75Hz Triangle generator for model train speed controller

[Hougaarden]

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

I really love your analogue projects. Nevertheless, sometimes I wonder why you prefer using LochMaster instead of sPlan for your circuit diagrams? Have fun!

[Hougaarden]

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 tailor can cut straight with crooked scissors.
And there is more: I love using LochMaster and stripboard technology so much that I don't even make PCB anymore, although I have had Sprint Layout for years.

PS There are more circuits in development, you can't do much with just a triangle generator
