Motorbike Helmet Sound


In this post I show how I built headphones into my motorbike helmet.

Since I started riding a motorbike, I gradually took on challenges associated with it, such as riding on the motorway, filtering, and lately – riding with music (sometimes). While it can be considered less safe, it presents a different set of challenges and offers a different experience. Your visual acuity elevates, as you compensate the lack of sound cues from the environment, watching out for more dangers and preempt other road users’ actions.

Listening to music while riding puts the experience many levels up. The tactility of the road, the smell, the wind, are now part of the music experience. Pick the right track, and the ride becomes even more visceral while you massage your cerebellum with heightened senses.

Electric Bicycle Conversion

Once upon a time I took it upon myself to create an electric bicycle. At the time I was still doing an daily commute to work 16km both ways, and thought it would be a good alternative to a car. The point was also to learn about bicycle mechanics through practice and have some fun with tools.

Fixing Canon 7D “Cannot communicate with battery” issue


A few months ago, my 7D started throwing up this error, which would refuse to read the battery (even though fully charged) and would actually discharge it rapidly if left inside the camera for a few hours. Searching online for the issue revealed that it’s a common problem for many users, and actually a manufacturing defect in every 7D (MKI), though doesn’t reveal itself to everybody. There is a solution, which I found thanks to the author of this video, which details exactly what the issue is and how to fix it in less than 10 minutes.
My documentation basically follows the exact steps in the video, so hopefully this will help someone as well if you want to know what’s up at a glance.
