Review: PCB Fab House PCBWay

Introduction

A while back I got an offer from PCBWay to test their PB prototyping services. As I was at the time designing a couple of new circuits I accepted their offer and below I will give a description of the process and my impressions.


I like blue silk screens..

This tiny board is white to maximize light reflection. See the previous article for details.

For the test run I used two designs, one that was featured in my last article, and one that is coming up soon.

Disclaimer: I have received these PCBs from PCBWay for review.

Broadlink Smart Bulb Conversion to Open Source

Introduction

Recently I have come across some smart LED light bulbs that came in different sizes, shapes, functionalities and manufacturers. One thing they share is that they all do their "smarts" over a WiFi connection for which you need to use a smartphone and one of the many apps that help you set up the bulb. Unfortunately, this poses the same serious privacy issue (as I have already shown in a previous article) as for the apps (and the light bulb) to work properly you not only have to be connected to the internet at all times, but you also have to provide sensitive personal data (like your home WiFi network's name, password, your location, etc.) to a 3rd party you know nothing about.

This particular bulb is marketed as "LED Light Bulb" requiring the "Magic Home-Smart home" app for your smart phone.
