There is the project I build for my two years old son. He like playing with all kinds of buttons he found everywhere. But they almost done nothing for him, except the ones on my dryer. So I decided to give him an box full of buttons that take different action on lights and a motor.

For my son and for many other kids, it's not only what the buttons do, but how to manipulate them and trigger them. So it's a fairly choice to get different types of buttons like one you swap, some you lift, other you pull or push. So I found about 10 types of buttons from an electronic store nearby.
The actions I planned for the buttons is to trigger some lights and one motor. I have chosen leds for almost all of them except for two, because I wanted the box to work with batteries. I used four C type batteries, so the box works a while with this power source.

If you want to replace battery system, maybe you can use the "joule thief" method to save in battery cost... ;)
You will get some current flow through the bag which will reduce your battery life.
You would be better off with a "normal" plastic bag.
I guess that English is not your first language: there are some odd grammatical constructions in your text. If you are not offended, I would be happy to make some suggestions for changing the words here and there.
But you can find the circuit for the flip flop here http://www.josepino.com/?led-flasher-circuits1. I use the second circuit with the 2N3904. Try first on a protoboard for the resistor and capacitor values. If I remember correctly I use 100uf capacitor and 1k resistors. Not sure at all. For the And Gate I use this circuit http://hyperphysics.phy-astr.gsu.edu/HBASE/Electronic/trangate.html. Every LEDs need to be wired with a resistor. You can use the classic V=IR formula. In my project I use 470ohm. There OK for the high brightness LEDs, but to high for normal LEDs. For the rest, is only wiring a switch with a LED.
I hope I answer your question at best.
And color codes 0-9, lighting colored bulbs.
I show the buttons box to friends and family and they like playing with it too! It's a really fun and relatively simple project to build. And to play with it too.
Thank you all for your comments and your appreciation!
When I was a kid I had a giant wooden chest made from MDF to put toys and stuff in, and I cut loads of dials and pretend switches from cardboard to stick on the top so I could pretend the box was a great big machine :P This 'Ible is a wonderful reminder of days gone by, and a marvellous idea on how to revisit the past and make a great big box of buttons and switches that actually works! :D
Gonna hit up Maplin as soon as I'm able and just go crazy with switches, lights and bits of wire.
Thank you for a great instructable, and a wonderful and precious dip into a long ago memory.
