OK, guys, breaking the rules a bit I'm doing another post right after the last. However, this is an entirely different topic and a very important one and think there will be a LOT of interest. Please indulge me?
So I just got back a bit ago from a second run over to TV to meet 'the boss' who outlined some truly exciting stuff coming up. Much of it Tim has been hinting at, some of it I'm not so sure I believe.....yet. I'm assured all will come out in due time, but I expect some really exciting prototypes to test in the next few weeks. Hope, hope, hope.....
Now one of the more modest (but IMO very cool) ones I've been OK'd to discuss: Low Voltage T1. I have one right here. It's four hits old. WOW!
Some months back I was given a series of LV cores to test, five in total I think. Mixed results and I found it harder to control than the SV version and offered no other advantages than using the 3.7 Volt battery rather than the two 3 Volt ones from T1. I assume the other testers found the same things, they seemed to know what I was reporting already. It had the same 'needs lots of power' problem T1 has so by the time you were pulling enough current from that poor 17670 to get it going well, battery life was no better and it was still a little slower to get going. Noting to get excited about, which is why I guess they didn't move forward with it.
Enter a different heater design. Much different, really. A single coil of much heavier and longer wire. And only one heater. It still has the same ceramic core in it, but the wire is now no longer touching it but 'free in space' inside the core. Air can now flow all around the coil, not just over the outside. And here comes the fun part, much lower in power!! Like half the power of T1 and yet it works just fine with modified technique.
First off, it warms up slower (like LV Revolution is slower than SV), maybe 5 or more so in step 1. I'm preheating 20 seconds by the clock right now, not my usual 15. After that a normal 'warm up pull' for step 2 to a good test puff. My first four real hits are really real. So much so, further testing has been put off for a while......
Here's the real fun bit. Based on 'back of the envelope' calculations we're talking about something on the order of half an hour of total heating time! Yes, I said half an hour (26 minutes to be exact). By the same calculation T1 is looking at six minutes. You do the math from there. Even if the hits take twice as long (I think it's more like seconds longer out of half minute hits) you still get twice as many. Rather than 10 or 12 hits to clear a bowl, I expect two or 3 dozen! Maybe more.
Time will tell if it's been cut back too far (my first four hits say that's not the case) but IMO it's gold right now. Tim will be putting them up as loose cores. Take your SV core out, screw this one in, swap the two RCR123As for a single 17670 and you're in business. Takes a lot of the wait for 18650 based supplies out of it IMO. And cheaper too.
I don't know if everyone is willing to wait a bit longer (not all that much IMO) for 2 or 3 times the hit count, but I am.
Another interesting thing I was told to look out for was 'blue smoke', the vapor is definitely more blue (rather than white) than I'm used to. I'm not sure what that's all about yet, but I'm told it's a good thing?
The bud I threw in was some I'd ground for MFLB so it's probably dryer and finer grind than most, perhaps not optimum. More experimenting is called for, but I think this one's a winner for sure. I'm not planning on giving it back, and that's for sure.
More when I have more to offer. But keep tuned for Tim putting up the LV T1 core (along with some other cool stuff) and be ready go jump on it is my advice right now.
