6th Annual Scratch Made Light Contest - Flashy Mike's machined project

On my laptop I can see all the pics.

On my desktop, this is what I see:

Thanks! I guess I found the problem, all 3 pictures visible now after reload?

Yes, visible for me.

Great ideas. One of these day’s I’ll get me a 3d printer. It’ll be fun watching what you can do with yours.

Strongly recommended!
Its kind of zen watching the printer.

A better approach for the retractable reflector, I guess. This one can lock at any height and only needs about a quarter turn for locking.
The outmost tube represents the casing, so only the inner 2 tubes make the extendible part (for about 9 cm currently). The white dot in the center of the printed inner tube are the remaining threads of a printed M3 screw, made of PLA, which I broke during tests. Not unexpectedly, though.

Made progress with design. The upper half of the casing, the retractable reflector and the bottom plate are almost finished and printable, the lower half of the casing still requires some work in the inside for the electronics compartment. Here are some new renders, size of this light is 10.2 cm in diameter with a height of 5.6 cm (closed). I consider this light a pretty compact camping lantern.


It’s looking good :wink:

Updated electrical specifications:

I’ll probably use three SST-20 3000K LEDs. They should produce a nice warm illumination, so I discarded the idea of additional red LEDs. The LEDs sit in spare Convoy S2+ reflectors which I have lying around.
The switch is a reverse clicky to avoid current drain, since this light might not be used most of the year.
Driver will probably use 8 or 9 AMC 7135. The copper or aluminium plate in the middle of the lantern protrudes 3 mm, this allows a surface area of about 9 square centimeters exposed to the air. Hope this is sufficient cooling for 3 amps with this LEDs. If not I still can use less 7135.

I’m still thinking about the charging modul. I would like to use USB-C but I haven’t found a reliable source.
And I need a rubber cap for the cutout of this charging module, haven’t found any source yet. I don’t even know the proper english term for this component.

Looks great :+1:

@Flashy Mike, have you thought about using a TP5100 with a USB-c female breakout board like this:

This would work very well for charging the lantern, as it is more efficient that the TP4056, supports higher charging voltages, and would work with a USB-C female breakout board without any trouble since the current draw is predetermined.

For a rubber gasket/O-ring, I do not know though. I’ll have to do more research on the subject.

Will have a look at that, thanks!

Looking great! :+1:

Driver design is finished and sent to the fab. Two channels with 1x7135 and 6x7135. Has pads for my programming adapter, of course.
Will post new renders soon.

Oh, the light shields its own power switch when closed! Clever.

What I have ordered so far:

- SST-20 3000K high CRI LEDs on MCPCB

- o-rings in different sizes

- nylon screws

- circular neodyme magnets 20x2 mm

  • 5mm RGB-LED for status display

All from China, I hope everything arrives in time …

Looking good FM. :beer:

As promised more renders, also from the inside this time. I really love doing this renders, but I’m also afraid how the real 3d prints will compare to them. Perhaps there should be a category for virtual lights only … :wink:

The lighthouse:

Bottom of the lighthouse with o-ring and cut outs for wires:

The electronic compartment in the lower housing:

The bottom plate with neodyme magnets:

Reflector with retraction system (hard to see in this renders but the reflector is slightly conical shaped):

Lantern closed (LED is RGB) …

and open:

Very nice renders! I agree, it’s gonna be very hard for you to compete with that. We need a new category. :stuck_out_tongue:

Looks amazing. You have certainly put a lot of thought into this. :+1:
