RTC

A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. RTCs often have an alternate source of power, so they can continue to keep time while the primary source of power is off or unavailable. This alternate source of power is normally a lithium battery in older systems, but some newer systems use a supercapacitor, because they are rechargeable and can be soldered. The alternate power source can also supply power to battery backed RAM.

Chiming Clock

“An update of a previous big ben digital chiming clock, with an Android bluetooth app to adjust the time and set the date on boot up. This is a variation of a previous Chiming Clock project. By using an ESP32 …

Dual Spiral Marble Clock

“This is another one of my clock projects this time inspired by marble clocks. However, not wanting to replicate an existing design I created my own. Where most marble clocks contain a large number of marbles, this design is minimalist …
