Our project is about creating an easy to use device that can interface between the helicopter input for the headset and a VHF radios input for mic and output for earphone. So what needs to happen is as follows. 1. The device should be able to convert the output of the handheld VHF radio to the MIC input for the helicopter. (This needs to be adjustable for volume). 2. The device should be ab...

We require a UPS with an supply voltage of 230v AC, we need to use 2 x 12v 1.3Ah SLA batteries in series (24v DC) which need a trickle charge and auto cut off when fully charged, these will be connected to the UPS via battery leads. We require a DPDT non latching relay to be energized when the mains power is active, the two normally closed (relay unenergized) relay terminals will be connected to ...

I would like to control a PlayStation 2 console with a teensy 2 board, I would be able to connect joysticks/buttons to the teensy 2, the software on the teensy would need to read the joysticks/buttons and translate it into the PlayStation 2 protocol to control the PlayStation 2, joystick calibration/dead center would be great.
