Smartphone for under a dollar? Cool. SCNR.

But seriously, this is a really cool combination of ubiquitous smart-phones and 3D printing technology. I wonder what more we will see. Will I be able to print myself a new set of contacts soon?


>>The material cost, not including the printer, is under $1.

That's like equating the value of broken-beyond-repair automobile transmission in a slag pile (~$50 worth of steel) with a brand new transmission installed in your car (~$5000).

...or comparing the value of several grams of beach sand (~$0.01) with an Intel i7-990x cpu ($1499).


Not a reasonable analogy. The 3d printer is a general purpose tool, reusable for many many purposes, therefore should not be considered in the material cost. Much like hammers and saws. The cost of the tools, if you want to be fussy about project cost in an accurate way, should be amortized over every single use of the tool for the duration of your ownership of it.

For example do you go to (e.g.) lifehacks and tell them that the "make shelves for $n" is an inaccurate price, because it doesn't include rent/mortgage to have a wall or the cost of a the screwdriver, drills, and saws?


In the context of lifehacks, the direction of the communication is the website telling an individual "you can do this with your labor, your tools and $n in money."

In these "microscrope-for-a-dollar" posts, the communication context is different. It's misleading a mass audience that these devices can actually be made for the amount. There is no implicit assumption of the individual user of the microscope doing the labor nor using their own tools. The same holds true in my analogies.


This is awesome. For DIYbio, the one downside (that there might be a clever solution for) is that sometimes you're analysing mould spores or maybe pathogens, and it seems that you're then being encouraged to rub the surface of those slides all over an intimate device that likely is very close to your face for a good portion of the day.

But hey, that's nit-picking on my part :)


Some previous discussions of similar techniques (from different groups):

Public domain? No immediately obvious restrictions, published on a government website.


So while PNNL (which is where I happen to work) may own and require a license for this particular design, this technique has definitely been used before, and could be reimplemented to avoid issues if necessary.

Note, not a lawyer or representative, just an intern. What I say may be completely wrong.


Right at the top: Available for licensing in some fields. No idea what that means.


Now if there is a device that can detect my kid's ear infections without a trip to the doctor, that would be something.
