I was recently asked to provide a video projection for the Proteus Gowanus ball, and assembled my most compact, self-contained projector rig to date. It involves Velcroing a Raspberry Pi computer to my homemade projector mount, which can be clamped anywhere with standard film grip gear. When plugged in, 1080p video plays in a loop. The projector is small but bright, a 3,000 lumen Optoma TW-1692.
Getting the video to start and loop automatically was fairly simple, but required several stops on the internet…
…I loaded the video onto the device, strapped everything together — projector, mount, Raspberry Pi (in a Pibow Timber case), multiplug, USB power adapter, HDMI cable, safety cable, extension cord — plugged it in, and it ran. Just like that.
Adafruit’s Raspberry Pi Lesson 6. Using SSH: In this lesson you will learn how to remote control your Raspberry Pi over your local network using Secure Shell (SSH). A common reason for remote controlling your Pi from another computer is that you may be using your Pi solely to control some electronics and therefore not need a keyboard, mouse and monitor, other than for setting it up. It also can just save on desktop clutter, and the problem of having multiple keyboards and mice all over the place. (read more)
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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
