Repairing Dead USB Flash Drives

crystal

Over the last few years, [Tobias] has repaired a number of USB Flash drives. This strikes us as a little odd, given small capacity Flash drives are effectively free in the form of conference handouts and swag, but we’re guessing [Tobias] has had a few too many friends lose their thesis to a broken Flash drive.

In all his repairs, [Tobias] found one thing in common The crystal responsible for communicating with the USB controller is always broken. In a way, this makes a lot of sense; everything else on a Flash drive is silicon encased in an epoxy package, where the crystal is a somewhat fragile piece of quartz. Breaking even a small part of this crystal will drastically change the frequency it resonates at making the USB controller throw a fit.

[Tobias]‘ solution for all his Flash drive repairs is to desolder and change out the crystal, bringing the drive back to life. Some of the USB Flash drives even have multiple pads for different crystal packages, making it easy to kludge together a solution should you need to repair a Flash drive five minutes ago.

This is a peer-to-peer filesharing network

[Aram Bartholl] is building his own filesharing network that screws those fat cats who want to control your freedom. He’s added file cache devices throughout NYC (five so far but more to come) that are anonymous and free to use. Upload what you want, download what you want. They’re completely offline which means monitoring who’s doing what gets a lot harder and quite possibly requires a warrant from a Judge (we’re obviously not legal experts, your mileage may vary).

As for the slew of comments that are sure to point out the dangers of malicious USB device; We think everyone knows they’re taking on some risk when connecting to a USB plug protruding from a brick wall.
