    Microcontroller programming

    Hiya, I am working on a project, which includes a P87LPC767FD 8bit microcontroller.

    Capacitor voltage

    Thank you very much for your help. The pot, was simply to control the amount of electricity flowing into a chip so as to control the output. Anyway thank you very much for clearing that up for me. Diarmuid

    Capacitor voltage

    Hiya, I've just got what I hope is a quick question.

    transistor markings/replacment

    I dont think it is that one, as the one I have is in a case with one round side and one flat side.

    0 ohm resistors

    On an audio circuit I am copying, there are a lot of resistors with just one line, a black one in the centre.  As in the colour code, black is 0 are all these resistors likely to be 0 ohms and thus can I just replace them with normal wire? Thanks for your help Diarmuid

    transistor markings/replacment

    The case is pretty much the normal size, in that it is like all the other transistors  I have seen.  I dont know the exact sizes, but if you could tell me what measurments I need, I could probably find them. Thanks Diarmuid

    transistor markings/replacment

    Hi, I am having some difficulty duplicating a circuit which I have come across.  One of the components, is a transitor and is marked in the following way: 1) It has 205 M8 on the top 2) and 206 j174 on the face side I have tried running various combonations of the above markings through...

    Timed resistor

    From what I can find, 555 timers only seem to be able to output pulses, is this right, because I need a steady output as opposed to a pulsing one. Thanks very much

    Timed resistor

    I am building a small 10V control panel, for a stage lighting system at my local school. I have so far, got a working plan, of all of the desk apart from one bit, the fade timers.  I am looking for a chip, or poteniometer, so that, I can twist the potentiometer to full, then when a current is...

    Resistance and Resistivity

    yeah, I suppose it is. I'll try and get one today, from amazon. thanks Diarmuid

    Resistance and Resistivity

    Thanks for all your help so far. I am guessing that R, is resistance, but what do U and I stand for? Thanks very much Diarmuid

    Resistance and Resistivity

    Hi, I am looking for information, on how to calculate the resistance I need, for example If I had, the voltage I wanted to put in, and the voltage I wanted it to put out, how would I calculate the resistance needed? Thanks Diarmuid

    Audio Mixing Desk

    Thank you so much for all your help so far. The only transformer I can find that is above 150VA, is a 200VA one, the site mentioned that it would be possible to use a higher transformer, however it mentioned that the fuses and Caps would need raising to a higher limit.
