i think this is the place to put it. i am looking in a dc (15v) relay. i want to have it so i press a butten and it opens for 5 or so seconts. i cant find how to do this so does any one know how i may go about doing this. thanks

Thanks. looked at the site Looks just like i need (since i have 2 extra power supplys). I have a question. where can i find a graphite rod? i heard somewhere that 9v batterys have it but where would you think

I have wondered how this product works forever.it is this little packet that you can buy at REI. it is a clear liquid with a metle disk in it. when you slap the disk it heats up and turns into a solid. then you can boil it and it can be reused. it contanes sodium acetate (food grade [if that helps ]) and water. i asked all my science teachers and well nothing. any idias

ok i can guess that this will be answered in a few seconts . But for years i have tryed electrolysis with water but all i ot was little bubbles. i think it is the source i use. i use a 9 V battery. What voltage and amprage should be ok to get max h2 and o2 production. Thx
