FS: Extended version of Nanjg 105C driver based on Attiny25V

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.

Did you discontinue the weekend promotion already? It's still the weekend.

In few days I will provide new version, with auto temperature calibration procedure.

Thanks, I thought my calendar was running slow again.

PM and payment sent. Thanks.

I would like to inform that since 1st February Polish Post Company changed its pricing :frowning: Now shipping World Wide (registered, priority mail) is 5,5$.

C’mon, How much is that? Two saturday evening beers? :slight_smile: Good Job Bocian ! I’ll definetly have one for testing :slight_smile:

Final versions of Attiny25V and Attiny13A driver have been established and little price update :slight_smile:

I hope you don’t mind beginner questions, but the programmable modes you have make me interested in this driver.

Both Attiny25V and 13A are 17mm drivers?
Are they for 1 x 18650 applications only, or for 2 x 18650 also?
I don’t really understand the difference between 25V and 13A versions. I thought I read that 13A also has temperature control? The 25V costs a little more, could you specify difference for beginner?

Thanks in advance.
