Hand inker

Hand inker

Here’s how to make a handheld “hand inker” from a HP ink cartridge – you can use this to print on walls, people, beer… [via] – Link.

But wait there’s more! Check out this cool kit if you want to make your own (or another version of this hack). 96 dpi Serial Inkjet Printer Kit – Link.

    This would be handy in a sketch book as a time/date stamp. Just wave it accross the paper, and the current time and date (involves some kind of time algoarithim of course) would be printed.

    I really like this idea, but the link doesn’t include enough info to build your own. At the very least, you’d have to start reverse engineering the cartridge from scratch.

    I’d like to see an implementation using a wheel on the bottom (or scanner from a modern optical mouse) to get the printing sized correctly. It looks like this version relies on the user moving it at an appropriate speed and direction. This can be a benefit, though, for neat effects.

    Argh! Brain storm! What if the thing were mounted in the bottom of an optical mouse, so that it would read the X and Y position and put down dots based on a source image? You could then scribble in a picture. Ooh, ooh, what if the source picture were just a repeating pattern? It would be like some kind of magic Zip-A-Tone brush! You’d only really need one jet, too. The whole thing could be built into something the approximate shape of a chisel-tip marker.

    If I didn’t have so damned many things already in progress I’d give it a shot.

    It actually exists as a commercial product:

    But in maker spirit I love the idea of building one.
