    Digital Counter

    It sounds as if you are looking for combinations of modulo counters, which you want to construct. Here is a link that might help you: http://www.colorado.edu/physics/phys3330/PDF/Experiment10.pdf My personal method would be to use a microcontroller. One chip would do it all and more. MP

    transistor help

    daron, are you looking for a schematic of a transistor circuit that will blink an LED or are you looking for a cross reference for the transistor you mentioned? If you are looking for a cross reference for the transistor, you will have better results in the data sheet request forum of this...

    Digital Counter

    where are these numbers going? are they pulses? are they displayed on a LED displayed on a LCD? tones? MP

    Question on the Plants Watering Watcher circuit

    Here is what you said: The author recently told me that he may update his circuit with my improvements when he has time in a couple of months. But it would seem in your last post that he only agreed to try the circuit with your changes in a couple of months. This is a little different than...

    Light Switch

    Siddharth, I just checked the regulator on the bench. As I said, the above voltages were verified. I do not recall which path you went from the original design. Can you post your fnal circuit? MP

    Question on the Plants Watering Watcher circuit

    That is quite a boast. You suggested changes but did you even heat a solder iron on one of them? It is easy to suggest changes to a circuit and still have it work. I have seen no confirmation that you fixed anything on this site. However, I have seen you boast that you taught Phillips...

    Question on the Plants Watering Watcher circuit

    Very true my friend. Theory is only a starting point. If I made the dimmer switch myself, I would not be so quick to ask the manufacturer to redesign the switch, and especially when others have claimed it works. MP

    Question on the Plants Watering Watcher circuit

    All you are suggesting is another circuit. Yes, a pseudo form of PWM is being used here from the cancelling operation of the two gates. The duty cycle causes the dimming effect. When the circuit has a history of working, and you suggest to replace the main IC and several other components of the...

    Weird relay problem..

    Kasamiko, A line voltage drop down to 185 VAC drops the 12 VDC buss to a level too low to switch the relay? MP

    Question on the Plants Watering Watcher circuit

    The LED brightness is controlled by the differential between the gate circuits. Not a gate action directly turning on the LED. But, whatever. Believe what you want. ::) MP

    Weird relay problem..

    audioguru, you can argue the point all you want, but what I have offered is a module which is time proven. Not theory. Rhonn can take it or leave it and it would not move me in any way. Suggestions from others seem to annoy you. Or perhaps just suggestions from me ;D. Still annoyed about...

    Question on the Plants Watering Watcher circuit

    audioguru, the circuit is a comparison of 2 square waves. A square wave coupled through the resistance of the probes and the untouched inverse signal. The difference gives you the dimming of the LED. It is not a single pulse which turns on the LED. Nor is it a gated action which turns on the...

    Weird relay problem..

    audioguru, 1. I have not reversed my terms. I was refering to what he is doing to the base or in other words, what his 555 circuit will be doing to cause the relay action. Not a reference to what the transistor is doing to the relay. This is a proper use of the term. By your own definition, the...
