New 105D. replacing Nanjg-105c @ FT? (no stars!)

Thatā€™s a good point Fritz.

For my own part Iā€™m actually not interested in paying a higher price just for the stars, but other people might be. As far as Iā€™m concerned the OTC can be placed on top of the driver and the most recent version of my A17PZL Nanjg-replacement driver has a place for sending your <1mm switch+ wire through.

You can always stick the cap directly on the MCU pin, but it is a pain compared to having its own pad. I did this last summer with a bunch of AK47a drivers that I needed to be 100% single sided, and did it with the first revisions of the BLF17DD driver, but it really stinks to get it in place and is even worse if you have to reflash the MCU.

I agree RMM - when I saw others do that it looked easy, but when I went to do it myself I found that it was a real pain. I guess a person determined to do it that way could use a little radial-lead cap to make the job much easier? http://www.ebay.com/itm/3-x-1uF-35V-Radial-Capacitor-Tantalum-Free-Shipping-/260824509287?pt=LH_DefaultDomain_0&hash=item3cba5a2b67

If there is room I agree that a leaded capacitor would probably be easier. I actually bought some leaded components a while ago because in some custom configurations they are easier to use and more reliable than SMD components air wired together or soldered in crazy positions on the board.

Tantalum caps are tiny party grenades. :party:

By which you mean they work great in low voltage scenarios like this? :face_with_monocle:

Seriously though, what exactly are you implying?

Well, those should be fine here. Just triple check polarity and de-rate the marked voltage 33%. They are notorious for exploding and flaming, plus they often fail shorted, so I always think of how fun they can be in some places. Personally, when possible, I avoid them.

Makes sense.

Ceramics use to be more limited in uF or larger in size for an equal uF but theyā€™ve improved, less need for tantalum now. And no polarity to care about.

Sorry for the OT. Simon, you say that your version of the LD25 is 3000mA, 700mA and 80mA yet your aliexpress store says modes are 100, 40(1200mA) and 6% (180mA). Please update your store information.

sorry ,there is no star version LD25

I have two version LD25

Thanks for clarifying!

Did you ever carry/make a Nanjg 7135 driver that had moonlight low (I think it was 5mA mode) as well as H-M-L? I am trying to find a driver like this but can only find old discussions of it.

Are you not referring to the Qlite from IOS?

I'm not sure if these are low enough for you but are four modes. Supposedly .03 amp on low.

:_( I notice that Ric did not bother posting 17mm pictures, both listings show the 20mm version. Do you have these? If so will you measure the spring for me? Mostly Iā€™m interested in what diameter it is where it sits on the PCB.

Can do but you will have to remind me when I get home from work in 9 hours as I will forget.

Sure! If I had 9hr of work Iā€™d forget where to go home to.

Yes, that was it. I donā€™t think they sell them anymore. I do have an Atmel programmer somewhere but itā€™s just easier to buy a new driver.

Thank you for the links! I didnā€™t know about these.

AFAIK IOS and MTN both carry them.
