Dec 25, 1. Dec 22, 5 0. I am building a circuit with a counter that I’d like to have a 60 minute cycle.

4060 timer calculation

How do I calculate the resistor and capacitor values I need at pins 9, 10, and 11? I know the resistors at pin 10 and the capacitor at 9 determine the oscillation, but what does the resistor at 11 do, and what are the ideal ranges for each of these? Dec 25, 2. Aug 23, 6, The below is 1Hz crystal oscillator, it is linking from my blog. Dec 25, 3. Nov 12, 3, 2, Dec 25, 4. Oct 2, 5, 1, Dec 26, 5. Dec 26, 6.

Nov 4, Dec 26, 9. Here is the RC oscillator right off the data sheet: Dec 27, Mar 24, 21, 2, I’ve designed quite a few and circuits.

I usually use a to drive a relay for power applications, but this is not always needed. You also need to think about accuracy, you can do this with one and a RC clock setup part of the or with a crystal oscillator, your choice.

A crystal can be used in a digital clock A with a watch crystal can make a very accurate 2Hz signal, which you would then drive a second circuit with. A RC can use just one chip plus the timer. Nov 30, 18, 9, I did this with an LS Very similar to a chip, but allows for programming both time constants on time and off time.

The difference in this case is the frequency. With the RC the oscillator is at about 4.

With a crystal about the lowest frequency available for a small cost is You don’t need a to turn on the LED or other device with the Depending upon the current required a transistor will work fine. Side note, I am assuming a So you would probably need a second if you chose to go the crystal method. Apr 9, I bought that chip from Radio Shack, long before I knew about this site or online vendors.


Somewhere in the ‘s IIRC. The point is, it was convenient to get this chip at that time. That’s probably the major reason I used it.

Robotic Floor Cleaner Robotic floor cleaners have been available as consumer products for a number of years now but with a gradual drop in production cost and development of new technology, these cleaners are becoming cheaper. In this teardown we will look at a Robotic Floor Cleaner which uses “electrostatic forces” to remove dust and can clean a room with its “intelligent” obstacle navigation.
