We have often commented that we’re a bit tired of hearing random notes when someone sends us a musical project. We love home made instruments, circuit bending, and creative sound, we just like some intentional direction to the noise. This just might be an exception to the rule. This typewriter plays random notes as you type. While it might annoy your cohabitants into a violent rage, it seems oddly cathartic. We have heard people talk about the pleasure of hearing the keys clack as they type. It just seems like you would get used to this and find it just as pleasurable. Maybe we’re crazy. Unfortunately, they don’t divulge any technical details, but we can imagine a simple way of wiring directly into a cheap keyboard to get the same effect.
This is an interesting instrument. Part laser harp, part guitar, the Prism seems to have some potential. [Jeff-o] put some major time and effort into refinishing a guitar, building the circuit and putting it all together. He did a great job, the instrument looks fantastic and appears to work. We do have a request though; please post a video of it being played as an instrument. So many of these electronic instrument projects just spit out random noises. While we understand that some people are into that, we would love to hear some control. How about intentionally changing notes to make a melody? Based on the description, it should have control for pitch, and even speed of the oscillation. So let’s hear some music. We don’t care if you’re any good, just please play some music with it. If you would like to build your own, he has the schematics and PCB layout available for download.
