Procrastination is a specialty of mine but after Dr Blankenstein expressed an interest in what I was going to do with his work, I felt obligated to get onto it.
Previously I mentioned plans to install the Illumiringer into a Speak And Spell but I opted to make it a stand-alone effect once I realised it'd be a squeeze to fit the 9V battery into the device. After a bit of hunting around I settled on this plastic specs case to ensure I didn't short circuit anything by using a metal tin.
The effect does control pitch, haven't noticed much character yet so I'll give it a go on my voice sometime.
