BB023WF BB023WF Smart Electronics 3D Printing Accessory Filament Tracker/Counter
Know how fast your printer is actually printing. Watch filament usage as it happens. See peak, current and rolling average printing speeds. Automatically shows filament used per print job by sensing print job start and end and the time for each print job. A printing speed chart is generated per print job and the chart data can be downloaded from the device, locally. This can measure printing speeds up to 2000mm/s. Printing speed data is also sent out the micro USB connector during the print, if you want the data that way.

This interactive PDF is meant to be used as both a reference and a tutorial on NPN and PNP transistors. It doesn't explain a lot of the math or show all the derivations of the formulas but it does give some explanation of the process as well as a good view of how the design is accomplished. Simulation results are used to verify the examples. After using the methods in this interactive PDF a few times, they will become second nature and you will be able to build upon them with your own style of design. The information and methods in this book can and should be used as a tool and a building block for your future design work.

This is a python macro to be used with FreeCad and KiCad for the generation of PCB coils. Two versions are here, one that can be integrated into FreeCad and the other is a Windows EXE version. The output of this macro is to be cut and pasted into the KiCad PCB file. I modified the script to work with FreeCad and added a GUI but I did not create the spiral calculation code.
