Notes
Build logs and technical notes
Working notes from live installations and the workshop: what broke, what fixed it, and the measurements behind the decision.
- Four screens, one frame, no internet The first real install of vj-show took ninety minutes and hit five problems. None were in the renderer. All of them were in the networking around it.
- Budgeting sACN universes before you buy the strip Universe count, packet rate and switch capacity are one problem, not three. Here is the arithmetic I run before ordering any LED for a show.
- GLSL feedback loops that do not turn to mush Ping-pong feedback is four lines of code and a hundred ways to lose contrast. Notes on decay, clamping and keeping a loop alive for an hour-long set.
- Getting DMX timing right on an ESP32 The break, the mark-after-break and why bit-banging DMX on a WiFi-enabled chip is a bad plan. Using RMT and UART hardware instead.
