What is a Reciprocal Roof Roundhouse?
A reciprocal frame is a class of self-supporting structure made of three or more beams and which requires no centre support to create roofs, bridges or similar structures.
A reciprocal roof is a self-supporting spiral of timbers where each timber rests on the last and needs no central support. It is assembled by first installing […]
I am looking into replacing the stepper motors on my motion control head with PID controlled DC motors. This should allow me to make improvements in terms of noise produced by the steppers, and speed. I have previously done some experimenting with PID loops with the Arduino mega and found that although I could get […]
DIY 8m Diameter Conduit Geodesic Dome
Recently I built an 8m geodesic dome. A lot of people in america build domes out of cheaply available EMT conduit. This conduit is nowhere near as ubiquitous and cheap in the UK so I found a fairly similar standard galvanised pipe and put out for quotes from a number […]
Composting toilets use microorganisms to decompose human waste mixed with wood shavings, lawn clippings and other organic matter into humus. Dry composting toilets collect urine and faeces in a sealed chamber beneath the toilet pedestal, where microorganisms decompose the mixture of human waste and extra organic matter. About three-quarters of the material is converted to […]
A while ago I put together some plans for a motion control system for time-lapse camera movement. I designed it to mainly use off the shelf components, with the exception of a number of laser cut acrylic plates. It worked reasonably well, and has become popular with other Time-lapse makers who have used the plans to […]
My final year project has just wrapped up, here are a few images of the final product along with an abstract giving an outline of the project. Message me or leave a comment if you are interested in seeing the full report.
The design for a bone-cement removal tool, which utilises a chipping mechanism to break […]
I have signed up to do the Mongol Rally this summer, an adventure that involves driving a totally unsuitable vehicle over 10000 miles from London to Mongolia (and back!) in order to help raise money for Médecins Sans Frontières and Cool Earth. Our team has just bought a Rover 827 limousine and preparations are well […]
Recently I have been working on controlling my time lapse motion control rig with a standard xbox 360 controller, I have written this brief post to give pointers to anyone else who may be trying to accomplish anything similar. Here is a quick video of my work in progress, unfortunately the motors are rather loud […]
In May I came across the OpenMoCo project which is a community that is producing an open-source photographic motion control system, concentrating mainly on the software side of the problem. For a while I have been trying out timelapse photography and the idea of creating paning, tilting and sliding shots has been interesting but the […]
A short time-lapse video all shot through one window looking over Holcombe, Exmouth and Dawlish. Had problems with dust on the rear element of my 200-500mm that I cannot seem to remove, may try and get some more hardcore lens cleaning tools.
I’m happy with it for my first try, just a short video to get […]
I have been doing quite a bit of time-lapsing recently and have finally worked out a good work flow; so I thought I would write a post about it to save anyone else time in the future in my situation. This guide will tell you how to shoot a time-lapse using your DSLR and import […]
I just got an intervalometer to make time-lapse videos with my DSLR and this is the first time I have tried it out. The intervalometer is just a cheap model off of eBay made by Yongnuo digital (they call it the MC-36 Timer Remote Cord), it allows you to shoot long-exposures, timed-releases and timed-intervals which is perfect for my […]
If you live in Bath you should definitely check out Warleigh weir. About a 30 minute downhill walk from the university campus (more back) the weir is a popular spot on a hot day. I recommend you go during the work week to avoid the masses; on a hot day it can get very busy. The […]
I have started playing round more and more with my external flashes and wireless triggers. The other day I noticed a moth on the window and thought it might make an interesting subject; using a single strobe with slight diffusion placed outside I up-lit the window and got these shots of the various moths that were attracted.
Currently a huge amount of time and money is being invested in the research, development and implementation of technologies to exploit renewable energy sources; it is estimated that £95-billion was invested in new renewable capacity in 2009 alone.  In the Department of Energy and Climate Change’s 2009 report plans were set out to raise the […]
