I got interested interested in ESP8266 WiFi module after reading New Chip Alert: The ESP8266 WiFi Module (It’s $5) article. Why is it cool? It’s a WiFi module with an SOC, making it somewhat similar to TI’s CC300. ESP8266 is an UART to WiFi module that you can pick for less than $5 USD. ESP8266 is →
USB to serial port adapters are gadgets that we have a love/hate relationship. We love that we can add serial port to a new PC, but we hate that many of those adapters do not feel reliable in use. Counterfeit copies of USB to serial ICs have caused headaches for users and manufacurers. And it →
Nowadays it is typical that small embedded platforms and modules offer TTL level (5V or 3.3V) serial port interfaces in them. The easiest way to interface such port to PC is to use USB to TTL level serial port converter (it is easier than adding external TTL-RS232 converter board and then connect to normal serial →
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 →
There are many initiatives to get people to know basics of programming. The current thinking seems to be that anybody can learn to code if concepts are introduced in the right way. Code.org‘s mission is to get coding into curriculums for students. It is known for example on projects like Computer Science Education Week and →

The reasons for interests are good specifications, based on open source hardware design and price is reasonable ($12.22 / 9.37 Euro). DIY Meter Tester Kit For Capacitance ESR Inductance →
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 →
