[WITHDRAWN] tekwyzrd's entry for the 5th annual blf/old lumens scratch made light contest (handmade)

:+1:

Several pounds? Yeah, hang it on your belt, right next to the BLF GT! :stuck_out_tongue:

Currently waiting for delivery of an additional reflector and lenses from another member. Still debating the emitter. Conventional logic is the smallest die but I want to do something different and am seriously considering a mt-g2 to produce something more useful than a pincil point beam at long range. In a single lens light such an idea might be foolish but with multiple lenses and recyclingā€¦

part of post deleted - after thinking about it I decided it was inappropriate

Theres nothing wrong building a light around the MTG2.

All the best looking after your mate. Its a cruel horrible disease.

Ordered another lens from surplusshed that may or may not be used for this project. If not, it might work well for a S2 or similar as an aspheric or zoomie. PCX 19.8mm with a 17mm fl which results in a f number of .85858585858586 rounded at 15 decimal places. If I use a calculator with even higher accuracy I suspect the string of 85 will continue. I wonder what this lens was originally intended for.

I received the spare reflector today and am extremely disappointed. Unlike the previous this oneā€™s inner surface is hazy with obvious rings. A total disappointment and I will be contacting the seller to express this.

Still waiting for mt-g2s from intl-outdoor. Paid for tracking number but it was not provided and no reply to email asking for it.

85mm 78mm fl lens from surplusshed had a big shell (a bit over 1/2ā€) at the edge and included a note ā€˜if you canā€™t use it let me knowā€™. Iā€™ve been debating this and though the beam wonā€™t hit this point itā€™s still disappointing to buy a lens and find after delivery it was damaged but they sent it rather than contacting me to describe the problem or offering a discount - $16.50 shipped is a bit much for a damaged lens. Hoping the 19.8mm 17mm fl lens will be ok.

Sorry to hear about the bad reflector. :frowning:

Looking at the reflector again today itā€™s not bad after all. Iā€™m trying to understand why it looked so bad yesterday but today with the exception of a couple of flecks of dust or other debris it looks nice and smooth. The only thing I can think of is yesterday I didnā€™t remove it from the plastic wrapping and might have been seeing light through the wrapping in the reflector.

Thats terrific news tekwyzrd. Onward the build goes. :slight_smile:

The 19.8mm 17mm fl lens was delivered today. Still waiting for the emitters. When they arrive I will shave the dome on one and start testing the reflector and lens combinations.

Progress delayed awaiting torx head set for dis-assembly of hard drives to be used as source material.

Torx set received and I disassembled a few drives. On my second attempt I was able to solder a lap joint between two hard drive platters using 73-27 paste solder to create a surprisingly strong joint. I plan another test with lead free solder. Thanks to this my concept has changed and will use a group of platters from now past their prime hard drives for cooling fins. Scrapping covers, housings, and boards will provide funds needed for additional materials like copper tubing and additional solder. Photos coming soon.

This sounds totally intriguing. Looking forward to how this transpires. :slight_smile:

Great to see that you are still in the running, & canā€™t wait to see the build pictures :beer:

Very unfortunate, stay strong there :+1:

I wish the best and fast recovery of your friend!!
Weā€™ll be looking for your project afterwards :wink:
ā€œKeep your head up, keep your heart strongā€ :+1:

Sorry to hear both lots of news.

Sorry to hear this. Best wishes to your friend, too.

Best wishes from me also tekwyzrd.

Sorry to hear about your friendā€™s hardship, & good on you for your support :+1:
