DIYPad: FCC iPad teardown

DIYPad: FCC iPad teardown

The tinkerpaws over at iFixIt managed to scare up the prematurely posted FCC internal photos of the iPad and were able to remove the PDF layer obscuring the manufacturer parts information. Check out their analysis of the FCC photos. Apple requested this information stay concealed until August 17th. Clearly, the FCC ignored them. iPad FCC […]

Socolar-Taylor aperiodic tile models on Thingiverse

Socolar-Taylor aperiodic tile models on Thingiverse

So the bragging rights I mentioned in Monday’s post about the newly-discovered single shape that tiles the plane aperiodically go to mathematician and artist Edmund Harriss, aka Gelada, who produced these beautiful renderings of the Socolar-Taylor tile in Blender and uploaded printable 3D models to Thingiverse. There’s more info and images on Harriss’s blog, Maxwell’s Demon. [Thanks, Edmund!]

MAKE on an iPad (sorta)

MAKE on an iPad (sorta)

In the Apple guide tour videos, you can see that the person using the iPad has MAKE magazine bookmarked! I haven’t seen an iPad in person, but tablets are interesting to think about when it comes to portable computing. I’m really looking forward to hacking an iPad. When the iPhone came out, jailbreaking and doing […]

Solar dress uses nanotech-based conductive thread

Solar dress uses nanotech-based conductive thread

While this dress by Abbey Liebman incorporating flexible photovoltaics for charging personal electronics is interesting, what really caught my eye was the fact that it uses an improved type of conductive thread based on a proprietary blend of polymers and nanoparticles.

You click on a link and buy some silver-based conductive thread right now, but over the course of years, the current silver-based threads will slowly oxidize in air and the conductivity will start to degrade. Presumably, the new material (from the Hinestroza research group at Cornell) does not.

About a year ago I was considering a tutorial for Make: Projects about making one’s own conductive thread using carbon nanotubes (CNTs). At the time, you could buy small samples of CNTs from several places around the web at “educator’s” prices. Research on CNT-based conductive inks has shown that carbon nanotubes dispersed in water bond strongly enough to cellulose in paper to resist washing and prolonged mechanical wear, and would also, presumably, show similar performance on cotton thread. So I’m pretty sure you could make durable conductive thread just by soaking regular cotton thread in a dispersion of CNTs in water. Unfortunately, more research has shown, pretty conclusively, that carbon nanotubes are bad for you. Which is probably why the supply of those accessible “educator” samples seem to have dried up. Oh well.
