Thanks for the reply Atomsk
I understand what you are saying. I know the how delicate th Persei is and its a fine tuned hy-bread.
I'm using 5ohm carts and have primed them correctly. I've read many pages on this thread, mosting in the beginning 50. Man with 393 pages there is no freaking way I'm reading it all
First, I tested the card. Next I loaded the funnel and BHO. Then heated it per the instructions. If the bottom ever got hot. I used a wet napkin to cool it slightly.
Let it sit (thats a big key cause the material is thick and runs down slowly bubbling). Air must release to allow it to drop.
So I heat it until I smell a little vape smell. Stop. Sit and wait. Repeat
After it gets all in, I then heat the cart by itself still holding on the bottom. I never let the bottom get so hot I can't hold it. If it starts to rise, then wet towel... Let it sit and cool.
Test with 18650 battery (had to run around town to find one thanks to the dead one I got plus plantvape.ca was out otherwise I would have bought a spare like the 18350's I did
)
Repeat with torch
repeat test (repeat torch and test until it draws. then let it cool again)
Test again and get a good but light draw with the 18650.
Move to the 18350's and try it. OK it works about the same as the Micro-G (not the G-pin). The micro-G really works well. I figured out how to load it well - place a piece on the heating coil. Pulse the power and allow to melt into the wick, add another, repeat - this give 5 good draws very similar to a single 7.4V 5 ohm.. Since the coils due wear like the Omicron carts, I just bought 4-5 extras. I load several and found a little rubber cap for carry. Now in seconds I can change the coil and boom, ready again. However, the 4-5 good draws puts be down. Next, I carry the portable charger (it has its own battery) to recharge it on the go. Its made for the Ovale, but the Micro-G is the same. Why I say this was I was pretty happy with this setup, but having 1/2 or better yet 1g of material in the cart is a great feature plus with the dual cart I was intrigued. After the Micro-G my expectations were high I guess...
With two carts it does give more, but having two tips isn't the best and is problematic in my opinion. A single tip would be better. I just threw together my own using the Omicron tips, plastic and rubber tubing. Now it works much better... Yet another item to buy...
While the quality of the unit is good - its clear to see they put detail in it. However, I really don't think its ready for prime time yet. Its a prototype with a horrible user interface - like PC-DOS in 1981. I am also disappointed after a year of release it still pretty much a prototype. That's bad in my book. Instead THC S... have diluted there work on more and more products instead of finishing the one they have. The base unit needs work.
Sure you can use it and most for the advanced user. Being a old senior electrical engineer with many designs under my belt (systems etc - I design ATE to test IC's on the production line - Intel P's are tested on the equipment I was a hardware architect for. Not ringing my chimes, just giving information to show you where I am coming from and that I may know something
)
Bottom-line the interface is primitive at the least. Basically a ON/OFF switch. Plus you must change batteries to change the voltage - Oh come on guys! Lets move into the modern world here.
In my opinion - that and $400 may get you a Starbucks latte) it needs the following improvements to justify the $200 price.
A electronic controller that does the following:
1. Give voltage control for the full range of the batteries (if the 18650 goes to 4.2V fully charged,
then the controller can regulate down if you want 3.7. Same goes for for the CE123A's and 18350's).
2. Have wattage control (verses the voltage control). This is really what you want. For the 5ohm,
just set to 10-11W and if the voltage spikes, then the control regulates it.
3. A prime mode program. This program sets the wattage to just a few watts for priming.
Next, it pulses the power automatically to prime the cart. Wattage control adjusts for the cart
resistance automatically. THCS can characterize the carts etc and design several programs based
on material type and resistance.
For extra credit throw in a thermal diode and have feedback so the temp is monitored and kept
at the optimum temp for priming.
4. Use program modes. Again the unit pulses. Several programs with varying on/off times characterized
my cart type and wattage selection.
Again extra credit to add the thermal couple to add feedback.
5. Finally get rid of the cheap POS charger. Having the electronics built in to charge and just require a
cable (not use USB would give enough power, but a wall transformer/cable...
I had high hopes after reading THC S's early posts about this unit was designed for heavy C's unlike the others that were just re-marketed e-cig technology. Yes it is, but only a small step in my mind. It lacks integration and puts all the effort in the users hands. This makes the user base smaller and really only for the most tech-o-crat advanced users who don't mind the learning curve and the extra effort.
For me the real core technology here is the cart, not the base unit. The unit design is really sub-par. Even the battery adjustment is low tech brute force. Don't get me wrong, I welcome KISS, but a mechanical adjustment should be self-adjusting on this. Hell the charger is and is < $10 (yes its a POS too). The units electrical setup is just a on/off switch. Zero electronics. I don't know about the Omicron, only the Persei. The thermal couple would be simple and in the base unit. It would measure the battery connector temp and since the physics of the SS heat transfer is well known, the temp can be calibrated to measure the cart temp at the area around the heating coil.
Doing all this would open the market to many, many users and reduce the use issues. Until then they are just treating symptoms and not solving the root issues.
I bought the full attachments, the Nibbler-X, the Bender and 15 carts. Yes spent $$$. Didn't get the Hercules unit because the 7.4 doesn't seem to be available. Looks like I still need a dual-single tip and good batteries to be complete for me. Part of me says just return it and wait for a better design. Meanwhile use my programmable wattage battery (6V max 1300mA) and 510 adapter. This gives me the features I believe are required. Don't get the low ESR (effective series resistance) batteries like the IMR's so the performance may not be as good, but its like $35. Just use lower resistance carts... Also the attachments don't require the base unit only the carts. I would be interested in trying the Hammer with a programmable pass-through battery while connected to a charger. The Hammer drain would over power the charger some and not having a low ESR setup may cause issues, but worth a try. A battery mod would solve that. Its only $50. As it is the base unit is very, very over priced.
I'll deal with the poor and problematic IF cause I can, but it needs work to really be a top performer and live up to THC S's "its technology designed for heavy C use from the ground up..." comment.
I am trying to give constructive feedback here and just not slam the company. That's my only motivation cause it they created a unit that added this functionalityI would be all over it. My Extreme-Q only cost $240 and is light years ahead in technology.
OK THC S got back to me on the ticket. Their response:
thank you for contacting us, The reason we do not warranty batteries is because people purchase ne batteries and call and complain that our batteries are dead on arrival. After marking the new batteries discretely we found out that people were sending in the old pair and claiming that they were the ones purchased. If you want us to make an exception and switch them, you have to send us back both your old nonworking pair, and the new pair that you purchased.
So now I must send all my new batteries back to them to prove I am not trying to rip them off even through I have had them 48 hours plus they "discretely" mark them to tell (i.e. no need for the other set to prove they are new). Plus pay shipping on a $20 item (that like 30% its cost), hve no batteries until I receive the new ones back or just use the CR123A I ran around town finding. Its not like I can't prove when I got them 48 hours ago.
I'll give them a chance to make this right, but unless I get this resolved quickly and w/o costing me a dime I'm returning everything (all $600 worth), calling my CC company and creating a dispute. Don't have time to do a tit-for-tat with a manufacture on poor quality and as it seems so far poor service. After reading the pages here I expected a lot more. I'm starting to wonder if some of these post here are genuine.
