In most of my last projects, I used nice miniature connectors from TE. This is, again, no sponsored post. If you ever evaluated connectors, you may know how overwhelming the range of products is. I like to introduce these connectors to you, in the hope you find them as useful as I do. 😅 I…

Well Made Boards from PCBWay
I received new boards from PCBWay for the Always-On project. They are well made for a really low price. As you can see in the previous image, the layer alignment is very good. Also, I do not have to worry about small fonts on the silk layer. I use 1mm labels and fine 0.2mm lines…
Excellent Cases from Distrelec’s RND Brand
First, this is no sponsored post. I like to put my devices into a nice case. It does not only look more professional, but it also protects the electronics from dust and water. If you ever searched for a nice case, you probably know how overwhelming the offered range of enclosures is. Nicer ones, with…
Always-On Project
I just finished a new project, which is called Always-On. This project is a simple bidirectional bridge between the mains-voltage installation and an Adafruit Feather board as a controller. The idea is to have a device integrated into the electric installation. It works as a smart light switch, monitors power lines or works as a…
Snowflake Decoration Available on the Pimoroni Store
We have some great news about my Snowflake Decoration: Starting today, you can buy an assembled version of the project from Pimoroni that can be shipped worldwide. Pimoroni did an excellent job on this project. No soldering is required at all, meaning this is the user-friendliest version of the project ever released! The project comes…
HAL LCD Demo
I added more modules to the HAL layer. The Hitachi LCD driver is now in a stable state. It uses a MCP23008 chip-based backend to reduce the number of wires required to access the display. Video Parts This demo uses a number of Adafruit boards and components: Adafruit Feather M0 (any type) Adafruit I2C /…
Inline AES 256 / CBC Implementation
Today I like to share some encryption code, which can be used in various situations – and is also useful for embedded systems. It is a unique implementation of the AES 256 / CBC crypto algorithm. The goal of this implementation was neither speed nor size. It was written to inline it into existing code….
Good Quality Boards from PCBWay
Recently I received boards for a sensor array from PCBWay. This boards were made in a very good quality considering the low price level. I really like the green solder mask they use, it creates a nice optical effect shifting the green colour towards yellow somehow. The solder mask produces a very nice contrast between…
PCBite Kit 2.0 from Sensepeek Arrived
Last week the new PCBite Kit 2.0 from Sensepeek arrived. The new kit comes with the great PCBite holder from the previous version, which are very useful to fasten a PCB for soldering, rework or analysis. New to this kit are the handy probes, which also can be magnetically attached to the mirror board. The…
Open Position for Step-Up Converter
For a current project I need a step-up converter to get 5 volts from 2.5V-5.5V input. The output of this converter is used to power sensors which drive motors and small heat elements from this source. The average consumed current is 160mA with a peek at 320mA. In the photo you can see the latest…
