Hello forum,
I am trying to build a small project to enable serial communication between 2 peripherals. Right now I use an audio stereo cable/jack with 2 pairs and ground. The 2 peripherals are never further away than 50 feet. Right now running the cable is a pain so I want to replace it as long as the project is kept under $50. Much more than that and it would be more cost efficient to just sell the peripherals and buy a new one that will not need the cabling.
This solution will be applied in the field so it has to be battery powered although one peripheral is powered by a pc usb port so I could use another of the pc usb port for power on that end. The other peripheral end is powered by a 9v battery and I am not sure that battery could take a much higher load and still remain efficient but that can be determined later.
At this moment all I can use is the commercial software to control the peripherals and its communication so I would like this project to be based on bluetooth technology if possible so later on I can possibly write my own gui and skip the serial to usb peripheral and use my bluetooth in my pc to receive the serial communication.
I seen the arduino stuff but it is just too pricy. I have consider trying to use an old home wireless phone and adapt it but I am not sure about the power problems and the usage average time is 2 to 4 hours so there are not many wireless phones that can handle that much tx/rc time on battery especially a battery that is as old as the one in this phone.
Any help will be appreciated. I have a background in electronics and have done many projects and design a few things for myself including game cams back in the day where those will cost you $300+ ( used a old cheap vivitar camera, an ouside motion detector and designed the board with the logic to made them work) . I have etch my own boards, had a little shop for tv/radio repairs back in the 80's when I was a teenager. I just have been away from design for so long I feel I am a dinosaur.... So, help the old man out please!!! lol!
Thanks!
