    Frequency generator, level adjust

    I need it to be running at 1v peak, I do not know the resistance of what Im using, its a 3vdc transistor radio a friend of mine used a variable violtage regulator to do this, but I think I want a more basic way to do this

    Frequency generator, level adjust

    Im using the xr2206 as a square wave generator, but the voltage output of this is too high. How can I bring the voltage output of this down, without distorting the signal? Thank You

    Servo Stop and Reverse

    Their problem is with those is that I wish to enclose these into something, and when those units that you mentioned power up, they power up in a mode different than the mode then the one that I want them to be in.

    Servo Stop and Reverse

    There are many different circuit diagrams to run a servo in forward and reverse on the internet. Most deal with using a 555 to generate pulses. I would like to add a way to stop and reverse the servo at a user-defined speed (via Potentiometer), at the end of its path at both ends of the servo...

    6Vdc UPS, Battery Charger for AA Batteries

    Im looking for a super simple (as simple as possible), UPS that will also charge any sort of AA batteries, to a approximate capacity of 3 amps or so. They can be Nicad, NiMH Batteries, whatever you think is easiest to use, and charge, as I have not purchased the batteries yet The UPS doesnt...

    Random digital potentiometer driving

    I have posted a 4017 controlled "network" (cannot think of a correct description of it at this time.) This is the beginnings of the route that I think I will take. Hevans has hit the perfect description of me: "I fear that the OP who initiated this thread might be neither a computer weenie...

    Random digital potentiometer driving

    I am using the generator to tune a radio that is not using a variable capacitor, but a potentiometer (as so many are now, on inexpensive Asian radios). This I can do successfully, and am doing right now......(I can send you pictures of this if you do not believe me...LOL). I simply want this...

    Multiple LED Driving

    For a Non-Professional guy, just screwing around, The LEDS there are fine for my purpose, and the prices are in Canadian with free shipping

    Multiple LED Driving

    The 6vdc is a high amperage battery, and the lights are switched using a simple logic relay, switched on and off by a circuit Thank you for your reply Kim

    Random digital potentiometer driving

    If I end up using 2017s, I will start with its 10 outputs. If that works, I will go forward in a resolution that is a multiple of 10.

    Multiple LED Driving

    The one thing i can never get my brain around is that multiple leds in parallel, does each led need its own current limiting resistor??? Thanks, Kim

    Multiple LED Driving

    You are correct, they do not, but a general everyday guy, doing general everyday fun stuff, for myself, and sometimes others, they are perfectly acceptable quality

    Random digital potentiometer driving

    It doesn't help that you do not need that resolution. Which resolution do you need? as an experimenter in this, Im not certain what resolution I actually need, until I get down to trying it

    Random digital potentiometer driving

    To be honest, I would like to have the circuit be as sloppy as possible, so that if it misses it once, it would get it in subsequent scans
