Mech Modding in 2026

Got some mech adapters from jnrpop but I needed a battery.

I wanted something really short, so decided to start with 18350 host.

To match the finish of the heatsinks I choose a Stainless Steel Convoy S7, got some connectors to fit in and ground the head until it got around 7cm total length.

Next steps are creating my custom adapters and fitting some yellow DPSS on them.

Adding some photos comparing to a 21700 cell, to a short and a normal S2.

The goal was to make it not much longer than a normal host.

Looking good.

Thanks DTR!
All to try matching the heatsinks I got from your shop!

Now the collection is composed of:
- 405nm
- 450nm
- 483nm
- 494nm
- 513nm
- 637nm

Planning to fill this 7th spot here with 660 or 670nm (if I get an extra adapter) and the 8th with a slimmer battery.

Unfortunately my custom battery with 24mm did not fit the case (originally for 21700 cells), so working on a plan B…

Also got extra heatsinks this week for the DPSS range that I’m planning:
- 532nm
- 545nm
- 560nm
- 573nm
- 591nm (or was the module 589? Dunno)

Those will be based on a 24mm “heatsink” adapter that matches my battery diameter.

Used this same heatsink to make a 510 thread > Convoy S2+ head adapter just for fun.

For the DPSS the 22mm laser heatsink will be electrically isolated from the adapter/host.

Tapped and cut a piece of polycarbonate tube, hammered very easily into the 24mm adapter but the heatsink did not screw until the end.

After a little sanding it now fits perfectly without any movement.

571nm module and some custom 7135 boards are ready to be installed soon.

Placed two 300ma 7135’s into a board with some decoupling caps, wrapped everything in a layer of kapten and fitted into the heatsink reamed to size.

The heatsink and “focus” ring are isolated from both the module and base adapter for reducing short risks.

As always with yellows, it looks green on all photos

Got some more batteries

One is small enough to be stored with the modules on the case, it comes with a 18500 tube that is similar in size but I don’t have a battery cell in this size yet.

Well, they look great. It was unfortunate when the company that was making the 510 adapters that those heat sinks were designed to work with just stop selling them and had no alternative means of sourcing them. I was thinking about getting withmy machine shop to see about them make a similar adapter for me. But at the time there was starting to be a lot of negative attention on mods. Reports of batteries, exploding in them and other things meant to drive regulation on that market. I just felt it wasn’t a good time to put a lot of effort in continuing the product line.

They were great though, and the selection of mods out there was and probably still is huge with lotta unique looking bodies. It was a good idea to make an easy approach instead of converting an old flashlight body or having a full unit machined for a Laser build. Might be worth going back and revisiting as I still have a lot of those heat sinks. I think I even still have a batch somewhere that had the integrated focus adapter as well kind of look like the old Ehgmus hosts.
