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. Back in 2008, when I owned a Canon HF10 camcorder (one of the first to record Full-HD AVCHD video to an SD card), this wasn’t the case. It had a reasonable performance for its price, but sooner than later I was missing important video features like zebra patterns and manual gain. I was wondering whether these features could be unlocked with hacks, and the first step was decrypting the firmware.

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.

The Rayovac PS70 Dual USB Car Charger is a nice little gadget that I’m using in my car to charge my smartphone. It costs $8 at Walmart. Although its output current is specified at 2A (or 2.1A in newer versions), it charges many devices at a low current of only 0.5A because it doesn’t correctly identify itself as a fast charger. This can be easily fixed.
