    Default Okluma TinyDC

    Hey everyone,

    This is my first light to post up for sale on CPF, so I'll introduce myself. I'm a self-employed machinist and my work reflects that. During the day mostly I make motorcycle and oil-field parts, my specialty are the smaller and one off jobs. About 10 months ago I saw one of Mac's Tri-EDC lights and I fell in love (more on that later). Shortly after that, I ordered some parts, did a lot of reading, and started making various kinds of lights for my personal use around the shop. A few friends asked about buying them, and well here I am.

    Clearly this light looks a lot like the Tri-EDC. Like many of you, I just really wanted one. I religiously watched the WTS threads waiting for one to show up. After it became apparent that that wasn't going to happen any time soon, I sent Chris a couple emails. I thought that maybe in exchange for his plans, I could work on his backlog. He'd pay for material, I'd donate my labor, we'd all get Tri-EDCs and everyone would be happy. Like many of you, I never got a response. That's when I started designing this light. Visually I wanted them to be very similar, but absolutely no confusion between who's light is who's. For the most part all the components are compatible with the exception of the tailcap. My light has the tailcap boot retained by an oring, and does not use a threaded retaining ring.

    I take a lot of pride in my work and reputation, so if you buy one and you're not happy just send it back. If it breaks or stops working for any reason at any time, just send it back and I will fix it for free. I absolutely will not take anyone's money unless all the parts are made and I can ship a light within a few days. When I no longer have any lights available I will update the thread accordingly.

    The first 3 of these I sell on CPF will come with green tritium vials installed in the Carclo optic for free.

    To be notified about availability, you're welcome to join my mailing list. It's only for announcements about availability or upcoming work, and I promise it will be very low-traffic. I will still update this thread, but the email will go out first. Here is the mailchimp link: http://eepurl.com/bu0JAT

    Price: 250.00 plus 10.00 for shipping
    Available: No.
    Includes free trits: No (0 remaining)
    Paypal: jasapp [at] gmail [dot] com

    7075 Aircraft grade Aluminum
    XP-G2 R5, S3 or Nichia 219 (your choice, no extra cost)
    Carclo 10507 default, (10508, 10509,10510,10511 also available, no extra cost)
    Modes: ML / L / M / H (with on-time memory)
    Approximate Mode Currents: 2mA / 30mA / 180mA / 1300mA
    Driver also provides constant current control, low voltage warning, and reverse polarity protection
    McClicky Switch
    Acrylite Lens FF P-99 or mineral glass (your choice)
    Uses a 18350 IMR cell (not included)

    Titanium Pocket Clip (+25)
    Sapphire Lens (+35)
    Copper Pill (+25)

    If you want custom programming on the driver, that is *free*. If you'd like to change it again in the future, it's only the cost of shipping. If you want to send it in every other week to try something new out, that's fine. If you're not the original owner, it's still just the cost of shipping. If it's been awhile, I'll replace the orings and gasket at no extra cost either. Right now, I can not measure lumens only current. Hopefully I'll be able to measure lumens soon...

    Now, onto the pictures.

    Also. Can I choose the optic? I have some programmable 17mm circuits I want to use. I assume I can mod it? What is the pill made of? Id be happy to purchase one and review it. I sold all mine but have lots of Comparable I used to own (mac tri Edc, McGizmo haiku, sinner ti tri Edc etc).

    I'm pretty happy with it.

    Sure. I cut them out on a waterjet, tumble them in ceramic media and then hit them with scotchbrite. The hole pattern is the same as Mac's and McGizmo's, so their clips will work on my light. If you want the threaded holes but no clip, that's free just ask. They're 4-40, and I can toss in some stainless torx screws that fit if you like.

    I've made a couple in Ti, but I'm still working on the fit and finish. I think I'll offer them for sale, but I'm not 100% for sure. If I do, it'll be at least a couple months.

    No issues shipping to Canada.

    You're welcome to choose the optic. I only have the 10507 in stock, but I can certainly order the other ones. Or we can do whatever you want really.

    I assume I can mod it?
    Yes please. I'll help in anyway I can too. Drawings, specs, trying different ideas, you name it. I'm totally a hacker at heart.

    What is the pill made of?
    Right now the pills are done in 7075 as well. I have some copper and I'd be willing to offer a Cu pill upgrade for $25 if there is interest.

    Can you tell us the mode sequence and outputs? Would you be able to take some beamshots with the Nichia 219?

    The mode sequence is ML-L-M-H. I don't have any way to measure the outputs, so I can't tell you that exactly.

    I've never taken beamshots before, but I certainly can as soon as it gets dark.

    If you can post the current draws, some of these smart fellers can figure out some rough emitter lumen outputs.

    Beamshots would be great, thanks!

    I'll see what I can do with the current draws. I think I should be able to figure that out. Beamshots will be up later this evening.

    This is looking good, if you could do other materials like titanium/brass/copper you're definitely on to a winner here

    Is it this driver, with modes of ...

    Group of modes:
    1st* Star* : 2% - 25% - 100% (Default)
    2nd Star : 5% - 30% - 100% - Strobe - Beacon
    3rd* Star : 15% - 100%
    4th Star : *5mA - 2% - 25% - 100%

    ... 100% = 3040 mA, memory and constant current control, low voltage and reverse polarity protection ?

    Yes, that's correct. It's left in the default mode.

    I've made two out of titanium. They take more than twice as long to make, and it's really hard on my tooling. I may offer them for sale, but I'm not 100% for sure yet. I need to sell a few aluminum lights first, mostly so I can buy a big, carbide drill with through coolant. And I've done my best with the beam shots. Photography isn't my strong suit. Nichia 219, white balance set to daylight, 60 second exposure (maybe this was too long?). Moonlight, low, medium and high modes respectively.

    Just very rough emitter lumen numbers, for XP-G2 (typical bins), at 1 Amp each (x3) ... maybe 750-900 ? Accounting for reductions to get to OTF lumens, maybe 500-600 lm ?

    Sounds like a similar setup to what Mac was using. Does anyone know if it was the same board? I cannot remember anymore.

    Beamshots look good. Nice big floody hotspot, just like I like it. Yay optics! Haha

    They are all boards based off of amc7135 regulators, so very similar. I think Mac used the variant that maxed out at 2.8A.

    Default Okluma TinyDC

    Note that they both use 8 chips but Mac used older ones with less output.

    I believe the controller chip is the ATtiny13 (brain chip). The 8x 7135 chips are linear regulators and control the max current (more chips = more current ).

    You can get lots of funky programming in that ATtiny13 if you know how.

    Don't say you'll do a copper version. I'm on a copper kick but shouldn't buy anything until I know whether or not we (The CWA) will have a new contract, be working under the old one, or be on strike. Sadly I'll have to put my flashlight purchase in the hands of the negotiating team with that phone company that starts with a V

    Alright, this light now comes with 4 modes with memory. ML / L / M / H. The current estimates on those modes are 50mA, 166mA, 475mA, and 2200mA respectively. I can update the firmware on the chip, so if you'd like to do something different just let know when you order the light. Within reason, most customization to the firmware will be free. I'll take new beamshots later tonight since I've added a new mode and dropped the output on high a bit.

    Moonlight needs to be a lot lower. Think 10mA. Maybe less. Or just call it low.

    Ok. I want moonlight, and it sounds like everyone else does too. Dropping it down should not be an issue. I'll see what I can do, and update the original post accordingly.

    Something like .2 lm, to me, is a nice moonlight, IMO. But I'm not super fussy. Then maybe 10, 75, 300. Just rough estimates. That's about where my Tri EDC is and it's nice.

    Btw, is Okluma TinyDC the official name? Any significance to TinyDC? My brain is cooked this week so if it's obvious, forgive me.
