to mention at least in a form of a personal review:).

Seoul_lasers: Exposure times were usually set at between 15-20 seconds, longer especially for the desired star effect. Looking forward to your pic production, surely you have a good stuff to offer as well:beer:.

COMMANDR, Cel, Thejoker301, BurningLaserGuy, Blarg King: support is much appreciated, gentlemen!

Just and additional info: I used Nikon D5200 with Nikkor 16-85mm f/3.5-6.5G during the night sessions.

------------------------------------------------------------------------------------------------
A few more night distance shots:). Follow the line...

Totally forgot about one extra shot taken back during Easter holidays sessions. The blue dividing sky-lake line, slightly right tilted:D.

Another excellent shot in your GROOVY series! Was this taken near sunrise or sunset? It is beautifully exposed as the plants on either side are lit up perfectly, and the way the lighting was overall, makes the entire photo very tranquil and relaxing to look at. Very soft colors. Great stuff.

:thanks:, Bruce. Shot taken after sunset, I'd be too lazy to get up for that early in the morning:D. The blueish effect altogether was brought up thanks to a short exposure of a blue light 150lumen flashlight I happen to own (not the Photoshop this time, I swear). The lake-forest-sky scenery isn't the worst background really, once I've spotted it I knew a cutting laser beam must fit in there, no matter what.

I'll take my future laser beam session in a very different environment next time, trying to combine it with some amateur landscape night sky photography. Which means spending nearly several hours out there waiting for ... whatever turns out to be good:). Right now, weather is dull and cloudy (drizzle/light rain), no clear skies in sight:(. Patiently standing by...
