thanks for the reply Dave. First question do Ti do a 3 lead transistor same spec as the fairchild i have looked but struggling to find one, also would the batteries drain alot when not in use?I emailed Craig he said the best option it to go with a mosfet?? and not use the inhibit pin. well thats the way i interpreted it. If a mosfet would be better again do you know which one Ti do for this.I have also contacted Ti and explained what i required just to see if they can shed any light on it..... as you well know electronics is not my fortéany and all help would be much appreciated as i would love to use a tactile switch with my TTS modThanksstyl3®update found this one on ti LM395T/NOPB http://www.ti.com/product/lm395orLP395 ://www.ti.com/product/lp395
Ok guys i think i have got it now is this right.... see attachmentAnd thanks again for all your help
Thanks for the reply yeah i didn't change the resistor value on the drawing but i do anyway. I now have another question about a on-off-on slide switch so i can isolate the whole circuit first on for voltmeter to display vaping volts then the second on position to show battery power. Now do i need to put a diode in the lead to the voltmeter so not to have the atty firing on 8v "possibly" see attached and again thanks for all the help it is much appreciated........ been looking at ti dc/dc convertors with mosfet built in but cannot find anything in the range we are after seem to be all low output current.
Dave you are a legend
I have 3 types of Digital meter including the one you are using.The attached drawing should work with NO diodes and a SP3T slide switch.
Yes I have heard that but it when like this: "You are a Legend in Your Own Mind"
haven't been around for a while been to busy, Just getting back into it. Been trying to find an answer for this question: using the ptr080100wvd i want to use a tactile switch so was thinking of using the inhibit pin 1 now the data sheet from ti doesn't really give any detail now. Using the original circuit that i employed in my TTS i showcased on here, of coarse using your circuit if i connect a biased resistor transistor on pin 1 grounded to pin 3 and input into the transistor from my N/C tactile switch would this work. This is what i thought of using but as you know electronics is not my fortéhttp://uk.mouser.com/ProductDetail/NXP-Semiconductors/PDTC114ET215/?qs=sGAEpiMZZMt32xmUYxteeQxveqxYnTDl%252bFH%252bnFHbDVE%3dor any info how to achieve this would be great ?thankskev aka Styl3®just looked at the physical size of this and far to small after something about 5mm+yeah i think this typehttp://uk.mouser.com/ProductDetail/Fairchild-Semiconductor/FJN4302RTA/?qs=sGAEpiMZZMt32xmUYxteee5LPI%252bR7nPURsaoVdycRvE%3d
Does it matter if the RDS value is high or low, i have shown one low and one high ..... never let an electrician do a EE's job http://www.onsemi.com/pub_link/Collateral/NTD4963N.PDFhttp://uk.mouser.com/ProductDetail/Fairchild-Semiconductor/FDB6030BL_Q/?qs=sGAEpiMZZMsrr1kXJis%252bJ%2fHyY0sDq83wc1YHCgNS3T0%3d
right i will try againdo you think this will work even though i know a little crude so i only need 1 slide switch for off-vape volts-batt volts using diodes so no voltage leak to atomiser when testing battery volts
Yeah I can't wait to see what you're gonna make with that new controller D! You are gonna show everyone your progress as you build it, right? Need some good entertainment in here....
How's the Berger-Miester's build going on the new controller?
just another quickie does the main on'off switch in the negative have to be at least 3 amps?
A 3 amp or better slide switch is required.
trying to get a 3amp as small as possible but not easy as space in the 18650 diy box is vey limited
thanks for that Dave, just a thought why can't i put an on/off switch before the tactile switch as the n channel mosfet will keep the system off unless the tactile is pushed so if i cut the feed to the tactile with an on/off that would surly do the same?cheers Styl3®
need some help guys i have wired the circuit as per my attached drawing.i have also wired straight to a supply without the tactile and slide switch and i get no power to the module or or output.thanks in advance guys
I agree... I would break either the pos or neg at the battery end with the on/off sw.
Yes it will work but why not put the on/off where breaktru suggested. This way you eliminate battery power to the board. I think it is a better way.Also you said:What happened? did you do what breaktru suggested? and what was the results. I'm very interested. Thanks styl3r
Styl3r, I see that you are making and selling mods on a different forum. Usually I don't offer advise to profiteers. There have been several others on this forum.
No shouting this is just putting it out there. with a mosfet we are breaking the battery supply, i suppose even better with a P channel mosfet as it cuts the positive but the N channel cuts the negative to the ptr or okr module from the battery. So as you said you agree with Breaktru about cutting the positive or negative from the battery. I am with the N channel mosfet breaking the negative from the battery. This is to demonstrate an argument in the technical sense that is.....thanks guys for all the input, and i have gone with a 3 amp on/off slide switch but just interested in other peoples views. And i suppose the best way to isolate would be a dp on on slide switch cutting positive and negative
