To see what you can do with these sensors, check out these videos.
Silicone embedding is the trickiest part of the process of building your own muscle sounds sensor. This is why I chose to make this a completely separate instructable. This instructable will definitely test your patience and manual ability, so be prepared to screw up a couple boards before you get the hang of it.
So without further delay... let's get started!
Step 1: Complete part one of the instructable
Step 2: Bill of materials
Part: Nylamid spacer (Diam: 13mm, Thick: 2mm)
Qty: 1 per sensor (reusable)
Part: 20A Shore RTV Silicone
Qty: ~2g per sensor
Part: 65A Shore RTV Silicone
Qty: <1g per sensor
Part: Acrylic (transparent plastic) board with circular indentations
Specs: 25mm minimum width and length
Centered indentation depth: 0.4 - 0.6mm
Centered indentation diameter: 4 - 6mm
Additional indentations at a minimum 30mm distance in any direction
