Alternatives to the Raspberry

By admin

In today’s post we are going to see how to give an old computer a new life. This will allow us, for example, to turn it into a real cheap alternative to the Raspberry Pi, but it will also be a good complement to be able to use it as a navigation plotter on the boat, or as Radar for boats and airplanes, in the style of the ones we saw with the mobile in episode 46. A real way to recover an old computer and give it new uses, which will also be the base (either this or the Raspberry Pi or the Orange Pi, or the Banana Pi or the RPi CM4, etc..) for a lot of very interesting projects that we will see in the next episodes.. (Including receiving satellite images)
