    To get the smaller size in KB you have to reduce the size in inches. Another alternative is to try to get it into a greyscale format. But then the pixels are not as tight and you loose the detail. I think the sise limit is a big bother and it limits what you can post.

    How do I make a dc circuit auto-off after 60 minutes

    Try my timer it works well on 9vdc too! Use a Larger capacitor like 2200uF to 4700uf and experiment with it. It is a delayed off timer. When you push the switch it turns on the load and turns it off after the timming cycle. off. If the switch is pushed again durring the timing cycle it resets...

    You have to be patient and Persistant. I have a way of searching that seams to work. I use alternate Key words and Terms to find what I want. It also takes hours of time looking for one datasheet. As you see There are alot of them I can not find. After 2 or 3 days of searching I put it aside for...

    Here is what happens when you size it down. And convert it to GIF Is it worth Posting like this? I don't think so! So stop complaining over pictures being too big for the browser or we could all suffer from the poor quality of the picture from it being so small that it is not ledgable or usable.

    So what if the picture is big. Some of us older people can't see small pictures anyways. Plus you can read the values better and see the details better.

    I Did make the pictures smaller then they were worthless because you couldn't read the values and some of the lines were missing because of the size. Most datasheets are bigger than that! I have all of these in a pdf file but it will not let me upload it. I thing PDF files should have a bigger...

    water pump

    Use bigger wire going to the pump. Too Small of size wire causes a line Voltage drop and the Motor will draw too much Current .
