sac help?

[kaiipoo_]

Hi guys.

So i have a SAC on U3: AOS2: Electronics and Photonics
and it's basically a multimedia presentation, in which i have to present a circuit, explain the theory behind it (changing variables) and it's main function + purpose.

My teacher has encouraged my class to look all around the web and find an appropriate circuit (provided we acknowledge sources and give credits ofc)

However i havn't really found any simple enough to lie within in the scope of the year 12 course, and thats what i need help with.

Could somebody give me any ideas or link me to any relevant web pages ? Help would be greatly appreciated. Thanks !!

Hmmm, you could just make your own. However, this does bring back childhood memories of Dick Smiths Funway kits, where you make electronic circuits (I had an awesome childhood I know )

Heres just a site I got from google, http://tronixstuff.wordpress.com/2010/10/13/australian-electronics-nostalgia-funway-kits/

If you're really interested, I can have a look around and maybe find some circuit diagrams

that'd be awesome bro haha cheers !

I was thinking of making my own, but i have no idea what kind of circuits would be considered too simple or too complex.

I was thinking of having a thermistor voltage dividing circuit used to control something like, an air conditioner or coolroom?

Sorry mate.. Had a look round everywhere. Not much on the net on Funway kits, and every circuit except the first one (led + resistor + battery) required a transistor or capacitor or other electrical components not in the physics 3/4 course.

Any sort of voltage divider would work fine for your purposes I think . Worst comes to worst just go steal some diagrams from VCAA haha. At least your teacher can't complain about those circuits!

Good luck with it
