Buttons box for my son
There is the project I’m going to give to my two years old son this Christmas. 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 experience box made of many kinds of button that take different action on lights and a motor.
There are only three little electronic circuits in the box. The rest is only wiring. One circuit is a flip flop to make the two red leds flashes and the other one is an And Gate to make the two arcade button light up the yellow led only when the two button are pressed, the last one is a bicycle flash hacked to fit the panic button.
There are nothing much more to explain about this box, the pictures and the video will tell you all.
The final product
Purchased buttons and other parts
Mesuring parts
Buttons and lights placement
The box
Drilling the holes
Prototyping the flip flip and the gate circuit
Building the final circuit board
The completed circuit board
The circuit is packed in an antistatic bag. This is for isolate it from the mess of wires you will see on the next picture.

Congratulations on creating! I really enjoyed and would like to know if you can pass the list of components and circuit schematic. It would be nice one of these to stimulate thinking and perception of the little ones.

I unfortunately don’t have any schematics, plan or procedure to build that box. I purchased some buttons, LEDs and lights on an electronic supplier on the fly. I made a plan for the part disposition and start soldering thing together. Like you can see, it’s a total mess inside the box.
But you can find the circuit for the flip flop here. 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 here. 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, it’s only wiring a switch with a LED.
You can also have a little more details on my Instructables project page : The Amazing Buttons Box.
I hope I answer your question at best.

This box is amazing. Did your son like it? I wish I could make such a thing because my son (almost 1 year old) is so fond of lights and buttons. He really needs to check out the washing machine a few times during every wash to see the lights on it, and the little light on the TV too.

Thanks for sharing, maybe I will try to make a simpler version
