Speaking timer for Futaba T10CP TX (ARDUINO NANO)

thingiverse

Because I'm a little bit jealous of the newer models of talking transmitters, I've built this speaking timer. There are two main timers. One is the throttle timer, which starts counting up every 15 seconds when you move the throttle stick upwards. The other timer tracks total flight time and announces it every minute if no throttle is given. When starting up, pushing the switch allows you to adjust the volume of the MP3 player. To do this, you need to calibrate the stick movements for height and direction. "CAL/BOT" appears on the screen; push the high stick down in the middle to start calibration. Next, "H(ight) D(own ) - D(irection) L(eft)" will appear on the screen; press the stick down and left to complete the first step. Then, "H(ight) D(own ) - D(irection) R(ight)" appears on the screen; push the stick down and right to finish calibration. Once calibrated, moving the high stick down and direction left reduces the volume, while moving it down and right increases the volume. The system includes an alarm that goes off after five minutes of inactivity on any of the elevator, rudder, or throttle sticks. A small OLED screen displays both timers and the minimum throttle time in milliseconds. The Transmitter trainer output is connected to Arduino pin D2 (interrupt pin). You can find the Arduino program and MP3 files under Thing Files. A software update has been made to version 10, with fine-tuning for the "NO activity alarm". Since I use an earphone, you'll need to drill a 6mm hole for a headphone jack - this is not included in the RC throttle box STL file. However, I've provided a support for the earphones: "TX earphonet.stl", which can be glued onto the "RC Throtle TX plate.stl" plate.
