Old speakers...

I found some old speaker.
What can I do with them?
I have a new idea, let's see if I can develop it!

The old idea was to use the Pringles tube, but is very very unoriginal and Pringles still do it (damn!).

I think this idea is old and was still invented by other users...

If you have ideas...write them as a comment.
PS: they work.

3D Printers, how do they work? (like magnets?)

Take a look at this video:

I am a bit surprised how it detect moving parts scanning the tool.


In the near future where the prices will be lower and the distribution will be for regular customers ... what will you create?

I have some ideas ...

Waiting for these products become widely deployed, you can build one:

DIY: 6$ mouse pen

Yesterday I was a bit bored so I tried to build something.

With a old yellow marker and a bit of glue I made this mouse pen.

The internal circuit is from a "finger mouse" (see related post) and it's set to stay inside the marker.

Does it work fine? Not bad, lol, but this optical sensor doesn't work too much fine on the surface of my desk so I tried on a mousepad.
