What did you mod today?

I can’t see anything on your post, only the word “this”. Something wrong with my browser? Other pics work.

The first light with my F-8 driver for dual cell setup.

I used a Convoy M1 host and installed my F-8 with solder pads connected for 4 x AMC7135 and the FET on PB3 so I don’t have to HVSP reset the MCU prior to each flash. Once I’m happy with the firmware I’ll shift the connections on the solder pads to put the FET on PB5 and connect the currently unconnected remaining four 7135s on PB3.

In with my favorite LED, the 5000K MT-G2.


It’s a nice light, pretty bright with FET on full blast and useful lower modes using different amounts of 7135s. I haven’t fully converted my firmware to off switch only lights so all settings are currently coded, but that’s work in progress.

Nice! You got skills.

Well, I now have a FET driven Thorfire S70. It kind of happened by accident. I sliced the dome, but apparently my solder joints stuck out too far, contacted the reflector and fried the driver. Pulled the original driver, stripped the components to use it as a battery board. Overall I am pleased with how it turned out.

The M2 is a nice MT-G host.

todays little mod was to shorten the battery tube of a convoy s4
to take 18500 cell , trying out my new/sh toy lathe

Today, I started a new triple : S30RII !
I plan to use 3 of the 10 219C that I ordered on RMM at $2/ea.
Well, today I only received my 3XP boards and 10507 optics from Intl Outdoor.

I had to drill in the center of the stock LED shelf :

The copper pill, made of three 3mm plates (saw, file, drill…)

The Noctigon had to be reduced to 18mm in diameter :

Dropped in :

Annnnd that’s all, the bezel and stock lens + u-ring will then be screwed to close it all.
The height is exactly the same as stock copper board + optic with a 9mm height pill.

Very nice. You sawed and filed the copper by hand? A modder after my own heart. There’s just something that feels good about shaping a piece of copper by hand, and having it fit perfectly.

Yes, I cut some 20mm square, drill a hole in the center, cut a rough circle with a saw and file it fine. Then I mounted it on my drill, and filed it again while turning

Nice combination of host and triple! About the board filing, check for a short between the metal core and the led-minus (I remember some less favorite hobby-moments)

I always clean up the edges with very fine emery paper to get rid of any rough edges or tailings that could cause a short.

I modded a hugsby ml-8. After wrapping the head and tube with rubber i was able to break the thread lock glue with a small pipe wrench and a vice. I took the stock pill and inserted a c8 pill in it to hold my driver (a dd 6v zener mod). On the top side I punched out a 20mm copper disc 2mm thick. polished both sides, added some therm grease, and slapped an XHP70 on top. Soldered it all together and whallaaaa. The factory OP reflector made for a nice tight beam with good unblotched center. If anyone is interested I can take pics and post em. I am making this post because when i did a search for such a couple weeks ago I found very little. So maybe it will be of interest to someone. :slight_smile:

I didn’t mod anything today, but I did a lot of deep thinking and modding in my mind.

Very interested. :slight_smile:

I think you’re one of two that have been able to open it. No pictures of the internals have been posted afaik.

God work on the Hugsby ML-8. I know I promised pictures of it apart a while ago, sorry totally forgotten. I am currently working on adapting a smo reflector. I also had to order new o-ring for the bezel. Original was like soft plastic and did not seal properly.

It’s called pre modding, bar napkin mulling, or drinking, depending on your emphasis at the time. I’m an avid practitioner.

Yes you did. You are modding your plans for modding :slight_smile:

I’m modding my modding plans all the time! Unless the family interups that and mods the amount of time I spend modding my modding plans.

Today I build my 4th C8 with XP-L HI, it’s just another C8 build, but this time I used DrJone’s magnificent H17F driver.

The H17F is beautifully designed and the programming possibilities is just mind blowing, the most amazing feature? A PID regulation that actually works, watching the output go up and down on a light meter is rather satisfying. I don’t have a data-logging light meter yet (ordered the UniT 382), but I couldn’t notice any output step during regulation, it happens very fast and smoothly. We’re talking about zebralight-level PID here…

Compared to a regular FET+1 the amps in turbo only dropped 0.16A which is really nothing for 5.3A+ on a single LED. I would confidently use this driver for any triple XP-L build, the FET is tiny, but it can handle some serious power. :wink:
