Model Train Speed Controller

An analog model train speed controller for automatic (analog) train traffic and as a stand-alone speed controller.
The schematic is taken from the book: "Elektronische modelbaanbesturing" by P. De Bra (publisher Elektuur/Elektor).
To use this controller you need the "Triangle wave generator".

Re: 75Hz Triangle generator for model train speed controller

There are two good reasons why I draw my diagrams with LochMaster: 1) I don't have the sPlan program. 2) In this way I keep all relevant drawings together. With sPlan, of course, it would look much better and it would probably be much easier to draw. But as my former boss sometimes said: A good tail...

75Hz Triangle generator for model train speed controller

This module can generate a triangle wave for several speedcontrollers (to be pubished soon).
It is a copy from the 1985 Elector book (in Dutch) "Elektronische modelbaansturing".
My model trains have been laying around on the attic for over 30 years, it's time to get them going again ;)

WIN10 - Decimal and thousand separators must differ!

After a recent update of Windows 10, the message "Decimal and thousand separators must differ!" is displayed each time Lochmaster starts up. After the program has started I can easily open other files. Any idea what the cause is? (Program version is 20/02/2019) PS The message appears six times. Rega...

Re: Easy Synthesizer A-D Envelope Generator

All the modules posted here have been built and tested by me. I will add a few photos to the posts. I am not a musician at all, so I can not make a decent sound example. Building and testing the modules is one of my hobbies. Making noise with this machine is also fun! Currently I am working on build...

Dual Power Supply -12V GND +12V

A very simple, but very usefull dual power supply. Output is -12VDC GND +12VDC and 12VAC GND 12VAC Other voltages are possible when you alter the transformer and the voltage regulators. The transformer voltage should be approximately equel to the voltage regulator output. I use the AC outputs to tes...

Small fan speed controller

The ZD153A smoke exhaust fan makes quite a lot of noise. With this speed control the efficiency decreases a bit, but the noise is reduced considerably.
Caution 230V mains voltage, life-threatening!
Not for beginners!
