[Review] 77 Outdoors D25 Headlamp (18650)

Alright man, how’s this? With the grips being centered, you’ll now need supports under those too. But that’s how 3D printing goes…

looks awesome, yep, will definitely need supports, but it is ok, sharp razor removes most of the marks, and they are in such location where it isn’t noticeable much, thanks gchart, again great work.

printed one from abs, I like so much better than petg, it prints so much better, no stinging, supports come off easy, and i was able to print it laying flat. layer adhesion is great. and i can make it smooth with acetone vapor, it will look like injection molded. i used hatchbox black abs. now i got more brackets that flashlights, lol

Very cool. I’ve never tried ABS. I don’t have my printer in an enclosure… that’s highly recommended for ABS, right? Is yours enclosed?

yes, i build one myself, my printer did not come with one. i seen people use reflective emergency blankets, they are sold at walmart for few bucks, some even simply put a large cardboard box over the printer, it does the job.

Could you make one for the Sofirn SP40 and sell it? The one it comes with is too tight.

i’d print one for you no charge, but i need stl file, i can only print, i can’t design one, and i can’t test it either, since i have no sp40. if you can find stl, i’ll print you one.

I no longer have my SP40, but I might be able to borrow it from the guy I sold it to.

Or… If you have calipers and can take some measurements, I can design one from the measurements. I had considered doing the same for the Convoy H1 (which I do have) if there’s interest.

Thanks for offering but I don’t have a file.

No calipers to take measurements but thanks.

The Sp40 has a flexible rubber holder, correct? So you can’t really use measurements from it. maybe you can put the SP40 in the D10 holder and see what needs to be changed. Adjust the width of the fingers, maybe their diameter and all the rest can be the same. Just a thought.

i think every headlamp needs such holder, so much more convenient than a silicone one. every HL would benefit from it, imo

I was not really interested in D10 / D25 but once I learned about D20 I started reading up….
WOW.
Guys, what you’ve done is awesome. Especially gchart.

I did a barebones build of Andruil (Emisar D1 target, Attiny85), removing literally every feature that could be removed.
Under 3K. Still has not-so-easy to remove bells and whistles like stepped ramp and LVP.
A very comfortable config without thermal regulation is under 4K easily but enabling this single feature makes the size jump to almost 5K….

Agro, you want headlamp without LVP ( low voltage protection) and thermal protection ? :smiley:

Thanks man! The choice of RampingIOS over Anduril was for two primary reasons:

  • RampingIOS is pretty much in one single code file and as such, was much easier to port instead hunting and pecking across 20 files (or however many Anduril uses… its a bunch IIRC)
  • In the SOIC8 footprint, the largest memory offered is currently 4KB. I knew I could get RampingIOS to fit, but I figured Anduril would be too large no matter what I stripped out. :person_facepalming: Now I’m going to have to revisit this and see just how many features I can get packed into a 4KB build. Another thought I’ve been mulling is making an adapter PCB to mount a QFN chip (like the attiny816, 1616, or 3216) onto a SOIC8 footprint… that would be extremely versatile.

If I can find the time, I’m really hoping to get Anduril ported over to the new tinyAVR 1-Series for the OL Scratch Build contest.

i ordered xpg3 on 16mm star, some gaskets, and reflectors, will try to see if i can get it focus properly. i like d25 but its bad beam profile is a turn off.

Adafruit makes a breakout board/adaptor available through Digikey. $2.95, but shipping and minimum order will eat you up. If you don’t need the wire attachment through-holes, you could probably design a sheet and have them made somewhere. You can sometimes find QFN sockets with SOIC footprint, but that would only be useful in a prototype board - they’re pretty tall.


FET+1, Zebralight like or Anduril UI . 11$ shipped. If interested PM.

I’m thinking something like this:

It’s a WIP, but shouldn’t take much to complete it. I just need to make sure I optimize the pin mapping (PIC’s ADC pins to ADC pins on the Attiny, etc). Unfortunately, the minimum board size at Oshpark is 0.25” x 0.25”. So some filing may need to be done, but I’m making it such that it won’t harm any traces.
