Freelance Technical Author

One "hat" I have worn through much of my working life is as a technical author - writing instruction manuals for DIY electronics. Now I am retired I am available as a freelance author and can help (re-)write instructions into good shape. Use the Contact button above if you are interested.

Sinclair Radionics

Some of the instruction manuals I wrote are in the Sinclair section of this site.

4QD (motor control)

In 1991 I started a business making motor controllers for battery applications. Most of our market was one-off retail sales. We needed good instructions! The business was sold in 2014 to 4QD Ltd

Most of the manuals I wrote (and illustrated) for 4QD are reproduced here, A good one to show the level of skill I can offer is Pro-150 instructions, see below. the most are in two formats:

PDF for printing

You will need Adobe's Acrobat to read them. If this is not already installed on your computer, it is freely available via the www.

Those for printing are designed to end up as an A5 booklet (approx 4" by 6") by printing double sided on A4 and folding on the centre line.
