    Tired of manual switches? Simple Touch switch pass thru for under $15.00

    Yes kinda sorta if your talking about the first circuit posted in this thread you would need a Pchannel with pretty much the same specs as the NChannel and the same source voltage for the resistor values to work. It can be a bit confusing because later on in the thread there is a captive touch...

    Your Welcome, As far as heat it will run very cool compared to linear regs. Heat shouldn't be a issue at all with a switching reg. The added bonus is that they are quite a bit more efficient also , so less recharging will be required.

    Thats about as simple and small as it gets as far as adding a 3amp switching regulator with a onboard pot.

    My First Pulse Width Modulator Mod

    I know how that goes always something coming up getting in the way of progress. Was going threw my order and these SMD switches i got are just too damn small so I have another order i need to place. I added that Ti lanchpad eval board to the cart. I figure for $4.30 what hell might as well give...

    How do you plan on setting up the circuit. Do you plan on etching a board for it. The Atmel chip is really pretty small to be soldering all those wires to. I can design the circuit that can be etched into a board i just don't have the time to make the board and test it all out to make sure it...

    It would be lacking amps at higher voltages. You could get away using a 2 amp for regular ohm atomizers. But 1 amp is going to be pretty poor vapor production and might even kick protection in on the reg if it has it. Your much better off spending the extra bucks on the 3 amp model.

    Wanting to make a copper mod, need assistance!

    A easyer way is to just make sure your wires cant make contact. Really you only need to worry about the positive wires if your building a poorvari. This stuff here is cheap and a really good way to insulate wires. 9 Piece Heat Shrink Wire Wrap Assortment Heat shrink Tubing

    No you cant switch that one around. If i remember right ( been awhile since i have read the Data sheet ) The output on the ATMEL cant be taken low. Basicly that just means it wont put out a ground which the gate on a P Channel requires. That is why i was going to design a new circuit for use...

    Tired of manual switches? Simple Touch switch pass thru for under $15.00

    Well i am for sure no expert. I just did start looking into it. Mainly what i looked into is what they use for touch activated stuff. Since it related to a touch sense mosfet. never really looked into spikes. Hell i am not even sure i will beable to solder the 0402's but i will give it a shot. I...

    I dont know about larger here is a 30kV thats in a 0201 package.Digi-Key - F3572CT-ND (Manufacturer - SP1005-01WTG) Maybe I missed something but i didn't find any larger ones i though would work at my voltages. I for sure would rather solder something bigger then a 0402.

    Looks like the atomizer Goddess gave birth to some under developed atomizers. Not ready for prime time. Maybe with time they will grow some coils

    Reminds me of some prison movie where they fried a guy in his cell filling the light bulb up with something extremely volatile forget the name of the movie off hand. But if you want to know how it makes me feel, It make me feel like drinking a beer outa a light bulb

    Yup thats a good point you really dont want to use a FDS6679AZ below a 4.5 gate voltage. I would say slap a TVS diode between the gate and source just like a resistor for the FDS6576 but for our voltages they are small as hell. I guess a zener might be a ( bigger) better package.

    Actually i would go with a 10Mohm resistor @ 3.7 volts. 2Mohm wouldnt turn it on most of the time with a touch @3.7volts. EDIT: Yeah for sure a 10Mohm it will still work decent down @2.75volts which would be the cutoff for a protected cell

    I think it would work might be a bit touchy on the latching at that voltage. Might want to go with a 3 or 4 Mohm resistor. I can check it on the bread board and see how it acts at 3.7 volts with 2Mohm. I will report back in a bit with results

    Since am going to have on-board charging it will be connected to a ground at those times. Even so it is pretty unlikely the ESD discharge will hit the touch pin ( gate ) . More then likely going to go to the grounded case unless you pick it up just right. I guess it would be a one in a million...
