Recently, I reviewed the JustBoom AmpHAT and found it to be an excellent piece of kit for those that like their audio ‘just right’. Well, now it’s little brother, the Amp Zero pHAT has been used in a project that looks really lovely. Frederick Vandenbosch has taken the pHAT, a Raspberry Pi Zero, a speaker, and a Pimoroni Scroll pHAT and created a beautiful ‘spiral speaker’ with built-in spectrum display. He’s written the whole thing up as a tutorial and it’s been posted on the Pi Supply blog here. You can view a speeded-up video of the build below. You can get hold of the Amp Zero pHAT here.
