Solar operated timer - NEED Help Please...
Hello everyone!
I need help!
I have an idea of a product I'm designing to get accepted to a design school.
I need help since I have very little knowledge in electronics.
I need a circuit for a timer... an egg timer with a twist (I think)
Should have a switch (click type), 1 Buzzer, 6 indicator LEDs, and I take it that some kind of Controller (I have no idea what kind) and should work with solar power.
Should work as follows:
You press the switch once - one LED is lit and the timer count back 10min. and then the buzzer will go off. press it twice - 2 LEDs are lit and it will count back 20min till the buzzer goes off... and so on up to 60min.
If 6 LEDs are too much for Solar power, 3 are also OK (30 min timer) or NO LEDs, but a "beep" indication for each press / 10min. time.
I hope it's possible
And thank you all for your HELP!!!
Take a look at the attached picture... Just to get a laugh

Did you still need help with that timer? I know your post is rather old at this point...

No thanks :) Project is done long time a go... thanks again ET:)
Did you document the project? If so, where's the Instructable? :-)

Here are a couple of basic circuit that you could use, I am not that great at electronics either but these instructions are rather simple and should help.

I hope this is helpful, I am planning to build something similar to this, to use as a timer. Good Luck
