Powering the Raspberry Pi from standard RC batteries #piday #raspberrypi @Raspberry_Pi
Tutorial and pointers for powering a RasPi using a standard RC battery, from Patrick Skillen:
The Raspberry Pi is a fantastically versatile, cheap and tiny computer. It’s very easily comparable to the ever popular Arduino, except that it provides significantly more processing power and programming options. One of the major drawbacks to this power, however, is the increased power consumption which makes powering the device problematic.
For example, a standard Arduino Uno requires mere tens of milliamps (mA) to function at full power (nanoamps in sleep mode), while the RPi is rated at 700mA. This means it can’t technically be powered from a standard USB port because USB 1.0, 1.1 and 2.0 permit a maximum power draw of 500mA.
You need a wall adapter to supply that 700mA, or more with peripherals such as wifi. The idea if powering it off a small lithium-ion battery or standard AAs is completely out the window.
One field which is particularly experienced at supplying huge amounts of electrical power is the field of remote control (cars,boats, airplanes, flying blimps with faces on them [LINK]). All of the batteries and technologies we need already exist, we just need a way to join the two in the middle.
Enter the lithium polymer (LiPo) battery, and the ironically named Battery Eliminating Circuit (BEC)!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
