The 7 "touch screen for the Raspberry Pi is a practical thing for your own projects. But often there are problems with the screensaver. Sometimes the display is simply switched off when you actually want to touch it. Sometimes it is on when it should be off. Ways to improve and control this yourself can be found in this article.
My media player enters the next level and becomes the TACTbox+. For the version of my daughter, it had to be a little more stylish - just teenies. How it looks and works now is described in this article.
With running lights you create amazing effects in a simple way. That's no problem with a Raspberry Pi and some Python code. Even with Lazarus and Free Pascal is easy and visualization is cool.
The more tinkering with the Raspberry Pi, the more circuits you get. If you want to use your Raspi parallel productive 24/7 - e. g. as Smarthome Server - you get constant problems with customizing and extending existing constructions and errors can be anywhere! How that works better, read here.
Through steady continuous improvement (CIP) of manufacturing processes, many companies get to the point, to achieve only minor optimizations. Searching for major potentials lead many companies to the point to implement a multi-machine operation.
"Everything is in the flow". The statement of the Greek philosopher Heraclitus (about 540-480. Chr.) applies in particular to the work of factory planning. Here, it is long-term use concepts with changeable processes to make. One way to visualize results or review concepts is the material flow simulation.
In the article "layout optimization with the circle method according Schwerdtfeger" I introduced the simple and effective method. The recognized problem of the method was: the preparations are quite time consuming. How to solve this, you will read in this blog.
There are a variety of methods for optimizing the layout in a factory planning process. In many cases the method of Schmigalla is used. However, it is quite complex to implement for the start. Much faster for first solutions are the graphic methods. A method for this is the circle method according SCHWERDTFEGER.
In meetings and workshops employees spend many hours of their time. Even more important that this time is best use and results are achieved.
