A very fitting aesthetic for the cracklebox project from Worth Ekik –
I strongly recommend building this if you like noisy toys. The touch-pad interface is fun, and a nice change from the more traditional knob or key methods. As far as musicality goes, it’s not great. However, it is capable of some very interesting ambient textures such as white and pink noise. It even has some Theremin-like capabilities (see the video for me waving my hand over the pads). It’s pretty unpredictable, but if you can find the 709 chip, this is a great box to experiment with.
The LM709 chip is unfortunately no longer made – its pins have a unique responsiveness to touch unlike other op-amp ICs – they can still be found on auction sites now and then. – Cracklebook
