The Simple Scalar Network Analyzer

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 frequency of 35 MHz, the generated signal has a lot of harmonics and its a fairl ...

Wireless notice board using Arduino and GSM

Everyone would have known the use of notice board around our daily life. Even it plays a vital role in public places like bus stops, railway station and hospitals. But with a great shift in technology we could revolutionize this kind of notice board by taking it wireless. So that’s what this Wireless notice board Arduino project is all about.   EXISTING SYSTEM: In the present scenario to display any message ...

Capacitance Meter

Capacitors are vital components in electronics, but sometimes they are broken, or the value printed on the cap has become unreadable. Because my multi-meter does not have a capacitance measurement, I decided to make one! The principle of measuring capacitance is quite simple. The voltage of a capacitor charging through a resistor increases with time T. The time it takes to reach a certain voltage, is relate ...

Energy-harvesting power management ICs for wireless sensor nodes

Cypress Semiconductor has introduced what it believes to be the lowest-available-power PMICs that enable an integrated module size of 1 cm² for solar-powered wireless sensor node (WSN) designs. Intended to manage solar-powered wireless sensors for Internet of Things (IoT) applications, these parts are said to be the lowest-power, single-chip Energy Harvesting PMICs, and can be used with solar cells as small ...

Are My Documents Safe in the Root Cellar at

There is a large cellar where I could store unused items and documents, but the catch is the humidity there. It is a root cellar near a small brook and the humidity varies between 75% up to 90%. Archived material should never be exposed to humidity greater than 65%, therefore I have to isolate all documents in boxes from the air of the cellar. But are this boxes safe? Do they keep the humidity away from the ...

IQ Alarm clock using Arduino for heavy sleepers

Raising from bed can be the most painful thing you could ever do. We often set alarms to wake up but ends up in snoozing it out or even kick the alarms away. To address this we have come up with an Arduino project ” IQ alarm clock ” which will annoy you until you wake up. The most highlighting thing about this alarm is that it will ask you a question once it starts sounding and you can turn it off only if y ...
