Scientists have come up with a way of creating sensors which could allow machines to smell more accurately than humans. Every odour has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are mirror […]

This project was built to monitor the temperature of one of our computer rooms at work that has rather temperamental air-conditioning. The maximum temperature can be set, and if this is exceeded an alarm is activated.The unit gives a continuous display of current temperature and it’s possible for the constructor to change the device program

Universal multimeter UT139C with a high resolution will be appreciated at development and everywhere, where you need to find out a situation in a given device accurately Imagine a situation, when you need to check or set a voltage of 3.3V or 5V usual at digital electronics (AD converters reference,…). Or to measure the end
With the UT139C you´ll find out why 5999 is better than 1999 … Read More »
After participating to Codemotion Rome last month, from the 9th of May we’ll be spending a couple of days at Codemotion Berlin, an innovative tech event engaging developers of all languages and technologies. We’re having an Arduino wearables workshop organized together with Kobakant duo (Mika Satomi and Hannah Perner-Wilson) and focused on the use of Lilypad. In

High-precision air quality monitors are normally very expensive, but Tim Dye of Sonoma Technology is on a mission to change that. He’s been working with Michael Heimbinder and habitatmap.org to create a low-cost sensor system that when designed properly and integrated into a software platforms can provide valid data. AirCasting is a platform for recording, mapping,

Monitoring is the key to unlocking the energy production of the solar cell. It is easy to lose efficiency through the use of circuit architectures that assume constant energy production when the solar environment is constantly changing. The change in current-voltage properties as a solar module heats up or receives more light can be an

Today’s post is something I’ve prepared for a long time. Hardware-wise it’s a simple thing – ATtiny45 emulating a PS/2 device, sending a keypress when three knocks are detected in the attached piezoelectric sensor (or piezo buzzer as they are also called). But if your computer can boot on PS/2 keyboard input and you have

PUB! is a Programmable USB Button on which you can program a sequence of keystrokes. When you press the button those keystrokes are “replayed” over a USB connection. The button (which is really a rotary encoder with a built-in push button switch) is programmed using an innovative and slightly quirky interface that does not require

Ventilation, air conditioning (HVAC), or any other applications, where a pressure or a flow of air (gas) is essential, can be precisely regulated only if we know a real pressure/ flow conditions. Monitoring of fans functionality, status of filters, …, even for this purpose are very suitable differential pressure sensors from Swiss company Sensirion with
Sensirion SDP sensors measure pressure but even a flow Read More »
Abstract: This design idea presents an integrated IF voltage-controlled oscillator (VCO) that can retransmit the audio signal from a cell phone to the FM broadcast band. By placing the cell phone’s speaker near the microphone, the user can use the phone as a hands-free device while driving. The circuit in Figure 1 can retransmit the audio
