The physics of GPS
Published: April 13, 2026, 4:08 pm
Shri Khalpada writes about the physics of GPS for PerThirtySix: GPS is fundamentally a translation tool: it converts time into distance. A satellite sends a signal, your phone catches it, and the delay between those two events tells the phone exactly how far away the satellite is. Everything else is about making that measurement precise […]
Air powered segment display: 3D printed microfluidic RAM
Published: April 13, 2026, 3:59 pm
soiboi studio presents an air powered, 4-digit, 7-segment display. I’m using microfluidic logic, silicone membranes, and air pressure to create a display that doesn’t just show the time, it “remembers” it. By integrating vacuum-powered transistors into a 3D-print, I’ve accidentally created a pneumatic RAM (Random Access Memory). Unlike electronic displays that rely on high-speed flickering, […]
