The guitar tuner its alive, it just needs some tweeks in the software ( quite a lot ), but i looks pretty good when its power on.


And if you havent noted it has the energy harvest connector on a side :P

Guitar Tuner PCB

The guitar tuner PCB is ready to get manufactured!


I have send all the gerber files to PCB Fabrication, so here there also if you want to make one of your own, this Open Hardware, so you can downloaded and used as you prefer to.

This PCB contains as said in previous posts a Microphone amplifier, a bunch of LEDs as user inteface, i have added 3 buttons if needed, it has a 3v rechargable battery socket and a connector for an external battery.

I think its important to say that this design uses de reverse mount LEDs of Wurth, I have never use those LEDs so i hope they look awsome in this design as it will be part of the front plate of this device.


I use Autodesk eagle in all my designs so you may download them an used with a free version of eagle if you want.
