    What value of resistors do I need and a sanity check

    Thank you That is absolutely amazing I thank you very much I will get it and see about how I can begin building it. I have no idea what time frame but this is a great start and an excellent description. Thanks again What impact would going down to a nine volt source involve? I was thinking...

    What value of resistors do I need and a sanity check

    Is this circuit more reliable forgetting my potentiometer and the extra LEDS would this solve any of the issues mentioned previously. This one had advantages as it was made in a housing that was portable. If it is then I can try and add my stuff with the improved design you guys showed me...

    What value of resistors do I need and a sanity check

    This was the show that gave me the idea also.I also found another schematic.t I am redrawing it to place here to get some ideas as well I want to incorporate my switching into it.

    What value of resistors do I need and a sanity check

    Dave, I do thank you for your help your diagram is very good. I guess because I also put time in mine to get those types of responses to my very first post just put me a bit off. As far as your diagram it is very easily read and I understand what is being done. In KrisBlueNZ post he mentioned...

    What value of resistors do I need and a sanity check

    Well let the sarcasm roll I was just surprised to see it is all The project is TDCS or Transcranial direct-current stimulation here is a link http://en.wikipedia.org/wiki/Transcranial_direct-current_stimulation I can hear the laughing already. Anyway the lines labeled cathode and anode in the...

    What value of resistors do I need and a sanity check

    Hello Everyone just as an FYI for someone who is obviously not that knowledgeable like myself and to which I freely admit to in my posts some of the answers seem to have a great bit of sarcasm associated with them which does not go along way in respecting the people or their opinions. Maybe if I...

    What value of resistors do I need and a sanity check

    Thanks duke37 I appreciate your answer about using LEDs and how it would ruin the supply. Being somewhat new to electronics I did not know about the orientation of the LED symbol.

    What value of resistors do I need and a sanity check

    Sorry for the confusing schematic here is the original and mine for easier comparison What I want to do is add a switch so that the output current can be controlled either by the 4 way switch (shown here) or a pot and have built in meter to see the actual output in that part of the...

    What value of resistors do I need and a sanity check

    I have a question regarding this schematic. I am not that well versed in the determination of all the components I need but I do try. In the middle you see a 4-Position rotary switch on each of the terminal paths I want to have an LED that lights up AND I want it to be at the deisgnated...
