Dammmm I wish I would of seen this earlier! I have all the parts in stock to build it, but no time to print it as I am leaving in the morning ! but its on my first thing to print list when I get back! lol Nice design well Done!!

Do you have an approximate cost for components?

Really professional!

Hi , Can you precise what was the speed print.
I'm very surprise about the 4h23
can you explain us a little bit more about this
Thank you

I used the default makerware speeds; 90 mm/s on all fills, 40 mm/s on bridges and outlines, 150 mm/s traveling. The replicator 2x is generally a fast printer, but like all printers, the faster the speed, the lower the quality of the print.

Anything new on this project?

Guys over at budgetlightforum.com could definitely hook you up with some ideas and/or drivers (tinkering and making flashlights is our hobby ;) ). Heck they may even be able to design you a PCB with multiple XML's on it https://oshpark.com/shared_projects/hZGiHT7T

Nothing new to report for now. I simply do not have the extra funds currently to move things along. I haven't forgotten about the project, it's just on a major hold for now.

Can you provide a link to a suitable driver for this design with 3x 1w led's driving from a combination of 18650's?

What degree led lens did you use

It's a frosted lense with a 14.3° illumination pattern

Do you have a list of the type of driver I need for this light

I use a boost driver since the battery(2x Li-Ion, 18650 cells) voltage is nominal at roughly 7.4 and the combination a of 3 x 1 watt leds ( Cree XPs) in series yields something like 8.85 volts. Unfortunately the board I was using has been discontinued; I am on the search for something new. Whatever you use it needs to be relatively small to fit behind the heatsink.

Actually you could run them in parallel and use current regulators to run them (amc7135's to be exact) you can stack them for more current output as well. (this design will use 4.2vdc (regular single cell LiIon 18650, regulate voltage down to 3.3vdc (the Vf of the led's on 3 channels and provide 1.5A of current to each channel, with the ability to PWM down from moonlight mode to full power depending on the programming of the ATtiny13 MCU) https://oshpark.com/shared_projects/eblIPvqT

Do you have any of these boards available?

Yeah sorry bout that; been meaning to get those up. They are now posted.

Can you please split up the parts into different .stl files? It would be nice to be able to print the individual files if one part does not print well.

where are taken the pictures : Yorkshire ?
Nice lamp.


Photos are from Great Expectations Cave

Hi ;-)
Yorkshire or not ?

No, Great Expectations Cave is in the USA.

Looking forward To the schematic! I would even love to boy a kit!

Any change on the parts? Do you have the schematics and the parts list for the LEDs?

Still gonna be a week or two before I get something posted; I just haven't had the time to put everything (parts, instructions, etc) together. Sorry for the delay.

That's too bad, I was hoping to print one for my brother for Christmas. We both worked at a Copper mine in Michigan's Upper peninsula and used out icon headlamps while we were underground.

I got a few things posted; this will at least get ya started.

Yeah I have been a little crunched for time lately, but I am planning on posting parts, instructions etc

Love your design. I'd like to make and use it on an upcoming trip. Do you have a part list for the electronics? Like the Zebralight mount too
