Eco-Amp: The Papercraft Passive Amplifier
July 11th, 2012
Passive smartphone amplifiers have continued to gain popularity over the years, and I have to say that I’m somewhat intrigued by this amp that’s completely made out of paper.
Keep in mind that when it arrives, it comes completely flat, and you’ll have to assemble it as shown in the video below. It’s clear that once you assemble it, you won’t be able to flatten it again.
You can get the eco-amp for for $7.99(USD) directly from Eco Made.
