I am working on a small project that uses Tailwind CSS. Normally, I always start programming UI things in HTML and then wonder why it's not as clear and clean as I imagined. Most of my work actually always takes place in the backend. In order to proceed with this project in a more structured way, I wanted to create a few user interface layouts before I start programming.
I think the tool of choice for professionals is Figma. However, I thought to myself, with Inkscape I can certainly implement this for my purposes. When I wanted to assign a color to the first elements, I found it very complicated to take the Hex triplet from Customizing Colors and assign them again each time. I would like to show you how to do this more easily.
A few weeks ago I bought 300 addressable LEDs. To be more precise, 6 x 50 12V WS2811 with a spacing of 25 cm each. Also known as NeoPixel. I wanted to control these LEDs with a Raspberry Pi. So I bought the latest model, Raspberry Pi 5 with 8GB RAM.
After I had set up my Raspberry Pi, I wanted to follow the tutorial NeoPixels on Raspberry Pi by Tony DiCola to carry out a first test with the LEDs. I had already done the wiring as described under Using External Power Source Without Level Shifting. But then I read the following information in the next item Python Installation of NeoPixel Library.
The next line then said that you should watch the tutorial CircuitPython NeoPixel Library Using SPI. With the help of the Adafruit_CircuitPython_NeoPixel_SPI library, an LED ring is controlled via an FT233H. I would like to show how I did this with a Raspberry Pi 5.
My adjustable home climbing wall is now three and a half years old. I made once a smaller and once a bigger upgrade. And next year I would like to do a reset. The main reason for the reset is my need for LED support when memorizing routes. I would like to show how I will plan the reset with the help of Inkscape.
Since a few month I am little bit into meal preparation or meal-prep. Largely through the book The Stealth Health Meal Prep Cookbook by Tom Walsh. However, I transform all the dishes in the book into vegetarian versions with soy granules or seitan. The advantages of Meal Prep for me are as follows.
I have built myself a calculator that helps me to create such dishes independently and to calculate their macronutrients.
Since a few month I try to refactor a few of my web projects. Part of this also involves changes to the design. A topic that I actually like, but have to admit to myself that I'm not good at it. That's why I was very happy about the emergence of Bootstrap and Font Awesome back then. Libraries that you simply use and that's it. For the new design revision, however, I would like to build on Tailwind CSS and Heroicons. But for one of my projects I need a customized icon. I would like to show you how I do it.
A few weeks ago I attended a workshop by Gabriel Prange in the Berlin bouldering gym Berta Block. The workshop was about training for climbing. Part of it has been a strength analysis of the fingers. And this is still one of my weaknesses. I also discovered that finger strength training with a lifting device can have certain advantages over a classic hangboard. Even if I have a very nice beastmaker Motherboard setup.
I already had the 360° Hangboard to warm up at the crag. And enough weight plates. So all I needed was a loading or lifting pin. I found this beautiful Lifting Pin. But I thought I could handcraft a similar one by myself.
I am using my interval timer tool more often in the last couple of month. Mostly for lifting weights with my fingers. And to improve the usage of this tool I would like to play a beep sound before and after every break. One possible solution could be to load and play a audio file in JavaScript. An other solution are OscillatorNodes. I like about this approach that I do not need to buy a audio or create it on my own. And I am even more flexible on sound timing. So I created a small post to play around with OscillatorNodes.
I had a shoulder impingement a few years ago as I started climbing. Solution to the problem has been climbing with an active shoulder and also exercises from the book Climb Injury-Free. In general I can recommend this book to everybody with smaller climbing related injuries. That's why I send every climber friend a few hints and exercises from the book if they have for example a tennis or golfer elbow. Since approximately two month I have a tennis elbow or lateral epicondylosis. So today I have decided to build myself a wrist roller or dowel constrcution.
beastmaker Climbing Motherboard
Last week I have been using three different beastmaker Motherboards. Once at home, once at my lead climbing gym Magic Mountain and once at a local bouldering gym südbloc. My weight might be jumping from day to day a little bit and also between morning and evening, but the gap was noticeable. This was no surpise anymore after I found this Grippy post on Instagram. I am writing in this post a small tutorial based on this post to recalibrate your beastmaker Motherboards loadcell. Just in the case you may do not have Instagram and also to spread the word for this small issue.

As I bought my beastmaker Motherboard setup I was a bit upset. I did expect from the Motherboard and Grippy App somekind of digital tools to test my finger grip strength and improve it by a training plan or workout. The part with the workouts was fine. There existed a few predefined by big names of the climbing community and there was the possibility to add your owns. Unfortunately there didn't exist precise finger strengths tests as you may know them from Lattice Trainging for example. Until I opened the Grippy App yesterday.
