For EMF festival 2022 I brought along my xylophone, and Dan made the project below.
I supplied some steel components, but mostly helped by chatting through the practical construction aspects of the project.
I've made quite a lot of stuff over the years, so can be useful on a consultancy basis for this sort of thing.
I ought to do more consultancy work to avoid heavy lifting, late nights, poisonous fumes, dangerous tools etc, but I do enjoy those things.
