SundialNow you can tell the "chime" of day with the electronic equivalent of the traditional sundial! The Sundial detects a moving shadow, plays the Westminster (Big Ben) chimes, followed by the relevant number of "pips" and finishing off with an appropriate musical ditty! Great for the summer garden. PIC16x84 powered, free source code available from our FTP site.

Alan
Dower Blumlein- an unsung genius who greatly influenced the development of 20th century electronics, A.D. Blumlein either originated or made profound contributions to telephony, monaural and stereo recording, television, radar, amplifier technology and signal processing circuits. He held 128 patents. Working originally for STC and then for EMI, he pioneered many ground-breaking achievements in audio, TV and wartime radar. He was as inventive and indefatigable as Thomas Edison, and this special EPE article pays tribute to Blumlein's pioneering impact in many fields of electronics.
