Here is a montage of photos that I took while modifying my iPhone 4s to build in wireless charging. There are wireless charging options out there such as the powermat system but they all involve slipping on a jacket around the iPhone. I wanted to internalize the technology so that the beauty of the iPhone is not hidden away! It’s taken a while to complete but it’s finally done.

Ante Vukorepa draws our attention to this video of Claude Paillard, a French radio amateur (F2FO), making his own tubes (also known as thermionic valves) from scratch. “The video depicts the whole process, from winding the filament through making the glassware, assembly and vacuuming, to testing. Pretty awesome!”
For more information on Claude’s activities as well as links to articles on vintage radio topics, go to Claude’s website. (In French; if English is needed, click on the Google translate link at the top of Claude’s webpage.)

In everything we do we try to be different. Our Christmas greeting is this year more personal, faster, more mobile, louder and environmentally friendly …
When we reflect on this year’s greeting, we wanted to do it otherwise. What is typical for us, so we try to diversify it from other distributors? Certainly it is also our personal relationship with you. Into everything we do, we try to put a personal approach. Indeed, it is not just about the components, but also about people.
Therefore, we also wanted with this Christmas greetings to get closer to you. Although it is not in our power to visit each of you personally before Christmas, we use available technology to be at least close to it.
And he’s still a positive. Our greeting is environmentally friendly, because we save a few trees produce CO2 eliminated in connection with distribution of paper greeting …
And here is our Christmas video greetings for you … we are an international company so our greeting is also in the foreign languages
