Open-Source Microscope Illuminator

Stephen Richardson of Tangent Audio built the AZIZ light ring for his Bausch & Lomb stereo microscope.

AZIZ is an LED microscope illuminator that I designed and built from scratch. It is designed around a Texas Instruments TLC59116 constant-current PWM LED driver chip, and an Atmel ATTiny1634

AZIZ has 64 LEDs, half super-bright and half diffused, and you can select from 10 preset patterns with the ability to manually control the brightness and other settings. Steve has a Github repository if you’d like to make your own.

  1. This is totally a n00b question, but can a guy flash that chip with an arduino, or does he need a more legit chip programmer?
    …That unit is super cool!
