What did you mod today?

The yesterday finished VG10 triple Nichia Video:

Nice! I have a VG10 lying around for ages now, you remember me that I should do something nice with it :slight_smile:

Just finished putting together a dedomed Sst-40 with a TA bistro driver in a Convoy C8. Man, this thing is a little beast! 158kcd and really, really bright! And this is before fine tuning the focusā€¦

Decided to add a zoomie to my edc rotation. So I updated my i3 to fit in.
Dedomed xp-g2, blf a6 driver, eagletac gitd tailcap and a nice brown bake.

Put a recessed switch in the D4ā€™s big brother too

Today it was raining so i was busy :slight_smile:








There are 3 fixed voltages from PC power supply.
Adjustable is up to 32V 5A buck-boost (DPH3205) powered from the same PSU.

Binding posts and one 5.5Ɨ2.1mm connector on the rear are for powering DPH3205 from any DC 6-40V external power supply when I donā€™t have access to 250V AC.
Other 5.5Ɨ2.1mm connector is 12V out from PSU.

That looks a b.a. power supply, well done!

Thank you :slight_smile:

I made a duplicate of the Titanium plate they put in my neck. I have a PDF document from the maker of the plate that lists a couple of dimensions, this let me size it based on the X-Ray of the actual plate itself. Never milled anything before, especially not on a lathe! Some of this was hand work, I thought itā€™d be somewhat easier on commercially pure grade 2, it wasnā€™tā€¦

The very small slots I didnā€™t put in because my 2mm 4 flute bit wasnā€™t up to it. And I still should probably refine the ā€œ+ā€ pattern windows, but thatā€™s file work and Iā€™m done today! :stuck_out_tongue:

I did it for a pocketable conversation starter. :smiley: It weighs a mere 4 grams and isnā€™t as cut-out as the actual plate, so in reality the plate weighs even less than that. Itā€™s 2.1mm thick, 1.5mm in the center, 18.4mm wide and 38mm long. This is an Xtend plate from Global Medical, made to be able to add an extension into the middle groove and the small slots are locators for this extension. (My Dr. is probably figuring more work will need to be done above the existing plate, hence, the add on style Xtend plate)

Their pictureā€¦. yeah yeah yeah, CNC machines rule! :stuck_out_tongue:

I modded a 1$ Skywolfeye Zoomie to UV 365nm LED

Iā€™m Happy with the output :slight_smile:

Lol a 3.7V LED with 700mA and only 35-60mW luminous intensity?

Any aerious LED puts out 700-800mW at that power

Even a cheap Epileds is better and cheaper

I didnā€™t use a nichia UV led before but the output of this led to me looks good and illuminates things well
I think that the ā€œ80mwā€ was a typo in the description, Maybe ?
Of course I looked for a nichia led but couldnā€™t find one unfortunately

Thatā€™s so metal.

You are now officially Too Metal To Headbang.

I have 4 UV lights, each with a different emitter. 3 of them are Nichia. 1 is LED Engine LZ1. The top of the line Nichia was the most difficult to acquire. Itā€™s not as obvious the differences between these 4 as I would have thought, especially considering the price of the top of the line emitter, but it sure cureā€™s optical adhesive in a hurry!

Convoy S2 18350 NVSU233A (this one has a weird Silicone add on dome from Nichia, works, but looks funky as itā€™s really big)
Copper X6 with NVSU333A
Jaxman U1 with NCSU276A
Solarforce L2M (18350) with LEDEngine LZ1 (this one has an AHorton aspheric)

The Nichia NVSU233B is also great, even less visible light output and more UV output
Only downside is the higher Vf

Modded a Thrunite TN-31 with a SST-40, already had the light with bypassed resistor mod and on turbo it gives the XHP-35 Hi led on the AceBeam K70 a run for its money. Itā€™s blindingly bright!!!

Dangit TK, I was all prepped to rock out with some April Wine! (uh, 1979 head banger music?) [memoryā€¦ sudden ancient flash of Alesha in her ā€™78 Trans Am with Lightning Rod shifters, literally head banging in the car, driving, to April Wine. Scared me! She was a bad driver when she was watching the road! And along with that memory, another time she ā€¦. nmā€¦ suffice it to say the police were involved and it wasnā€™t music.]

158 kcd awesome , Hey Sledge, whats the tail amps, ?

Thanks!

I havenā€™t tested it on a full cell yet, but I got 8. something with a cell with unknown voltage. Iā€™ll check later today with a fully charged VTC6.

I built my first driver from scratch (well, from oshpark and a bag of parts) and it worked!

Even better, I got it to do 4-channel PWM for red, green, blue, and amber LEDs. With an e-switch to control it.

I had thought the 3rd PWM channel was weird, but no. The 4th channel is. The attiny85 doesnā€™t have direct support for 4-channel PWM (the hardware does channel 3 OR channel 4), so I had to do it semi-manually by chaining an extra interrupt off the PWM timer and using that interrupt to manually turn the 4th channel on and off.

Also, for some reason the 4th channel is inverted so 255 is off and 0 is full brightness. Iā€™ll have to see about fixing that.

But anyway, woot! This means that soon I can start on the fun parts.
