On paper, the ByoWave Proteus controller sounds like a perfect setup for a failed Kickstarter.

Here's some stuff I did last year.

I used to post on this blog whenever I finished a project, but these days I typically just put it on GitHub and call it a day.

Microsoft's Surface line of hardware has some nice computers and accessories.

I always thought that when you connect two mice to a computer, there should be two mouse cursors, one for each mouse.

One of the problems when making a custom fightstick (arcade controller for fighting games) is modern console compatibility.

Having previously made some 3D printed fightsticks (arcade controllers for fighting games) that were just plastic boxes with holes for arcade buttons or mechanical keyboard switches, I started thinking, could I make one that's even thinner?

Fighting games like Virtua Fighter, Tekken or Street Fighter originated at the arcades and have traditionally been played on cabinets with heavy duty joysticks and buttons.

I made a Bluetooth trackball in which all the electronics are inside the ball.

I made an ergonomic split keyboard using the Dactyl Manuform design, specifically the 5x6 version.

You know those days when lifting a finger to scroll a website seems like to much of an effort?

I've been playing around with orientation sensors and Bluetooth HID recently.

I have recently discovered that the HID mouse protocol supports absolute cursor positioning in addition to the more common relative mode.

Perhaps you're familiar with a type of device commonly referred to as a USB rubber ducky.

Remember Logitech's April Fools' video from 2017?

Don't you hate it when you get up from your desk at work to go to the bathroom, only to find out that all the stalls are occupied?

I have recently started making traditional prints of my analog photos and it is a lot of fun in itself, but naturally I am also treating it as an excuse to play with some electronics.

Two kinds of timers are used in a darkroom when making prints.

Update (2021-01-27): I have made an improved version of this project, see here for details.

There are many apps and websites for tracking time spent on projects and I'm sure they work well.

Update (2018-04-21): IKEA has rolled out official support for Google Assistant, so if you just want your lights to work with Google Home, you don't need any of this.

Among other interesting things, Android 4.3 introduced a proper way of accessing notifications from an app.

My previous attempt at a Morse code keyboard worked over USB and used a copper coin as a capacitive sensor.

I never had a Nintendo Wii, but I got a nunchuck controller to play with.

Some time ago I made an emergency mute button that connected over USB.
