Railway modelling scratchpad

Published 31Aug2016, updated 01Jul2024 This page is in group MODELS. It’s a log: newest at the bottom, except there may be newer entries inside chapters. Like for Mobile Station boxes and firmware revisions My «layout» I have other things to do than attempting at real layouts. But this packed and extended table top is a source of much […]

Timing out design by contract with a stopwatch

Excerpt: Can time be part of a contract? Is it a contract when time is included? «Shall we meet at half past eight at the Pub for a beer?» Let’s steer past that one. Timing requirements are important, they are extensively used in hard real-time systems. In some protocols a client does not need to send any «end of request» signal as the server times out after a period of inactivity to close the connection (like HTTP persistent connections). This blog note tries to discuss when timeouts are fine to use, and when they do turn the components’ interactions into a quiz.

My Märklin 37294 DB Class 191 electric locomotive

New 11Feb2016, updated 24Apr2023 (MODELLBAU-WKIP E91 reference) This blog note is in group Models and is about my experience with this locomotive. This is a very nice locomotive that runs in the curves and over the switches like a dream. I have a small layout with almost only curves, see here. I certainly enjoy electric locos. This one […]

My Fleischmann 396071 DR-Baureihe E 60

New 26.Dec.2015, updated 25Jul2021 This blog note is in group Models and is about a Fleischmann 396071 that seems to have the «AC» 3-rail as a rather dubious add-on. (You might drop the intros and jump to The problems right away.) It’s an electric locomotive series E 60, DRG (BR E60). The model is at Fleischmann here, and the real locomotive is […]

Go(-lang) forums matters

New Oct2015, updated 15May2021. This note is in groups Technology and My Go (golang) notes. I think it’s fair to copy my own comments at Go Forum in this note. I would also do newer golang-nuts and golang-dev matters that I have taken part in. The latter forums I won’t backlog. You will have to go there to read […]

Wall cabinet with 45 deg corners

Some of my woodwork: Previous – Overview – Next – (Next cabinet) Published 10August2014, updated 18Jul2019 (figure 15 and 16 and text) When I started with this cabinet I thought it was going to be a follow-up from the Wall-cabinet with curved corners. Despite the strong similarities it didn’t. Five years after Update 2019: See chapter No more sluggish […]

SBB Ae 3/6 II (H0 brass by Lemaco)

Published 3Aug2014. This page is in group Models. Disclaimer. I take no financial interest in this blog note; neither has Lematec asked me to do this. It’s entirely my enthusiasm of the SBB Ae 3/6 II and the fact that I now have this Lemaco brass locomotive, enabling me to shoot and publish pictures of it. (I […]

SBB Ae 3/6 II (1:45 by model rail ag)

Published 17July2014. Updated 16Jan2017. This page is in group Models The vacation of 2014 led us through Liechtenstein. I had done my homework and mailed model rail ag to learn that they welcomed visitors. When we finally found the small non-postsigned locality in a dead end street by a railway station, I was afraid they had […]
