The Evolution of Our Smart LED Lamp

Product development is iteration. Our smart LED lamp has been through several major design revisions — each one informed by testing, thermal analysis, and manufacturing constraints. Here’s a look at how the design evolved.

Infineon and Arrow Thailand Visit Our R&D Lab

Today we had the pleasure of welcoming visitors from Infineon and Arrow Thailand to our R&D facility in Chiang Mai. Nathee from Infineon joined us alongside Buncha and Narin from Arrow Thailand for an afternoon at our lab.

Reverse-Engineering Our Spectrophotometer with Claude

Our integrating sphere — the HPCS 6500 spectrophotometer — is a critical piece of equipment for LED development. It measures everything we need: luminous flux, color temperature (CCT), color rendering index (CRI), chromaticity coordinates, full spectrum analysis from 380–1050nm, and electrical parameters like power, power factor, and harmonics.

How We Track 290,000 Components with InvenTree

When you’re doing electronics R&D and small-scale manufacturing, knowing exactly what you have and where it is matters. A missing reel of 0402 capacitors or an out-of-stock GaN FET can stall a prototype run for days. So we built a proper inventory system early.

Our Automated Test Bench is Live

One of the biggest bottlenecks in power electronics R&D is testing. Manually sweeping through voltage and current setpoints, recording readings, and calculating efficiency at each operating point is slow, error-prone, and mind-numbing. So we automated it.

Meeting with German Honorary Consul Sebastian-Justus Schmidt

On March 5th, we had the honor of welcoming Sebastian-Justus Schmidt, the German Honorary Consul of Chiang Mai, to our R&D facility on Wualai Road.

When the Ping River Came to Our Lab

In the first week of October 2024, the Ping River peaked at 5.3 meters at Nawarat Bridge — 1.6 meters above the 3.7-meter overflow threshold. Chiang Mai flooded. Our interim lab took it hard.
