10 Things CEOs Need to Know About Design slide set has many good points. It is a very good presentation on designing for the user experience. Take the inspiration from the slides. →
My Time Domain Reflectometer (TDR) circuit is now available in kit form. Far Circuits has made a TDR kit that consists of circuit board and components. The Far Circuits version is a slightly modified circuits, the modification is that the circuit board has a 5V regulator IC in it. With that regulator the circuit power →
I has been very hot and dry in Finland. Some kind of irrigation system or manual irrigation seems to be necessary to keep the plants happy. Livehacker reports on an interesting Build an Arduino-Powered, Tweeting, Self-Watering Garden System. It’s extremely simple. And, not only will the Arduino water the soil when it starts to get →
Chipshow’s LED tube page gives some views what LED tubes look like. As you can see there are many LEDs inside a LED tube. The most economical way to run sich LEDs from mains power is to connect many LEDs in series and then use some current limiting circuit to set the drive current right →
The idea if replacing fluorescent light bulbs with LEDs seems to become popular. There are different kind of products made for that purpose. LED bulbs utilizes large arrays of high power LEDs to provide up to provide light. They are at best an economical way to replace commonly used fluorescent tubes. Since introducing LED based →
