DIY Clock Kit "C51 YSZ-4"

Too bad that the kit is delivered without housing and power supply. Otherwise, it is a good entry-level soldering set and you will surely keep the working clock in your hands after 1 hour.

You can find videos and different PCB versions on the net. My kit consisted of 17 components and has the modest name "C1 clock YSZ-4".

There are different PCB versions in circulation.

Download here the manual for more information. There are 2 alarm-clocks available.

A prepared resistor block with 9 PINs is the "PR1".

The back shows the soldered components and the ends to be shortened with the pliers.

If you do not dare to assemble and solder this DIY kit please contact me via PM.

Update 10.05.2019 - Case

In the attachment you will find a STL-File for a 3D Printer to get a case.

I soldered the terminal adapter on the back instead of the intended one and planned a 2x AA battery compartment.

Update 15.05.2019 - Case v2

Improvement of the back with a 3 mm reinforcement and a pilot hole for M3 screws.
