We have many options for this. It would be enough to use a portable battery to power the Raspberry Pi, since we only need a USB power source to work. However, these portable batteries tend to be big, heavy, and uncomfortable to wear in conjunction with the Raspberry Pi as they do not fit their size properly, and there is no way to & # 39;
Things are changing with the Gumstix Battery IMU
Only two AA-size batteries will need to use this Raspberry Pi "dock" that will allow us to use it for hours and hours (because it consumes very little), and which comes with non-chargeable batteries that we can recharge by simply connecting the Raspberry Pi to its standard USB connector.
This board connects to the Raspberry Pi through a standard 40 port, and also adds functionality that the device itself does not have, something as basic as a power button (which in this case is not a button but rather a switch). So far, just plug Raspberry into the power source and turn it on automatically, but with this add-on we can either open it or start as we like.
The Gumstix board also features a Bosch MBI160 module that includes a 3-axis accelerometer and a 3-axis gyroscope for navigation, which can also allow us to create our own drones with whatever we can think of.
This device can be purchased for $ 50 on the author's website.
How to make the Raspberry Pi completely wireless
We've already figured out how to add a battery to a device to have its own operating independence, but logically we'll need some things to make it completely wireless, right?
As you can see in the video above, you can use raspberry independently and wirelessly. Or we can add a WiFi module
On the Gumstix Github page you can even find the source code for the demo we have placed above the video.
We can also have portable monitor and, in conjunction with Raspberry with this "battery", we can use it to watch series and movies anywhere by connecting the screen to the device via HDMI cable. The possibilities in any case are very wide and, with the Raspberry Wireless, the limit is on everyone's imagination.
