Analysing the Serato DJ timecode signal

Serato DJ (and previously Scratch Live) is one of the leading DJ software applications out there, and in my personal experience by far the most widely used. I have played almost all of my dj gigs with the Serato software since January 2007. Serato DJ and the old Scratch Live, together with an appropriate sound card, form a so called DVS setup, which is short for Digital Vinyl System. Nowadays these software solutions do much much more […]

Oscilloscope Software Project

A personal programming project made up 70% of the mandatory programming course in the computer science minor at Aalto, and naturally, I chose an oscilloscope as my topic as it combined nicely my early studies of electrical engineering and audio signals. It turned out quite nicely (well, I did spend way over a hundred hours on it), and I learned Qt pretty well doing it. The software was done with Python (which was dictated by the course) […]

Password Helper

Remembering passwords can be a pain in the ass, especially if you want them to be strong passwords, i.e. long, complex and different for every service. A password manager software can help a lot, and they have some pretty awesome features nowadays like automatically changing all your passwords every once in a while. However, even though most password managers sync data across all your devices, they fail big time when you need to login to something […]

Fun with Arduino

I got an Arduino Uno starter kit on loan from school for a physical computing project for the Experimental User Interfaces -course. To refresh my Arduino skills from last year (when I did a semi-big project with it on another course), I created a simple set-up and code for controlling LEDs with a potentiometer and buttons. Also the LEDs aren’t just toggled on or off, but instead the voltages are pulse-width modulated to achieve fading in and out. Here’s […]
