![]() ![]() The heart of the electronics for this clock is a Texas Instruments MSP430 microcontroller. A hardware kit of all the non-wood parts, including the electronics, is also available at. (Sorry Carvewright uses a proprietary file format no files are available for other CNC machines). Here is a video on the design and construction of the clock: Synchronicityįiles are available to machine the wood parts of this clock on a Carvewright CNC. My circuit is powered by 4 D cells, which will operate the clock for up to three months. I wanted my clock to be accurate, so I use a microcontroller in my electromagnetic pendulum drive so that the clock keeps perfect time. Wood expands and contracts with changes in temperature and humidity. Often times wood clocks of this type are not very accurate. This triggers electronics to put a pulse of current into the coil (or a second coil) and repel the magnet, giving the pendulum a push and powering the clock. As the magnet passes the coil, it induces a current in the coil. The pendulum contains a rare earth magnet which passes by a coil or two. Some designers use an electromagnetic pendulum to drive their clocks. ![]() ![]() I wanted to build a wood gear clock that did not require that frequent winding. These clocks need to be wound periodically, as often as every day. Many wood gear clocks are driven by weights. Synchronicity is a unique exposed wood gear pendulum wall clock, with a combination of old and new tech. ![]()
