The World's Most Advanced AMC7135 * 8 Driver

Haha.. Alright, I'm not really sure it's the world's most advanced, but It's pretty awesome..  And yes, it will be available for purchase to people in the BLF community..

So, what is it?

  • 17MM Diameter (Technically, 16.8MM +/- 0.1MM)
  • 8*7135 (380mA each) 3.04A Driver
  • Each AMC7135 Individually addressable (means 8 Steps of Brightness with ZERO PWM)
  • Optional PWMing of one chip gives 1023 levels of brightness in between EACH of the 8 Steps above
  • When in use, PWM Frequency is 7.8Khz
  • FULLY Programmable.  Pick your modes, pick your order, select memory or no memory, tons of options.
  • Moonlight Mode WITHOUT PWM (2mA Current) (Can be changed by replacing one resistor)
  • Can be programmed to change modes via Power Cycle (Standard Tail-Cap Clicky) OR via a Momentary Contact (Side-Switch)
  • Temperature Monitoring (Programmable Temperature) (Either shut-down or reduce brightness can be programmed) 
  • Voltage Monitoring (Programmable Voltage) (Either shut-down or reduce brightness can be programmed)
  • Voltage Warning (Two Programmable Voltages that will output a blink sequence alerting you that the set voltage has been reached)
  • Modes are locked based upon OFF time rather than ON time (Much Nicer Mode Locking)

So.. Ok.. It's cool so far, but not that cool, right? 

What makes it so awesome?  It's got a micro USB Connector on it.  Yep.  USB Programmable.  No Clicking through 8 bazillion menus, no need for a Chip-Clip and AVRDude.  No Compiling your program in AVRStudio.  Just Plug it into your USB Port, Launch the custom application I wrote, Select all your options from drop-down menus, and click "PROGRAM".  Presto.  Done.

This is what happens when PilotPTK has more than 20 minutes of spare time Smile

When's it going to be available?  Soon.. I have a bit more to tweak on the software.  Hardware is done.  As soon as I'm sure the software is going to work without any hardware tweaks, I'll order a bunch of circuit boards and parts..  Once I'm closer to being ready to actually sell them, I'll create another thread in the For Sale section..

Some Photos:

AMC7135 Driver Detected by Windows.  Getting Microcontrollers to communicate natively via USB is an exercise for a masochist, I might add:

 

Top Side of Driver:
 

Bottom Side of Driver:
 

Even with USB Connector - Driver still fits just fine in a P60 Pill (Cut-away so you can see in)
 

I am currently extremely busy with work. Please do not expect a response from me quickly. I will be dropping in as time permits, but the amount of time I can dedicate to responding to topics and PMs is very limited.

This sounds fantastic!

Will it be possible to "limit" the maximum current through software to make it suitable for XP-E/G or Nichia 219 for those who don't want 3A output?

I hope you can find a way to sell or patent this to some of the manufacturers who continue to offer that crappy H-L-S option.

Oh! Nice! Smile

This may be a noob question but is it possible to stack additional AMC7135 chips in it?

I imagine you could just keep high mode set to 6 chips, or what ever you want max

You had me at the 4th bullet. You are a driver god to whip this baby up in short order! The only way it could be better is to make an optional version that works with an electronic switch. You are the MAN!!

Can't wait to see it finished. I'm in for at least one and probably several depending on price. Wink

In for a handful!

Edit: This is seriously the best announcement all year. Trumps the XM-L2 hands down. PilotPTK you are my idol.

You might want to make it a smidge over 17mm so it can be used in press-fit aluminum bodies. Sand to fit…

Wow. You are certainly one clever bugger. Nice work does not say what you have done justice.

Maybe, but wanting to know if there is way of noobie/kid-proofing it?  Laughing

Wow!

This driver sounds awesome!!!

I’d be in for anywhere from 2-5 depending on the price.

Frickin awesome. Big Smile

So.. it would also be possible to adress individual LEDs? Running light on quads or triples for example?

I'm pretty sure I'm in for one.

How many extra chips can be stacked on it? 8, 12, 16, before there is an issue? I'm thinking of those guysUndecided that like to hod rod everything.

 

Sounds really fantastic so far. Great accomplishment.

As it is now, I doubt that would work as that would require a ton of extra output pads, but I imagine with some careful soldering that could be done.

I'm pretty sure that would be like a normal 7135 driver, as many as you can fit on it. Wink

Exactly what I have in mind when I was doing my DIY driver.
If only you can place the USB connector on the VBat spring side so that you don’t have to remove the driver to re-program. Love it! Beer

This and texaspyro's SRK driver are going to make me very happy with my flashlights.

The low mode should be lower.

Please put me down for some, like 5-10, of these. Depending on the price, of course. Smile

When the price isn't mentioned, I always assume the worst... but if it's around some number which I am not going to mention lest it be ridiculously over or under the actual you can count me in for some as-yet unspecified quantity.

 

 

What's next? Programmable 12-18v buck driver? (please?) 0:)

That is a fantastic driver for almost every need. But my first thought was: when every 7135 is individually controlled, by cutting some traces this can custom control the color mce/xml Smile

Yes, absolutely.  You can turn on 1, 2, 3, 4, 5, 6, or 7 Full AMC7135s plus run the 8th one between OFF and ON in 1024 increments (PWM).
