MINI-TOWER WITH ACOUSTIC SIGNAL - A KIT FOR INDEPENDENT INSTALLATION
Producer: AVT

This simple layout can be used as a portable kitchen timer, darkroom photographic chemical lab, etc. It was designed based on the extremely popular binary counter from the 4060 series C-MOS series. It contains in its structure a generator and frequency divider, so to operate minimum elements are required. The delay time is set smoothly by a rotary potentiometer. The system audibly signals the end of the set interval.

The device is especially recommended in situations requiring timing

Selected parameters:

  • the ability to adjust the delay in the range 1-20min
  • signaling status - LED
  • smooth adjustment of the delay time
  • signaling of measured time - sound
  • built-in piezo transducer with generator
  • power supply - 9 Vdc (battery)
  • plate dimensions 30x54mm
  • in the set a printed circuit board, a set of elements and documentation
