Drawing schematic diagrams

Several people have asked me what I use to produce schematic diagrams for circuits I put on my website and here on the blog. Well I use a package called sPlan which is available from http://www.abacom-online.de/uk/html/splan.html.  This is the package that many SPRAT authors use. Mine is an early version but the latest version is available for 39.9 euros.

Abacom has a range of useful resources such as front panel labeling software and some very simple PCB layout software.  sPlan is remarkably easy to use and a circuit like the Tenbox can be drawn up in about an hour, simpler circuits even less time.

The Abacom website gives details of distributors in many countries.
