Trend price : DIY
Popular little DIY originally based on a single IC timer 555, the first project was found on a radio Shack book written by Forrest M. Mims III named the "Stepped Tone Generator"
Overview
layout depends on what you want to build: plastic box, tin can, wood case or other recycled stuff... it is up to you. Main panel features 8 knobs and 4 lever switches for sequencer, no display nor Midi fancy stuff, just a single switch that enable or disable the noises.
Voice
this noisebox uses a dual 556 and it generates a single voice based on a pulse waveform with variable width. If you're into 8-bits stuff this will sound sweet to your ears.
Sound
the first 2 knobs on upper row controls the pitch and pulse width, while the third one changes the sequencer frequency.
Sequencer
4 levers activate or deactivate the relative note triggers and each pitch is changed using the four red knobs on lower row

OK: bleep / cheap
NOT : bleep!
"cheap and fun to build! of course you to have to love those bleeps and other 8bits noises from the past."
