Six-way blinking light string circuit ( 1 ) ( HFC3018 )

Published:2012/12/4 20:55:00 Author:Ecco | Keyword: Six-way, blinking light string

The circuit uses 5-way flash signal output by HFC3018 to drive solid state relays SSR1 ~ SSR5 and make them sequentially turn on and off, which enables the lantern strings E1 ~ E5 to be extinguished in a turn. Manifold output analog sound signal can drive solid state relay SSR6, which make the the six groups of lantern chain E6 flash with analog sound storaged in manifold, pressing the button switch SB one time can obtain a flashing mode. HFC3018 has eight kinds of analog sound, it can produce eight different flashing effects.   (View)

Voice lamp circuit diagram

Published:2012/12/4 21:20:00 Author:Ecco | Keyword: Voice lamp

The circuit uses a six-gate IC CD4069, and its Gate 1, Gate 2, 3, and R1, R2, R3 form a three-level signal amplifier. Once people click on a Palm, applause is picked up by electret microphone MIC, and its sensitivity is adjusted by RP and amplified by subsequent three-level amplifier, then detected by C5, D5, D6, C6 to get DC control voltage, this voltage is inverted by gate 4 to control the flip of subsequent bistable circuit.   (View)
