Fixing whining noise from a DC adapter Oct 30, 2016

I've stumbled upon a cute and convenient DC adapter the other day, with four USB charging ports (up to 4800 mA total), a power socket, and a tablet stand. All of that for less than € 15. USB charger with power socket and tablet stand.

Replacing HDD with SSD in iMac 2010 Nov 30, 2014

It's been exactly four delightful years when the HDD in my iMac 27" informed me it couldn't take it any longer. "Disk I/O error", it said.

At that moment I already had plans to upgrade it with an SSD (solid-state drive). Those are much snappier and completely silent since there are no moving parts inside.

How to add an external power supply to a USB hub Jan 31, 2014

I've been looking for quite a while for a USB hub that would match the design of my iMac. For those who own an iMac a USB hub is a must-have, since Apple have moved all available ports, including even the headphone one, to its back side. Which is in my opinion a typical example of design gone totally wrong.
