Want to build something like this

[stephan2307]

Hi,

I am new here and I hope someone can help me out.

I came across this page https://www.instructables.com/id/Amazing-buttons-box-for-kids/ and I want to build something like this for my kids.

I used to be able to do all the stuff but that was like 12 years ago so have forgotten loads.

So I was wondering if someone can help me to come up with the circuit schematics.

Any help would be really appreciated.

Thanks.

Shouldnt be that difficult, all you need to light an led is a resistor, switch and battery.
You could use a salvaged mobile phone vibrator for one of the functions.
A little 9v buzzer and a beeper would also make things more interesting for a little one.

The apprentice department one place I went to used to make similar things for disabled kids, in a larger box with painted up fronts, clowns, animal faces and the like.

Heres a beginners to electronics guide for lighting up led's

thanks will have a look at that.

it might be an idea to get together the bits you want to use like say leds switches buzzers or whatever then come back for sugestions on what to do with them, it will give people a better idea of what you have and i am sure you will get plenty of help/schematics.

I've build a couple of similar boxes for kids. The more complex and unpredictable they are, the more fun they are.
Just use any old switch you can find. Rotary, SPDT, 4PDT, push buttons, anything !
Buzzers, motors, vibrators, LED's, LDR's.

You can add more complex circuits. One switch I had did nothing, but it was wired to a capacitance circuit. So if somebody put their hand near it, it would turn everything off momentarily. The kids though the "secret switch" was the most fun, and they would spend hours trying to work out what that switch did, but every time they tried to change it, everything went off before they could even touch it.

A friend built this one many years ago.

He didn't build it for children, though he was a big kid.
It was originally a guitar amplifier. I made a passing comment that it was a bit of a dull looking thing, so to spite me he decided to make it "better".
It has an audio amplifier and an AM and FM radio built into it as well as a microphone and line in inputs.
It has some (many) surround sound delay lines in it and each of these can be switched, mixed, and fed back on each other.
Their delays are variable and there are several oscillators, mixers and other weird audio circuits one would only expect to find in RF circuits.

The sounds this machine can produce are even extraordinary for a Dr Who soundtrack.
One of my favourites is the simplest. A variable delay line is varied with a 0.2Hz sine wave.
Put the radio on to a new reader and they start to talk real fast before they slow down and speak slowly and then start talking fast again.
Rather than using a sine wave, a square wave can be used and the effect is sudden rather than gradual. The amplitude of the bias oscillator controls how fast or how slow the delay line works.
It doesn't take long to realise that even with only a couple of variables, the number of switches and controls can be very large.
