Momentary Output Pulse

Using this diagram: How would I extend the pulse to 5 seconds instead of 1/2 second? Multiply the capacitance of the polarized cap by 10 which would equal 10k uF? I searched the internet for 2 hours and couldnt find a simple circuit to do what I want so I was hoping someone here could help me out. Thanks in advance.I drink current, eat ohms, and bleed voltage

I've used a 528t before and it would work but I would like to add some more knowledge to my bag of tricks by using a relay, cap, & resistor and understanding how that circuit works.I drink current, eat ohms, and bleed voltage

This diagram gets posted on his website and no one knows how the cap/resistor values are calculated and how that relates to delay in seconds?I drink current, eat ohms, and bleed voltage

Read here for more info: http://www.electronics-tutorials.ws/rc/rc_2.html The delay will depend upon the coil resistance, drop out voltage of relay, capacitance value, parallel resistor value.

Excellent! Thank you for the info and direction. I really appreciate it.I drink current, eat ohms, and bleed voltage

This is my first post on this forum so please bear with me. Im using a bluetooth speaker as a transmitter and a power amp to eliminate the radio in a older car and what im wondering is how i would use a constant power sorce (ignition switch on) to send a single pulse to the speaker toeeliminate a tactile switch. I already have a DC/DC Converter 12v Step Down to 3V/3A Power Supply to send the proper voltage just not sure about the constant to momentary. Any help would be greatly appreciated.Luhanz
