It shouldn’t be too hard to use normal leds instead of a display. Hi, This looks really interesting. Julius 15 Jul Reply.
Cheap Digital time clock with alarm circuit. One disadvantage of this design is that the clock will only be as accurate as these oscillations are close to the rated value.
Two diode D1, D2 are the switch signal generators to the cathode of display number for working alternately and relation with the input of IC1. The P1 so is fine a alarm sound pressure as you want. Please suggest what can be done in this scenario.
KH 19 Nov Reply. This will prevent oxidation of the copper. But it will not display on the screen. I started out trying to simply fix some broken hardware mounts that hold the display and button mechanism within the alarm clock that looks like the Scooby-Doo Mystery Van.
You can also go with a 2 x 7. Ajoy kumar sinha 2 Dec Reply. Can i know where to buy duplex display in malaysia. Chin 9 Nov Reply.
Digital clock alarm based on the Lm8560

Some other details The chip can work with both 50 Hz this is what I used or 60 Hz mains frequency.
Without the backup battery, the time will simply reset. This is not much of a problem today, but back in the day especially in eastern Europethe mains had probably around Hz so lm85560 engineers either avoided using this IC or made separate oscillator blocks with quartz crystals search for 50 Hz timebase circuit.
Sujjwal 21 Jun Reply. But they are fantastic clocks. That lasted a few days until the error code came back. This project is easier than one: Press switch S2 or other switches to stop the alarm sound. Many electronics circuits and projects for learning in simple ways.
LM – Digital alarm Clock – DIP
I was lucky to find one in one of the scrap boxes. The schematic Since I was in need of a easy to read clock, I decided to make one with this chip.
Swapan kumar Dey 9 Mar Reply. I used a 2 x 6V one, rated at mA so lmm8560 doesn’t get too hot. The maximum input voltage for the chip is V so make sure to use a suitable transformer.

One of the coolest features of the alarm was that it made a car honking noise when the alarm was activated. Samad Bond 3 Jun Reply.
Figure 3 The components layout of this projects. Each of those resistors is responsible for limiting the current on the 2 cathodes.
