    The Bud Toaster - (currently: Model 14, version 3)

    Have you tried connecting drain and source, but leaving the gate floating? I get current. Idk. Breadboard failiure is definitiely possible. I will relocate parts on the breadboard.

    Lol. I know right? You should see how long it takes me to design my own stuff... I am using the same mosfet. I actually don't have the diode in there. I forgot about it. Maybe that's it.

    That is how it is hooked up. Even switching out transistor didn't work. I get current if I hook up drain and source up even if the gate is floating. It only turns off if I put it straight to ground. I even tried putting 1k, 2k, and 3k resistors in the signal line.

    I'm having problems with the transistor not turning off. I don't know why. The back side of the transisitor goes to the middle pin right? Drain. I'm pretty sure I have it wired right. When I set it up at school with a benchtop supply I can see it is 0A when off, but at home it always lets juice...

    I mean use the computer as a power supply.

    My real question is can u plug this into your computer and still use it? lol. That would be badass.

    I used the 12v rail with the new 12awg power lines. A .75ohm element for 16amps. Holy crap. Instant heating. My nichrome was glowing orange. The bowl I loaded blackened in like 5s. I could stick my oily tube in there for a second or two, then just hit off of it. It heated way too fast, so I...

    I'm having overheating problems with the transistor. I just had the solder melt and flow together on two of the pins, shorting the transistor. It was smoking after a second or two. How do you deal with the heat from the transistor? I am not at the pcb stage so I think I'll just get some copper...

    Hey, parts finally came. And it WORKS! Now I have my lcd version and your version both working and vapable. Once I get my hands on a camera I'll finally post my stuff and show you my vape chamber.

    The Maxx6675 are very easy to sample. So far I have gotten 15 off them for free. (they only give em out in 5packs). It's pretty sweet.

    Yo! Fuck CSS! MikroC FTW! Just pirate it. It's got a shit ton of built-in routines.

    To Usr: who cares if it ain't exactly 12v? 12v is to run the coil, so who cares what voltage it's at as long as its got good amperage. Even the pic doesn't care what voltage its at, anything between 3.3v and 6v works.

    The wire gauge is prolly it... lol The gator clips I was using were 22awg. I just don't have any 16 awg around. I think 18 awg is fine, since that's the size my power supply uses and it claims to be able to pump 40a @ 5v through them. But right now, unless I'm at school with a regulated 6v power...

    The power supply is not limiting anything. This is a nice PSU, it can supply 18A at 12v or 40A at 5v. I couldn't get it to work at home. But when I had it at school euning at 6v probing with an ampmeter and it only drew 3.3A, but it started at .3A and gradually increased. Idk wtf is going on. I...

    Is there a reason why the duty cycle starts out so low? I put through a 12V supply to a heating element that is less than an ohm, but I only ever get 3.3A out of it. Although it appears that it reaches the set point nicely. Woot! Gonna take it home and vaaaape.

    Is there a reason it would just turn off? I turned it on, then walked away for a while. It was heating up before I left, and then when I got back it was not hot or pumping any juice. The Led was doing the 3 blinks in 5 seconds thing. Does it have watch dog or somehting. 2 times I've turned it...

    I know the 5v is active and the pic isnt working because the lcd lights up, but doesn't show anything. Back to your model. I have it built right now, but the pwm isn't outputting. Even after I press button 2 for 2 secs and get one of the led's to blink on and off.

    What I meant was in my version. I know the pic doesn't turn on because it doesn't write to the lcd screen. I use a +12v line for the transistor and have the pic on a +5v line of the same computer power supply. But it freaks out and doesn't work. If I use a separate 5v wall adapter and the 12v...

    When I hook stuff up from the same power source it seems the heating element saps all the power, and the pic doesn't turn on. If your vape works , then this must not happen with your circuit. What about your circuit prevents the heating element from fucking up the pic? After thinking about it...

    What component of your circuit makes it work having the heating coil and pic on the same line. For my set up, if I power them both off of the same adapter it doesn't work. Where did you get your batteries from?
