    i know how you feel, i used to live in buffalo NY and shopped in canada alot back when the exchange rate was around 50%

    Question: are there issues with VF and drive current between various leds? will a Q5 with a higher VF not benefit as much from this driver? it seems like alot of people are modding their lights with a Q5 only to find out the lights original driver cant deliver as much current as it use to due to the higher VF of the Q5. Do you recommend a specific bin? what about a seoul or rebel100? basically wondering which emitter would get the most current from this driver. thanks!

    Sorry, late to this thread.

    Where can I get ordering details, price etc...

    Also, can these be trimmed to 14 mm (0.55" sammie sized board)?

  10. #340

    Default Re: FS: Microprocessor controlled drivers

    Size: 16x6.5mm (L1P size); Diameter can be trimmed down to 14.5mm
    Most info is on first post.

    This is a LOOOONG Thread, in short will there ever be a 17mm li-ion board for sale?

    Thanks!

    Question (I don't know much ...)

    Is a driver for 3.7v lithium-ion also going to work with 3xAAA NiMH?

    Got a handful of $5 Chinese flashlights that use that setup, looking for a way to put a driver in them (lots of room, just a resistor behind the LED as built).

    Are there any 1AA nimh available? I see in the first thread that a beta driver is gone. Is that what it was?
    Also, I didn't see any paypal info there on that page. Can you post what you had and what is available? I tried to read all of the posts, but it got confusing. Sorry if I am missing something Thanks!

    Hi, I am the same, read the first post and the pricing info is missing at the moment. Does this mean that they are currently not available?

    Many Thanks

    Is there any chance that this is it? Someone mentioned that it seemed very similar.

    Yes they're identical, except for a different UI. The text says 17mm but the picture shows a 16mm one. Both sizes should be available if you ask DX I guess.

    Things don't always go as planned...

    RV7, I like your setup better with the simple low, med, high. Will you be offering any more of these?

    Did the manufacturer producing your circuits take the design and start selling them to DX?

    I actual prefer the extra modes (I like the slow beacon mode for one), and the strobe and SOS modes can be avoided if they're unwanted. More people on CPF seem to prefer the simple Hi/med/very low interface that your circuit provides though. I'm still hoping to see a similar circuit running on a LiIon.

    It has to be more than coincidence that the DX board is exactly the same (except for the UI). I hope nobody stole your design.

    Three-mode simplicity is certainly worth the difference in price to me, not to mention supporting a fellow CPFer. And I'll bet the DX board doesn't have hand-wound inductors!
