    HELP - resistors and dip-switch

    Guys Sorry I did not notice the connection in circuit3 posted above where missing, my mistake. Question still remain, where do I connect the thermistor, in the circuit 3, or in circuit forum lab 3, above ? ? ? ? ?. which ever is the better or more reliable of the two. I do have some 10k...

    HELP - resistors and dip-switch

    AllVol 2 Questions, please I am very greatfull for the help. 1. Where do I connect a thermistor to this circuit, to regulate the fans? 2. Why would the circuit I posted, from this site not work? Thanks  Virus  ??? ??? ???

    HELP - resistors and dip-switch

    Audioguru I have find a circuit at a quite informative site, http://casemods.pointofnoreturn.org/pwm/index.html and have attached the diagram, could you please indicate where I should attache the thermistor in this circuit?  Also I have 10 K ohm termistors, could they be used? Can their be...

    HELP - resistors and dip-switch

    Audioguru Again a eye opener from your side ! ! ! Just one question, if I opt to go with the resistors and the dip switch switching the resistors 1 at a time, what will happen if for example 2 switches are on at the same time ? Would a PWM circuit use much less heat. And how would I...

    HELP - resistors and dip-switch

    Zeppelin The whole though was that dip switches would be the easiest, but then the problem with the parallel resistor etc. Unless one starts with a higher value resistor? audioguru It’s the same circuit we discussed before with the thermistor emulation, I now put the thermistor with a air...

    HELP - resistors and dip-switch

    Hi guys Great gears for all the input. Pity, that the kid_kv, (http://www.electronicslab.com/forum/index.phptopic=6755.msg41336;topicseen#msg41336) could not see this amount of response. This sure would make him g r e e n. Well we know this is a great forum, with some real people. Back...

    How to simulate the heat generated in side a PC-case.

    Hi guys I have a PC power supply in side PC case. NO other components. I need a resistor or something ells, that I can connect to the power supply in the case that will generate the same amount of heat or even more inside the case, (should it be a fully functional PC).  I was thinking in the...

    HELP - resistors and dip-switch

    Thanks guys Will try out the different options and let you know. It could be that a miniature selector switch will do the trick. Still chewing on the idea. Thanks for the feed back. Virus

    HELP - resistors and dip-switch

    Hi Guys A million dollar question, and please I need help with this one. I know a little about ohm’s law etc. but still can’t figure this one out. Being a non electronic tech and wanting to build a fan controller and I need some expert advice. In the circuit I am building I am using a 10 k ohm...

    Emulate a 10k thermistor

    Hi Guys I need a circuit that would emulate a 10 k ntc thermistor, for the sake of endurance testing a product. As temperatures vary the thermistor will follow, by changing its resistance up and down between
