Disco Flashlight Binary Analog Clock?

As multitools have lots of different functions in one case, so [Shadwan’s] clock design incorporates a multitude of features. He started the design as a binary clock using a Fibonacci spiral for the shape. However, the finished clock has four modes. The original binary clock, an analog clock, a flashlight (all lights on), and a disco mode that strobes multiple lights.

[Shadwan] used Rhino to model the case and then produced it using a laser cutter. The brains are — small wonder — an Arduino. A 3D-printed bracket holds everything together. You can see the result in the video below.

Break Your Frames? Print Some New Ones!

3D Printed Glasses

When [Aaron Porterfield] accidentally broke his glasses frame, he saw it as an opportunity, rather than an unfortunate event. He decided he was going to design and print new ones to fit his prescription lenses!

The trickiest part of taking on a project like this is designing the glasses around the pre-existing lenses, because typically, lenses are cut to fit the frame — not vice versa. This is why we’re particularly impressed with the project. [Aaron] was able to 3D scan the lenses using his camera phone and Autodesk’s 123D Catch software (free) to create the lens model! Once he had the lens outline, he scaled it properly by measuring its maximum dimensions with calipers.

Now this is where it gets a bit tricky – designing the frames. [Aaron] is using Rhino to do the design work, and he’s actually laid out the steps quite nicely for anyone who wants to attempt something like this. He describes in detail matching the curvature of the lenses, designing the frame around it, and of course actually fitting the lenses in place.

There is a small caveat to this entire project — The frames were printed on a nice Stratasys polyjet 3D printer — due to the geometry, it might be a bit tricky (or impossible) to print on a traditional hobby FDM machine. Regardless — making your own glasses is some serious geek cred. Nice work [Aaron]!
