RemoteSensor
RemoteSensor is a more advanced example for using Objective Development’s firmware-only USB driver for Atmel’s AVR microcontrollers (AVR-USB).It is a more advanced example because it utilizes an interrupt endpoint to indicate to the host when new data arrived, demonstrating how AVR-USB handles a second endpoint. The receiver part is basically a serial to USB converter with special processing for the wireless protocol such as data integrity checks and data block buffering.The system consists of the wireless sensors based on the low cost ATTINY26 microcontroller, the receiver running avr-usb on an ATMEGA8[read]
Quickie Servo Tester
This servo tester is based on a ATMEL AT90S2343 MCU with 8 pins. This little MCU is very nice in that it has 2k of Flash Program ROM, 128 bytes of RAM, and 128 bytes of EEPROM. That is a lot of power in a little 8 pin package. It has five I/O pins of which we are using four in this project.[read]
TACHOMETER
Generally tachometer is a gauge to measure rotation speed of any rotating things. In RC hobby tachometer is the instrument for mesauring and monitoring propeller revolutions per minute (RPM). This tachometer has some additional functionality like: thrust, pitch speed and power estimating.Some features:based on ยตC ATMEL ATmega8L and LPH7366 (Nokia 5110) LCD, RPM measuring range: 100-99990RPM, measuring resolution: 10RPM,measuring accuracy: better than 0.5%,thrust, pitch speed and power estimating,battery discharge indicator,auto switch off,one CR2032 battery powered.[read]
