With an enhanced offer of X-chip series USB chips, it´s possible to immediately choose a type suitable for your application. The family of X-Chip series USB chips we introduced to you in the article „New X-chip series will connect you to USB even easier and faster!“. Gradually these USB chips gain still more popularity thanks …
If you’ve ever been designing a circuit and had to experiment with different values of caps and resistors, you probably didn’t like it much. It can be a hassle to switch out components over and over, trying to find the right combination to suit your needs. With RC filter circuits, it can be quite difficult …
I have something with the weather. I always like to know how warm or cold it is, how much rain has fallen, how hard the wind blows and from what direction,… and so there are lots of sensors around our house to keep me up to date. These sensors give only a limited range of …
This little device shows you the CPU-load, how much physical and virtual memory is used. It shows this data per 10% on 3 led bars. To do so it uses a VCP (Virtual COM Port), so that it can be connected to a PC via a USB connection to receive the data. Collecting the data …
This project is named “Engadino” after Engadin – ski resort in Switzerland. The reason for this is that I live in Switzerland, I like skiing and the name is easy to remember and pronounce. By itself the project is a clone of “Pinguino“. “Pin guano is an Arduino-like electronics prototyping platform. It supports different 8- and 32-bit …
What follows are instructions for constructing a battery powered portable VU meter, as well as detailed instructions for the construction of the PCB needed to complete this project. It was designed to illuminate from 0-10 LEDs depending on ambient sound levels. I designed it to be attached to a wristband, clothing, or a necklace if …
My obsession of this year is full-color LED. I have made Aurora 9×18 as a result. As much as I love the scale of Aurora 9×18, I also wanted to have something smaller, perhaps something that can go on a costume. Here’s Aurora mini 18. It has 18 full-color/RGB LEDs on a smallest possible circle. With …
One of the biggest challenges faced by solid-state lighting designers is reliability. Electrical and thermal conditions are two major factors affecting device life and lighting output and, while long life is a key benefit of LEDs compared to incandescent and fluorescent light sources, all bets are off if the LEDs exceed their temperature ratings. Thermal …
This article describes the development of touch sensing and switching techniques capacitive sensing technology. Products cited include both stand-alone capacitive sensing controller ICs and microcontrollers (MCUs) that include touch sensing as a peripheral function. Capacitive touch sensing has experienced explosive growth to become the default human interface for several classes of consumer product. Users of …

If you like this instruct able, please vote for it! For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There’s a couple of commercial products that can do this, but not with the flexibility I wanted. I designed a Arduino micro-controller based …
