Hey Forum members,
I have recently gotten into armature rocket propulsion research (like Hybrids, Liquids and chemical acid based oxidizer motors) and need a means to safely fire them from 250m plus (A CATO from a MYROL rocket isn't something to be laughed at), but as well from firing the actual rocket there is ground support gear that needs to be remotely looked after such as fill stations and heaters ect. probably 4 things in the end need to be initiated
I am looking into a WIreless/radio system
However I need this to be safe and as I have stated I don't want to be any ware near a tube full of well, explosives.
The risks of things going wrong is to high and thus wanna get away from them.
I was thinking of 3 possible ways
1. I could use simple 433mhz radio module and then use an encoder and decoder system...
2. I could get to micro controller stamps (basic stamp, picaxe, arduino)
then inter face them with an XBEE rf module. this way I could have the Transceiver send a string to the receiving unit and it would then match and let commands be sent or actively refused which eliminates my stray signal problem. However that's eaisley over $200 and i don't have the money to do something like that.
3. The jaycar sms I/O controller this is perfect aside from 1 thing.
The Australian mobile telecommunications backbone isn't that good and optimality I would like to be in the middle of the bush away from any people that could accidentally walk inline (I don't want to put anybody in danger!) I just want the tests to be performed at remote safe locations.
I could relay use the help of someone to help me with the schematics as Im a Chemist not an electrical enginear and don't have a massive knowledge on the subject. but I understand the basics and moderate stuff ( I can follow a IC's data sheet)
Cheers,
Kwinchee
