Training

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.

How to make a multitouch device.

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...).

-Tbeta software.
