    How Can I Resist?

    Hi- your suggestion to have each have it's own resistor is, I agree, the better solution. Yes- I just want all three to turn on when the pedal is clicked.

    Power supplies are notoriously flakey. Don't assume the other one you replace dit with, was in good shape- if it was used. The symptoms you are describing point to a failing or failed power supply.

    Toast or Useable

    Many years ago, when police scanners were popular, I purchased a Uniden TrunkTracker 3. I remember that it was expensive. I still have it, and it is in very good shape as I hardly used it. I realize that everything has changed where the world of scanning is concerned. Is this unit completely...

    How Can I Resist?

    I am working on my guitar pedal and I need to figure out what size of a resistor I need to step down the 9 volt power supply in order to light up three LEDs that are run as follows: All three anode leads are run in series to one another All three cathode leads are run in series to one another...

    You likely havE a power supply that is on the verge of failing. Did you swap the power supply with anew one?

    Looking for direction

    I am, new to this too. I have been building distortion pedals for guitar. It’s a useful and rewarding project and my trials and tribulations are well documented on this site. Might be a good project for you. The people on this site are very helpful. Heed Harald’s advice. There are a lot of...

    The New Model

    So, I had a new idea. Enclosures for a guitar pedal can get quite expensive, and are sometimes too small for through hole work. So, rather than spend $24 on an enclosure, I bought 4 junction boxes for $11 at Home Depot. They look cool, (in a rustic sort of way) and they do the job. Have a...

    Is this possible to do?

    Thank-you. I have already built this and now its wire is snaking through my desk. I will try a different build next time I rearange my desk. It would be difficult to retrieve at this point.

    Is this possible to do?

    That's worth doing. Thank-you. I will have to see if I have one. Is it possible to use some sort of tri-color LED that would shine a different color depending on how much voltage it receives? P.S. I have a bunch of Diodes. How would I know if a diode is a Zener?

    Is this possible to do?

    Thanks for your help. It worked. I used a 47K resistor and a blue LED. When the line is not in use, the LED is bright. When it is in use, it dims. It would be better if it were the other way around, but it still works and is useful.

    Is this possible to do?

    Hmmm. I tested the line with my multimeter. When it was on the hook, I got a reading of -50.1 v DC. when it was off the hook, it is -5.1 DC. Note that these are negative readings.

    Is this possible to do?

    Thank you crutschow, I will report back once I get a chance to do the measurements

    Is this possible to do?

    Would this work: you figure out how big of a resistor it would take to safely light a LED, assuming a 48 volt power supply. Then install it in line with the green wire, Presumably, when the phone is not being used, the LED is at full brightness. When on a. Call, it is dimmed?

    Is this possible to do?

    If I plug in a phone jack and put my red probe from my multimeter on the green wire and the black probe on the red wire, will that give me the on the hook reading? And then make the same measurement when a call comes. In and is picked by a phone using another jack?

    I don’t have a clue what sort of schematic to use and I don’t have enough know how to figure it out

    Thanks Bluejets. My phone line has nothing to do with the phone company. It’s all internet based

    I found this one, which looks easier- but what is a 2A Bridge? https://www.circuitstoday.com/telephone-in-use-indicator

    Is this possible to do?

    I have hunted around the net, and have found various schematics that may do the following, however, I am looking for a simple way of doing it using parts that are commonly available. I am looking for a way to hook up a LED so that whenever our phone line is in use, it lights up and stays lit...

    Now the Fun Begins

    my stage gear consists of a Fender hot rod deluxe tube amp, and a suite of pedals. Fulton ocd distortion, boss chorus, boss digital delay and tuner. I have been there and back so many times with boss multi effects boards, Helix, Line 6 etc. I have learned that it is best to keep it simple and...
