YES! i would be so thankful!I dont know where it would be on the internet
but I can draw this circuit myself, if u want me to!
But I havent ever used a real relay before, so I almost could do it, not quite.
But havent already made the circuit yourself - why do you need it?
I would love to help with that, But I actually came up with it myself, there is no link to it.hi dragon! can you send a link to this: amped discharge style oscillator
Don't think so......schematic you show relies on one transistor removing bias from the other.just replace the transistors with relays should be fine.)
Then stop offering a servbice you can't provide.But I haven't ever used a real relay before, so I almost could do it, not quite.
Not your first time.I didn't read properly
Definitely not. That is BS... The transistors do the switching.(just replace the transistors with relays should be fine.)
That video is imho next to useless. No circuit diagram given. Blinking circuits can be found by the dozen on the internet. Please describe what you want to do, then I'm sure we can find a simple solution.anyone willing to point me to a circuit for this relay polarity switching:
While possible with a relay, this is a bad option. A typical general purpose relay has an endurance on the order of 2 × 106 switching cycles (see e.g. this datasheet).the circuit must be able to switch battery polarities at 1-20 times per second
Thank you Harald for your help!While possible with a relay, this is a bad option. A typical general purpose relay has an endurance on the order of 2 × 106 switching cycles (see e.g. this datasheet).
[math] 2 × 10^6 cycles / /frac{20 cycles}{second} = 10^5 seconds \equiv 27.8 hours[/math]You'd be replacing relays on an almost daily basis.
For this application a much better option is a H-bridge (tutorial) controlled e.g. by an astable multvibrator built from a 555 timer (tutorial).
The H-bridge can be bought as a module, e.g. this one.
The timer can be bought as a module, e.g. this one.
Since the H-bridge module expects 2 control signals for the direction (aka polarity), you will have to add an inverter between the 555 module and the H-bridge module to create the 2nd signal (example).
Alternatively you could use an Areduino to create bot signals and the timing.
555 timer has 2 outputs, the second one just goes to the ground?Like this:

and this is all done with only one power source 9-12v into the 555 signal generator?Where do you get the 2nd output?
The circuit in the website behind your link in post #13 has only one output:
