Control the Unicorn HAT with the Skywriter HAT on the Raspberry Pi

by  •  • 1 Comment

I’ve been playing around with a recently-purchased Unicorn HAT and I was just wondering if it was possible to do this! Lo-and-behold this blog post came up in a general search for Unicorn HAT stuff. Sandy MacDonald has used a pair of Black HAT Hack3r boards to allow him to daisy-chain the two HATs. A little bit of Gaussian programming later and he now has a fascinating little display that reacts to movement above the Skywriter. Read how he did it here. He’s also done a tutorial on using the Skywriter as a colour control for the Unicorn. You can find that here.

Hackaday.io user Chewable Drapery (Dean Walker)’s grandfather-in-law is 92 and is gradually losing his sight. In particular, he has real problems reading the on-screen television guide. So, Chewable has constructed a box and a controller, called EVA, using a Raspberry Pi that downloads the TV schedule from an internet API and then reads it aloud via Google Translate. You can read how he did it here and see a video walk-around of the project below:

RealVNC and the Raspberry Pi

by  •  • 2 Comments

As announced at the Big Birthday Party, RealVNC is now available for the Raspberry Pi. The software allows you to remotely connect to the desktop of the Pi via a remote PC, Mac, Linux box, Android, iOS or Chrome device. There’s even a free version, although the paid-for version has some rather nice extras like encryption. Read more about the capabilities of the different licences here and read about how to install it here.
