Hi, hey I was just curious if anyone can post or direct me to a timer circuit that uses capacitors that discharge in sequence to make leds flash, preferebly quite slowly, like (one onthousand *FLASH* two onthousand *FLASH* Three onethousand *FLASH*, etc.)? Here is the catch....I want to do this using no digital logic chips or transistors, only caps, resistors and, relays. I have already made a circuit that does this except that the leds flash really fast, too fast. Let me know...
I have a fasination with electro/mechanical gadgets, like any electronic device pre 1950, or before transistors. I guess I like it cause you can see everything happening and not being hidden inside the components of modern digital electronics. Plus I am trying to get a better handle on my understanding of things like electronics, and boolean logic. I figured for me, one of the best ways to learn would be by going backwards and messing with relays, and so I have a ton of mini 2.8 v relays. I also have been collecting old / antique electronic books. Id really like to mess with vaccume tubes as well, but that might be down the road a bit...I really dont want to electrocute myself with 150 vDC, not right yet anyway.
Thanks in advance.
