Tech Projects

With a notebook full of ideas and a desire to share them, this section of the website is devoted to getting these ideas out there. The project are in development and so will be updated over time as they mature. Where possible all project files have been included or at least links provided to locations where they are currently residing.

I should also acknowledge that these project make a lot of use of other open technologies such as the Arduino microcontroller, Blender, Inkscape, and many other sources too numerous to mention. I feel I am standing on the backs of giants and I want to say thanks for all their work that makes my work possible.

The projects described are;

ROV

A small remote operated undersea vehicle intended to be a cheap device to allow inspections of undersea installations down to a depth of 50m.

A Homebuilt Virtual Reality System

The project is a work in progress. It describes a home built VR system based on the Quanum FPV headset used for FPV piloting of remote controlled aircraft, and making use of the GY87 10 degree of Freedom sensor to provide head tracking. It is envisaged this will be coupled to a computer running a game engine like Blender, Unity or Godot which will allow the user to build and share their own virtual environments.

FrankenVinci - How to Resurrect your Dead Da Vinci 3D Printer with a RAMPS Controller

You, like many others have an XYZPrinting Da Vinci 3D printer which has died and you'd rather not send it to the tip. Here's a project description and associated files that may help you raise your 3D printer from the ashes and allow it to run on any Opensource 3D printer software, and any filament.

Battery Discharge Tester

If you are like me, you have a bunch of rechargable batteries kicking around some of which are good and others which are stuffed. This battery discharge tester is a device for discharging the batteries in a controlled manner to identify which batteries need a bit of TLC.

Timelapse Camera Slide - Version 2

This describes a project to build an Arduino controlled Timelapse Camera Slide. It makes use of 3D printed pieces and electronics that were originally for a 3D Printer of my own design. Now repurposed.

Quadcopter V2

This is the second edition of my Quadcopter described below that somewhat improves the aircraft's resilience in a "hard landing".

Quadcopter V1

Originally inspired by an article in the Tech Life magazine and drawing on elements of the Aeroquad project this quadcopter is designed to be a reasonably robust FPV (First Person View) platform.

A Small DeltaWing with 3D Printed Bits

A simple DIY DeltaWing project making use of Coreflute board and waste polystyrene.

The DeltaWing all nice and fresh looking

A Scale Model of the Solar System for Wellington

This was originally going to be a geocache series around the Wellington (NZ) region but grew somewhat. The intention was to turn it into an educational attraction for the region to celebrate science and scientific achievement. Despite great support from the Hutt City Council, GNS, The Phoenix Astronomical Society, and Resene, I was unable to get the necessary agreements from some of the other stakeholders to proceed with this project (at least with myself at the helm).

Hot Water Cylinder Timer

This is a weekend and holiday aware timer for enabling and disabling hot water cylinders.
