Music Box Plays “Still Alive” Thanks to Automated Hole Puncher

Most projects have one or two significant aspects in which custom work or clever execution is showcased, but this Music Box Hole Punching Machine by [Josh Sheldon] and his roommate [Matt] is a delight on many levels. Not only was custom hardware made to automate punching holes in long spools of paper for feeding through a music box, but a software front end to process MIDI files means that in a way, this project is really a MIDI-to-hand-cranked-music-box converter. What a time to be alive.

The hole punch is an entirely custom-made assembly, and as [Josh] observes, making a reliable …read more

Neural Network Composes Music; Says “I’ll be Bach”

[carykh] took a dive into neural networks, training a computer to replicate Baroque music. The results are as interesting as the process he used. Instead of feeding Shakespeare (for example) to a neural network and marveling at how Shakespeare-y the text output looks, the process converts Bach’s music into a text format and feeds that to the neural network. There is one character for each key on the piano, making for an 88 character alphabet used during the training. The neural net then runs wild and the results are turned back to audio to see (or hear as it were) …read more

Enter the Space Tunnel

What’s better than 1 string of LED lights? 96. That’s how many. Each string of the 96 has 60 ws2812b LEDs, for a total of 5760 individually addressable RGB LEDs.  That’s not the cool part of [jaymeekae]’s Space Tunnel installation, the cool part is that they’re interactive.

Starting out with some PVC piping, dark cloth was used as a backdrop and the LED strips were attached to it. Several power supplies are used to supply the voltage necessary and each strip controlled by FadeCandy chips which connect to, in this case, a Windows PC via USB. Initially, computer power supplies …read more
