The relays switching at this rate will die sooner, I think you could have used a better alternative like a [2P4M] SCR or a low power GTO or simply a MOSFET Cheers✨✨
I had to lookup the relay data sheet and it’s rated for 100,000 operations 1 second on and off at 5 amps 30V resistive load normally open. My crude math is about 55 hours of continuous use. In reality, I’d probably go insane way before those relays fail! Cheers
Hi Justin. This video is really meant as an exercise in putting a relay to work - a kind of part II to the previous one on how to drive a relay from a lower voltage. I suppose I could have done a better job in pointing out the constraint. You have very valid points about both devices being able to work at higher voltages (and the 2 bulbs in series). Thanks for the feedback! -Derek
@@AmRadPodcast This is perfect example of why you might use simple logic chips instead of a microcontroller. I think building it with a microcontroller and having to deal with the regulator and then showing that you can do the same thing with a couple chips at 12v would be very illustrative to people who are in a microcontroller comfort zone. If it is just an exercise you should say "this is not how you should do it at home kids" no?
Why are you really when you can drive down to lambda roughly with transistors you can use a transistor away those lamps aren’t trying that much current
I love the sound of the mechanical relays clacking away. Very nostalgic. Great video and clearly explained. Thank you for sharing!
Great video thanks, keep them coming. I always learn more when it fails first time than when it works ;-)
Very nice! Keep the videos coming!
👌. How to control or interface single phase and three phase induction motor to microcontroller?

I'm not sure why you need the 5v regulator. The 555 and CD4017 should both work fine at 12 volts.
Also if you just used 12v everywhere you could always have 2 bulbs in series for 6v/bulb.
One of my favourite features of these chips as a kid was that I could power them from a PP3 battery
