Instructables
Hi everybody,

this is my first piece of DieselPunk.  :-)

The clock shows the seconds, minutes and hours by industry mA meters.
It is drive by a DIY kit from a German company called ELV.
The CPU - Board inside controls a real time clock and get the time from a LW - time - transmitter near Frankfurt.

A switch switches the electronics off, a backup battery keeps the time in the real time clock.

Step 1: Parts

Picture of Parts
Assembling  the KIT is easy because the SMD parts are already soldered on the board.
All parts needed comes with the kit. Even additional trimmer to adjust nearly every type of mA Meter without shunt inside.

Step 2:

To build the case follow the instructions on the pictures below

I have some candidates from GOSSEN Mueller & Weigert for the meters:
9600000030B
9650000000B
9600000010B
What do you think about these voltmeters? These are bit cheaper that the recommended 9600600040B.

You can use nearly any type of moving coil meter without shunts etc.
The electronics is able to adjust a very wide range.

The maximum output voltage is 2,34V and the maximum current is 15mA approx.

Have a nice day,

Any better specification for the meters? I'd like to use big meters.

This is a very nice clock. Can you adjust the time if you are not in range of the radio station in Frankfurt? I am in the States.

Good morning,

as I know, there is a transmitter in the states as well.
But they have different signals and frequencies.
The clock has no manual adjustments :-(

Sorry to say no.

With kind regards,

Nice project my friend, it is a good thing to depart from the normal design and create a completely new look, I hate it when I'm posting a project and the program will not cooperate, but still it's good to see a idea from you, even if all the details of construction are not there.

I will write some more details. But the server wont let me save all the additions. If I try it it will say "permission denied" and everything is lost.
So I will write here:

The board is mounted with three screws on the back cover of the clock.
If you close the cover the board is inside the clock frame.

The meters are mounted with two tiny screws.
The Kit has a special mode where you can adjust the minimum and maximum of the pointers.

The battery is a 9V block battery and the power can be switched off by a switch to save power. Due to the backup battery the clock will hold the time an when you switch it back on it will do a new sync.

The case was made of MDF. The "coolings" on both ends where made of different sizes of MDF pieces just painted in silver (the bigger parts) and black.
This gives the expression, that the case will go trough the silver parts of the ends.

This is a really great project, but I think a bit more in the process description would be really helpful. A bit more explanation about how you made it, ie how you incorporated the ELV DIY kit into the clock frame, would make this guide!
