Repairing CT based 3D reconstructions for 3D printing
First update in a while. I’ve been very busy and haven’t had a chance to blog much lately. Today, I’ll be showing a quick and […]
Lake sediment core photography with basic photography gear.
Lake sediment cores aren’t as easy to photograph as one might expect. They often have a thin surface layer of water, which reflects any nearby […]
The Bathy-Kayak
Two things you can be sure of when doing research involving lakes: Many lakes are difficult to access, with no boat ramps, no nearby car […]
A 3D printed, DIY, lake sediment trap
A sediment trap for lake research is an interesting thing to design. In some cases a trap can be incredibly simple, essentially being a tube […]
Bootlace ferrules for 3D printers.
Today I spent some time doing some maintenance. I fixed a squeaky idler, and crimped bootlace ferrules to all the wires that go to screw […]
Why you shouldn’t calibrate your 3D printer.
Well……not quite. There’s definitely good reasons to calibrate the various axes of a 3D printer. Perhaps a more accurate title would be: “How, when, and […]
A diatom sampler for people who don’t want to get wet.
One of my colleagues is studying diatoms in lakes in Antarctica. However, normally sampling diatoms involves getting wet, which is not terribly fun in Antarctic […]
3D Printing, Arduinos, and Science. How to save money and create cool stuff.
Traditionally, fabrication of bespoke and custom research equipment has been a challenge. We’ve had to make do with bodging together off the shelf parts into […]
Monitoring marks that can take a hit.
Today, I’m going to talk about some surveying stuff. One of the challenges in surveying (and science too) is establishing long term marks for spatial […]
