I lost all my eagle stuff when I moved to linux

Can someone create and upload a 17mm to 20mm adapter board for the BLF 17mm driver for the new type C8 lights

Didn’t we used to have some copper adapters floating around here? I am actually in need of some of these myself. They were washers for something but can’t find them anymore.

New like the convoy c8? It works with 17mm drivers, I have a blf driver on mine without an adapter,

I found some that should work as adapters.

You can also get dedicated 17mm to 20mm driver adapter rings. I used to get mine from 3Tronics (now closed) but Googling “17mm 20mm adapter ring” produces several hits like this one from Kaidomain:

(TinyURL because the Kaidomain link broke)

There are other sizes at the bottom of the page, too.

Right…we used to have some at OSHPark that would allow fitting a 17mm driver inside a 20mm ring…or I believe we did

A fellow BLF member I talk to got a new light in and I was asking for him

The problem with oshpark is that it would have very bad thermal properties and could cause the driver to overheat depending on the driver used.

Hi Gang,

I would like to have some 17mm blanks made. One with a battery positive center larger enough to fit hanks gold spring (about 11mm), but on the back side a way that I can solder a negative contact without putting wire in the way of the rim. Can someone here assist me with that?

Hey. is there any project of the nanjg 105D driver somewhere available ??

Hello and welcome in BLF!

What do you want to make with it? What do you need?
If you want a 105D, you have to buy a 105D or 105C
Here in BLF are some similar drivers with similar Layout to the 105D which has more output channels, e.g. for some AMC7135 chips for regulated current and for a FET for unregulated maximum output.
Look at this topics for examle:

I would like to make a few flashlights for myself and my family, based just on nanjg 105D. That’s why I’m looking for a 105D tile design without FET. based on 6-8 AMC

Look e.g. here:
http://kaidomain.com/Flashlight-DIY-and-Tools/Circuit-Board-Driver-Board?sort=p.price&order=ASC&limit=100
Convoy-Shop on Aliexpress: driver - Shop Cheap driver from China driver Suppliers at Convoy flashlight Store on Aliexpress.com

They have very similar drivers. Some are an upgrade to the 105D. The 105C is the same as the 105D but with aditional stars for some options.

A good driver is e.g. this: https://www.aliexpress.com/store/product/7135x3-7135x4-7135x6-7135x8-with-new-firmware/330416_32734523412.html?spm=2114.12010612.8148356.8.5bb73cf1I0IKuV

Is this something okay under 105D?
https://oshpark.com/shared_projects/JEp3Wx4B

Yes. But remember that this driver is adapted to support 2 channels. If you use np biscotti firmware, in 100% mode you will have 7amc active instead of 8.

One of these will work like nanjg 105D ??

  1. OSH Park ~
  2. https://oshpark.com/shared_projects/d7oYStVQ
  3. OSH Park ~

The first is the same as what you mentioned earlier.
The second one is adapted to 2S power.
The third one maybe it is nanjg, but it looks terrible to me. I would be afraid to use it.

If you wait until tomorrow I will give you nanjg 105c/d.
But without stencil.

Edit.
HarleyQuin has already make a good PCB. It’s 17.6mm so you’ll probably have to regrind. It looks very good to me. But do not solderd all AMC. 2 pads must be left empty. Just like a pad under OTC.

Thank you very much,
I’ll wait until tomorrow

This is a great driver, all I use anymore for 17mm 7135 drivers!
I run BLF A6 and bistro FW but it would be just fine on biscotti, if loosing that last 350mA concerns you just bridge MCU pins 5 and 6 (after programming).

:person_facepalming: Why didn’t I think about it…
