Hi, that is what audioguru tried to make clear to you. Yes that was my first attempt but it failed so hard I switched back to just one chip, but it still behaves very odd. Forums New posts Search forums.

The datasheet for National’s ordinary the LM shows that it needs two supply bypass capacitors to keep other ICs from crashing when the output switches. For a better experience, please enable JavaScript in your browser before proceeding. The problem is, I’ve got the timer to work, no problem there, can adjust the pulsing speed with a k potentiometer just mounted a LED to pin 3 with a ohm resistorno problems there.


Well I haven’t ground pin 11 indeed. If output current is close to maximum increase the value of C1 accordingly.

So well, the cascading comes for later. Replacement Transformer Started by ncag Today at 7: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at To participate you need to register. Can’t find any errors in my configuration.

Why don’t people read the datasheets??

The datasheet for the Cmos Intersil’s ICM shows that an ordinary causes a supply current spike of mA when its output switches. Plus, I don’t hc4f017 any problems with how my chip functions, that one just works fine imo.

Thread starter Smonjirez Start date Oct 6, Boncuk New Member Oct 9, The control pin has nothing to do with decoupling. Else I still have no idea what to do. If you don’t then the circuit probably will not work properly.

Your CD is not connected to 0V so it cannot do anything. You must log in or register to reply here. But, when I connect pin 3 from the timer to pin 14 from the chip and of course the 0V, reset and enable pins to the 0V linethe output is kinda weird. But if you’re talking about another condensator connected to another input or something, could you please modify my circuit and post it? I’m currently working on a knight rider scanner. But, it flashes totally randomly and in variating brightness also totally random.


You do have a resistor in series with the LED?
