No i live in the UK But thanks for your help :) I might change the 555 circuit to a latching circuit, it should work with what I am making

Is there any possible way of using the one i have?

The other Relay is about the same as the first relay I don't think i will be able to get the other transistor, but why can i not connect the relay from pin 3 to ground? I worked once before but for some reason i couldn't get it to work

Sorry the relay was 65.2 The transistor has a hFE of 563 on the transistor it says BC548 and underneath it says -G21 ( i think ) I do have another relay

I didn't use a resistor, and yes i tested my transistor and it came up as 500 something, not too sure cause i didnt note it down

I have just done the transistor circuit but it doesn't work

Yes that was with no load On the 200 ohms part of my multimeter thing it says the resistance is 6.52 My power supply is 9V, but i measured it with no load and it was 15v (DC), would that blow the chip? With the circuit that included the transistor, is the resistor coming from the chip...

Hi again, I've done the thing with the diode, but i don't think a 9v battery is enough volts for the circuit? The Volts coming out of the battery is about 8.20 The Volts going to the coil when the button is not pressed is about 2.40 The volts going to the coil when the button has been...

Ok, ill get a diode tomorrow and a new 555. I think it turned back on because the battery was running low

When i turn on the 555 circuit and the motor circuit it works , but if i leave it in the off state it comes back on after a while. Will putting the diode across it solve this? (I measured my plug and it was 15v)

Can an LED be used as a diode because i don't have any diodes at this minute :P

Thankkss for that, i understand now :P I have started from just the 555 circuit and it seems to be ok, but i think it randomly turned on earlier, but i think some of the contacts touched. Thanks for your help :D

Sorry that went straight over my head :rolleyes: The relay says: Res. Load 10A 240VAC or 24VOC Coil DC 6V Im not going to use the plug on second thoughts. Im also confused at why the relay does not work from pin 3 to - because it worked once, but then i re made the circuit and i can't...

This is part of the circuit. The other part is completely separate so we won't worry about that. I changed the capacitor and it worked fine, but now its going funny again. I don't know if it is bad soldering but i have checked the joints and they look ok to me. Thanks

Just another monostable 555 timer question :D I have a 555 monostable circuit with a relay attached to + and pin 3. I tried attaching it to pin 3 and - but it didn't work. Anyway, its very temperamental and keeps going that when you push the button it will stay on for about 2 seconds or less...
