Tagtool

From Andy Woods, who built himself a real beauty of a Tagtool Mini:

I am an artist living in East Tennessee, in the US. I just wanted to thank you for making the tagtool open source and enabling people like me to take art to new levels and places. Using your tutorials I was able to build a Tagtool of my own an I have attached a couple of photos of it.
Before this project I had ZERO electronics experience, but because of your inspiration I have learned a lot. Thank You!
