@OlPhart: Thanks for all your help! I'd prefer to use a non-relay-involving switch as well, as I have never dealt with relays before. The voltage levels, just to let everybody know, can be considered the following: DC Input 1 will operate around 12V while the threshold voltage for DC Input 2...
Thanks for your help picbits!
But do you mean a SPDT relay? I haven't used relays before but a quick web search showed that SPDT relays have one common and match your solution. Please confirm https://upload.wikimedia.org/wikipedia/commons/6/67/Relay_symbols.svg
Also, I'd be grateful for an...
Hello "picbits" !
Half a second or less would be about right for my project.
No hysteresis required.
No other power supply available.
The inputs are isolated from one another.
Also, for the current rating: I'm not entirely sure yet. I'll be running a DC motor on it (a medium-sized one) with a...
Thanks for the reply!
No no, not a homework assignment. But I AM an early student, and this is the only thing that's keeping me from completing my project.
The voltage levels will be around 12-17V. And yes, the voltage in series was meant to imply addition. :)
And "OlPhart" I'd IMMENSELY...
Hello everybody!
I'm working on a project and am facing a problem I simply cannot solve. I'm unable to design the electronic circuit that accomplishes the following task:
I want to couple 2 DC inputs in such a way that when Input 2 reaches certain voltage level (from zero), both inputs...
