Remote Color Controlled Jack-o-Lantern

As usual, this Halloween I decided to create a project related to the season. Using Prusa I3 and Thingiverse, I printed a Halloween decoration where the color is controlled remotely through the Blynk project.
The Blynk project lets you create a mobile or tablet app that interacts with controllers like the Arduino Uno or the Wemos D1 Mini.

BQ Ciclop Home Made

One technology that came up with 3D printers was 3D scanning. There are several equipment that allow you to do this, some more accessible, some less. Some time ago, BQ launched a model called Ciclops. It’s a relatively affordable 3D scanner just like others on the market. However it has a unique particularity. BQ, in addition to launching the scanner for sale as a kit, … Continue reading BQ Ciclop Home Made
