The modern keyboard enthusiast is blessed with innumerable choices when it comes to typing hardware. There are keyboards designed specifically for gaming, fast typing, ergonomics, and all manner of other criteria. [iot4c] undertook their own build for no other reason than nostalgia – which sounds plenty fun to us.
An Arduino Leonardo is pressed into service for this hack. With its USB HID capabilities, it’s perfectly suited for custom keyboard builds. It’s built into a working Atari 65XE computer, and connected to the keyboard matrix. The Keypad and Keyboard libraries are pressed into service to turn keypresses on the 80s keyboard into easily digseted USB data.
There’s plenty of room inside the computer for the added hardware, with the USB cable neatly sneaked out the rear. [iot4c] notes that everything still works and the added hardware does not cause any problems, as long as it’s not used as a computer and a keyboard at the same time.
It’s possible to do a similar hack on the Commodore 64, too. If you’re doing tricky keyboard builds yourself, you know where to send ’em.
I need circuit connection photos properly because tried so much but still my project is not working i dont know how to connect it properly
Students at the University of Illinois at Urbana-Champaign have a brain-computer interface that can measure brainwaves. What did they do with it? They gave it to Alma, a golden labrador, as you can see in the video below. The code and enough info to duplicate the electronics are on GitHub.
Of course, the dog doesn’t directly generate speech. Instead, the circuit watches her brainwaves via an Arduino and feeds the raw data to a Raspberry Pi. A machine learning algorithm determines Alma’s brainwave state and plays prerecorded audio expressing Alma’s thoughts.
Alma’s collar duplicates — to some degree — the fictional collar from the movie Up. Of course, Dug was a bit more loquacious. It isn’t very clear from the video how many states the program classifies. A quick peek at the code reveals five audio clips but only one appears to be wired to the recognizer — the one for a treat. We think it might be a harder problem to figure out when the dog does not want a treat.
Oh. By the way. Good dog! Very good dog!
