Digital Foundry's tools of the trade is a new series looking at the tools - physical and virtual - that DF members use to carry out their work analysing video games and hardware. In this first episode, Will Judd shares his thoughts on digital callipers, specifically the Hozo NeoCaliper.
There are a handful of tools that should be in any PC gamer's toolkit, from the Phillips-head screwdrivers you'll need to build or modify pretty much every PC out there to the Allen keys that can help you adjust sim racing rigs, monitor arms and other more substantial furniture. However, one useful tool I've not seen mentioned much is a set of callipers - whether that's a traditional analogue set or more newfangled digital alternatives. I've used a set of the latter for several years now, and I'm always amazed at how useful these can be for PC building in general - and PC journalism more specifically.
First, the general stuff: callipers are extremely useful for small form factor Mini ITX builds, where you could start by just cramming every component into your case, but it's often better to measure your components before you begin to make sure you'll have enough clearance. Callipers won't replace a tape measure for extremely long objects - I'm thinking of graphics card length, for example - but smaller objects like CPU tower coolers or radiators can be measured quickly and accurately with digital callipers, allowing you to ensure that your intended setup is actually workable in the often limited space available. It's worth pointing out that as well as measuring the size of objects (outer diameter), you can also measure gaps (inner diameter) - the arms on the top of a set of callipers grip in the opposite direction, allowing you to see exactly how much space you have available.
