Animatronic hawk controlled by PIC MCU

Chris Merck have sent us an animatronic hawk project which was used as a prop for the movie “Lady Hawk”. He have made 7 axis motion: wings, tail, beak, body and 3D head motion. In the video bird looks like real and alive.   For bird control he used Microchip PIC16F627 microcontroller which forms and sends RC signals to hawk servos. Author also provides ASM source code where you can study the hawk control logic. Im just wandering how did he put all 7 servos inside the hawk and kept it look like real. Nice job. Continue reading

PIC based small thermometer with USB interface

Device is more experimental and tend to be used to measure indoor and outdoor temperature. It uses PIC 18F2550 microcontroller with built in USB peripheral. Microcontroller reads sensor (TC1047A ) data and sends it via USB to PC.   USB firmware is taken from Microchip, so not a big knowledge of USB specific software is required. Hex file and other project details are available for download. Author left possibility to connect other sensors (humidity, pressure) to board and syndicate it to the web with Google earth information. Continue reading
