Sorry, just have mention a little error.
That is a bluetooth antenna not a thermal sensor. The antenna on the pcb must have not been adequate.
I was thinking the same thing, antenna. BT is very low power, and it probably didnât want to go through all that aluminum. It has a better chance up near the glass.
Johnny thanks for the review,this type of technology is a game changer and should give us what we have been wanting for a long time.I personally am not too crazy about the host,however this "Beowulf"has my attention.The never satisfied with stock flashlights side of me was just thinking...oooooo,I can stack more 7135's on that board!Yikes somebody stop me!
LOL! you arenât the only one thinking that! 
:bigsmile:
From earlier posts, that (Bluetooth) was also why they had to go with a plastic reflector⌠the aluminum reflector blocked the signal. They probably put the antenna where they did (between the aluminum head and the plastic reflector) because that was the only âwindowâ that they had.
Hmm. Since this light uses PWM, I wonder if that (or harmonics) causes any problems with the BT signals?
Really?? WOw! Good to know. Knowing that it had a thermal monitor I just assumed that this is what it was especially after seeing the BT antenna inside on the driver itself. I will update accordingly.
Itâs not clear from the review if the emitter is even on when connected via BT. Iâm guessing it is not, in which case it would not interfere. The power fluctuation would be an issue I would think, which is why Iâd venture the guess of emitter off while communicating. Maybe not though, maybe its fine with it. Not sure what the point of a temperature readout would be if you could not read it out while the light is onâŚ
Johnny sollie for asking but is THIS your "review" of the Asgard, or is it really only a PREVIEW and you're gonna deliver a full fledged REVIEW ;)
a few thoughts.
1. I really really really really cant wait for my founder edition to get here now. This looks awesome.
2. I hope they decide to offer that contact board and the host as a kit, along with convincing someone to make a sinkpad esque 25mm board. As well as offering the alternative body tubes as stand alone items. Many zy - t08 owners would appreciate these various parts.
3. Have you asked what effect chip stacking will have (if any)?
4. Will we have the option of nw and ww emitters like the convoy and roche lights in due time? I feel that this would literally blow the name brand manufacturers out of the water, especially considering the starting price point.
5. Is there a possibility of the driver module being sold as another component? And if so, what are its vitals? I already know about the connectivity limitations (a/r lenses and alu reflectors) but they are easily over come by any modder - simply remove lense and reflector for the programming stage, as you say, once you hit on your various perfect profiles, its unlikely youâll be programming every 5 minutes. On the other hand, who wouldnât pass up the opportunity to modify some of their existing larger hosts with this technology?
Good preview johnnymac, Iâm as excited about this as you obviously are and wish fasttech all the success in the world, again, I cant wait for mine to arrive now.
If I may give a hint: the ability to turn on and turn off the light in a âgraduatedâ, 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 âramping modeâ.
Wow thatâs 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, itâs quite likely that we would not be programming it for a long time, unless itâs 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 âprofile memoryâ, is one step considered as one âmemoryâ?
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 didnât 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, didnât mean to suggest China doesnât have patents. I was making a reference to how having a patent doesnât 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/reviewâŚ
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?
