The one I’m presenting here is a little over the top(!) – you can build an equivalent much simpler and cheaper – but this one’s for me, and I like making things! Fundamentally, what I ‘m building…

They are pretty solid and can easily move from work bench to the floor for testing – especially with the onboard battery. The PCB ensures a solid connection to route power and audio…
