In order to carry out an invention or DIY projectWe will need to have some basic knowledge, which will be provided by the training The following is a list of the areas that will influence the invention. Before taking the risk of starting a project, it is best to have a good foundation of training through these articles.
Thanks to Migue, I find in FORAT this curious "gadget" for our computer. A thermometer that will help us to know that ambient temperature is inside our PC. Very well explained and step by step.
According to the author, the thermometer in question is from an old refrigerator, the sole purpose of which was to make a bulge. This thermometer measured the internal temperature of the fridge.

From LeeMiBlog, I find a very curious video for make your own multitouch step by step which will cost you between €3.5 and €35, depending on the materials you want to use. Yes, a bit rudimentary, but it works like a charm. But as it is clear, the secret lies in the software of recognition.
Materials:
-Cardboard box.
-Piece of something flat, rigid and transparent (glass, plexiglass, etc...).
-Paper (Folio paper, or any kind of paper).
-Webcam or video camera.
Computer (if it is a dual-core, the better, but it is not necessary).
-And optionally a photo frame.
-Tbeta software.

In this first special invention, I'll show you how to make a step-by-step metal detector like mine, I will try to make this post usable for all audiences, but it is inevitable that those who have no idea about electronics will not know anything about it. For those interested, it is not a 1000€ detector, it is a detector to entertain yourself building it, however it has nothing to envy to the most mediocre detectors (between 100 and 400€), I spent a total of about 50€, and it gave me enough to buy the materials. to make three detectorsIn addition, in our shop you have all the necessary components to make the board at the best possible price.
The detection depth is not bad either (this does not usually vary much between detectors), it is about 10cm with the smallest coins (1, 2 and 5 cents). So that you can start to get your teeth into it before you start:
