Armed with four wingtip-mounted Sienar Fleet Systems L-s9.3 laser cannons and a SFS P-s5.6 twin ion engine, the TIE Interceptor has become the scourge of the Rebel fleet, nearly capable of out-running and out-maneuvering the beloved A-wings of Nomad Squadron. Because of [Matt]’s tireless work, we can now visualize TIE Interceptors on approach with our targeting computers oscilloscopes.
[Matt]’s oscilloscope visualization of a TIE fighter is a huge improvement on previous scope displays we’ve seen, considering [Matt] used very minimal hardware to display 3D graphics. The build uses an ATMega88 along with a 10-bit DAC to draw lines on the screen. The capacious Mega88 with 8kB of flash and 1kB of SRAM was nearly filled to capacity with [Matt]’s project; to improve the rendering speed of the display, sine & cosine values are pre-computed and stored in flash along with division tables for common values.
The rotation of the TIE fighter is controlled by a serial connection to [Batt]’s desktop. It’s a very impressive piece of work that looks like it would fit into the cinematic aesthetic of The Empire Strikes Back. Check out [Matt]’s video of the TIE rotating in space after the break.
