Sold/Expired FS: Microprocessor controlled drivers

Re: FS: Microprocessor controlled drivers **1AA boards available now**

Holy sh*t !!!

Modded my L1T (SSC P4 USWOH) with my second driver board today, used a charged Eneloop and was astonished . This mod is clearly brighter than my L1D CE Q5 ...

Then I measured the battery currents (DMM replacing tailcap, resistance of DMM plus leads ~0.06 ohm) and couldn´t believe the numbers I saw. I checked them with a second DMM, but this proved the first one: Peak amps with a fresh Eneloop were 4.5 amps, a used Eneloop made still 3.5 amps ... wondering how high the emitter currents are with these input numbers ...

Please let us know, if you find some...

Maybe DIY one with a couple links from someone's necklace? :devil: I heard a crazy guy making a positive contact on the back of his driver PCB this way to be able to use protected batteries...

The LED current should be close to 1.1A and the efficiency around 75%. From time to time I come across an energetic driver with higher than normal output.

RV7,
do you think you could possibly adapt the design to 3 Volt, for one CR123/2AA? There's a need for good 3 Volt drivers for all the single CR123 lights out there with crummy stock drivers in them. The same applies to some 2AA lights.

Hi Stefan,

This driver is not a conventional booster. It works like a highly efficient transformer. It's the battery's capability that's limiting its output. However, with two AAs and one LED, the load on the batteries will be so light that it'd be easy to over-drive or even fry the LED if its Vf is lower than the design target. In short, it works well with 1AA, but is hard to control with 2AA without sacrificing efficiency.

With two AAs, it's relatively easier to design boost circuits the converntional way and still achieve both high output and high efficiency. There're plenty of ICs to choose from. I prefer to leave this job to those "professional" driver providers.

Re: FS: Microprocessor controlled drivers **1AA boards available now**

I modded an Elly with this circuit and a Q2 yesterday, and it kicks some serious *ss!
Really extreme output for an AA!! Nice work RV7!!!

I'm in for TWO of the 1.2v boards. your first post shows that there are none avail, is this correct?

Hi RV7,

What is the efficiency at 20% and at 4%?

Re: FS: Microprocessor controlled drivers **1AA boards available now**

Today 1USD = 1.0011CAD. Probably it's time to do a little more shopping in the US - I live just 10 miles from the border after all.

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!

Re: FS: Microprocessor controlled drivers **1AA boards available now**

and for 1xA (without strobe) and 1xB (with strobe)
thank you RV7

 

[Scattergun]

Are these still available and where are the prices/shippingfees??
I would like to order two Nimh without strobe!:wave:

 

[Scattergun]

Wohooo!! Paypal sent for three drivers without strobe!!:twothumbs

Re: Microprocessor controlled drivers

The new NiMH drivers are available now! Please check the OP for details.

What is OP? How much does the new NIMH driver cost?

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)?

 

[X_Marine]

Size: 16x6.5mm (L1P size); Diameter can be trimmed down to 14.5mm

Most info is on first post.
