ABACOM - ELECTRONIC SOFTWARE

Hallo,
Ich möchte Lochmaster von meinem alten PC auf einen neuen migrieren. Bei einer Neuinstallation habe ich alle meine eigenen Platinen und Komponenten verloren. Wie kann ich das auf den neuen PC bekommen?

Grüße Wilfried

Maybe this is an option for future updates?

Another option I miss in Lochmaster is the ability to place objects and text outside the PCB.<br/>
I now solve this by enlarging the PCB and covering the additional space with white areas.

Is it possible to have a text-overline in text labels?

Nice gift for the little ones (with children's music and fairy tales) or for the elderly (a jukebox with music from the past).
You can also play your favorite music yourself.

This circuit can be used to extend signals in time.
A small relay can thus switch lighting or other things that operate on low voltage on or off for a certain period of time.
I think this is useful in model railroading, but other applications are also possible.

I was fascinated by Professor Harry Porter's relay computer: http://web.cecs.pdx.edu/~harry/Relay/

Since the whole computer is too complex and expensive, I started with a simplified version of the computer clock.

This is where I got the schematic.
Looks really nice with the colored transistors (I use nailpolish: it's cheap and there is no need to wash the brush)

Wouldn't it be nice to add the office function F4 (repeat the last operation) in a next update? It takes 5 mouse clicks, for example, to change the color of a connection. When many connections have to be changed of color and/or thickness , it takes a while. Multiple selection works too, but you alwa...

A very simple and small digital binary counter with internal and external clock. All the files are here: https://1drv.ms/u/s!AuX-mO-T-I8rjNE4C2y ... Q?e=w7RqBY

A digital pulse generator for testing digital circuits, especially digital clocks. Very useful combined with a 5VDC power supply. Update: Discarded "D3" from output while it gave interference at testing CMOS IC's, the output could pick up noise while it was low. A resistor (10k) to ground wil also s...

I 'm sorry, it was my mistake.
The board I designed consisted of tracks and pads. I redesigned it with only pads at the ends and tracks with holes between them.
Everything is OK now. Even the smallest split will split the potentials now.

I just noticed that using split has no effect on the potential of a copper-strip.
Making the standard split a bit wider on one side does the trick.

A gadget to put on the table when one receives noisy guests

I found the original schematic here: https://model-railroad-hobbyist.com/node/26088?page=2
It works very well with the small SG90 servomotor, I suppose it works with any 5V servomotor.
The servomotor can move to two adjustable positions with a max. angle of rotation of approx. 90 °

Except SOS I don't know any morse code but it was very educational to build the sine generator.

Small, cheap and easy to build. Everybody should have one ;) (If you have a dozen or so remote controles, like me) The photo transistor is connected the wrong way, according to the original schematic, but it does not work connected the "right" way. Perhaps the Chinese put the notch in the wrong plac...

Bernd, You are absolutely right about the latching outputs. You can avoid this by using two 3141 Hall sensors next to each other, one with the text in front and the other with the other side in front (the front detects one pole, the back the other). If you are in a hurry to get a APX9141, I can send...

A very simple but very useful magnet tester.
A North-pole in front of the APX9141 makes the red LED light up
A South-pole makes the green LED light up.
I bought the APX9141 very cheap on ebay (about 4€ for 10 pieces).

A simple, but useful, signal tracer/injector you can buy from "Velleman".
Of course it's more fun to make it yourself

The best controller I have made (up to now). It's based on the schematic from Ron Hoffman: https://www.gadgetronicx.com/diy-model-train-controller-project/ I implemented the rotary/guitar-switch as used in an other controller to get a more realistic feel. 14-01-2020: Schematic is revised for 12VDC o...
