need help on 555 110v timer.
hey guys w up?
i`m asking for help, i`m trying to develop (i have one, similar) a 110 v timer based on the 555 (or any other) i have seen many timers on the web but they run on 9v batt and i do not have room for the transformer , can u help me ??? all (just nothing) all i need is the electronic diagram .
i need the timer to work on 110v and run two different cycles
a: 90 seconds
b: 180 seconds
and cut the power. (untill you press the push button again)
i have an electric diagram.
tx so much.
if you need help w something (i`ll try to help you if i can) even if you can`t help me ..ask e have nothing to loose.

hey your request got me to sign up. Looks like you last check on it in Aug so maybe I'm too late. I can't tell if you have built many electronic circuits before so if I suggest something basic don't take it the wrong way. First off - 110v (assume the main house power) can be dangerous - fire, shock etc. the 555 circuit will need to run on a small dc voltage, get a datasheet on it if you have not already. suggest using a small battery for the 555 part and a relay to open and close the heavy power. Also, I bought a device (think it was $15-20) to remotely control the outside lights. It wireless controls any 110 device. It's made by dimang. hope this helps

i´m really sorry to take this long to answer ... long story short... was ill... now better ... lol i had the diagram for one circuit running at 110v... i lost it... i know a little about electronics but not enough to make my own circuits... im re taking the proyect... tx for the help!! and once again ...sorry.
