If you want fully assembled and tested drivers reply here
Flashed and thermal calibrated MCUs are included.

This batch will be reflow soldered

Today 200 AMC7135 arrived and from last drivers I had 2 boards over
so i could fit the rest of parts to them, 21mm fully reflow soldered, 17mm resistors and Attiny25 hand soldered
need to use less paste especially on the FET, and add solder with iron to fets pad, as its not easy to push it down and hold still till the solder gets solid

you can choose soldering paste
recommended
with lead 62% tin, 36% lead, and 2% silver

*or *
lead free 96.5 % tin, 3% silver, and 0.5% copper

Oshpark has all boards from first order shipped, so it wont be long till first drivers go into production
Check the Excel screenshot if the information to your order is right, I keep it up to date dayly

Availiable options:

there are different sizes availiable 15, 17, 20, 21 and 22mm
those are cheap on the PCBs from Oshpark so I may end up with some unused boards
30mm and bigger are possible as well, but add costs depending on size

Information about this driver here
http://budgetlightforum.com/node/48447

There will be a very good SIR800 FET used
You can choose a custom number of 7135 less than the maximum

can be equipped with Attiny 25 or 85
running Bistro
or Narsil Triple v1.4 latest version with fixed bugs

For Lexel or anyone interested, I’m figuring out the support for adding R1/R2 LVP (2S cells) to NarsilTriple, but it will mean losing the Indicator LED support, so must be a compile switch then.

Drivers will be fully tested before shipped

Narsil v1.4 driver will be thermal calibrated as well
you can choose the temperature for stepdown,
the time for stepdowns depends on the lights size/heat, a Pocket rocket off a 14500 high drain will need a shorter time than a Convoy L6
standard will be 55°C
standard time between steps will be 45s

temp calibration with hairdryer

custom mode groups can be programmed for a small price depending how much to modify

ATM there are 2 main options for 2S Narsil for lights like Convoy L6
Narsil v1.2 utilising low voltage protection on pin7
Narsil v1.4 utilizing indicator LED on Pin 7, has some bugfixes and temperature protection
but Tom E is working on v1.5 where it is possible to choose between indicator pin and LVP

For 2S lights that use only a sideswitch or you dont lock out the light all the time a LDO is needed,
the zener mod has a very high parasitic drain

2S LDO is availiable for 17, 21, 22, 26, 30 and 46mm
2S Zener Mod is availiable on all sizes

efficiency advantage over Fet+7135*1

this is just an example, keep in mind that triple hotrods get more gain than a single emitter light

Springs for 15 and 17mm Board will be phosphor bronze
long

OR
short

For larger boards I recommend those springs

for 20mm and bigger a larger diameter spring can be used

Prices:

15-22mm
the Bistro Attiny25 12.5$
the Narsil Attiny85 14.5$
spring 0.3$
30mm add 1.5$
Zener mod add 0.7$
LDO 1.5$ 21mm and bigger only
LDO 17mm add 3$ more expensive part
Bigger diameter than 30mm I will build only if more than 3 drivers are requested
SRK size add 4.5$ if full 3 get ordered, if only 2 add 7.25$
SRK Size with more than 7 AMC7135 add 1$

2$ envelope shipping worldwide below 50g

according to this list there are 54 drivers taken and 3 reserved

originally ordered parts for 50 drivers,
but I got some more parts ordered so up to 59 can be build so its not to late to join in
I can do some more drivers but I have limited parts and boards sizes
