Skyscraper

Sun, 31 May 2026 14:28:09 +0300

SKY-SCRAPER is a small Flask app plus two processing scripts for turning selected regions of a video into a PDF. It is designed for videos where a small control area changes when the content changes. The app lets you pick:

A start time and stop time.
A crop region to extract from each selected frame.
A control region used to detect when a frame is novel.

When processing runs, the script saves cropped frames to tmp/, then buildpdf.py compiles those images into out.pdf. See the source code.

Ricoh SP150 Hack

Sat, 30 May 2026 01:19:43 +0300

Most printers do not have a mechanism to measure the amount of ink left inside their cartridges. Therefore, instead of measuring ink, they use a print counter on the cartridge chip. When the counter reaches to zero, the cartridge becomes unusable, even if there is ink still left. That’s why filling the cartridge doesn’t work. The only “legal” solution is to throw away the old cartridge and get a new one. While searching for cartridges on the internet for my old Ricoh SP150 model printer, I came across a very useful blog. The blog explains how an old chip of the cartridge can be reset just with an Arduino and some wires.

DEHEAD: Anonymization by head detection

Sat, 30 May 2026 01:13:55 +0300

I was looking for an anonymization tool for a project I was working on. Most existing tools follow a two step approach: they detect the face, then blur or mask it. However, this can get unreliable in edge cases where the subject moves significantly, turns sideways, or is viewed from above. Therefore, I built this small tool called dehead (inspired by deface). It uses YOLO to detect the entire head region, and masks it accordingly.

YAM (Yet Another Metronome)

Sat, 30 May 2026 01:04:15 +0300

Yet Another Metronome (YAM) is a simplistic metronome app I built as an amateur musician looking for a free, ad-free, and powerful alternative. Most apps I tried had a BPM (beats per minute) limit around 200, which felt too restrictive. I wanted something much faster, so I built it myself.

This app was created using Capacitor.js, allowing me to deliver a cross-platform experience without diving into native development. Building the whole project took just a week, but I believe learning native mobile development from scratch would’ve taken at least a month.

About

Fri, 29 May 2026 22:10:18 +0300

Hi, I am degD. I like programming, playing guitar and harmonica, and reading all kinds of books, from fantasy to philosophy. The blog’s name, “EOG”, is a combination of the last letters of “the bloG with nO purposE” in reverse. However, this blog does have a purpose: logging my projects and progress for future readers, including myself.

Perceptron

Wed, 25 Feb 2026 12:17:50 +0300

A perceptron model trained to classify sentences as positive or negative. Three optimization methods are compared: Gradient Descent (GD), Stochastic Gradient Descent (SGD), and Adam. Another goal is to learn how a perceptron, building block of neural networks, work by building it from scratch. Dataset consists of 400 sentences, 20% used for testing and the other 80% for training. Most of the dataset generated by using LLMs. 200 positive and 200 negative sentences. You can see some example sentences below:

Cetris

The Project

This Cetris project (Tetris in C) is an old project of mine, from a time when I was learning how to use make for the first time, and compile a C project that is composed of multiple .h and .c files. I got introduced to many interesting problems while working on this project. And bear in mind, that was a time when LLMs hadn’t been invented yet. I remember looking the net for Tetris versions, and trying to decide which rotation logic should I use, and which pieces should be on the board. From the project README.md:

Hikaie

Fri, 20 Feb 2026 16:52:03 +0300

An unofficial attempt at creating an open-source Storytel client, with no direct real-world use. It is MIT licensed, so you can copy and share it however you want. See source code.

UI: Vanilla HTML/CSS
Routing: Custom SPA router

Background & Lessons Learned

This project started as an experiment to see how far I could go without frameworks or guides, using only minimal LLM help. It began as a Flask app, but I switched to Capacitor.js for mobile, expecting it to be easier. While Capacitor.js is great for porting web apps to native, it lacks native features and its plugins are often basic wrappers. For example, I could play audiobooks but not change speed, or download large files quicly but couldn’t abort them.
