DC motor Control, Timer

[mitchell.s]

I'm new to this forum but was looking for help.

I am planning on building a timer. What I am trying to accomplish is to turn a DC motor on for 5 sec. or so and then turn off for 48 hours.

Is there a simple circuit I could build to do this? I have seen 555 circuits but they don't seem to be able to have a duration that long.

Thanks for any and all help.

Use a CD4536 oscillator/frequency-divider/monostable.
Use a reasonable oscillator frequency then set it to divide it up to 2 to the 24th power (you work it out) for a 48 hours output.
Set its monostable to 5 seconds and for it to be triggered by the 48 hours output.

Can you give me a little more details than that. Most likely I'll be buying a bread board and soldering jumpers between chips but I don't know how to do it. Possible Schematic?

Start by looking at the datasheet for the CD4536. It tells you all about it.
