PSI Design is the parent company of X-Engineering and Delta-Tek which were set up to manufacture and retail some of the more commercially viable designs we have come up with.

In addition to managing X-Eng & Delta-Tek, PSI is a design consultancy specialising in mecanical, electrical and embedded control solutions.

These pages are dedicated to the projects which were either not commercially viable - or just too eccentric (but still cool!)
