With the right mind and purpose, anyone can perhaps be creative enough to salvage and re-use old electrical parts rather than throw them away and add to the e-waste problem. Something like this guy from Africa, Kodjo Afate Gnikou, who impressively was able to construct a 3D printer using old parts from various busted computer peripherals.
Part of WoeLab, Gnikou’s achievement should be an inspiration and a great example on how old pc stuff which are normally left to stock or eventually thrown away irresponsibly can be revived with the right touches and connectivity.
Gnikou’s 3D printer was mostly made from materials he obtained from a junk yard in Lomé, though he did have to buy a few parts. The entire system cost about $100 which is a bargain considering current models on the market can cost thousands of dollars.
