Pythagoras 3D Model

I just finished the computer 3D modeling this new clock. The more I work in it the more I like it.

 Pitagoras Iso1

I bought the solenoid from Amazon and this is the link:


Here are some screen capture of the 3D model. Any comment and suggestion will be appreciated.

New Clock on the way

After a year of zero productivity due to health problem I was forced out of my garage and hobbies as I needed to recover my finances. Fortunately I am back to my professional activities that makes me travel a lot.

My heart and my mind are still with the clocks and I just finishing a new design.
My new clock, still in paper but very very advanced in the design has a name: Pythagoras and here is a pic of the basic drawing:


One of the big problems of the wooden clocks is the precision. They are really affected by temperature and humidity. My friends are always asking for nice clock and a the same time with precision. Wood, brass and gravity will never make a high precision clock although they are really pieces of  art that require a lot of dedication, love and tons of patience but common people do not understand this. When I show my clocks the first thing most people say is “How beautiful!.. etc, etc. But a second later the big question: How precise is it?

So I decided to mix electronics and art and create a Microprocessor controlled wooden d clock. This clock will be driven by a Solenoid that will tick each 2 seconds    The Escape wheel is a ratchet with 30 teeth. The solenoid has a total movement of 4 mm that will be converted in a 12 degree rotation of the wheel. The other design characteristic is that the distance between centers of all the wheels is 2” and the position of the wheels forms almost a triangle rectangle. This is the reason for the  Pythagoras name of the clock.

As usual I will start with a test stand for the driving mechanism: The escape wheel, the solenoid and the microprocessor, and I will be sharing with you all the leanings. As I am traveling a lot for working reason this will be slow, but you can be sure that I will finish this clock.

See you soon!
