ack in the scene is F00 with a new improved VU Meter mod, and should you want to take on this mod yourself, kits are available over at Tailor Made Toys. Got a few extra bucks? The F00 will mod it for you. Details here.
Revision 3 has been totally digitized using a PICAXE-28×1 that replaces the quad opamp found in earlier versions. That comes with good reason as the opamp version suffered a decrease in LED brightness as the level rose. Nothing major but for any perfectionist you understand. There are other benefits by going digital too: each LED can be individually controlled now; you’ll notice LED-animated transitions between modes. There is also a “sleep” animation that’s triggered when things remain silent. Pretty cool! Nice work F00.
