Hi /diy/, I have just took my graduation in electronic and telecommunications, and I'd like to test my skills building a theremin in the cheapest way. After I had this great idea, I realized that I'm not so good at inventing, so I was wondering if someone have a schematic and a PCB or a master of the necessary circuits, and some tip to share with a bro. Thanks

So I have a self-propelled mower that I want to use, a servo to pull the power wire will do fine for the propulsion(the lever on the handle has a wire that when pulled makes the front wheel drive move forward). Since it is front wheel drive I'm thinking of putting the batteries and control systems on the front with just the steering rack in the back, more weight in the front means the wheels will get better traction.
I don't plan on modifying the motor/ bed much. The remote controls and steering system is all I'm adding and they will be separate systems from the motor and propulsion.
So what is the best way to go about turning it? Is there such a thing as servo motors big enough to turn a steering rack for the rear wheels, and could it be simply powered by something like a car battery? What about a pneumatic turning system, would that be easy to do?
My main concerns here is spending minimal money on this and having it be not too complicated. I already have a remote control for it, and I can build some simple power relays and control circuits for it.
So does any /diy/nosaur have experience with RC mowers? Or better yet know how I could make a simple turning system for this?
Making an RC mower but don't know best way to make turning system. Again, I plan on using the self-propelled part of the mower for its propulsion; so the steering has to be separate from the propulsion system. Picture related, it's the mower I'm modding.

Well, hello there,
I was planning making a Mario (N64) for my Modelation and Representation class.
And I was wondering if it was possible to put in her back or something (like some music incorporated teddy bears) a music box wich plays Mario Brothers music (I hope you know what I'm talking about).
There is any way to create a music box (like the one who have the talking toys or teddy bears) with customized music? I mean, I am not en engeenier or anything related to that, just a IT Guy (lol). So, any chances to create or easily made what I am talking about?
Pic realated, that was an early stage of the Mario.
