<p>I've been interested in 3D printing ever since I heard of the idea.
The <a href="http://www.reprap.org/">Rep-Rap</a> is an interesting project.
They're making a 3D printer which will be capable of printing the parts
it's made of. It needs a fair bit of control, and I'd like to do this
control from inside Linux.</p>
<p>Turns out that there's a perfect system for doing this, called the "Hammer".
It's put out by <a href="http://www.tincantools.com/">Tin Can Tools</a>. They
put an ARM processor, with some ram and flash on a 40 pin carrier. All it
needs is +5V and whatever hardware you want to connect it to. I will,
of course, be connecting it to three quad half H-bridge drivers, to run
the stepping motors.</p>
<p>No, I haven't made any progress on it yet. Too many projects in my
life! But I've got the module and their demo board, the H bridges, and
just need to get my butt in gear.</p>
