Getting started with VSCP

This article is a collection of links to documents that have good information for people starting with VSCP. Besides reading the complete protocol specification, they explain some of the basic concepts such as the general protocol concept, addressing, the Decision Matrix, masks/filters and much more in an understandable way.

My beer recipes

Fermenting beer Here are all the recipes for the beers that I have brewed so far. Not all of them turned out so great, mind you. I like to experiment and sometimes make extreme things. Some of these beers are, mmm, more of an acquired taste… My better beers are listed in bold, although ‘better’ is a quite subjective statement. Let’s say that these are the beers that I would happily brew and drink again.

Mespelare VSCP Module

VSCP toolchain

Mespelare VSCP Module I’m experimenting with VSCP. The Very Simple Control Protocol is a simple but clever protocol implementation. Its creator made some of the same design choices I would have made, so it will be well-suited for my application as a home automation protocol. I’m not going to describe it here, you can read all about it on Wikipedia or on the VSCP website. Instead I will describe the set-up I have installed to learn VSCP and develop for it.

How does my website work?

In case you wonder what technologies power this website, here’s the what and how.

About my website and me

Thanks for reading my website. No really, I appreciate it. This website is a minimalistic attempt to give something back to the web. As this is a personal website, don’t expect quality content and fancy layouts. If you however like to read, as I do, other people’s endeavours into all things technical, I hope that my sometimes incoherent ramblings offer some information or entertainment to you.

TS-50 USB interface

TS-50 The original way to interface a TS-50 transceiver to a computer used to be through a serial interface converter. The serial interface has since been replaced with USB ports. Luckily it is even easier to build a homebrew USB interface for the TS-50!

Pillar drill bottle capper

Bottle capper I bottle all of my homebrew. Bottling is one of the more tedious tasks of brewing, and consists of different steps; filling the bottle, capping it, labelling and cleaning. The easier and faster I can make these tasks, the better. I have a pretty good work-flow for filling, labelling and cleaning bottles, but capping needed some improvement.

Homemade malt mill

Homemmade malt mill Crushing malt is an important step in brewing. It is important to crush the malt finely so that all starch is easily accessible for conversion into sugar, but care must be taken not to damage the husks too much since they are essential to the lautering process. An ideal mill for the job is a roller mill, since it crushes flour out of the malt grains while leaving the husks largely intact. As an exercise in metalworking skills I set out to build my own malt mill.

Homemade magnetic stir plate

Magnetic stir plate If you want to grow your own yeast, a magnetic stir plate is a great tool. It keeps the wort (and any suspended yeast) in constant motion, improving the access of the yeast to nutrients, and optimizing gas exchange so that produced CO2 is replaced by fresh oxygen. Commercial magnetic stirrers are quite expensive, even second-hand, luckily they aren’t too difficult to make yourself.

Ballistic Evaluation Motor test 3

BEM after firing

This is a report of the third firing of the Ballistic Evaluation motor constructed by the Vlaamse Raket Organisatie (VRO). During the second firing a number of issues surfaced, which were since resolved and this third test is intended to verify these fixes.

Ballistic Evaluation Motor test 2

Ballistic Evaluation Motor

The previous tests with the Ballistic Evaluation Motor (BEM) failed because the motor failed to ignite. To avoid ignition problems it was decided to increase the throat diameter from 2 or 3mm to 6mm. This allows the use of a beefier igniter. Pol machined a new insert for the throat region, and made a hollow brass tube with flange for the ignition, in which the igniter was glued in such a way that the head of the igniter protrudes from the underside of the tube.

Static Test Controller

Static Test Controller

Deze pagina beschrijft de ontwikkeling van een geïntegreerd meetsysteem voor statische motorttesten. Deze electronica interfacet met de Ballistische Evaluatie Motor, leest hier de meetwaarden uit en geeft deze door aan een computer voor opslag en analyse.

Load cell amplifier

Static test This page describes the construction and operation of a device for testing rocket motors. It allows the recording of the thrust generated by the motor during a static test. The recorded data is then analysed using an Excel spreadsheet.

TS-50 serial interface

TS-50 This article describes a homebuilt interface for connecting the TS-50 transceiver to a computer using the serial port.

Note: this article is depreciated, for a more modern and easier way to interface the TS-50 to a computer, please check the post TS-50 USB interface.

My QSL card

My QSL card The picture on the front of my QSL card was taken while departing for a DXpedition to Holmön island (EU-135), off the coast of Umea, Sweden. While preparing for the expedition, I was told that the only means of transportation to the island at the time I would be in Sweden, was a Hydrocopter. I could picture all sorts of weird vehicles in my head, like helicopters with floatation skids etc, but was quite surprised to see this nice vehicle sitting on the ice.
