On my latest bike build, a Trek Speed Concept, I wanted to use Shimano Dura-Ace brakes, because the levers and brakes are a bit nicer than SRAM, with SRAM AXS shifting, which I prefer for being more completely wireless. I particularly like the integrated button the Shimano shifters have. It seemed like it would be […]

I have been wanting to test some microphones capabilities in the ultrasonic range (>20 kHz), which unfortunately most speakers aren’t rated to do. Well, they can do it usually, it’s just not part of the design because it is outside the audible range. I was also hoping to learn a bit more about speakers. So,

In this project, I made myself a business card. It is a solar-charging RGB LED flashlight as well. In this post I’ll talk about the design and some of the testing done, in case you should like to make one yourself. A couple of years ago, I saw a ‘this business card runs Linux’ post

It’s also

So far, I’ve tried a bunch of different microphones and all have worked. Note that this is after turning

The HP Book Studio G9 is very nearly perfect. I need a computer for data science with which I can also travel far and wide as a digital nomad, and I’ve been searching a while for the best one. Besides programming, movies and writing are the other use cases, and the occasional Civilization game. I

One of my coworkers had setup a nice webcam, and looking at it, I thought, wow, that makes a big difference. In the world of working fully remotely, it seems like something worth having myself. I have been relying on built in webcams for ages, and it works, but it could be much better! I

Mini PCs are amazing! But most people will probably have difficulty getting too excited about them, because they are pretty much just small black boxes. TLDR: Mini PCs are probably the desktop of choice for most people these days. Mini PCs (sometimes referred to as Nuc Boxes) are what happens when you take components designed
