Buying a cloned device for a small fraction of the original’s price is often not a good idea, unless you’re handy and like to tinker. One example are cheap Vitamix blender clones, made out of the cheapest parts the manufacturers can find.

This saves you from buying a complete blade assembly unit and upgrades the drive train to better durability and smoother operation.

Today, if you are an amateur who wants to record high quality videos on a budget, you can get a nice DSLR for less than 1000€ which comes with every feature you’ll ever need. If not, you can easily extend the functionality with software add-ons like Magic Lantern.

Over the last year, I’ve been extensively researching an effect called clock drift in the multimedia domain. Clock drift is the deviation of a clock’s speed from the world time standard, resulting in shifts in sampling rates, and this shift leads to parallel recordings from different devices not being […]

Some early Seat Leon 1P Facelift cars with Media-In functionality (AUX, USB & iPod support) suffer from a problem where the mid-tones on the left channel are missing when listening to analog audio through the AUX input, which includes listening from an iPod with the iPod adapter cable. This can be resolved in a couple of minutes by replacing the old AUX port with a new and fixed revision.
