Turtles are Here

Welcome to Turtlesarehere.com

(Latest Update: 1 July 2016)

My humble web site started with the development of an underwater camera housing for the Pentax 750Z, but has subsequently grown to include a Pentax A20 underwater camera housing, Dive Photos, a page on making Printed Circuit Boards, a Data Logger, my CD Welder, an optically aligned PCB drill and a Proportional Temperature Controller.

The latest changes to this site are a reduction in image quality to reduce your download burden and my experiments with sand casting.  Some of my other stuff remains on the back-burner for now.

I have had quite a few contacts for a complete schematic of my CD Welder.  The basic design is fully described on the CD welder pages (with the exception of the main power supply and the microcontroller board)..Amigo

In recent times my major project is the commercialisation of the Amigo, a navigation aid for recreational SCUBA diving.  See the image on the right.

Some of this work was originally posted here but, as the project has developed from an excuse to go SCUBA diving into a commercial reality, the original material has been revised and reposted at aquacoustics.biz.

The Amigo is in the final stages of commercialization.  This has been an expensive and somewhat frustrating exercise beset by unavoidable delays and opportunistic diversions (such as the development of the Amigo Crew).  Retail sales are now anticipated in 2017.

If you’ve got any questions, suggestions, or critical comments I’d be very pleased to here from you.  I will respond to every enquiry.  Please click left here to email me.
