- How this started:
- Wanted a basic Lumia cue that was a very slow beam through a difraction grating or along a rotating torture tube
- Did not want to use an Computer+FB3+Beyond just for a simple slow moving beam - I still needed Beyond to run other content
- Also wanted to produce test patterns without a Computer+FB3+Beyond for bench testing, alignment, tuning, etc.
- What is it?
- ESP32 (dual core microcontroller)
- One AD5328 8-channel 12-bit DAC for X,Y,R,G,B,Shutter, and Left/Right Audio channels
- +/-10v bipolar power supply
- Op-Amps: TL084 for X/Y and MCP6004 for RGB+Shutter
- Adjustment pots for X and Y Gain and Offset
- DB-25 ILDA Out
- Built-in 4-line OLED status display
- Powered by any 5volt USB-C source or a portable USB battery pack
- Integrated SD card (included) to store ILDA and WAV files (can support cards up to 64GB)
- Audio: 3.5mm line-level audio output jack to send audio to any amplified, powered or Bluetooth speaker (using AUX input)
- Features
- Entirely self-contained; no computer needed
- Slightly larger than an FB3 (see photos above)
- Control over Bluetooth via iOS or Android mobile app
- Control over WiFi from any web browser via built-in webserver and web app(both network Wifi and ad-hoc AP network modes)
- 12 common test patterns
- Adjustable scan settings (Scan rate, Scan size, X/Y offset, Blanking Shift, Brightness, invert/flip XY axis)
- Individual color corrections for Red, Green, Blue
- 40k scan rate in non-point-optimized mode
- 70k scan rate in point-optimized mode
- Static shapes and beams with adjustable brightness and color changing effects
- Upload your own custom ILDA files to the SD card
- Supports frames and aminated ILDA files of any size
- Over-The-Air firmware updates (requires network WiFi mode and internet connection)
- --- or firmware updates directly from the SD card
- Programmable! You can upload your own code to control the hardware using C++/Platform.io
- Comes pre-loaded with the PhotoLexicon ILDA FTP file library (over 1,800 Animated ILDA files, cues, patterns, and gobos from X-Laser)
- Plays any laser 16-bit 8-channel WAV file at between 32kHz and 48kHz.
- Includes 64GB Sandisk EXTREME SD card for WAV file storage
- Inspiration from several other ESP-32/Arduino Laser DAC projects:
- Instructables:Arduino Laser Show With Real Galvos by DeltaFlo
- ESP32 Laser Show by Atomic14
- OSLC by Chris Favreau
- OpenILDA DAC board by Arjan (RaspPi)
- ESP32 DAC by AshEvans81/ ElectronAsh (twitter)
- Future Enhancements/Ideas in progress (but no promises, here!)
- Etherdream Emulator over WiFi
- OSC Server/Client
- DMX, ArtNet, SACN and/or MIDI control
- Several GPIO are available for future or user enhancements
