Hello
I am involved with Surface and submarine remote control, 75 mHz, FM only. What I have been thinking about making is a set of external switches to physically add to one channel of my transmitter. I would disconnect that control pot inside the transmitter and add the wires from the keypad. Say from a transmitter stick, up is a signal wire, down is a signal wire and black is ground.
I would be interested in either 8 or 16 functions from the keypad to the matching receiver that would be connected to the transmitter`s receiver on that channel now dedicated for this use. The individual either 8 or 16 functions could be set to momentary, as long as that keypad button is pressed or latched, you press the keypad number once to start the function then again to stop it.
The unit would be powered from the main battery, 6v to 12v. and there needs to be a power on LED indicator as well. Each channel should be able to run a max. of 1 A, small d.c motor, radar, turn on LED`s or a sound system or smoke system or motor for the anchor etc. Also there should be No effects on the receiver circuit if the main battery is disconnected, once setup is done to the user likes, it should stay in the receiver until the user changes the settings through dip switches for each channel.
Can anyone help me with a working circuit and a source for the needed keypads, either 8 button or 16 ? I have checked into the Hobby suppliers and one has the unit I am interested in BUT that person`s product has a high failure rate with POOR customer service etc. and the other supplier is VERY expensive.
Can this be done without PIC technology, as I have NO knowledge of PIC`s and the programing needed to make them run. Regual I.S, Tansistors and Programmed EEPROMS, I could pay for.
Please let me know if anyone knows of a working curcuit and sources of special parts.
Thanks Again for Your Help.
