Monocle enables Alexa devices such as Echo Show/Spot & FireTV to view your network IP cameras & control them with a wireless PTZ controller. Story Amazon Alexa® (at least at the time of this writing) does not inherently support any direct integration with local/private network cameras running securely inside your network. Instead Alexa focuses on […]

4Duino Intelligent Buggy project demonstrate how does uCAM-II works. This project also utilized two 4duino communicating using Server-Client architecture over TCP. It also uses a buggy car which carry the 4duino server and uCAM-II. By using built-in ESP8266, 4duino client sends a request to 4duino server to move the buggy and capture photo via wireless

Creating a Local Network to share personnel and confidential data’s has become almost impossible for a common man in our modern world. This is mainly because all common chat methods like Whatsapp, Facebook, Hangout and almost everything involves an internet connection. What if, we could share data without the medium of Internet? How cool it

With a simple knowledge of Arduino and Voltage Divider Circuit, we can turn the Arduino into Digital Voltmeter and can measure the input voltage using Arduino and a 16×2 LCD display. Arduino has several analog input pins that connect to an Analog-to-Digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, means

Description The network analyzer shield uses an Analog Devices AD9851 DDS chip clocked at 180MHz which will output a sine wave at any frequency from 0Hz and 72MHz. The DDS output is filtered with a Butterworth LPF and then passed to a two transistor amplifier. The shield will output approximately 0dBm (maybe 1-2dBm if you

After playing around with the SynthNV signal generator/power detector discussed in the previous post I realized what a useful a tool it is for RF testing. While its a terrific tool for VHF/UHF/Microwave testing, the SynthNV has a couple of serious limitations for amateur use in the HF region – the signal generator has a minimum
