Plant Best Friend - ESP8266 Monitoring - Part 1

I'm obsessed with the tiny microcomputer named ESP-01. It is based on ESP8266 SoC (System on Chip). For my second project, I decided to make a small and simple weather monitoring station for my plant's vital parameters. Temperature, humidity, and soil moisture. Here's the complete tutorial on how to make

Steam Deck a Dream Machine - Expectations from Indie Game Developer

Once in a while, I got super excited about some hardware or software. It's not happening often as it's hard to impress me. Over the time it was Fujifilm X100 (best camera to date), RTX cards (and the software it powers like Quake2RTX, Broadcaster, Canvas), affordable 3D printers, electric

My Developer PC Software List

I needed to reinstall my Windows PC recently. And a first thing to do after is to get all the needed software on it. Over the years I get used to some applications that I can not live without. I also try to keep the list to absolute minimum. Less

AI Driven Concept Art - NVIDIA Canvas

NVIDIA unveiled today awesome new tool named Canvas. All you need to have is RTX graphics card. The application is free. It uses GauGAN neural network to combine final image based on user input. There is a set of tools (materials) to use. And styles for environment setting. Tools for

Using MS-DOS and WordStar in 2021

It was a while since I last used Microsoft DOS. I have a warm memories from that era. I decided to time travel to those years and try to use DOS once again.

FreeDos with QBASIC From a Single Floppy

I remember that FreeDOS had a floppy boot disk. What if I could hack it for an embedded DOS OS and even fit QuickBASIC in? Finally run it on the EeePC in a true Cyberpunk style? It turns out it is possible and cooler than I thought!Customizing DOS is

FLOPPINUX In The Wild

I'm very happy about the overall reception of my latest project. I received many questions and read a lot of cool old-time stories. I did not expect such wonderful reaction :)It was my first project/article that was shared on Hacker News and got to the front page! Hack-a-day write

When I started this project I don't think that anyone will ever use it. To my surprise many people are interested with it. I'm happy about this and obligated to continue refining it.For this small update I did a slightly refactor of the code. I removed Nomad Diskmag content

How To Build 32-bit FLOPPINUX on a 64-bit Operating System

Thanks to the help of pappp I now have the updated instruction for 64-bit operating systems. It is little bit more complicated and I still recommend using VM or some old hardware. Follow my 32-bit tutorial and just make changes listed below. For ease let's make variable with the root

Creating Sample Application on FLOPPINUX

I created FLOPPINUX distribution for running one application in a KIOSK mode. The user should be unable to close the main application nor run any other software. I will show how I managed to do this using just shell scripts.My AppI'm working on an old-school diskmag software. In the

The story of my new FPV hobby

IntroductionI always wanted to have a drone. But living in a big city makes it useless. I would not be able to fly in most places and they are relatively boring. Drones were also very expensive and fragile. Then the opportunity cames as I spend six weeks at Tenerife at

Godot Visual Shader: Cloudy Sky (GLES2)

IntroductionOne evening I was tinkering with my shaders. I was trying to make a tornado like effect. Then I changed the blending effect to add. Unfortunately I was having the camera pointed to the sky and sun. What I saw was an opportunity for a nice "clouds". This is optimized

Raspberry Pi 4 as Perfect Indie Console

Since the first Raspberry Pi I dreamed of making indie arcade console from it. But also as a Godot enthusiast I wanted to use it. Running 2D games was kinda working but it was more like a hack (frt). Here comes the latest Pi. Forth iteration hardware was bumped to

RTX on

There was a time when 3D accelerators were new on the market. When Quake 2 with Voodoo shows what computers can do in real time. Those was very exciting times. Now 22 years later here we are with Quake 2 showing latest RTX capabilities. Welcome to the 2019! Quake II

Godot Visual Shader: Simple Fire

Fire is very complicated and can be made by many techniques. I usually use particles but there is even simpler way using visual shader. For some small detail in the background it's perfect. Also it's super fast. It's the same idea I took with flag shader but enhanced a little

Noise Based Single Terrain Shader

I learn a lot doing my shader experiments in Islands of Shaders, then Mystic Treasure Hunt and now in Valley of Shaders. Over this course I made lot of awesome game worlds. But I lost the track and they became slow and bloated. That's why this last project emerged. It
