    DWD - EP Multiwah footswitch

    I don't know where to connect the terminals. I have a board with no schematic that says "input goes here", "battery here" ect. Me? I would connect the battery in the wrong place and bunr something up! I wanted a schematic, but I couldn't find one... I can draw one, I knwo what...

    Power supply

    You want flashlight batteries to light lights. Even an LED needs some support. figure 1 amp per LED, and pot the volts so they will dim. meter it. Make sure the scope is within tolerance, then use a variable resistor to attain the meter.

    supply voltage for the sensor

    I didn't know that sensors could be connected to power sources. I thought sensors were impelled, initiated within a circuit, and that if you charge them, they would fail. Could it be that your test worked, but in the creation you put power to the sensor and blew it out? don't know, but i did...

    What size fuse would I put between D and F in the block?

    milli wow! Hey my figures were close to the 20 you said, the board resistors came out 21.2ma! OK I have a 9v 450ma I can use, but I might need to add some filters. alright! here is my latest schem on the test modes... I don't like the first test, because it uses the block for a power...

    current rating... ahem, how do I compute the current... That would be the amount of induction?? like a 500 induction coil would draw 500ma? if thats true, then 1.2amps would be just right. I have a 450ma wart, is it possible to increase it to 1.2?

    help with a small project - precise 1rpm motor & circut

    just another thought invariability is what you are after, you need to be more accurate than electronics alone can provide, and yes, you have to use a stepping motor, but I had this idea last night... I remember something about building a stepping motor with caps. why not cap the stepping...

    DWD - EP Multiwah footswitch

    assumptions, what a conundrum! Assuming... I am right in that the caps are the 5 way tonal changes... then the rest of the circuit must be inputs, outputs and switching. If the 2 1294s are power caps, instead of wah resistors, then I think it is safe to assume these are the pins that are...

    Basic Circuit.

    board layout, oh yes! always stack your components together, caps here, resistors there, amp circuits here, make sure you lable the board as you go, put lines on the board that tells what circuit is where... amps here, rectifiers there, induction there.... Then they change the entire thing and...

    how many Ma of wall wart would be good for this board?

    help with a small project - precise 1rpm motor & circut

    Hey, I always thought that a motor that turns a higher R would be better for a tracker plate... that if you geared it down exponentially, and then used a standard dimmer switch to increase or decrease the power to the motor, causing it to speedup or slowdown.... it only has to turn one way if...

    found a bad resistor.... This resistor does not look bad, but I cannot get a continuity signal through it. checked some other components, then tried it again, and its not blown? call the ghosts of the pcb controlling agency......

    9v...power supply Ok. I always thought that the power source was isolated with caps to keep it from burning up the other smaller components. what are the 100v and 16v caps doing on a 9v board?

    DWD - EP Multiwah footswitch

    On this diagram I added the possible wah connections and the mains. Main A is always isolated, which as I remember(from school), must be isolated, for the circuit not to ground out.. I don't know what goes in the mains though. :( IDEA!!! Is it a harness?:p

    DWD - EP Multiwah footswitch

    forgot schem! the board has 6 large holes A B C D E F A is isolated B is connected to one of the CEcap's after the cap, into the base of the transistor C is isolated to pins A and H D is connected to .01 cap and pin F E is Isolated to Pin G F is connected to the other CEcap, after the...

    Properly connected board? This schem shows where I think I would put the wah pot and the battery, but I don't know where I would put the jack inputs and outputs. It also has a battery isolator for an external 9v wall wart. The 5 way works, but the plastic has pulled away from the potmetal...

    RS 348-447

    Not Relay, Solenoid. That really looks like a solenoid to me, maybe the S in RS stands for Solenoid could be a combo---RELAY/SOLENOID... like do a search for solenoids.;)

    updated schematic I made a few mistakes on the last schematic I posted... this is an updated version... I will keep looking until I have it right.
