    Posted on: Apple, Hardware.Tagline: It turns out fixing the unfixable only takes fifteen minutes and a bit of patience.Last week, I wrote that my AirPods Pro case was dead. The battery wouldn't hold a charge, and Apple's only solution was to charge me €100+ for a replacement case. Instead of throwing it away, I decided to try fixing it myself. It cost me €20 and took about 15 minutes. Here is how to do it. Finding a battery I bought a replacement battery on eBay for €20. You need one…

  2. My AirPods Pro Case is Dead

    Posted on: Apple, Hardware.Tagline: Five years later, the lithium-ion reality sets in.I got my AirPods Pro in February 2021. They’ve been my daily drivers for over five years, which, in the world of tiny lithium-ion batteries, is basically ancient history. Now, the case has finally given up. It doesn't work unless it's plugged into a charger. The moment I pull the cable, it's a brick. It’s the classic symptom of a completely exhausted battery. If you’re in the same boat, there are a few things…

Today I feel a bit like that puddle: a bit mortified, a bit disappointed, and a bit of a disappointment. Does evaporating mean failing?

  5. AirPods Max 2: an infuriating love letter

    Posted on: Apple, Review.Tagline: A brutally honest review of Apple's premium headphonesYou've probably read four hundred seventeen reviews of the AirPods Max 2 already. I'm not here to tell you they're "life-changing" or wax poetic about unboxing experiences. I'm a critical Apple fan with a collection of decent IEMs and headphones, and I have strong opinions about where these fit in the audio landscape. Let's address the elephant in the room first: they cost a ridiculous amount of money for ...

  6. A Gaussian Splat Portrait on the Homepage

    Posted on: Programming.Tagline: Rendering a 3D portrait from a single photo using Gaussian Splatting, Canvas 2D, and zero dependencies.I recently watched a video by Tsoding where he rendered a full 3D scene using just a plain canvas 2D element, without any WebGL or Three.js. The core of the video was a simple formula to calculate the position of each pixel: given (x, y, z) x' = y / z y' = x / z It tickled the part of my brain that loves graphics and it was enough to make me want to try the ...
