A twelve-pointed star, drawn in copper four times.

The Star Coil Plate is a circuit board we designed from scratch for radionics and frequency work. Inside the board are four layers of copper, and on each layer runs a triangular coil, wound inward towards the centre. Each layer is rotated against the one above it, so the four triangles overlap into a twelve-pointed star - the same geometry seen in many radionic and sacred-geometry plates, but here every line is a conductor. Because the board material is translucent, you can hold it to the light and see all four coils glowing through each other.

Three ways to connect
Every lab has different cables, so we put three inputs on the edge of the board:
- 4 mm banana sockets (red / black) for classic generator leads,
- a BNC socket for function generators and frequency generators with BNC outputs,
- a 3.5 mm audio jack, so you can also drive it from a phone, a computer sound card or an audio player.
Choose one input at a time.

Made for our devices
The plate works with Aplicum radionics devices, including all SWCC models - plug the SWCC output into the plate and place your witness on top. It works just as well with any function generator, frequency generator or audio source.

How people use it
Radionics practitioners use plates like this as the "output" end of their setup: a frequency or pattern from the generator is sent through the coil while a witness - a photograph, a written rate, a sample or a crystal - rests on the plate. Others use it simply as a precise, repeatable coil for their own experiments with frequency, geometry and intention.

Built in our workshop
We design the PCB ourselves, solder the connectors by hand and print the protective frame in-house. The frame raises the board, protects the solder joints underneath and lets the plate lie flat and stable.
