I suddenly felt the urge to buy a new 3D printer when I saw the Prusa Mini in action. I’ve been using my old Alfawise U30 for a few years now and it’s time to upgrade. So on Christmas Eve I opened the box containing a new Prusa Mini+. It took me about 7 hours to put it together.
I have a rainwater tank in my garden and I’m a tinkerer, so I decided to do some water level monitoring. For this I used a Raspberry Pi Pico W, which is small, cheap and has integrated Wi-Fi.
Who could resist building their own gaming console? I decided to build an Arcade Cabinet, in the “tabletop” version, also known as a Bartop. I watched several American videos (they all do it the same way) and adapted it a bit for Czech conditions and my own needs (no nail gun, no joysticks, no rubber around the edges). Finally, I found a reasonable use for my Raspberry Pi 3A, which was “lying around in a drawer”. All I had to do was install Retropie on it. I had already done that in the past, but the whole point is to have your own “hardware”, or better yet, a box.
I created an Internet of Things smart box for ExitShop to display the current number of orders and, most importantly, play a melody (like Super Mario) when a new order arrives.
In our house, we have underfloor heating controlled by a Tecomat box, which opens and closes valves based on the temperature in each room and the set target temperature, allowing hot water to flow into each room separately.
I built my weather station a few years ago, but only now do I dare to write an article about it. The weather station is open source, but there is no documentation or anything like that. You can find it on GitHub for inspiration. It’s really just a project for fun.
OttoDIY is an open source project with a wide community. Essentially, it is a small robot made up of an Arduino, 4 servo motors, an ultrasonic sensor, and a few other parts from a 3D printer.
I made a digital thermometer using the following components:
Today we will show you how to make a stool and how it can help prevent hemorrhoids or constipation. A stool is a small chair that you can pull out from under the toilet bowl when you visit the bathroom, sit on the bowl, and place your feet on the stool. This will make it more natural for you to do your business.
Today we will show you how to create a shared disk in your local network. We will use Raspberry Pi and Samba software for this purpose.
Raspberry Pi is a tiny computer that can be used for many things. We will show you how to build your own web server on it. It won’t have any graphical interface, we will control it like proper nerds through the command line.
I bought a hamster for an ungodly amount of money at Petshop for my workplace. His name is Pixie IV. and yes, he is already the fourth dwarf hamster with this name… don’t ask what happened to III.
This article is a follow-up to an older piece - How to Make a Pallet Bed with Lights Like a Pro - where I used a regular 20m string of lights to illuminate the bed and somewhat falsely labeled it as LED lights in the article…
My friends often call me a true hipster, DIY lover, handmade enthusiast and other similar names. I simply enjoy doing manual work that deviates from the common understanding of consumer society.
My childhood dream came true and I built my own remote-controlled car. What does it contain?
First, you need to find pallets, which is almost a superhuman task. If you want new, beautiful, standardized EURO pallets with a load capacity of 2 tons with evenly distributed weight, you will usually encounter an approach like min. 300 pallets, 250 CZK / piece, where do you want to send the truck? But if you’re a true hipster like me, you’ll settle for used and completely mismatched pallets. For example, the company LEDtech internet trade s.r.o. specializes in them. 
I’m back after 9 months, just like when a child is born, I am reborn on this blog. However, let’s get to the topic.
