Remote-Controlled Clock DIY Soldering Kit

The BCL-1 Remote-Controlled Clock DIY Soldering Kit offers an exciting hands-on experience for makers and electronics enthusiasts. This kit allows you to build a fully functional, remote-controlled clock with precise timekeeping and various practical features. Whether you’re looking to develop your soldering skills or create a useful home device, this kit provides both learning and functionality.

Parameters

Model: BCL-1
Operating Voltage: 5V (USB-powered)
Remote Control Size: 86mm x 40mm x 6mm
Light Shell Diameter: 60mm

Both the clock and remote control come as components that require soldering and assembly. The remote control is a plug-in version, making it easier to assemble.

Function

• Hourly Chime

  • Chimes on the hour from 7:00 to 22:00 (can be turned off if needed).
  • Individual alarms can be enabled or disabled, with a shortcut key to quickly turn the master alarm switch on or off.

• Error Correction

  • Adjusts timekeeping with a software-based correction feature. After manually enabling the correction function, set the parameters X and Y.
    • Y > 0: Adds Y seconds every X days.
    • Y < 0: Subtracts Y seconds every X days.

• Power-Outage Memory

  • Equipped with a clock-specific chip and backup battery. Even when the external 5V power is disconnected, the clock continues to keep time using the backup battery, eliminating the need for recalibration after power outages.

• Accurate Timekeeping

  • The clock uses a crystal oscillator with a precision of ±5 PPM to ensure reliable timekeeping.
  • Combined with the error correction feature, the monthly error can be controlled within 30 seconds.
