supersimple esc's and quadro-update

a little info i couldnt find anywhere else. while programming my quadrocopter, i somehow messed up the throttle start and end-points of one of the esc's. the motor started only when the throttle was already in the middle. after some googling and experimenting, i found out how to reprogramm the endpoints. this will probably work with other esc's too.



here's the exact procedure:



- connect esc to receiver and motor, do NOT connect battery

- on the (turned on) remote move… Continue

quadrocopter

a few weeks ago i decided to build a quadrocopter. this would be a real challange but still inside the capabilities of the pcb i made. i actually designed it with plane-uavs in mind. but there's no reason it wont be able to controll a quadrotor.



here's the finished board connected to a display. the display i a cheapo 128x64 graphics lcd controlled by… Continue

6-legged walking roboter



slightly offtopic, but the servo-interface might be of interest to some people. here's my 6 legged walking roboter. there are 3 servos for every leg.…

prototype of my uav-pcb



because there's no easy way to connect the arduino to a normal perf-baord (stupid 2mm space between digi7 and digi8) i decided to make it the right way from the beginning. so i downloaded eagle and played around the last few days. this is what has come out. :) i plan to use the arduino bootloader and just connect the few needed pins to a empty diecimila board for easy programming. all the traces are already handrouted.



i'll use the… Continue

best way to read a servo signal on arduino

the atmega168 on the arduino has a timer1 which has input capture capability (see this application note and datasheet for atmega168 for details). using it, it's possible to do the pulse timing in completly in hardware (no errors, no jitter), and having a interupt readout the measured time.



here's the code:



unsigned… Continue
