Building the tropical end-of-year present from Boldport Club, Project #20 - ananas!
Here's a quick demo .. (with special customisation)
Project #20 is the first designed by Ben, the new Boldporter. And it's a beauty!
As is often the case, a small but interesting circuit is at the core of a beautiful design. The circuit is essentially four repetitions of an RC phase-shift oscillator.
Like other projects such as the famous Cordwood series, the design employs multi-board symmetry and 3D construction.
Unboxing and Parts
Boldport packaging and design just goes from strength to strength. What a beautiful kit!

Details of the circuit are available from the ananas product page, but here's my transcription (I tend to do this just to ensure I understand the circuit properly).
