Over the past months I have been working on a private project which is about logging piano keystrokes. The idea is to have a Raspberry Pi cable-connected to a digital piano and have it read the piano’s MIDI signal. While […]
The date of this blog post’s publication coincides with Denk Development’s fourth birthday (or rather founding day). Back in early 2016 I started to receive requests from people on the internet, who had seen my YouTube videos in which I […]
When starting a new Arduino project, one typically starts with a blank .ino file. Over the past years I have identified software patterns that appear across almost all of my Arduino projects. To better support those, I have created an […]
The ShiftRegister74HC595 Arduino Library simplifies shift registers usage. It allows you to set single pins of your shift register either high or low, just like normal Arduino pins. It thereby removes the overhead of shifting out bytes that were created […]
Back in January this year I was commuting to work and routinely opened the daily coding problem email: “Good morning! Here’s your coding interview problem for today. […] Assume you have access to a function toss_biased() which returns 0 or 1 with […]
Learning piano pieces can take some time. For some piano players a difficult aspect of it is reading the notes. If one gets used to memorizing them, or (even worse) always writes the corresponding letter above them (e.g. “c” or […]
In this article we define and publish the exact pre-flop probabilities for each possible combination of two hands in Textas Hold’em poker. An online tool at tools.timodenk.com/poker-odds-pre-flop makes the data visually accessible.
In late 2017, small groups of our class were given the task to delve into the assembly language and write a program for the 8051 microcontroller, as part of the Low-Level Programming lecture. This post documents the project MOV is Turing-Complete: 4-bit […]
This post functions as a quick development update on the Math to Image Conversion Bot (on Telegram), the TeX math to image conversion tool (at tools.timodenk.com), and the API that serves them both. The objective is to convert TeX math-code into images.
The ShiftRegister PWM Library enables usage of shift register pins as pulse-width modulated (PWM) pins. Instead of setting them to either high or low, the library lets the user set them to up to 256 PWM-levels. This post serves as […]
