Square Wave Generator with the sound it makes!

My first attempt to learn more about electricity as it pertains to ignition systems in engines. This uses a 555 timer and a LM393 comparator chip. I put a speaker on the output to hear the signal as I do not have any kind of scope to watch it with. I got the specifications from the great people at this site: http://www.rmcybernetics.com/projects/DIY_Devices/homemade_signal_generator2.htm

@toyerrie I understand... It's like the fingernails on the old slate chalkboard kind of thing.

@9020powrmax You are too kind Sir. My Father used to say "A borrower or lender never be". But it is good having YT friends that I know that have that stuff!

Hallaran, I'll loan you an oscilloscope if you need it. Just come and get it. I'm scope poor as it is. Lol....

@Hallaran I fully understand the reasons as to why you didn't turn it off after explaining what was going on but for me personaly i can't stand a sound like that for very long because it's like a pet peev of mine... And to be very honest with you i have a strong irritation with door chimes on cars just drives me up the walls...hahaha

@Hallaran well keep up the good work

[Hallaran]

@toyerrie Yes the noise was a little irritating, it was the only means I had to indicate that the frequency existed. Trying to explain something new at and to do a good video can be a bit of a challenge... Thanks for your comments!
