Is there anything a smartphone can't do these days?

I'm making plans to start a new project over the summer, and I hope to finish an arduino project combo with MIT AppInventor to build a personal app to use my phone to turn my front door porch light on and off. I'll use arduino programming to control a small relay connected to the light and the AppInventor bluetooth connectivity programming to connect the 2 platforms to make this happen! Stay tuned for updates; I'll have the AppInventor interface design completed shortly and will post pictures here.

But more exciting, there's a new 3D printing kickstarter campaign, OLO, for a printer that works using your phone! As I type this, they've already surpassed their funding goal (they've raised almost 1.8 million in response to their 80K request). Interesting stuff. OLO uses resin, not filament, and it is light sensitive and "grows", pulled up by the print bed (which lays on top of the liquid resin and expands up only on the Z axis as it hardens in a process called "continuous liquid interface production" - CLIP). The resin is poured into a container you fit over your smartphone face and reads your print job from the OLO app you download to your phone, which controls the LED light that your phone provides throughout the print process (which they claim is faster than conventional filament based printers?)

Curious about this, especially at only $99 buy in for this product, this is what I found:

**Recent resin personal 3D printer start ups have not ended up working (NX1)
**Resin is highly toxic and corrosive; it can dissolve ABS and PVC, so it worries me that you'd be handling it or exposing your valuable smartphone to it?
**The resin is proprietary; meaning if the business dissolves, you may have little to no access. Plus, shipping is very expensive due to the toxic qualities of it mentioned above. And it is not manufactured in US, so that adds to shipping fees. I read somewhere that the shipping alone cost more than the product itself.
**Resin print results give very a refined finish and look injector made, so very smooth and shiny. In fact, you can order print jobs through Sculpteo using this material now; check it out.

I haven't backed it yet, but will continue to follow OLO along with TIKO, to see where the personal 3D printing frontier goes.
