TriPython July 2018 Meeting: Lighting Macro Photographs with CircuitPython
To get full and timely notifications of all TriPython events and discussions, subscribe to the TriPython email list here ( Full information about TriPython is available on the website at . LED lighting rigs are expensive. Worse, they have little to no controls aside from on and off. Most are not dimmable and the only way to change color is to use gels (colored sheets of plastic). In this talk Stacy Morse ( will present how she used CircuitPython ( in conjunction with LEDs and microcontrollers to make a custom LED lighting rig. The Problem: Macro photography is very small scale and the standard LED light arrays are too much for a given composition. LED arrays for photography are expensive and featureless. The Solution: Use CircuitPython to control LEDs using microcontrollers to light macro photography. Our speaker, Stacy Morse (, is a time traveling immortal who programs with Python and builds things that blink. She is a freelancer/contractor building web applications. This allows her to work on her personal Python project, a hand-held programmable LED array for lighting photographs. Stacy's talk will also be featured at PyCon Australia in late August. Extemporaneous "lightning talks" of 5-10 minute duration are also welcome and don't need to be pre-announced. Lightning talks are for you to "show and tell" something you've learned about Python recently, no matter how small. We all use Python, therefore, we are always learning something new about Python that we can tell others. Plenty of free parking is available in the RENCI parking deck. The meeting will be followed by our usual after-meeting at a nearby tavern for food and beverage. Come join us for a fun and informative evening.

What we're about

This page is the pointer to ( Python users in the Triangle (Raleigh, Durham, Chapel Hill) North Carolina region meet on the 4th Thursday of each month (except the Novermber and December special meetings on the 3rd Thursdays). We welcome you to join us. TriPython (formerly TriZPUG) has been meeting monthly since 2002 and is fun-loving band of Python® zealots trying to learn more. TriPython has a very loose organization, charges no dues, and ranges from newbies to gurus. We are focused on improving the usability of Python products through self-education and outreach. In addition to meeting, we have a Python powered email list ( ), a Planet blog ( ), an IRC channel ( (, and a Twitter channel ( ). Meetings are also posted to if we get around to it. However, the TriPython email list ( ) is our main communications and announcement mechanism.
