We’ve seen a great many cat feeders over the years. Some rely on the Internet of Things, and some rely on fancy microcontrollers. [Larry Cook], on the other hand, built his using a simple 4060 binary ...

Logic Noise is all about using analog circuits to make sounds. Preferably sound that will be enjoyable to hear and useful for making music. Now, the difference between music, sound, and noise is ...

The 74HC/HCT161 are presettable synchronous 4-bit binary counters with asynchronous reset. These devices are high speed silicon-gate CMOS devices that are pin compatible with low power Schottky TTL ...

The HEF4020B is a 14-stage binary counter. This device contains a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (Q0, and Q3 to Q13). It ...
