You could use one of these, set it for the start time, and use the output to control a v relay which would operate the washer button.

I’ll be really very grateful. There datwsheet problems with timer approach. Set the off time on the timer as close to the start time to release the relay.

Have a look at basing 74l1s62 circuit around a CMOS stage ripple counter and oscillator. Hitachi bears no responsibility for failure or damage when used. I know you specifically said that you did not want to use a microcontroller, but I think you should consider taking the plunge into the microcontroller world.

The resistors and capacitors use to set the frequency are not all that accurate, and they drift with temperature. Will be grateful for any 774ls162 I thought about using capacitor and coil to make my own oscillator.

This product is not designed to be radiation resistant. There are lots of timers that are used to turn lights on and off 74ls62 they have a switched v outlet in the US.

Yah, I know, it’s kinda funny. General directions for a timer circuit which will not use microcontroller and which can measure several hours needed Ask Question.

Copyright ‘ Hitachi, Ltd. I have used these in the past for long interval timer projects – before PICs came along: I’m thinking that the button could be replaced by a transistor or some sort of normally off relay. It looks promising to me. Some background info first: Products conform to specifications per the terms of Texas Instruments standard warranty.

Actually I 74lss162 would have thought of finding a useful purpose for my stack of alarm clocks which I never used. Post as a guest Name.

In my country, price of electricity depends among other things on the time of the day when energy is used. CMOS timers can be used to achieve delays of hours. I know that a book can be written for every point, but at this moment I’m just looking for some rough ideas.

I think the best solution is to use CD with a crystal oscillator which can produced 1Hz pulses. How would 74ls12 design a circuit which would wait for several hours and then “push” a button without using microcontrollers? I’ll take it into consideration. At least it will work in the presence of a Tesla coil while being tapped by a hammer or the washer’s spin cycle.

In general I have found that using a “complex” circuit of discrete components is usually plagued with minor errors in both design and construction that cause them to take a lot of time and money. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

Email Required, but never shown. I know that a microcontroller is the most elegant solution, but I’d rather skip collecting necessary gear for working with them at this time.

Then use a counter datasheeet the 1Hz pulses as clk and use it to count the seconds.

IT takes v AC as an input and provides a 24v DC output for driving relays or switch lights in this case. Ecoflair Technical Specifications Provides detailed information on unit While it definitely wouldn’t be 74ks162 educational as making a circuit from scratch, it would quickly solve my problem.
