What did you mod today?

Got most of the work on the giveaway light & diffuser done

.

Looks awesome CRX!!! :+1: :+1: :+1:

I’m surprized by seeing the difuser going all the way down! :exclamation:

Thanks, yeah i’m just experimenting, i thought it would be cool if i can basically fit the whole light in the diffuser and have it lit up that way for compactness.
Still working on it. :wink:

If I don’t win it :disappointed: in your 1000 posts GAW, please consider if you’d be willing to make me a similar one. I really appreciate the unique personality of DIY handmade flashlights (& stuff in general) and love brass/copper (and wood) as material.

That is a very nice compliment, thank you, i will keep that in mind :+1:

Was about to finish a 3up XP-E2 Convoy S3, but my cheap china-programmer refused to work…

Connection test gives me : “could not find USB device with vid=0x16c0 pid=0x5dc vendor=‘www.fischl.de’ product=‘USBasp’ ”

It’s strange because I didn’t change anything. Had it working on Windows 10 some days ago. Tried two different drivers, both with the above result… Don’t know if I need a new programmer or if it’s a software/driver related problem. :frowning:

I get that from time to time, usually just unplugging/replugging the usb programmer fixes it for me.

I have been tweaking my light canon, and I’m ALMOST at 1.5Mcd!!!
Sooo close… 61000 lux at 4.9m = 1.46Mcd…
I will post pics when I get to the magical 1.5!

I tried that a couple of times. Don’t know what else to try. Will ask google, hopefully right questions…

Nice achievement Enderman!!! :+1:

USB 3.0 ports give us trouble with printers and such at work sometimes…especially with Windows 10…I’d make sure it’s plugged into a 2.0 port.

It’s USB 2.0. Don’t have a 3.0 port on this machine.

:smiley: :smiley: :smiley: thanks!
I am very excited lol

I’d be quite excited too, Enderman! Must be a crazy beam you got there… :smiling_imp:

OK. I managed to get my programmer working again. YAY!!!

I’ll explain the steps I went through in case someone has a similar problem it might help…

  • Opened the device manager, found two USB Universal Host Controllers show the yellow exclamation mark sign (Code 43 error)
  • Right clicked and deactivated (not deinstall) both of them
  • Restarted my laptop
  • Went back to the device manager, right clicked and reactivated them again

That did the trick. So if you experience similar issues, I hope this helps and it’s as simple as that for you.

Gonna flash some drivers now. WOOHOO! :partying_face:

1.5Mcd!!! :exclamation:
Waiting for the pics! :+1:

Truly awesome Lux numbers, looking forward to seeing pics of the light and set up.

For what it’s worth, Canon is a registered trademark of a camera company, your use of the word would be cannon, as in long thrower. :wink: (just a bit of OCD coming through, right is right, after all)

Wouldn’t a light “cannon” project a large diameter beam, like the old aircraft search lights? Maybe I need coffee… sorry

Wow!! Congrats on this site unseen project! Try a reading at 10-15 meters, betcha you will get over 1.5 easy... I think every light I've tested at 5m got a nice little bump at ~12m, plus it's actually more accurate.

I agree he meant “cannon” (simple typo) but “canon” is not just a camera company:

Sk68 died a smoking blue death (single mode with liion cell) so I pulled out the pill and reamed the hollow shell to the OD of 1/2” copper pipe(.625”). And made up a copper insert. I might go old school and direct solder an XRE since a sinkpad would raise the die out of focus.

Thanks guys :slight_smile: I actually made a mistake in my calculations, there’s a thing called etendue, and due to this the formula 1/r^2 doesn’t directly apply to my light because of how it is almost collimated…
The farther I take the measurement from the light, the more lux @ 1m I get.

The correct way to calculate it is by using this tool: Candlepower & Divergence Calculator For Uniform Beam Lights or you can do a bit of trig to manually figure out the distance behind the lens
This means that I’ve always been underestimating my measurements, and I might be getting actual candlepower in the tens of millions….
I need to make new measurements at a longer distance, and measure the diameter of the spot to figure out the real number, so hopefully in the next week I can actually tell you guys the real numbers :smiley:

Yes, but there are so many “light cannon” named lights I wanted mine to show up on google search, so I named it “lightcanon flashlight” so that it is pretty much the first result :wink:

SHHHHH let’s pretend it is what I said above

The last emitters I bought to dedome died under direct drive, I think they were U3’s?

What bin of XP-L’s are known to be more “durable”? I know the W2’s on Aliexpress are an option, but I’m not sure I want to spend that much yet
