All slaves can be advanced or retarded from the master clock.

Also 2 large 12" dial clocks with 30 sec and 1 sec syncronized movements. 1 sec quartz clock driver diagram also included.

The clock now chimes via a 4" longcase clock bell and 30sec clock movement(see pic).

Hi Brett

I noticed from you updated web site that you used a small relay with a bell hammer attached for the bell strike.what sort of relay did you use and did it prove worth while?

Hi Mark it is not really a relay. It's a 30sec clock motor with the gears stripped out.

Hi Brett

Realise that you made a bell ringer form a slave clock movement but also along side that from your website is another option using a relay or am I confused

I'm just making one of my own but I ended up using a converted post office type relay (3000) Just thought yours with a miniature relay would be more compact!!!

Just wondered what type of relay it was and if it performs ok!!!

Hi Mark
The relay is just a small 5v relay (can't remember which one) that had a large armature so I could attach the wire to strike the old telephone bell.

This option is very compact and sounds nice but is not very loud. In the end I went for the large 4" bell and slave movement that can be heared all round the house. If you have more than 5volts to play with then you will have more of a choice of relays.

Your PO type relay sounds a good option though.

Thanks heaps for sharing this project, and putting such good documentation up for it.

I don't care at all that some might consider it too hard, or complex, that what's makes it so appealing in my book, I think this is an ideal application for a "Steampunk" design clock!

Has certainly got me thinking, and I really like the binary clock.

Kudos to you Oliverb!
