related idea...

free flight timer. last night i made a biplane cobbeled together from parts i had no use for, old wings and tail rotors that where too small. the thing flew very good, but i was afraid to lose it.
so i am building a free flight timer, 15 seconds to 5 minutes. i will post code and schematics when it works. gonna be SMD

asm code...

got the Tiny25 code written and it should work, but i will try it later.
a mosfet is on PB1, the other 4 ports control the time of the flight,
10 seconds, 15, 30, 45, or 60 seconds.
will post results later.

well, i made one and it worked! timer was simple, 30 sec flight with some basic profiling. it was smd and if i can now only get a smaller iron i can make smaller boards!
the end of this project.
