to mark as completed Nippon - Line Follower
Hello everyone!
This is my first LMR construction, it is also my first "pro" linefollower and it was prepared for SumoChallenge2009 in Poland. My girlfriend called him "Nippon" - don't ask me why :)
Engines' nominal voltage is 3V - I switched them directly to 6V, used PWM=254 but they were still too slow... So changing engines is my priority at the next update.
I made PCBs by myself - standard technique using iron, "smooth" paper and B327. I used special paint for soldermask, dedicated for glass (known in Poland as EnSold).

An idea for chasis was born, when I was cleaning my room - it's not a toy-car or other space ship; I used... an old CD-rack :)
LCD is mounted only for sensors' calibration - Nippon is too heavy with it.
Here are some photos - enjoy :)
Old, boring CD-rack:
Whoah! All parts fit perfectly!
Sensors' PCB and batteries mounted:
Mainboard and LCD mounted:
Radiator for L298 added (engines use about 0,8A each)
Almost ready to rock ;)
First tests of electronics attached to Nippon - everything works fine!
Mechanics:
