RETRO STYLE CLOCK - PRINTED PLATE

Producer: AVT

Nowadays, programmable systems displace discrete digital circuits. Finding a clock design without a microcontroller seems to be very difficult, and yet not so long ago only electronic clocks were built in this way. Yes, these types of devices are complicated and can take a lot of electricity, but it's hard to deny their basic advantage - they work immediately after turning on the power. They do not require knowledge of any programming language but only a few elements of combinatorics.

Recommendations: we mainly recommend people who want to take a break from ubiquitous programming.

Basic information:

• power supply from the 230 Vac power grid
• measuring time in a 12-hour or 24-hour system
• adapted to supply from 50 or 60 Hz networks
• no quartz generator - the basis of time is the mains frequency
• without microcontroller and other programmable systems
• a printed circuit board and documentation in the set

Attention! When starting up the system, special care should be taken because of the dangerous tensions present in life. If you have no experience or are afraid, ask someone who is familiar with it. Never lift, do not twist, do not touch the plate if it is connected to the mains!
If you make any changes to the layout, remove the plug from the socket!
