Danke schon:)

Every now and then a non flashlight related post finds it’s way into this thread… Here is another.

I got a Mavic 2 pro as my first drone last year but it’s a bit of a hassle getting out to fly it as I live in an apartment. It’s also a little too expensive to learn how to fly a drone with, already crashed it once into a tree, so I tried simulator software but my old laptop couldn’t handle the graphics. Instead of upgrading the laptop I went and got myself one of those real cheapo mini drones just to learn how to control a drone from my couch. Man have I crashed it! Durable little sucker, props and prop guards flying everywhere, just stick ‘em back on and it’s ready for more abuse. However, running around after it in my apartment is annoying. I have goggles for my Mavic 2 so I want to fly with goggles indoor too. What to do? I want to stick a little camera on it but these little suckers fly really bad when weight is added, I already tried a larger battery.

It weights in at at 52.5 grams with the battery.

I bought a cheap little camera, I also bought some compatible cheapo goggles that has detachable screen.

So I had to shed about 4 grams of this thing… I hacked it up pretty good, removing useless joke camera and wifi transmitter it came with, a LED and a whole bunch of the plastic frame:

I soldered on cables with connections to the battery poles on the main board and taped down the camera and tx board. Antenna is sticking out in the front, might move it later as it’s in frame but it’ll do for now. And whatta ya know, it ended up 0.3 of a gram lighter:

So it’s ready to go and get all bashed up again! I just hope the camera holds up, I don’t care much about the drone itself, it’s has long since passed what I expected of it and I have a few more lined up to take it’s place. The camera I can move to the next drone in line when this one has had enough. I did get a spare camera too, just in case.

Test flight tomorrow, can’t do it now as my girlfriend as asleep.

Sounds like you are having fun! Nice hack.

Nice MT-g2 build 1stein! did you open the reflector up at all to fit the big led, or it just worked out how you wanted it to?

Thank you! Yes, I’ve enlarged the emiter hole in the reflector to fit the LED. Furthermore I’ve put the special gasket to make the ref rest on it instead of the led, so the MT-G2 edges are secured. Everything took like one hour so it wasn’t very hard to achieve.

And the tint is completely different now, as measured in the hotspot.

On lowest mode:
CCT=3530
Duv=-0.040
CRI=96.8
R9=89

On highest mode:
CCT=3700
Duv=-0.0059
CRI=96.0
R9=93

So great CRI, 3 percent points better than before slicing, and wonderfully rosy.

The output at max is now 560 lumen (with slightly depleted battery), of which most is in that hotspot.

Non-slip pads did not work for me, that is why I went for the custom tool, and indeed it needed an amount of force that I could never have applied with the pads.

[I’d been wondering if anyone had come up with an “upgrade kit” for lesser drones. Looks like you’ve got the essentials of just that. Must be quite an asset in helping you to learn better drone navigation skills.

I made another… same weight as the the other before cutting it up:

I cut this this one up even more and managed to lower overall weight with 1.2 grams.

Nothing ground breaking but something new to entertain me ...

It's been a while that I've done some emitter/driver swaps. This is a triple host swap. The main

reason for this is to get rid of the XH-P 50 doughnut hole beam in the L2, and the 6V Zener FET driver had to go

with it. I've also found that with 2x 26650s, this older LED is overdriven by the MTN 17mm. The solution is to use the

Guppydrv Rev. 2 group 12, at no more than 70% or lesser batteries. There are Carclo single emitter TIRs to fix the

doughnut and I have a number of S21As. I used a clear TIR, at first, but the beam is better with a 'sanded' TIR.

I want an SFT40 but until I order one, the next best thing I have in inventory is an SST40 for the L2. My MTN 20mm

Crescendo driver makes for a simple yet interesting thrower interface. Who wants anything but 100% in a thrower anyway?

The Utilitech 3C has a great reflector with very good throw, similar to the L2 and the XP-L HI won't be

too hot for the plastic reflector.

After the swaps:

This has been a great throwy host that just about handles it all. I've had it in the vehicle with Li AA primaries, and can be setup

for a 21700 or an 18650.

SFT40 in an EC01.. not a success :/

First the small screw preventing the mcpcb from rotating was in the way. Not a major issue though.

But I forgot to take the OP reflector into account, stupid… I don’t even know what to call this, except the word iris comes to mind.

Next up: try again, but then reflow the emitter to an Astrolux FT03 that I have lying around. But that’s for another day!

I tinkered a bit with Convoy’s 12V 2,5A GT-FC40 driver. I changed it to 6V output and adjusted boost converters input limit to higher value. It was limited to 10A, but MP3431 boost converter should handle higher. I also changed bigger 1R5 valued inductor to it from broken Convoy driver. With 6,7 mOhm current sense resistor mine gives an output of 6,2A and draws 12A from battery. This with battery voltage of 4,1.

Nice driver modding Haukkeli

Nice mod..Please,which driver was used? And-is it for two 18350 or one 18650?

One 21700 and boost driver from Simon.

This one

I haven’t done anything with my flashlights anymore for several months, but today I added aux leds to my edc FWAA. Due to the fact that attiny85 sits inside, there is only one color – ice blue, but I think that’s enough for me.

FWAA aux mod

I also finished a mod for a friend recently. He saw it at Vinh’s and wanted it too. 7x xhp50.2 5000k mule.
Apart from the auxes, I also added a blue GITD tape to the inner wall. I think it was a good idea.

That is really neat…outstanding! Putting that on my list of I-should-probably-dos.

there are some inexpensive Novatacs on ebay atm.. if you need more.. LOL

I just modded one to 519a 4500k, and did the 250 click unlock, to make it programmable..
.

really pleased with the beam quality, and output increased to 270 lumens..

250!? And some people complained about 20 clicks instead of 10 in Simon’s drivers.

Just for fun to see what would happen and get some practical experience with flashlight modding; Convoy L2 with B35AM. Maybe a high CRI thrower.

I’m considering this a work in progress. Some practical limitations, such as no OP reflector available and unfortunately no 2 cell 6V driver (used the 20mm Convoy B35AM driver). The dedicated B35AM gasket is just too small for the reflector hole, so had to use a unknown gasket that was much thicker, but fits (possibly XP). Also the stock L2 tail button is not suitable for controlling it. Need to find a replacement for that. But I’m was pleasantly surprised by the beamshot. Was expecting something floodier, but it actually shoots out pretty straight. It throws further than the DM11 with B35AM. But up close there are rings that I would like to get rid off, just don’t know the cause.

Looks like the lens AR coatings creating those rings

@Verodin, I believe those rings could be reduced by a flatter, more shallow gasket. The emmitter just needs to be level with the base reflecting surface of the reflector. It really isn't that bad and the beam is nice. The color comes from the lens anti-reflective coating.

Today, had to run to TSC for something else and they still have these. I'm glad I had it for parts but I wouldn't pay $12.99 for an optic.

Aaand amber for the second FWAA. Here ice blue on low and amber on high. I used 1k for both.

Does stock FWAA FW support Aux or or did you have to reflash?
