The Electric Imp is a WIFI module with a brain. In some use cases it’s used to help connect your device to the cloud, as one of those ‘internet of things’. On other cases (like this one), it is the thing. Marcus has a cool little project that takes temperature readings and pushes them to the cloud.
Since the Imp is pretty power savvy, Marcus was able to power the project using a solar panel and charger. From there it uses a TMP36 analog temperature module to pull readings from. The temperature is read using the ADC and turned into an actual temperature number. The imp handles the rest by using the ThingSpeak api, which then collects and graphs the data.

You already know that GitHub is pretty awesome for hosting your source files, but how about your 3D object STL files ? Awhile back they added a 3D file viewer to give you live previews of your 3D objects. Now they’ve added the capability to see the differences between revisions.
When you compare 2 versions, one object is in green, one is red. Then there is a slider to let you transition between the old version and the new version. This method of comparing 3D models is much better than doing a side by side comparison, as sometimes the difference is so slight.

As more and more people join the new age of home manufacturing and engineering, we need some inspiration. This site has captured 507 ‘mechanical movements’. That means odd shaped gears, pullys, yankers, shakers, clickers, scissors, and engine designs. A lot of the designs are static, but some have been upgraded and animated.
Sometimes it’s cool just to make things move mechanically for the hell of it. A lot of this has a real ‘steampunk’ vibe if you are into making that. These designs can be re-created and possibly 3D printed, laser cut or CNC’d. Either way you should check them out.

This topic recently came up during a conversation with a friend about making laser cut boxes. If you’ve ever bought a kit that has some laser cut wood or acrylic, or looked at a maker bot or something you’ve seen it. Those cool ways that the ends join together (with and without screws), the snap in tabs etc.
So how do you design something like that for yourself ? Well we’ve got a few resources for you.
MakerCase – An online site that allows you to plug in your own dimensions and tab type and it will generate a file you can laser cut to make the box (or edit in another editor)
BoxMaker – Like MakerCase, a few less options in some areas, and some finer settings in other areas.
Tabbed Box Maker – A plugin for InkScape (This is real cool as InkScape is Open Source and you could easily make modifications from within the application)
I also remembered this cool post on Make about different types of joinery that you can laser cut (or CNC). This goes beyond boxes, we’re talking all types of joints, even flexible ones! Since this post has been around awhile there’s also more gold hiding in the comments like bookmark lists to books.
