Added documentation concerning the next iteration, called Flashlight 'B' to the main body of the blog post.

Great idea. It is good to see a practical use like this for an ePaper display. Your logo is a great touch.

Awesome project. This is something that I am going to try and implement soon, ideal if your going to a conference and should serve as a great ice breaker.

Great idea.

I did get mine out but had issues with the image conversion, so might need to see if your guide works for it.

It's amazing how long the image stays on the screen.

Mines been in it's box for 2 years or more and is exactly the same as it was when it went in there.

Great ! I searched for a while e-ink screens time ago but I have not found nothing at a reasonable price [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-02436bea-45bc-40de-97e4-e235740e8a5f/1512.contentimage_5F00_1.png:16:16]

I made some progress with a dual XM-L2 design, I'm hoping this one is around 600 lumen ballpark, with just slightly more current consumption (perhaps 1.1A at 4.5V). This uses the TI LM3410X driver chip. There is also an 'Ext' port on the PCB for connecting up an Arduino or whatever in future, for providing dimming.

[View:/resized-image/__size/776x340/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e0d6062f-c110-4f76-a11a-4f1f8d1eff81/4010.contentimage_5F00_185507.png:776:340]

For the LEDs, I've made a 3mm hole for soldering a copper rod, if it works then this is a super-cheap (and easy) way of getting the heat out.

[View:/resized-image/__size/770x649/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e0d6062f-c110-4f76-a11a-4f1f8d1eff81/6813.contentimage_5F00_185508.png:770:649]

The rear is just copper, for a bit more cooling. The two side holes are for attaching the reflector (the same part number as mentioned before), it isn't designed for this LED, but it looks like the XM-L2 dies are at identical height to XP-E, and the angle for illumination spread is near-identical too. To make the reflector fit, the hole at the rear of it will need to be drilled to 5mm.

Nice project. Looking forward to the video. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-02436bea-45bc-40de-97e4-e235740e8a5f/contentimage_5F00_1.png:16:16]

Judging by the battery and the red and black wires I would strongly advise not travelling on public transport while wearing it, based on this guys experience:

Nice project Shabaz! when we can enjoy a demo video, if possible?

Hi Shabaz,

Nice project. Since we have DC to DC converters that approach 100% efficiency you would think we could come up with a more efficient electricity to light conversion so we could get away from the constant waste heat problem.

RE: Geeky Gadgets - Star Wars vs Star Trek

ninjatrent — Wed, 14 Jun 2017 04:44:21 GMT

This is a great post. I am a huge Star Wars fan. Star Trek is one of the best sci-fi themed shows. All though I am not a true fan, I still like Star Trek.

It cannot be denied that both have inspired the minds of young engineers and scientists. Star Trek and Star Wars were both created around the time humanity took it's first steps into space.

So much of the technology we have today was once thought of as science fiction. It's amazing how the human mind can be inspired by fiction to influence reality.

Thank you for this post. I have been working on an idea for a Star Wars project. It has been somewhat challenging and I have considered seeking outside help. The idea is a toy hack. I would really like to see if it could be featured on TBHS if such a thing is possible. I am a huge fan of the show. I believe that Ben Heck and team would be the most qualified for this project.

I would like to donate the toy and parts that I have to see this project completed. And I would like the toy given away to a good home. Does anyone know if this is possible?

Nice build.

Not sure of its use. I prefer the old fashioned hand off so you can look people in the eyes to assess if they are just going to toss them after you leave.
