Btw, I’m using a 12 – 13,5v accumulator as a powersource. Thread starter Smonjirez Start date Oct 6, This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

But if you’re talking about another condensator connected to another input or something, could you please modify my circuit and post it? For a better experience, please enable JavaScript in your browser before proceeding.

Smonjirez New Member Oct 9, The datasheet for the Cmos Intersil’s ICM shows that an ordinary causes a supply current spike of hcf40177 when its output switches. Else I still have no idea what to do. Forums New posts Search forums. The circuit will work alright if you cascade the counters. If you don’t then the circuit probably will not work properly.

Datasheets, Manuals or Parts. But, it flashes totally randomly and in variating brightness also totally random. 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.

Hi, that is what audioguru tried to make clear to you. Boncuk New Member Oct 9, You do have a resistor in series with the LED? Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Media New media New comments Search media.

The control pin has nothing to do with decoupling. 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.

So well, the cascading comes for later. I think you are talking about the 0,1uF capacitor which should be connected to pin 5 control? How much current are you trying to draw from the pin? The datasheet for the LM says to use a 0.

This stays the same when I mount more LEDs to the other ports, it’s not how it’s supposed to be. Got part of the scheme from internet Knight Rider lights for model cars and extended it myself with another additional chip to use 8 LEDs in this “back and forth” configuration. But, when I connect pin 3 datadheet 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.

Smonjirez Datashfet Member Oct 6, I think this is what you want? Yes that was my first attempt but it failed so hard I switched back to just one chip, but it still behaves very odd. Boncuk New Member Oct 6, Replacement Transformer Started by ncag Today at 7: Articles Top Articles Search resources.
