Martin Thomas shows us how to interface Atmel AVR witg graphic LCDs: This is a C-library for avr-gcc/avr-libc to access SED1520-based graphics-LCDs. The modules used to develop the library only support “write to LCD”, read-modify- write on the display RAM is not possible. So this Library uses a “framebuffer” which holds the display-content in the […]

[Roland] has already built a few very cool and extremely realistic flight sims, but his latest project will put his current rig to shame. He’s building a six degree of freedom simulator based on homebuilt linear actuators of his own design.


The actuator is powered by a large DC motor moving timing belts along the length of the enclosure. These timing belts are connected to a shaft that’s coupled to the frame with a few bungee cords.
