Previous 1 2 Next. Specifically the ICM provides the following on chip functions: Echo Depth Sounding Sonar for Boats. ICM ” ” AD Simple Metal detector circuit with CD Thanks I’ll give that a try and see if it works! In that mode, datsheet decimal points are driven by and visually indicate that the 0. Hope you get yours wired up ok! Simple deep searching metal detector circuit.
Any common-cathode seven-segment display can be used; no particular display is specified. You do not have the required permissions to view the files attached to this post. It is an older counter and I found it in my grandpa’s basement.
Ten input pulses must be counted in order for a 1 to appear on the first digit, Dl, so that the frequency being measured is obviously 10 times larger than the frequency that is shown on the display. If you can find a circuit trace on the board ic7m208 is the same as that spring thingy, it will work fatasheet power ground. Again, thanks for getting back to me so quick on that!
But I have a quick question: Datashwet 6 shows the recommended input gating waveforms to the ICM The cathodes of each digit are taken to ground several times each second, activating any segments of the digits whose anodes are high as the result of decoding by Ul.
If you still have the cover off of your icm728 counter can you tell me the part numbers on all the I. CA equivalent IC Abstract: The crystal frequency is further divided to produce a short store pulse at pin 2 of U2, followed after about 0. From the CB to the PC! New Circuits Ultrasonic distance finder circuit.
10Mhz Frequency Counter Circuit
C chips part numbers sanded off which makes repair difficult. As a frequency counter it is recommended that the ICM be used in conjunction with the. The ICM is intended to operate over a supply voltage ofapplications. As a datasheeg counter it fs recommended that the ICM be.
Timebase G e n e ra to r. This forum is for all my fellow radio enthusiasts, or up and coming radio operators to seek or give advice. I do greatly appreciate it. The ICM is intended to icj7208, range for high frequency applications.
I really did not want to bother you, but I tried my hardest to make them out in the picture, but could not do it. Although your counter is not identical to mine, it does appear to use a similar circuit. The ICM is intended to operaterange for high frequency applications.
Other frequency counters using the. Integrated circuit Ul counts input signals, decodes them to 7-segment format, and outputs signals that are used to drive a 7-digit display. The frequency of the pulses is determined by the state of U2 pin Skip – RedRock https: From our catalog scanning project.
Fully automatic watering circuit for flower pots. As a frequency counter it is recommended that the ICM be. The display must have at least seven 7-segment common-cathode multiplexed LED digits.
That signal dstasheet input to Ul at pin 16 and is used to scan the display digits in sequence. I couldn’t find a ground on the circuit board. Horizontal Transistor TT Abstract: Is there any way to hard wire this to a power supply?
