Increasing them will minimize overall power consumption and make the transformer run cooler. Askar Alibolandi 29 Jun Reply. Press switch S6 2. Two diode D1, D2 are the switch signal generators to the cathode of display number for working alternately and relation l8560 the input of IC1.

The chip’s absolute maximum power dissipation is mW. During testing I noticed the display was lm85660 dim suggesting an unusual current load or other malfunction, plus the alarm was not functional.

LM , Tube LM; R̦hre LM ID, IC РIntegrated

Diodeman 2 Jan Reply. Hi, John You can find at amazon.

Might be due to voltage drop. But they are fantastic clocks.


Digital clock alarm based on the Lm8560

They are no longer sold and GE has no support for them anymore. The digital clock circuit that electronic amateurs are most interested. Figure 3 The components layout of this projects. Leave a Reply Cancel reply.

Many electronics circuits and projects for learning in simple ways. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. To set the time turn on- off the Electric appliance. These are great clocks and if my lamp had not damaged it, it may have kept running lm856.

Some other details The chip can work with both 50 Hz this is what I used or 60 Hz mains frequency. To extended for another nine minutes, with the press of a switch S7. Cheap Digital time clock with alarm circuit. Parts soldered on the board.

This project is easier than one: While the power is out, screen output will also be off. The power supplied for each of the display segments is 18 mA.

The output to control electrical appliances with automatic timer. Can you send me a copy of the PCB layout?

LM Datasheet pdf – Digital Alarm Clock – SANYO

Hey please send me the original pcb layout file i want to build the clock like yours. When the time limit, the alarm signal will ring. I have a small lamp plugged into the same circuit.


It was impossible to restore functionality of the custom chip-onboard, but lucky for me the data sheets for the LM clock chip revealed that it could directly output a standard alarm beeping sound to a speaker. You just connect the 9 volt battery, by the negative terminal join to diode 1N into pin 20 of IC1 and the positive terminal at pin The schematic Since I lj8560 in need of a easy to read clock, I decided to make one with this chip.

Putting it all together First the PCB was built using the photo-transfer method then etched. I was lucky to find one in one of the scrap boxes. It lm850 be too hard to use normal leds instead of a display. The clock will need mains voltage for operation, battery operation is not supported see pt. The one in the picture was cut from a broken floppy disk ribbon cable.
