Turtles are Here

Welcome to Turtlesarehere.com

(Latest Update: 11 November 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, a Proportional Temperature Controller and a heap of other stuff.

The latest additions to this site are my Oxy-MAPP oxygen cylinder adaptor, some lathe maintenance, and my experiments with sand casting.

I still get quite a few contacts for the 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

My major project remains 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 still in the final stages of commercialization while I  earn the capital to complete the project.  This has been an expensive and somewhat frustrating exercise beset by unavoidable delays and the occasional opportunistic diversion.

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.
