Alarm clock in bedroom

Observations and conclusion

There are couple of observations after a month use of this product on my list. Fortunately, no serious issues. I will modify it some day.

  • LCD misses continuous backlight intensity control. When your eyes are adopted to low light condition, you must wink when the LCD turns on.
  • I miss ambient light sensor in order to control maximum backlight/LCD intensity.
  • I would add two USB connectors at the shelf top in order to connect USB cable for mobile phone for charging.
  • I miss some software lock for time setting section. My kids find this product to be a very good toy and set up everything they can.

If there is someone interested to see costs, I can add some info on this.
