I recently saw a couple of articles on Hackaday regarding the modification of cheap digital callipers. It turns out that as well as being able to interface these callipers to a microcontroller such as an Arduino, there are some hidden functions that are simple to unlock. I was curious because I happen to own a very similar set of callipers already. Well I could not see a perfectly good tool go unmodified for long.

omegat shared his hot air soldering station:
I saw an inspiring post on here; which made me creative. The whole thing should be cheaper than an Aoyue hot air soldering station (~85€).

Ariel Rocholl has been working with Seed Studio on an affordable handheld spectrum analyzer called the RF-Explorer.
It’s a sort of Swiss Army Knife for monitoring, testing and diagnosing ISM band digital communications. It currently supports the 433Mhz, 868Mhz or 915Mhz bands and other bands in the works. The RF-Explorer is currently in beta with Seeed Studio. [via]

The SparkFun Heaterizer XL-3000 heat gun is a handy tool that everyone should have. It’s great for heat-shrink, melting things, and even very basic rework. The size is great for a lot of different applications and it heats up pretty quickly.

Found some GREAT information on Bolt Depot’s homepage, including this printable poster that displays all the different bolts and nuts and connectors along with their official names. Click on the Fastener Tab at the top of the website and there are even more resources, including a great tutorial explaining how fasteners are identified (including how to accurately describe a bolt’s length, type, etc.)
