Android devices can be used as signal generators and signal analyzers. It is easy when all you want is to get the signal out of the speaker or headphone connector, and you are happy to analyze what internal microphone in the device receives. But what if you want to feed some external signal into your →
I have posted some teardowns of serveral electronics devices and have some notes on their electrical safety. Examples of ones with questionable safety were this is tiny USB charger and this USB charger. The later USB charger posting has also example of power supply that seems to have properly built safety in it. But how →

USB Type-C Connector is on the news today as they have introduced another new type of USB connector that is not directly compatible with any existing connectors. USB Type-C Connector Specifications Finalized article tells that today the USB-IF (USB Implementers Forum) announced that the latest USB connector which we first caught a glimpse of in →
Interfacing digital electronics to analog world is needed in many applications. There have been several attempts at devices that might be called field-programmable analog arrays (FPAAs) over the years, but most have failed to establish a significant market presence (maybe except Cypress Semiconductor PSoC). The Analog Swiss Army Knife article tells that without a proper →
