If I may give a hint: the ability to turn on and turn off the light in a “graduated”, that is not all together, but with a ascent (0% - 100%) in two seconds (or programmable), which is useful when you turn in complete darkness to get used to the eyes, especially in enclosed spaces. It could be a “ramping mode”.
Wow that’s a fast review! Only one day to get this amount of words and pictures. You must have spent the whole day since you got the Asgard on typing this. A couple of typos but no difference to the quality of this preview review.
Yeah, I kinda agree that after programming to the right modes, it’s quite likely that we would not be programming it for a long time, unless it’s to show friends or family what the programming could do. But nevertheless this is revolutionary.
Some questions though - hopefully the questions help 
1. PWM 31.25kHz or 31.28kHz? Noticed two values at 2 different places in your preview.
2. To connect via Bluetooth to the Android app, does the Asgard need to have batteries in? (I suppose so, but asking to confirm)
3. Turning on the flashlight through the app - have you tried?
4. For the modes, there can have multiple steps - how many steps can one mode have?
4.1 For the “profile memory”, is one step considered as one “memory”?
4.2 It is advertised as 30 modes, can it have more than 30 modes?
cool stuff. thx
Great review indeed John.
I know I've had my doubts on whether the bluetooth was anything more than a gimmicky feature, after seeing it all housed in the light alonside the fact it seems to be integrated as part of the driver itself, I'm coming around to the idea of it's potential value. The driver does actually look like a well thought out module (if still a little untidy) especially after having seen the PilotPTK modules.
As it stands right now, from my point of view is that the driver and it's technology is worth far more than the 'driver in a light' package. If fasttech want to add value to the package they will have to develop their own unique host with a bit of it's own prestige that can grow alongside the Flex family of lights.
I'm guessing customers are going to want the driver with it's bluetooth flexibility to integrate into their own designs, and with the added ability to stack 7315's makes it very 'Flex'ible indeed.
I hope Fasttech has patented the technology otherwise they'll be the guineapigs until the bigger lions further up the food chain take it away. And I really do hope that Fasttech have a change of heart and offer to sell the driver/software package as is because that's where the bread and butter is at and essentially we're not going to want to spend the extra dollars on a budget host that we may not want or need.
Thanks for sharing Johnny, it's highly appreciated
Thank you for the preview, Johnny! This is a very exciting development. I would love to see this technology in some other hosts.
Seriously, assguard? I would buy one just because of the name. The ultimate in personal security.
Nice write up Johnny, thanks for the effort. Makes me wish I didn’t just go back to the iPhone.
Patent? In China? That is effective.
Best would be a patent in US, UK, and Canada. This covers enough market to make it international. Expensive though, but I do hope they consider something. They have one year from public disclosure.
China have patents too:

Wow
Thanks Johnny, another interesting review.
Should I wait for the Beowulf ? Will it be a different body ?
Sorry, didn’t mean to suggest China doesn’t have patents. I was making a reference to how having a patent doesn’t do much to stop rampant copying.
Having patents in your major markets is far more effectibe than the place of manufacture. Also, even with a patent, you need to expend considerable resources in court just to defend it when you need to. Not fun, except for patent lawyers 
Great preview/review…
1. Could you post the size of the flex driver?
2. Like Gords asked. Are you able to find out what will happen if you stack a 7135 or a few on there?
US patents don’t mean much in China where they are not enforced. Chinese patents in China do, I’m sure, mean quite a bit. It will keep all the other Chinese cloners from stealing their idea. In the meantime, I’m sure the owner of Fasttech has applied for patents in the US and elsewhere as well. The man is no fool and, from what I’ve been told, is quite the legend in China. Think of him as a Chinese Donald Trump, Mark Cuban, or Rupert Murdock. I don’t think he is a fool.
The Beowulf will be a different body. It won’t be based of an existing light but will be designed and made exactly to their specifications. I understand it will be an EDC type light. If you want a good, versatile thrower then the Asgard shouldn’t be passed over. If you have zero need for a thrower then pass over the Asgard. It’s up to you but, like Pokemon, I’d wanna catch 'em all. 
What are you, 9? LOL! :bigsmile:
Asgard, is the name of the realm where the gods of Norse Mythology live. I think it's a pretty cool name for a light. ;)
I will answer what I can but will leave the others to Jasmine and her team of engineers that developed it.
1) I was told 31.25KHz. The 31.28 is a typo I will correct.
2) It has to have batteries in it and can only be accessed when manually set into BT mode. Not batteries, no electricity to run BT.
3) If you can turn the light on through the app they have not implemented it into the beta version I am using or I haven't found it yet. I believe it is the former.
4) That is one best for Jasmine to answer.
With 8 discreet non PWM levels of 12.5% would suggest that each AMC7135 is controlled individually by the microconttroller. Looking at the pcb picture looks to verify that. Adding extra chips would mess up the non PWM mode brightness levels, because those channels with the extra chips overweight their contribution to the overall brightness of the light.
In PWM mode there doesn’t seem to enough evidence on how they control that. If a single master PWM/FET combo is being used, then it could be no difference in mode brightness levels. If PWM is controlled by each channel, then brightness levels are still being messed up .
it was specified earlier that it has 8 chips that are individually turned on for 8 brightness levels without pwm.
it was also discussed about finding which chip would be the last turned on for mx brightness and adding chips to that one for a turbo.
johnny, any chance you could discover which chip is the last one turned on for max brightness? i wouldnt think they would be randomly accessed, but you never know
Couldn't you just add a chip to every single 7135 and then everything doubles, if you reworked it so it had a XM-L2 U2 direct bonded to a big copper heatsink it would be doable.
i imagine you could stack one on each chip… but im wondering if that would mess with the pwm controlled settings…?
What we have here is a whole new generation of flashlights….I’m both excited to see what wonders we shall soon behold, and thoroughly pissed off because all my lights are going to be obsolete by the time next winter rolls around…. :bigsmile: / |(
