Broken gear on your paper shredder? Don’t throw it out! Print a new one!

by on Mar.29, 2015, under 3d printing, Electronics, Reprap Prusa

I had this industrial paper shredder forever, it always had one broken tooth on the main drive gear that made a cringe-able thump every rotation. (Hence why I acquired it for free :) )

Info of the shredder: The worn sticker says”world ssc5″  after some research I found it to also be known as the “CCS 5000 Achiever”

After many years of use and abuse I finally gave up when the thump became louder and it was very apparent that the gears were slipping now.

Another tooth was broken! Is this the end of my shredder?

More decapsulated chips

by on Apr.21, 2014, under Electronics

Improved my method for decapsulating chips better.
I used a Mr coffee, coffee pot heat plate. With expendable metal plate on top. Used my drill press as a mill with a tungsten carbide drill bit making a small pocket in the chip for the acid to sit in.
I heated up the chips first on the plate then applied a drop of nitric acid. Rinsed with water, heated again then a drop of sulfuric acid water rinse. Then repeated till the dies were exposed.
