Custom remote

OK, I want to make my own custom remote control system after seeing a video on Iron Man props. The reason i am doing this is because the remote control system I bought was too big for my project: It has four channels while I only needed one. So, the only solution is to make my own.

Which (I think) is very simple since I can just follow the modules used in the original circuit. Basically, what you need is the RF transmitter and a matching RF receiver. Then you would need the voltage regulator plus a relay and that's it.

Yeah, right. Easier said than done.

This is a four channel transmitter but I will only

be using one. The other three will be useless or

until I can think of another solution for it.

The transmitter is a very simple module. Here, you have

the battery, the encoder chip and well, the code sequence.

The code sequence here is just a matter of soldering the

appropriate links. They used to have miniature dip switches

but it takes up a lot of space. The only down side is that

when you want to change the codes, you have to de-

solder and re-solder it. Which might wear out the board.

And finally, here is the decoder parts. On the left

is the RD receiver and then on the right is the IC

for decoding the code from the transmitter. As for

the SMT resistors, they are to match the RF

transmitter's frequency. What is not shown here

is the voltage regulator and the relay as I have

not decided on which voltage system to use.
