For a bit of history and understanding as to my reasoning, check my previous post.
A standard R2 dome has 3 sets of lighting in it. There are other options, and builders will constantly be adding new things, and as we use the ReelTwo library, things are relatively easy to add on.
I have designed a set of front and rear logic boards using 2x2mm WS2812B LEDs. This means that you can get an array of 27×4 to fit nicely into the area for the rear logics, and 9×5 array for each of the front logics. The mounting holes are in the same position as the teecees ones which should make it nice and easy to mount.
The PSIs are more detailed in these posts, as these were my first attempt at getting PCBs manufactured and populated.
This was what gave me the confidence to be able to go ahead and have a go at doing a full logics set. Not just from a technical point of view, but also how low the cost was.
The HP servos are not included in the setup, but can be added with a small code change and a PWM servo module.
As the main processor, there is a choice between an Arduino Mega, or an ESP32. I have been running ReelTwo on a Mega for a couple of years now with no problems. The ESP32 brings a much more powerful processor as well as wifi and bluetooth to give other options for triggering effects.
By default the lighting system will run standalone. Standard patterns on the logics and PSIs, and the HPs will randomly turn on. However, if you want to trigger effects there are many options.
- Wifi – Serial
- Wifi – Marcduino Serial
Currently, I’ve only tried i2c, but will be testing the Wifi option and integrating that into my r2_control software.
