Arduino and SP0256A-AL2
This is part 6 in a series of blog posts in which Kevin makes a vintage speech synth chip sing!
He initially wanted to play with the speech but then discovered that he could vary the speech-chip's clock programatically to make it sing musical notes.
In this most recent instalment he's hooked up a MIDI keyboard to make the speech chip sing Do, Re Mi etc as appropriate. He comments that it's not as responsive as he'd hoped and has a limited musical range, but it's a fun experiment.

I built a reverb tank out of an old lamp
On my very long to-do list is building a plate reverb. It may not happen due to space, but you don't need a massive slab of steel to create an interesting reverb. David Hilowitz has used a discarded angle-poise lamp which has some interesting properties thanks to its springs. He also coaxed some interesting sounds from bowing, stroking and striking the lamp.

How to build your first (good!) contact microphone
It's well known that a piezo disc can be attached to any surface and act as a microphone, but I learned from this tutorial how to wire two to make a balanced microphone with a stronger output. I was also inspired by the number of interesting places that The Sound of Machines found to record interesting sounds.
Sound chips and retrocomputing

The Coral Caves of Illusion
Paul Duffy of The Coral has reworked their entire debut album in 8-bit style and it sounds amazing. The album is called The Coral Caves Of Illusion and it's available for streaming on Spotify here.
Paul used miniBit platform and was inspired by Megadrive games such as Sonic and Castle of Illusion.

Blockenspiel / Xylophone - Functional and Playable
The Blockenspiel is a xylopyone which is entirely made of lego - even the beaters. It sounds surprisingly good.
It was designed by Zung92 and appears on Lego Ideas, where you can create an account if you don't have one and give the idea a vote.
