 Solar Controller The Solar Controller is a unique light-driven controller that generates control voltages directly from two independent solar panels. Each panel outputs a variable voltage between 0–5V, depending on light intensity. This allows you to play the controller like a Theremin with your hands, a lamp, or any moving shadow. Use it as a standalone instrument or patch it directly into your Eurorack system. ⸻  

• Two Solar Panels – Independent CV sources (0–5V) – React to light intensity and movement

• Triple López Gate (built-in) – 3 mechanical switches for gate triggering – Play finger drums directly – Or send gates from LFOs, sequencers, or triggers

• No Power Supply Needed – 100% solar-powered – Positive-only voltages, safe for your system

• Connectivity – Mono 3.5mm jacks, Eurorack compatible – Also works with standalone synths, pedals, and other gear ⸻  

• Perform gestural control like a light Theremin

• Trigger gates and rhythms with your fingers

• Animate parameters with natural light changes

• Pair with sequencers, LFOs, or drum machines
