Turtlesarehere.com has exceeded 100,000 original site visits,
with many many more page views.  Thank you for your interest.

 

I’ve been work on a whole bunch of new stuff, DC solid state relays, a new electric kiln, radio and LCD monitor repairs, some pump experiments and the like.  I’m hoping to post these here soon.

The latest update is with a new SLA printer.  But you might be interested in repair of a Freeview TV set top box, a discrete temperature compensated constant current source for driving LM355 temperature sensors from a 3.3 V supply, my experiments with Lost PLA Casting using Investment, a Reversible Tap Chuck, a Variable Frequency Drive for my lathe and a story about cheap tools.  Other posts include my Real CNC Mill, making stair rail bends, a MIC-6 aluminium heated bed platform for my MakerGear M2 3D printer, a honing guideswitch mode power supply module, refining my Prototype PCB (Printed Circuit Board) Process which involves a Hobby CNC Mill,  a wet sensor for aquariums, redesign of a constant current driver board for a DPSS laser, repair of a Panasonic DVD recorder, 3D printed non-mercury tilt swtiches, 3D printed gears,  a Seiko watch band 3D print using Ninjaflex, and Northern Lights photography.   I’ve got a number of new projects in the works, and some remain work in progress so please do check back from time to time.

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)..Amigo1

My major project remains the commercialization 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 awaiting final field trials.  This has been an expensive and somewhat frustrating exercise beset by unavoidable delays and the occasional opportunistic diversion.  But be assured that the project is still moving forward.

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