Fans of HiFi sound and similar „audiophils“ usually don´t cover their loudspakers and surely not their membranes. Firstly, to cover a beautiful top-class loudspeaker is almost a sin 🙂 and naturally all that stands in a way of sound usually influences it in a negative way. However, totally different situation is in traffic, audio bells, […]

One important parameter in embedded system designing is power consumption. This parameter is directly related to the battery lifetime, if the system is to be powered from a battery. In order to determine the power rating of your designed system, you need to know how much current the system draws from the source at a […]

Its lifetime may not be quite over yet, but the humble television is facing some stiff competition from the computer, as the entertainment portal of choice. Widespread access to superfast broadband means that users are now able to stream films and television shows, download music and of course browse the net 24/7, from wherever they […]

This project introduces the use of PCA9550, an LED driver that causes the 2 LEDs to ON/OFF or in a flashing state at programmable rate. It has 2 selectable, fully programmable blink rates between 0.172Hz and 44Hz or 5.82 seconds and 0.023 second respectively. Its internal oscillator does not require external components and I2c bus […]

Several previously published Design Ideas and appnotes [1-4] show how to use many pushbuttons with a minimum number of inputs. They require an RC circuit where the timing can be measured to identify which pushbutton has been pressed, or an ADC input, with resistors forming a divider for each pushbutton pressed. The following Design Idea […]

Do you like tools usable for several jobs? Gas soldering tool Dremel VersaTip 2000 in a “Decorating kit” edition certainly belongs to such record breakers in the versatility of usage. Multifunctional gas tool Dremel VersaTip 2000 usable for technical but also creative works was introduced to you in our articles. Soldering, melting, hot-cutting, welding and […]

We normally use a simple static LED display screen to convey a message. Earlier, when we want to display large data, we used to change message for every few instances. Now scrolling displays are more preferred to static. By using a pre programmed controller, we can make LED display in scrolling way. We can also […]

When we speak about “versions” – in case of EADOG from company Electronic Assembly it means a lot of “glass” types (STM, FSTN, transflective,…) and what is unique – many s display + backlight combinations. Right thanks to this unique possibility to make your own combination display + backlight according to your needs make the […]

MinieC eC interface is a very cost effective solution for adding eC sensing capability to any project. This unit takes the analog complexity out of measuring the conductivity of a solution. While working with Peter from ManyLabs/WireGarden, we wanted to begin to create a system of open source water quality sensors that can be cheaply […]

Representatives from the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden will be showing off their Li-Fi wireless communication system at the upcoming electronica exhibition held in Munich from November 11 to 14. The system uses infra-red light as the transmission medium and can transfer data at a speed of up to 1 Gigabit per […]
