IN-9
in-9-nixie-testing-rig
Driver schematic: https://www.dropbox.com/s/g6m7f94mk7rfxy1/IN-9_PWM_driver.png?dl=0
Circuit built for testing the tubes. As you can see some of them have issues. According to the seller I should let them work for a while and the issues should disappear.
Power supply is unfortunately not capable of supplying enough current to light all tubes at once (10x12mA at 130V). So I had to turn max 2-3 tubes at once. Power supply was for free with the tubes so I don't complain... much.

LASER
laser-servo-projektor-na-arduino-test
Nagrane ~styczeń 2011.
Zrobione w jakieś 1-2 godziny, skład:
1. 2x mini servo modelarskie
2. Wskaźnik laserowy 10mW + klamerka (włącznik na stałe)
3. Talerz z twardego dysku - lusterka
4. 1x Arduino
5. 20 minut pisania softu + kalibracja
Niestety sprzęt nie nadaje się do poważnych 'wyświetlaczy' - serva są za wolne.
Obraz w rzeczywistości wygląda o wiele lepiej, ale i tak widać migotanie i proces rysowania literki.
