3D light stand

The next project is building a stand with a mirror and lights to display figures, models and whatever looks cool on it. It is not aimed to be a tutorial. For a 3D printing tutorial visit my post about 3D printing.

I had a circular mirror, and my idea was to build a base for it which could hold some LEDs inside to add lights to the project. So I started by making a 3D model of the base with Blender.

Next step, using the service provided by 3D Hubs, I printed the base through my favourite printing company 4Delta.

Once finished, I check the size and it fitted perfectly with my mirror.

For the lights I choose to use common LEDs (drain about 2V and 10mA) and I’ll be powering them in parallel through the USB (5V). In order to limit the current delivered by the USB, I added a 240 Ohm resistor to each LED. This configuration will power each LED at the correct voltage and provide about 12 mA per LED. By the way taking into account that this USB can provide up to 1A, then I can power 100 LEDs, so there is no problem powering up my 8 LEDs.

The next step is putting everything together. Ideally I will use SUGRU to glue the parts, but for now I will only use Blu-Tack which can be easily removed. I will use SUGRU later own to make it permanent if I’m happy with the design.

With this, the project is finished and ready to display figures.

Lego Matrix display.

Usually Mondays are for Lego models, but this one is so great that it deserves its own day.

This is how the pixels work.

It is not a playable version… but it shows the potential.

It would be great implementing it with the Lego Turing Machine.
