Hackaday Links: May 18, 2014

Think the original Pong is cool? How about point to point Pong? [v8ltd] did it in three months, soldering all the leads directly to the chip pins. No sockets required. It’s insane, awesome, a masterpiece of craftsmanship, and surprising it works.

[Jeremy Cook] is building a servo-powered light graffiti thing and needed a laser diode. How do you control a laser pointer with a microcontroller? Here’s how. They’re finicky little buggers, but if you get the three-pack from Amazon like [Jeremy] did, you get three chances to get it right.

NFC tags in everything! [Becky] at Adafruit is putting them in everything. Inside 3D printed rings, glued onto rings, and something really clever: glued to your thumbnail with nail polish. Now you can unlock your phone with your thumb instead of your index finger.

Photographs capture still frames, but wouldn’t it be great if a camera could capture moving images? No, we’re not talking about video because this is the Internet where every possible emotion, reaction, and situation can be expressed with an animated GIF. Meet OTTO, the camera that captures animated GIFs! It’s powered by the Raspberry Pi compute module, so that’s interesting.

[Nate] was getting tired of end mills rolling around his bench. That’s a bad thing. He came up with a solution, though: Mill a piece of plywood into a tray to hold end mills.

The Da Vinci printer, a printer that only costs $500 because they’re banking on the Gillette model, has been cracked wide open by resetting the DRM, getting rid of the proprietary host software, and unbricking the device. Now there’s a concerted effort to develop custom firmware for the Da Vinci printer. It’s extraordinarily bare bones right now, but the pins on the microcontroller are mapped, and RepRap firmwares are extremely modular.

    v8ltd has a great career ahead of him in the 1970 electronics industry.

    Convert laser pointer to laser module. Hmm, why? Laser module is 2$, laser pointer is at least $5.

    FWIW, up to 24-bit animated GIFs aren’t difficult to make. I’d link to my examples, but they are no longer available online.

    Thanks for the mention, Brian!

    It’s so ridiculous and annoying that the PNG group, who should be supporting PNG, refuses to make animated PNG official, and thus making only firefox support them natively. What’s wrong with these people? (And why doesn’t some militant group take over like is the custom in 2014). I guess they are just pissed that MNG was not deemed nice enough and now they are forever virtually pouting, damn spoiled brats.

    Anyway this whole animated gif thing would have been so much easier and better if animated PNG was finally made official since you’d have 24bit(and more) support.

    And talking of PNG, why are there no cameras that save in PNG format? It’s a license free format isn’t it? Another sign of the madness of the world, and of software engineers.
    If I was gates I’d use my evil power to force them to.
