The 6-Bit Digital Circuit Clock DIY Electronic Clock Teaching Kit is a 24-hour digital clock kit designed for educational and hands-on learning. It utilizes a combination of ICs, including CD4518, CD4511, CD4081, CD4013, and CD4060, to create a purely digital circuit without a microcontroller, meaning no programming is required. The kit features a second signal generator, counter, decoding display, and time calibration circuit, with a 1Hz square wave signal generated through precise frequency division of a high-frequency signal for accurate timekeeping, using a 32.768kHz crystal oscillator. It displays hours, minutes, and seconds on six 0.56-inch red 7-segment BCD (Binary-Coded Decimal) displays, with calibration buttons for setting time but no alarm function. The kit requires assembly and soldering, comprising components like a PCB board, resistors (470 ohm, 1K, 2.2K, 100K, 10M), capacitors (103 monolithic, 30P porcelain chip, 25V 100µF), diodes (1N4148), a 6x6x5 keypad, a 12D07 toggle switch, and IC blocks (16P and 14P). The assembled clock measures approximately 100mm x 55mm x 12mm and operates on a 5V power supply via a KF301-2P terminal.

Key Features:

  • Display: Six 0.56-inch red 7-segment BCD displays – Shows hours, minutes, and seconds in a 24-hour format.
  • Timekeeping: Uses a 1Hz square wave signal from a 32.768kHz crystal oscillator – Achieves an accuracy with an error range of ±1 second per 24 hours.
  • ICs Used: CD4518, CD4511, CD4081, CD4013, CD4060 – Purely digital circuit, no microcontroller or programming required.
  • Power Supply: 5V DC via KF301-2P terminal – Compatible with standard USB power sources.
  • Dimensions: Approximately 100mm x 55mm x 12mm (assembled) – Compact for desktop use.
  • Assembly: Requires soldering – Includes all components, such as resistors, capacitors, diodes, and ICs, for hands-on learning.
  • Operating Temperature: Suitable for -20°C to +85°C environments (based on typical component ratings).

Common Applications:

  • Educational Training: Teaches digital circuit theory, frequency division, and oscillation principles through practical assembly.
  • Soldering Practice: Provides over 50 soldering points, enhancing skills for beginners and intermediate learners.
  • Electronics Learning: Demonstrates the function of counters, decoders, and signal generators in timekeeping.
  • DIY Hobby: Allows enthusiasts to build a functional 24-hour digital clock for personal use or display.
  • STEM Projects: Suitable for school science fairs or electronics workshops, fostering an understanding of circuit design.

Considerations:

The PCB is labeled for component placement, but assembly requires basic soldering skills and careful attention to polarity, as errors can lead to malfunction. The claimed accuracy of ±1 second per 24 hours assumes proper soldering and component quality, but some users report slight drift over time, which may require periodic recalibration. The kit does not support time memory after power loss, so time must be reset each time it is powered on.
