    Restoring a FOXX FUZZ-WAH

    The red yel wht brn blocks are 0.22μF capacitors (actually two bands of red together and see http://www.petervis.com/electronics/capacitor/capacitor-colour-code.html ) which I would guess are the two 0.22 capacitors connected to the 2 pole, 2 way selector switch. The picture of the pcb would...

    Help with simple circuit; wireless torch

    With modern electronics of all sorts, things are not always what they seem. Something strange would seem to be happening with your circuitry. The only real way to figure out what is going on is to have a full knowledge of all your circuits and logically work your way through what is happening at...

    Can someone help me with explaining a part of this circuit?

    Well, name... you must know what sw3 does, surely? And if you don't know the basic monostable action of the 555 timer, and you are interested in electronics, then there are lots of notes on it on the web and in text books. It is an excellent place to start when learning electronics. If you are...

    Water detector with NE555

    If this is an educational project, you may be able to get extra marks by mentioning electrolytic erosion if you have time. Look it up. When you pass a current from one electrode to another, the metal on one of the electrodes will be eaten away and deposited on the other. To avoid this in an...

    Can someone help me with explaining a part of this circuit?

    Where did you find the circuit? If this is a class homework question, I will give you a clue. You don't have to explain how the circuit works but why the 555 timer is irrelevant. Alternatively, the Thyristor is not appropriate. I should have asked, what the circuit is intended to do.

    Use AC Tap From DC Power Supply

    Without seeing any of your circuit diagrams, I would think you would be all right as long as you don't try and use the ac and dc supplies at the same time on the same circuit.

    Measure the current of 3 phase induction motor

    Is this an educational project or is it intended to be put into a functioning industrial setting (with associated H&S)? What are your budget limitations? Are you working with star or delta and do you want to measure phase current or load current? Do you want to measure any unbalanced current...
