OLcontest, modified light: 20cm fresnel lens thrower

The Flying Dutchman? :wink:

Ver licht? :stuck_out_tongue:

I had to finish it today, so hereā€™s the final stretch.

Because the star and the batman projections were not what I wanted for this build, I tried a little spider. The shape was too difficult for the fretsaw, so I went for etching a thin copper sheet, for so long that the copper was eaten through by the FeCl3. I took a long time, and the cutout was not perfect, but the result was rather nice.

Still, this was not the final version. But here are some pictures. Both are at about 40 meters.

I like the spider.

Maybe a slot for interchangable shapes

Thatā€™s AWESOME djozz. If I saw that in real life, Iā€™d be thoroughly creeped out (I hate spiders!)

And now for the finished light!

Meet the Vir-O-blast C19. My pinstripe is certainly nowhere good enough to apply for a job at RR (link), but I still like my paint job.

The vir-o-blast c19 will not infect you, or cure you from anything (although this post may be the start of a new conspiracy theory :person_facepalming: ), but it may hopefully brighten up this dark winter a bit :slight_smile:

Without the virus stencil in place and with the led die focused, the throw number of this build is over 4Mcd, but with the led die defocused and the stencil focused, the virus projection does 800kcd, still a significant number.

And some pictures of the finished light:

Tonight I will do a small video showing the zooming action, and still some loooooong distance shots showing the 4Mcd need to be made.

I love it! :beer: :+1: :slight_smile:

You know, somehow I missed this entire entry - lord knows how. It is amazing. Personally I am not going to be happy until I see a BLF logo in that thrower lol! (kidding of course)
fantastic work, well beyond anything i could muster! Good luck!

Cool :+1:

Regards Xandre

Awesome build, Djozz! :beer:
Iā€™m thinking about numerous images to be projected using that flashlight.

I like it ! :+1:

Haha that little viral addition takes the cake :smiley:

Looks great!

I love how ā€˜simpleā€™ it is on the inside! Very clean build. :+1:

There is even no driver, the battery is wired directly to the led. I was contemplating building in a fuse for safety but that would cost current, I fear too much.

Fantastic build

A sort video from the balcony without the virus stencil to show it is a zoomie. My 10yr son is the camera man so it is shaky, and the focusing of the my phone is a bit lousy but you get an idea. The big trees are at 30 meter, the very end of the square is 125 meter, the square is no match for 4.2 Mcd.

I bet heā€™s proud of his Dad! :+1:

Well, he already takes his dadā€™s weird hobby with a grain of salt Iā€™m afraid, no unreserved admiration :expressionless: . But he does like this one!

Great Video :sunglasses: , it brings your light to life. :+1:
.

Uau, I hadnā€™t seen the final version, this is uber cool :sunglasses:
Liked the name of the build too! Beware, you foolish virus :smiling_imp:

Well done :wink:
