Thanks. Strangely, working on this project has become how I relax. I have a little more progress for you. So, I dove into setting up the power pwm for the heater control. First off, I can't believe I didn't burn anything important out doing this. The arduino and max6675 are pretty resilient...

hey all, been super busy. made some progress... that is with the 300W coil heater. I have the dc cartridge heater, i just wanted to make sure I had my controller working with this one first. I will make a test housing over the next week and a half. Then I can test the unit with the proto...

Here is the code I am running for those interested. Knock yourselves out. A side note: you have to reprogram the stock boot loader on the arduino chips in order to run the wdt, and I have not done that yet. All the other bells and whistles are in there, though. I wouldn't suggest using this...

I am using the PIC CSS IDE at the moment. As I said before, it is pissing me off. There are far too many buttons. They might be useful to me one day, but all I want is to monitor the serial port, compile my code, and program the chip. Maybe one day I will figure out what the other 800...

jack, if you are willing to have your heater outside the airpath, there are lots of options. Using bare nichrome wire is probably the best cheapest and offers the most design flexibility. Without the bells and whistles, very powerful cartridge heaters can be had for less than $20 new. Also...

jackalope, tough to say whether or not that is a good idea. It all depends on the unit and what is inside it. If nothing else, it sounds like a good way to try this out without dumping too much money into it.

HD, Thanks. I'm just glad it came together that quickly. In reality, it doesn't matter that much, because the 12 volt heater is what I care about. It is definitely nice after all that work, though. Here is how I understand the heater choices. Either I do what you do and have a heater...

vap, Good question. This heater was a total pain to find. In fact, I thought it didn't exist two weeks ago. The reality is quite the opposite, but let me explain. My first try at getting this heater was with high temp ind. Those guys sold me the coil heater I am using now. He said 3 and 6...

ok, update time. I have been busting my ass on this. Luckily, things are coming together pretty well. As far as the controller side goes, I got myself the arduino duemilanove usb board and worked my way through "Getting Started with Arduino" by Massimo Banzi. I then built the control...

Yeah, it is pretty large, but, then again, I have no intention of using it in the actual vape. It will be great for prototyping, though. Especially since I would probably spend days trying to solder just one of those tiny pins on the max6675. You should have seen my face when I first saw one...

Looking good. The glass vial system looks like it works really well. It is especially nice since you can pack a few of them, cap them, and take them with you. Whatever I end up with will have to have a cartridge system like that. Tough to figure out, though. On another note, I found this...

ok... my mind was just blown. I just learned about something called arduino. http://en.wikipedia.org/wiki/Arduino Arduino is a system that has been developed to make working with micro controllers more accessible. Instead of programming in assembly, or even C, you work in a modified version...

hell yes. that looks sweet.

You are right, a brake would be best, but don't forget that you can buy all sorts of different types of vice jaws. Again, I am just trying to think of low cost solutions. Nothing beats a properly outfitted shop. As for the different warping rates, you could use aluminum on the top and bottom...

HD, I disagree. Each version looks significantly better than the last. I think you are closing in on a good solution. If it were me, I would be looking to start with a large block of wood and pocket it out one way or the other. Maybe start with a large middle portion that you drill straight...

vap, that's a tough one. I'm not sure you will be able to calculate that without a significant amount of digging around in heat transfer books. I would suggest doing it through experiment. I will look around, though. -skippy

Hmm. That will be very useful once I get down to writing code. That is still a ways away, though.

B1, B2, B3 tactile switch RK73H1JTTD2001F Not that I desperately need the part number of your tactile switches, but I figured I should point out that one of these things is just like the other... and shouldn't be. Thanks again for all your help, -skippy

"This is the first empirical data I have seen comparing actual hit length and average air flow rates. That you also include the amount of heat (watts) needed is a bonus." You don't see it posted because it will never be a perfect guide and it is a pain in the ass to collect. Although, I...

I don't even attempt to do that stuff in my head. I have already screwed myself so many times doing that. Here is a pic of the rotameter: That's SCFH, not SCFM. Just to avoid confusion.
