gnipihz Posted April 7, 2005 Report Share Posted April 7, 2005 I'm a total idiot to electronics circuit... any kind soul pls help me.i'll like to build a circuit that can 1.) close a switch to another circuit for a duration of 5 seconds.2.) after this 5 seconds, the switch opens.3.) wait for 10 mins before step 1 is repeated.4.) I'll like to have this repeated for 30 times.thks awfully. this will be my first electronics project! hope i can pull it through.

Kevin Weddle Posted April 7, 2005 Report Share Posted April 7, 2005 A simple RC circuit has it's limitations with repect to accuracy. I would not investigate wave shaping techniques. It is my opinion that you can't correct for the inaccuarcy of a capacitor through the use of semiconductors. A capacitor is just perfect in every sense when it comes to semiconductors.

Guest Alun Posted April 8, 2005 Report Share Posted April 8, 2005 I'm a total idiot to electronics circuit... any kind soul pls help me.I would like to help you, but there is really no newb friendly circuit to do what you want, the circuit I was going to suggest would require many components and would probably be beyond your current electronic capability.Sorry I couldn't help you, I I were you I'd try a simpler circuit before jumping in at deep end.What do you want this circuit for?

gnipihz Posted April 8, 2005 Author Report Share Posted April 8, 2005 i'll like to it be built as a control to connect my IR digicam's remote control so that i can take star trails at night....=(if there anyone out there that can help me with this project? i do not need high accuracy but something that can close a circuit every few mins for a few hours.....

gnipihz Posted April 11, 2005 Author Report Share Posted April 11, 2005 anybody else out here that can give some tips abt this circuit? :) maybe point me to a general direction where regular delay actions of a circuit can be studied?don't look down on gals..... once i get this up, i'll post it here to show u guys. i just need to read up more and test it out. :P Quote Link to comment Share on other sites More sharing options...
Shahriar Posted April 20, 2005 Report Share Posted April 20, 2005 Dear gnipihz If I were you I would use a mcs-51 microcontroller (i.e. 89c2051). Its programing is vey easy and U do not need any cpmlicated circuit.If U do not know programming U can ask a friend to write it for U but ifU are a little bit inteligent U yourself can learn it in just three days.HTH - Shahriar Quote Link to comment Share on other sites More sharing options...
