MILEAGE_COMPUTER

Published:2009/6/28 21:10:00 Author:May

Fuel consumption in miles per gallon is continuously updated on 2-dight LED display. Entire system using CMOS ICs can be built for Iess than $25 including as-flow sensor and speed sensor, sources for which are given in article along with operational details. Circuit uses rate multiplier to produce output pulse train whose frequency is proportional to product of the two inputs. Output rate is time-averaged. Speed sensor, mounted in series with speedometer cable, feeds speed data to CD4527 rate multiplier as clock input. Gas-flow sensor, mounted in series with fuel line, feeds clock input of other rate multiplier.-G. J. Summers, Miles/Gallon Measurement Made Easy with CMOS Rate Multipliers, EDN Magazine, Jan. 20, 1976,p 61-63.   (View)

MONITOR_POWER_SAVER_FOR_COMPUTERS

Published:2009/6/22 23:09:00 Author:May

The circuit monitors PC keyboard activity through five-pin DIN connector J1. When the user presses a key, the keyboard sends a series of negative-going pulses on pin 2. In conjunction with Q1 and C3, the op amp essentially functions as an integrator, which stretches the continually varying periods of the input pulses to a relatively constant period with a higher average dc value.Inverters IC1-c and IC1-b buffer the peak detector's output to trigger IC4, an MC14536B programmable timer.   (View)
