Nice!

Whoa…The price is steep! Anyways, I’m not a connoisseur when it comes to drivers but the mods seem nice!

Look guys, I’m not a chinese factory assembling in thousands. What You pay here is not only hardware but also days/weeks of code development, someones creativity, hours of testing, making patches etc. Please keep this in mind :slight_smile:

Bocian please do not take it badly! It was just my opinion. I know you have done a fantastic job. I do not know how to use drivers, solder them to leds etc. I am sure I would have got one else (even if the price is steep). I find the functions it does awesome!

We are on Budget Light Forum and price is always important for us.
I know the price of unmoded 3.04A Nangj 105C with custom firmware from DrJones and it’s half your price… So yes there is not your hardware mod but DrJones custom firmware are great too. He can fit a great firmware on ATtiny13a.

Like I said before. I have also another, cheaper version of programmable driver based on original Attiny13A. Same 4 programmable modes (11 modes palette), 3-click strobo, two way modes navigation, 8-click reset to factory settings only without thermal monitoring and voltage measurement (comparing to Attiny25V mod). Answering to DrJones question: Using Attiny13A (with 16-18kHz PWM to achieve lack of flickering) there is not guaranteed that the lowest mode: 0,02% will be visible. It depends on hardware variations (to be precise: “parasitic” capitances of AMC7135 regulators, the more AMCs on board the bigger, summed capitance). Attiny25 (I think because of the internal construction differences) is much more resistant to this phenomenon (lowest modes are always visible). BTW DrJones when developing new, custom PCB for a driver You should think about dividing 7135 regulators connection to PWM channels. From a single piece of 7135 it is much easier to get loooowest modes :slight_smile: Descibed above, “budget” version, based on Attiny13A I can sell for 9$ plus shipping cost. :slight_smile:

Does the Attiny13A version have the low-voltage warning?

Yes, it does. Same as Tiny25.

I really do appreciate the great work that went into these drivers, but...

if you need your flashlight daily, for work, I can understand that a user interface improvement can be invaluable. But for me, a humble hobbyist, a flashlight driver at more twice the cost of the same driver with a ok, but just not perfect UI, is not worth it I'm afraid.

I can see some paradox here. You are seems to be such sparing people (talking: sorry but not worth of it etc) and You spend for example ~30$ to get pill made of copper for a flashlight that is worth 20$ overall :slight_smile: Guys, OK that is really not a tragedy for me if You will not buy it. This driver was created for me, to use it in flashlights I produce :slight_smile: Wanted just to share with You what we are making in our polish flashlight world 8)

PS. It really seems to be like: One lamb says: Yes it is a great deal! We want! And the others also. Just like it seems to be…

I agree, I am totally irrational in what different flashlight parts should cost....

Thanks for offering these Bocian. I wish other members here would offer their drivers like you have, but so far I think only Dr Jones has made his available. Would you also sell these with stacked 7135's? With the added cost of your driver, and my poor skills, I'd hate to screw it up. You seem to have much better soldering skills. A spring wire mod would be great too. I'll order one when I get back from my next trip.

I second that.

Hardware alone costs some, plus work to make them even when one already spent tons of time coding the firmware. Shipping costs a bit in Europe too.

@Bocian: Due to the language barrier, (which is my fault, not yours) I think I only understood about 50% of what the driver actually accomplishes, so it was hard for me to decide if one would be helpful for what I do or not. I do empathize with your observations about the copper pill however, and think that your offer is very reasonable. Thanks for bringing it forward as an alernative to consider.

No problem. I can assemble with additional AMCs (0,5$/piece).

Looks like a great driver! Price looks fair too. :)

PM sent!

I’d be delighted to see you put a review of a stock light and after the mod with some pics and runtimes etc :slight_smile: Would be awesome!

From fully charged cell to 3V, I assume it will work pretty much like a Qlite/nanjg105C. Runtime ( especially on high) will depend mostly on output, battery, and the emitter type (Vf). I wont bother with runtime graphs and such. I guess others have already posted some runtime graphs with various setups using fairly similar drivers.

I might do a stock vs modded light just for fun. But that will only display the difference between a mediocre 2amp light, and a light with lots of amps. Nothing that hasn't been covered before in a ton of mod threads.

Its the UI and special features im interested in. I will test all of them. I can report back how well I like it. Ill probably do a simple runtime test from 3V and down. I look forward to test the overheating function as well. :)

If its as good as I hope, this will pretty much suit all my needs for a "sophisticated hotrod" light. 0:)

Now available with increased PWM speed and better thermal mechanism.
