Quite right AG, I've come across some that have very obscure numbers which led me to that conclusion when trying to make 2 receivers work that I bought from Ebay....They might use ICs that are specially made for them but you can't buy the ICs.
I guess you are pointing out that the cost of reverse engineering would be exorbitant.Of course it is, but is it worth it?,
oh, mine does use purchased radios, I guess that is what he asked how to build. I may dabble in using a transmitter and reciever module sets to do it. But for now buying the radio and just building the motor control circuitry seems like the practical way to go. And I'm not going to actually build the transmitter itself at home in either case.THose radios in particular run on protected frequencies so you can't legally DIY one.
I am from mechanical eng. I do have interest in electronics & have basic knowledge about it.Some receivers have pic micros in them for dsp
The code may be protected........
what about the cost of getting type approval?I guess you are pointing out that the cost of reverse engineering would be exorbitant.
It will be impossible to even think of manufacturing the product at $35. The only way to solve this problem is that I manufacture the radio inhouse.
I think your point on designing my own radio is more practical & also considering everyones guidance on this thread.If you are planning on doing this for buisness, then the ethical thing to do would be to design your own. If you get together with a manufacturer, which you will have to do to mass produce the component boards, they may be able to help you. Even if you don't care about copying a design, you will work harder to replicate their chip than you would have to to make your own design.
On a side note, I have been working on learning how to make RCs and as I make the project and learn I am developing a tutorial walk through of it at the same time, when its done and refined I will make it availible in the projects section here and you are free to use it.
