Modernising a Leitz Phase Contrast Microscope

High on the list of world changing, Nobel prize winning inventions that nobody has heard of is the phase contrast microscope. This microscope uses some tricks that exploit changes in refractive index within a sample, allowing you to see details of cells that you generally can’t see without staining. The problem with staining cells is that it kills whatever you apply it to. Phase contrast microscopy made it possible to observe processes in living cells and improved our understanding of cell biology. In general, a phase contrast microscope gives you a much better image if you just want to look at really small biological things.

Group Project: Light Trail display

By Matt, Aidan, Derek, Jess & James. Each year the South Swindon Parish Council hosts a light trail at night though the Old Town Gardens. It’s a fun event where you get to walk though the gardens at night viewing different light installations from disco balls to multi-coloured arches and more. Back in the middle of September we approached the council with the concept of us making something for the light trail.

Swindon Geek Night – 1st Mar 2016

Thanks to James et al at AppsBroker, we had another great evening at Swindon Geek Night no. 4. The evening kicked off with Andy Brice‘s talk on Optimisation using Genetic Algorithms – a very accessible intro to GA, with several real life examples, not least Andy’s table planning software: Perfect Table Plan. I then gave a fast, Read more about Swindon Geek Night – 1st Mar 2016[…]

How to 3D Print with Flexible Filaments

The saying, “You cannot push on a rope” remains as apt as ever when it comes to 3D printing with flexible filaments. Most printers will have some form of success straight out of the box with flexible filaments, but don’t be greedy to begin with, turn the printing speed right down. Within this article I Read more about How to 3D Print with Flexible Filaments[…]

Liquid Tape vs a Pi Camera Lead

A while back I was watching either a YouTube video or reading a blog post about soldering wires onto PCBs, possibly a quadcopter power distribution board. After soldering, the guy got out something called liquid electrical tape and gobbed some over the solder joints to reinforce them. Brilliant I thought! Why have I never head Read more about Liquid Tape vs a Pi Camera Lead[…]

Octoprint and the Raspberry Pi Camera Module

The Hackspace recently took delivery of a Raspberry Pi NoIR Camera Module from Farnell – full details are on their website. It is an add-on camera module for the Raspberry Pi which has no infrared filter, making it perfect for taking infrared photographs or photographing objects in low light (twilight) conditions. The camera plugs directly Read more about Octoprint and the Raspberry Pi Camera Module[…]
