Build your own working Talking Clock! It looks exactly like an ordinary analog clock, but it also announces the time with a voice at the press of a button. The arm movement is driven by the speech circutt, thereby synchronizing the analog time and the digital time. This can be used as a alarm clock, or with hourly time announcement. Learn about gears and how time is kept electronically. For ages 12 and up, with adult supervision. Contains small parts; not suitable for young children. |
