Praise the sun! You will never have that awkward situation where your caliper battery dies just when you need to take a measurement. Sure, if you have the budget, we recommend these near-indestructable high-end Mitutoyo calipers. But these are very fine calipers as well. The jaws are plastic, so not good for hot metal measurements or when you need perfectly flat jaws. In particular, these caught our eye since they are solar powered and have a...

Caliper rule? Tire tread gauge? Ruler? Thread scale? Writing instrument? The Messograf is all of these in one. It is a multipurpose instrument, constructed of chromium-plated brass for those who demand more than just the joy of writing. Many have tried to copy it - none have succeeded. This is the original. This retractable ballpoint pen has a large ink cartridge. Made in Germany.

The most useful tool we've ever laid our hands on. These calipers are really good quality and an excellent choice if you need something better than a cheap 'disposable' pair of digital calipers but you're not quite ready for a set of high-end Mitsutoyo calipers. These digital calipers work by having a capacitive sensor instead of a rack and pinion, so they never go out of alignment even if, say, you accidentally drop them (a few...

We've been looking for a display like this for a long time - it's only 1.5" diagonal but has a high density 220 ppi, 240x240 pixel display with full-angle viewing. It looks a lot like our 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. We've seen displays of this caliber used in smartwatches and small electronic devices but they've always been MIPI interface. Finally, we found one that is...

Say hello to our 1.14" 240x135 Color TFT Display w/ MicroSD Card Breakout – we think it's T - F - T errific! It's the size of your thumbnail, with glorious 240x135 high res pixel color. This very very small display is only 1.14" diagonal, packed with RGB pixels, for making very small high-density displays. We've been looking for a display like this for a long time - it's so small only 1.14" diagonal but has a...

We've been looking for a display like this for a long time - it's so small only 1.3" diagonal but has a high density 260 ppi, 240x240 pixel display with full-angle viewing. It looks a lot like our 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. We've seen displays of this caliber used in smartwatches and small electronic devices but they've always been MIPI interface. Finally, we found one...

The most useful tool we've ever laid our hands on.  We thought we'd use them just for electronics but then we got our hands on these calipers and had so much fun we started measuring  everything. They're indestructible - which is good because we don't know what we'd do without them - and ultra precise which is super helpful when measuring components or when trying to decide what diameter blueberry you prefer the...
