Are you amazed EVERY time you work on a light and it's successful?!

I guess they call that, low self-esteem.

Had an XPG2 on Noctigon and Qlite 3A driver laying around, then I saw that RMM was selling hosts too, so I got the Convoy S2 host to put them in. After just a bit of wrangling and soldering the 4th star to ground to get the moonlight mode I put it all together and popped a sweet LG D1 18650 in, charged to 4.35v, and VOILA…Let There Be Light…it WORKED!!

This makes for a throwier than normal tube light with a smooth reflector that I got from Simon. The S2 is beautiful, I don’t understand why it’s so much cheaper than the others, quality is amazing for an $8+ host!

ANYway, the point is…I’m absolutely AMAZED every time something goes well. Must be because the first attempts went so bad, but when I button it all up and hit the switch it’s like I took a pile of parts and MADE LIGHT out of them! Most people don’t get it but I’m betting a lot of you do!

The next attempt may be the classic “turning a C12 into an MTG2 wall of light” trick. RMM has everything necessary, all I gotta do is drill that reflector out. How hard could THAT be, right? Um….we’ll see. Beer

Yep, I'm with ya.  I'm amazed when things I work on actually work!  I always expect the worse due to past experience.  It's not just with flashlights, it's everything!

That must be the addicting part, succeeding where once there was failure.

It’s like gambling, if you NEVER won at it, you wouldn’t want to do it, but you hit one jackpot and you’ll be chasing that feeling through many losses.

Or something.

Too true. My success rate is about 30% on the first try, so I’m ecstatic whenever things work out perfectly. Smile

You learn to expect success when you’ve been through enough failures to learn. It’s the little things that trip ya up at first, then as you learn all the little details you begin to expect everything to work according to plan.

Getting there, but there are still surprises. Like hooking up a 3A driver to an XP-G2 on a Noctigon and getting a Hi of .73A. ? Expecting 400-500 lumens and getting 217. It works, but not at the level I was looking for. It’s all good cause in this case the light is tiny and 217 is probably more than it should be doing in the first place.

But it works! Yihaaaa! Smile lol

I think my biggest problem is rushing to get done.  Currently I'm not getting much free time to do things so when I do get some time (maybe 1/2hr to 1hr) I try to rush and get done.  If I don't get done I risk wondering where the heck I left off when I come back to it days later!

3 amps to an XPG2 is pretty freakin’ bright! Are you going to ‘settle’ for less?! I’m really happy with the whole thing, it feels like a lot more lumens, I guess because of the focused beam and the slightly cooler tint (3C) than the 5C1’s in my other Convoys.

I can really relate to this, Garry. I’ve forced myself to slow down and try to enjoy the process. If you don’t have the time, of course, that would be difficult.

I’m gonna have to settle in this case, it’s a mini C8 and it’s all JB Welded together! It’s got a nice beam, quite a bit of light from a 3” mini for sure. Was looking for twice that though. Might be partly the small cell required, but I’m thinking there’s some resistance pulling it down as well.

I have a full sized Convoy C8 with an XP-G2 R5 2B on a SinkPAD pulling 4.55A through a stacked Qlite and running from a Samsung 20R. It’s 883 lumens out the front at 30 seconds, fires up at 969 lumens out the gate. Smile

Edit: Good luck on the reflector, it’s much much harder than you might think! The key is in not damaging the very sensitive plating. Wink How are you going to hold it? How are you going to get the dust off the inside of the reflector? Can’t wipe it off. Washing it will almost certainly leave water spots. Almost any touch to the plated silver finish will leave scratches. A tip, mount the reflector backwards in the bezel, use the host to hold it and the emitter hole will be out in the open where you can get to it, plus you’ll be working from the non plated outside. Smile A rubber sanding arbor can be expanded inside the battery tube at the back end, then the arbor can be mounted in a drill to slowly spin the set-up. This will allow you to, hopefully, cut the hole a bit larger with a dremel tool without doing damage to the perfect mirror finish inside. If you clean it afterwards, a mild soap such as shampoo can be used, boil water to rid it of impurities or use bottled water and then blow dry it to stop spotting.

Thanks man, it DOES sound difficult! I was just going to run a drill bit in there and then blow off the dust. This lack of planning is what results in ‘less than successful’ projects. Thanks for the heads up! Wink

If you are going to use an actual drill bit to enlarge the reflector, be VERY careful, you might end up tearing the reflector instead of making a clean cut, especially if you don't have a drill press and a good way to hold the reflector. I ended up marking mine with a sharpy and then grinding it out with my dremel because I currently don't have access to a drill press or firm enough vise.  I wouldn't try to drill it out free hand.  My hole isn't perfectly round, but really it doesn't affect the beam pattern and the plating wasn't damaged.  

To rinse the reflector I blew off all I could then I rinsed it with some 97% isopropyl alcohol.  It isn't perfect but good enough.  Distilled water or fairly pure isopropyl alcohol shouldn't leave noticeable spots on the reflector (it is the minerals in the water that leave the spots).

Mountain Electronics : batteries, Noctigon, and much more! What's new?

I have not used it yet for this purpose, but I am sure this thing from my toolbox will do the job of, in dutch it is a 'gatenruimer', don't know the english word. it enlarges holes by scraping off the edge. it does not produce grit that dirtens the reflector, just clean scrapings, if you apply it from the front end from the reflector, the scrapings will probably just fall through the hole.

Tapered reamer - great tool to keep on hand!  Ordered mine from Sears online here in the US (ship to store), but it's also available at Harbor Freight (don't know the quality though).

Ok, Harbor Freight calls it a "T-handle reamer"

Always gratifying at least. I like trying new ideas and they rarely work the first time mainly due to my still weak soldering skills. The more effort I put into something, the more dissappointing the failure and the more gratifying the success. I still feel relief when I get the expected current from stacking chips.

Just finished another light. On assembly I have learnt to test at every stage. I hooked the driver up to the led, nothing. Test the led by itself nothing, hook another led up to the driver nothing and finally another driver onto the led and we have light. I have no luck at all with these electronic things. If I had not tested before ass anfd finished the light I would of lost far more hair than I did. Smile

Nice reamer, gotta find me one of those! Not sure from this side if it'd help me out or get me in worse trouble...

That bit about testing, it's true. At every stage keep a running idea of how it's working, then if something goes wrong it's easily solveable. Finish it and have something go wrong it can be a nightmare to find out what the issue is! That said, do I always do that? Nope! lol, and it get's nightmarish sometimes too!

There are those here that have the entire plan laid out, start to finish, finish to start, every possible detail written down and planned for. While I am getting better at anticipating the end or near end, I still find myself running into a wall on something I didn't foresee. So giving some thought to the whole process, planning it out in your mind even if you don't write it down on bar napkins (you know who you are!) will help to keep you from getting snagged on something when almost done. Whether it's stripping some anodizing on threads so your ground will be solid, drilling and tapping a small screw so, again, your ground will be solid, or preparing for a way to solder the ground ring to brass press fit into the pill so, you guessed it, your ground will be solid.

I've had some ground issues. Silly When going for high power, you have to make sure both ends are solid as a rock. You want the current to flow, you DO NOT want something to come loose and short out a 20A cell!!!!!

Funny. I know just how you feel I just finished my first build this weekend. I put a LD-29 and a XML2-T6 3B in a Ultrafire F10. It took forever..... and I had to 'Fix' the driver after I raged on the thingYell!

But it works quite well!

Hmm, I hate so say it and load the suspicion upon me of being awfully self-confident, but no: I am not always amazed if a mod actually works. I do think a lot about if what I do is feasable beforehand, that compensates for the little actual 'workbenchtime' I have for the hobby, with work and family going first. But it makes that I do not make a lot of  design errors. I do scr*w up a lot of the practical work though, but manage to fix most of that, that does amaze me sometimes.

I was TOTALLY amazed yesterday when my cheap old benchtop drill press actually turned an aluminum rod true! I was able to take a 1" bar down to 29/32" and cut a recessed end into it for the Qlite driver, all on the drill press! I clamped an old high speed steel planer blade into the drill press vise at an upward angle, used the down travel of the drill press to be the "lathe". Hey, it worked! Smile

The black in the aluminum is from a black sharpie to show me where to part it off for the Noctigon. Wink That's an 18mm McGizmo reflector on top of the XP-G2.

hahaha, yeah, well, never use it...was checking length to see if it might be shorter than the Efest IMR10440 for the miniC8. I got that years ago when I got the LD01.

Yep I'm still amazed if the light turns on when I'm done. In fact if it does the first time then I wonder what I did wrong.

 

This is what I use for enlarging the hole on reflectors. It also comes in handy for filing down drivers to size.

 

 

 

 

I’m a junky, I mod lights so I can sell lights so I can buy more light to mod so I can sell lights to buy more lights to mod.

About a week ago I worked on two lights at the same time, neither worked when finished.
Last night I revisited them and one had the + wire to the emitter loose , must of been when “twisting” the wire putting in the driver, simple fix Smile
The other one has heat damaged trace on the pad, replaced led, easy fix and a bit of fodder for my first reflow when the “sinkpads” arrive.
Then I took my favourite light for a walk, Small SunzyT08, feeling good about fixing two lights and noticed that the light was brighter and getting warmer than usual, even allowing for the 25c air temp, so I switched to med, or tried to, I now have a one mode, 4A light, so a light I worked on a while ago (shorted out the sense resistors) gave out, ah well, I intended turning it from a 2p to a 2s anyway, Driver ordered.
Win some loose some, this is a hobby for me so working on a light two or three times gives me more hobby for my money 8)

Cheers David

Nothing to see here folks, move along...
