Phil spent years groveling in mud trying to map caves. He shows you how he found a better way, using open source software and electronics!
Join Phil, an avid caver, as he recounts his journey of creating a cutting-edge cave surveying tool. Reflecting on his experiences in the 1990s, where primitive equipment like mechanical compasses and cumbersome tape measures hindered exploration efforts, Phil recognized the need for a more effective solution!

![Building “Dröne”: A Capacitive Synth That Uses Your Body as Part of the Circuit
Clem (@MAYERMAKES) takes inspiration from Tom Morello of Rage Against the Machine to build Dröne, a DIY body-controlled synth that recreates Morello’s famous “cable tip” sound. By using his body as part of the circuit, Clem explores how capacitance and inductance can create controllable, evolving tones. What starts as an experiment becomes a playable instrument that reacts to touch, proximity, and movement, even burning out a vintage speaker in the process. Watch how Clem turns a strange guitar trick into a full-blown electronic music project! https://bit.ly/43ccpar

![Add a Multicolor Filament Changer to Any 3D Printer | Open Source Solution
Clem rebuilds the 3D Chameleon MK4 from the ground up, replacing the legacy electronics with a modern ATtiny3226 controller, TMC2209 drivers, thermistor-controlled cooling, and clearer status indicators. The mechanical system stays true to the original open-source design, but the updated hardware is easier to assemble, easier to source, and designed for reliable multicolor filament changes without modifying your printer’s firmware.
