8 Bit Violin
Ranjit Bhatnagar’s violin may be 8 bit, but one can coax uncompressed, analog music off its strings.
Snip from the description:
A working violin made from maple and oak craft wood. The design is all 90 degree angles except the fingerboard. The tuning pegs are literally square pegs in round holes. The thing’s tuned two half-steps low until it gets used to the tension.
