Dot matrix printers are the dinosaurs that won’t go extinct. They are not unlike a typewriter with the type bars behind the ink ribbon replaced by a row of metal pins controlled by solenoids, each pin being capable of printing a single pixel. At their best they could deliver a surprising level of quality, but their sound once heard is not forgotten, because it was extremely LOUD.
[Wpqrek] bought an old dot-matrix printer, a Commodore MPS 803. Sadly it didn’t live up to the dot-matrix reputation for reliability in that it didn’t work, some of its pins weren’t moving, so …read more
Sign language can like any language be difficult to learn if you’re not immersed in it, or at least learning from someone who is fluent. It’s not easy to know when you’re making minor mistakes or missing nuances. It’s a medium with its own unique issues when learning, so if you want to learn and don’t have access to someone who knows the language you might want to reach for the next best thing: a machine that can teach you.
This project comes from three of [Bruce Land]’s senior electrical and computer engineering students, [Alicia], [Raul], and [Kerry], as part …read more
People love their tech, and feel like something’s missing when it’s not there. This is the story of one person’s desire to have the venerable trackpoint in their new keyboard.
[Klapse] loves a Lenovo old-style non-chicklet keyboard, so, despite the cost, five were ordered. They very quickly ended up with keys that didn’t work, although the trackpoints still did. After buying a sixth which ended up the same, [Klapse] decided that maybe giving up on the Lenovo keyboards was the best idea. A quick stop at a local store scored a fill-in mechanical keyboard, but in the back of [klapse]’s …read more
It’s a fairly safe bet that a Venn diagram of Hackaday readers and those who closely follow the careers of YouTube megastars doesn’t have a whole lot of overlap, so you’re perhaps blissfully unaware of the man who calls himself PewDiePie. As such, you might not know that a battle between himself and another YouTube channel which uploads Bollywood music videos has reached such a fever pitch that his fans have resorted to guerrilla hacking to try to sway public opinion towards their side. It’s perhaps not the dystopian future we imagined, but it just might be the one we …read more
[Frank Adams] liked the keyboard on his Lenovo ThinkPad T61 so much that he decided to design an adapter so he could use it over USB with the Teensy microcontroller. He got the Trackpoint working, and along the way managed to add support for a number of other laptop boards as well. Before you know it, he had a full-blown open source project on his hands. Those projects can sneak up on you when you least expect it…
The first step of the process is getting your laptop keyboard of choice connected up to the Teensy, but as you might …read more
Hackers love 3D printers. In fact, they might love them a little too much. We
hope know we aren’t be the only ones who couldn’t turn down a good deal on an overseas printer (or two). But when you’re not pumping out plastic boats and other PLA dust collectors, what are you supposed to do with them?
Well if you’re like [Uri Shaked] you could hand them a pen and tell them to get writing. The holidays are coming up quick, and somebody’s gotta sign all these cards. In his detailed write-up, he shows how he was able to add …read more
If you’ve spent an afternoon at the sticks of a remote-controlled aircraft, you’re probably well aware of the great limiter for such exploits: battery life. In the days when most RC aircraft were gas powered it was easy to cart along some extra fuel to keep the good times rolling, but now that everything except big scale models are using electric motors, RC pilots are looking for better ways to charge their batteries in the field.
Though it might seem counter-intuitive, [Adam Pyschny] is of the opinion that the best way to keep his quadcopter batteries charged is to simply …read more
This project of [Nathan]’s certainly has a playful straightforwardness about it. His Skype ‘Kiss’ Interface has a simple job: to try to create a more intuitive way to express affection within the limits of using Skype. It all came about from a long distance relationship for which the chat program was the main means of communicating. Seeking a more intuitive and personal means of expressing some basic affection, [Nathan] created a capacitive touch sensor that, when touched with the lips, sends the key combination for either a kissy face emoji or the red lips emoji, depending on the duration.
Capacitive …read more
Have you ever looked at your cat and thought “You know, my kitten really needs an electric skateboard!” Probably not, but this seems to have happened to [Kim Pimmel] while looking at his cat MIDI, so he decided to build one. This process involved building a simple, low powered skateboard with a Feather mainboard and motor controller combined with a laser-cut switch mechanism. When [Kim] puts a treat into the mechanism, the cat pulls the switch and the skateboard moves forward, moving into a brave new e-skateboarding feline future. MIDI looks somewhat unimpressed by this whole business, but I suspect …read more
To say that the Commodore 64 was an important milestone in the history of personal computing is probably a bit of an understatement. For a decent chunk of the 1980s, it was the home computer, with some estimates putting the total number of them sold as high as 17 million. For hackers of a certain age, there’s a fairly good chance that the C64 holds a special spot in their childhood; perhaps even setting them on a trajectory they followed for the rest of their lives.
At the risk of showing his age, [Clicky Steve] writes in to tell us …read more
