Start through a work beacon through a base made of perfect materials: diamond, gold or iron. My example has a 3 x 3 stole base. As long as the beacon lights up, any kind of variation is functional.

You may broaden this model as you view fit. In my instance I have tried to recreate the 7 classic rainbow colours, Red, Orange, Yellow, Green, Blue, Indigo and Violet. If you have actually no idea how piston feeding takes work, never ever mind and copy my instance exactly.
These are stained glass blocks. If friend didn"t know, hold transition to location blocks without connecting with the beacon.
Add a border as shown and also pistons (non-sticky). The void is left purposely for toggling the piston feed clock on and also off.
If girlfriend don"t know what a clock is, it"s a circuit the runs on loop. This feed system powered one piston in ~ a time, approximately a circle. I"ve found that the best interval because that this setup is five ticks; one repeater set all the way back to four ticks and also another collection to the default one tick. If you are copying mine design, all the repeaters are dealing with a clockwise direction.
The inner piston will certainly cover ad uncover the beacon, successfully cutting the beam on and also off. The outer piston will open and close the clock. These will enable the rainbow beacon to turn on and also off. Ns guess this is optional.
This is how a switch deserve to be added, over there is a torch in ~ the finish of the redstone line, as indicated. This gives the "beacon blocking" piston "ON" or "blocking" together the default position.
The sticky piston to the right of the bar is component of a signal size shortener. The repeater is facing away indigenous the piston and is collection to 2 ticks (the minimum signal length for a piston to function).
The bar cannot be replaced by a redstone line. Where, the period of redstone prior to the piston is must be a signal towards the piston. Change it through a repeater encountering into the piston if you want to placed the bar elsewhere.
You might now test the circuit. If the rainbow beacon is currently functional by itself, girlfriend will an alert that the beacon beam will flash white in between the color changes. This is because of a an insect that makes relocating blocks "invisible". The next few steps will solve this.
Build an additional layer the stained glass blocks, pistons and also border. This 2nd layer will certainly be comparable the the lower one however, this clock will run a tick slower. This fixes the trouble by making sure that over there is constantly a stationary block over the beacon.

Bring the signal up utilizing top half slabs. Top slabs have the right to have redstone above and through them, solid block won"t work. The repeater automatically after the slabs is collection to one tick.
