Morse Beacon is small transmitter that can send flight telemetry to earth from a small balloon or model plane like temperature and battery voltage, Call Sign identification and a sequence number for logging purposes. The design is made around an ATtiny13 microcontroller, a LM35 centigrade temperature sensor (or LM34 Fahrenheit), a RF module, and [...]
The Low Cost Telemetry Device (LTD) provides a low cost, minimal parts count Telemetry keyer using an Atmel’s ATMega8 Microcontroller. The LTD sends data by measuring voltage levels of up to four analog channels via its on-chip 10-bit Analog to Digital Converter (ADC) and converting them to numbers and sending the measurements via Morse [...]
You can collect vital flight information about RC aircraft with this clever on-board telemetry module. The module sends information via a wireless ZigBee link to a ground station consisting of a laptop computer and a ZigBee receiver. The system is implemented using an MC1392 SARD board with a few modifications. A voltage follower built with [...]
