Starting Development of the V2 Prototype Box

May 21, 2026

This week we started the development of our V2 prototype box.

After validating the first prototype systems individually, we are now moving towards a more integrated and robust enclosure designed to support all subsystems in a single, reliable unit. The goal of V2 is not just improvement in form factor, but a major step forward in stability, usability, and long term testing capability.

Testing at the CTN — Radioactive Materials, Soldering on the Spot, and a Better Signal

May 20, 2026

This week we returned to the Campus Tecnológico e Nuclear at IST to put CosmoMeter’s first prototype to the test. It was one of the most productive afternoons of the project so far.

Prototype V1 — It's Real

May 19, 2026

It’s done. CosmoMeter’s first prototype is complete.

The 3D printed enclosure came out, everything fit together, and we now have a fully assembled first version of the device in our hands. From breadboard to perfboard to a boxed, physical prototype — it’s been a long road to get here, but seeing it come together as a real object makes it all worth it.

First Prototype Enclosure — Designed in OnShape

May 18, 2026

With the electronics taking shape, it was time to think about how it all gets packaged. This week we completed the first design of the CosmoMeter prototype enclosure.

From Breadboard to Perfboard — Keeping It Compact

May 16 2026

With the circuit validated, it was time to move everything from the breadboard to a perfboard and build something more permanent.

Detecting Radiation Pulses - Oscilloscope Success

May 15, 2026

We reached another important milestone this week, we successfully detected the Geiger tube pulses on the oscilloscope and connected the ESP32 to start collecting them.
