99.9% uptime still allows almost 9 hours of downtime a year. What matters is what the fleet does in those hours and in the minute after: broker restarts, reconnect storms, backoff with jitter, offline behaviour and fleet-level alerts.
In a dual-brain design, ESD pushed three GPIO mode lines high at once, the MCU read 111 and switched modes on its own. Why that fails criterion B, and the firmware fix.
Between the first prototype and production tooling, silicone casting can give you a small, presentable batch. When it pays off, where it stops, and what cast parts cannot prove.
After a year of memory shortages, one question tells you more about a part than its datasheet: if I design it in today, can I still buy it in 2031? Five follow-ups to ask at electronica.
We moved the LaMetric IoT platform from DigitalOcean to Hetzner without taking the fleet offline. What a live backend move needs, and how it went.
Attackers set supermarket freezers to 50 °C through refrigeration controllers reachable from the internet. Three weak points most connected devices share, four design rules that close them, and what the CRA now requires.
Most connected devices fail certification on the first PCB layout, not in the lab. Five decisions to make early, a pre-scan rule, and the RED cybersecurity rules since August 2025.
Most mechanical questions are answered faster by printing the next prototype. A few are not. When FEA earns its time, when a print is cheaper, and how FEA saved 5 to 10 prototype rounds on LaMetric SKY.
Reports say some cheap phones now ship with RAM taken from scrapped ones. The DRAM shortage behind it is real. Here is how used memory gets into a product, and four checks that stop it.
A study presented in October 2026 found 8,547 control systems at European solar and wind parks reachable from the internet. Operators can’t always secure the site network; manufacturers can make it matter less.
