What did you mod today?

Geuzzz · July 14, 2019, 5:12pm

My work light died today. So I Frankensteined something together for the time being. Aspheric quad 219b doesn’t look to bad.

Beam shots?

djozz:

I got fooled by a travel clock today.

Bought it new at a local store (Hema) last week.

(Sofirn C01 is for size reference)

It runs on a single AA and has a small 3mm led that lights via a momentary switch on the back, to check the time at night.

It is pretty bright, my planned mod was to add a high value resistor in series with the led and replace the momentary switch with a slide-switch, so the clock can be lighted all night at a non-disturbing brightness. I like that much better.

I was surprised to like the tint of the led, pretty good for a cheap travel clock, so before starting the mod I checked the tint with the spectrometer.
And good it was indeed: 2300K, 96.3CRI, R9=83, duv –0.022. This is a holy grail led , where did the Hema source it?

Then I checked the spectrum :person_facepalming:

I haven’t been around to know it, so I ask: this is an incan, right?

I’m very interested in seeing the result as well.

Yes,mit was an oldschool mini-incan bulb. Probably cheaper than a piece of circuitry to boost the voltage of the AA-battery for use with a led.

I fixed my old bluetooth speaker…the stupid microUSB charge port broke off the mother board….so I opened it…soldered in a tp4056 module, cut end off bad USB cable and wired in…closed it up…yay…can charge the battery and listen to my audiobooks on my drive to work

That’s the only thing I have modded lately…

I guess this counts as a mod

I’m at the proof of concept stage, testing layout.

I’m building a:

Replica prop from Pulp Fiction
Bonfire/Fireplace emulator
Suitcase with ~18000mAh capacity + 5V USB output
Very big over-engineered ambient temperature measurement device
Orange quad mule with unnecessary active cooling, just because!

It’s gonna have 9 x 18650 LG S3 2000mAh cells loaded when it’s done.
It has a 3A charge circuit, the 1A micro-usb took forever charging this many cells at once.
I’m still considering adding a second emitter choice, so it can shift from orange to perhaps a warm white.
It’s running on a Emisar D4 driver, flashed with the latest Anduril 2019-06-02 firmware. So it has all the blinkies.
The 4 leds are salvaged from a Orange Beacon light. All I can find is that they are “3W”. Have 4x XP-E2 P3 amber LEDs on order, for MOAR OUTPUT!
Still need to find something to cover the leds, to act as a diffuser. Something that can fold, or fit in the case when closed.

djozz · July 19, 2019, 8:56am

Looks impressive. Mind not to go through customs with that suitcase.

i42dk · July 19, 2019, 11:22am

Haha, imagine that

Anyone know if it possible to buy a luxeon V 4040 gasket anywhere?

g_damian · July 22, 2019, 12:47pm

Tool AA with E21A 5000K kit from virence.com:

No gasket has been used:

There is one noticeable ring in the beam:

g_damian · July 22, 2019, 12:51pm

Tried M21A (stock 6A driver) with dedomed SST-40 from kaidomain. I didn’t like the result, so after beam shots I put 4040 white flat instead (and it is awesome now)

Beam shot (GT mini WW, M21A dedomed SST-40, C8 white flat):

g_damian · July 22, 2019, 12:57pm

One more build post for now.

It’s C8+ and SST-20 4000K from kaidomain (fb4?). Throws almost as good as GT mini with low CRI emitter.

Led4power driver with thermal enhancement kit for Convoy S2+:

Beam shot - GT mini WW (measured lux: 38), 4040 white flat M21A (lux: 100), C8+ SST-20 (lux: 33%)

MascaratumB · July 22, 2019, 2:09pm

Moded a deodorant cover to make a GITD diffuser for my Wuben T70.
I applied some Montana GITD spray and a piece of GITD tape in the interior for a better fit on the bezel!

TrueRMS · July 22, 2019, 3:54pm

Changed the outter ring of purple peds to orange on this E07.

jon_slider · July 24, 2019, 3:34am

I fixed my sw45 triple RRT-01!

before:

replacement driver from Jetbeam

my first mod ever

woohoo!

and now I own all sorts of modding tools and supplies…
I feel like dancing!

major thanks to pinkpanda, CRX and Clemence for the inspiration,
and to moderator007, SKV89 and pol77
for all the support and encouragement to learn to roll my own…

gchart · July 24, 2019, 2:28am

First mod? That is worth dancing about! Great job JS. Something tells me this may just be a beginning… (modding is addicting!)

Today I modded my PulseLabz Guardian Series Signature Gaming chair.

I'm not a gamer and I'm not a small person. Actually it was more of a repair than a mod. The gas piston failed after the first week. Two weeks later I had a new piston in hand. The kind people at Pulselabz also provided some written instructions.

"The first step is to separate the piston from the tilt-lock mechanism above. To do this, first raise the chair to the highest position you can with the height adjustment. Then find a friend to help you, both with one leg pushing down on the metal base and the other leg on the ground, wiggle the chair upwards and downwards in a rhythm, with one arm holding the height adjustment lever in the open position and the other arm holding the backrest until the piston separates from the top.

The second step is to separate the piston from the metal base. As your old piston can go in the trash, the method we came with will damage it but its okay. What you can do is take off all the casters/wheels, and then find a concrete parking spot block, then holding the metal base, hit the piston really hard against the concrete parking block and it should pop out upwards

Let me know if there's anything I can help with."

I chose another route:

Worked great.

Too many mod threads so now i’m re-posting to my favorite one, sad day:

Got one of my dark blue 0.3mA aux boards installed today. Compiled a hex file with aux support and the latest Anduril features like manual memory, two level lockout brightness, soft reset, etc. The version with MCU support isn’t the most simple option but I did want the ability to turn it off.

It’s sliced LH351D 5K 90CRI LEDs also.

g_damian · July 25, 2019, 7:00am

Dark blue board looks great Do you have maybe beam shot comparing sliced LH351D 5K with other 5000K led?

g_damian · July 25, 2019, 10:54am

This one is the longest build with many failures so far.

Long time ago I ordered S2+ CU. The plan was kiriba-ru triple with Luxeon MZ 5700K. I wanted patina, so coating was removed, not ideally, but it’s not bad. The light was nice, but kinda green and extremely floody. So it went to rebuild box.

New idea was 4*E21A 4000K & 5000K mix and kiriba-ru pill. Wiring those little boards is quite challenging. Tried four times and finally destroyed MCPCB. Thankfully I had one spare. So I reflowed those little yellow guys to their new home.

I wanted to use 60 degree optic. Some time ago in another build I glued the plastic holder (which came with the optic) to the MCPCB. This time I couldn’t do it. Does not matter how hard I tried, the glue was all over leds. I cleaned the board and decided to use gasket for XM size leds.

Next day, finally:
