Simplex Studium

Inspired by the von Koch curve, and with a little bit of a twist, this design was developed to be a simple 3D fractal. However, as it is really good looking, I've decided to try turning it into a lamp shade. I think it turned out really nice.

The Sun F(ol)lower had an upgrade: It has a new, dedicated board. It simplifies the cabling a lot, and makes it quicker to (dis)assemble. As is, this board can be used as a prototyping board for reading 4 sensors (analogic input) of 10kOhm (to complete the voltage divider) and control 2 digital outputs. What's next: Now that the main board is up and running, the project can move to the next stage: -Improving the algorithm for light sensitivity in various light conditions; -Add a solar panel; -Redesign the structure to hold the servo motors, solar pannel, sensors and all the components.

At first, changing the filament was always a nightmare with this printer. The so called "cold pull"... Not too quick, not too slow... Well, it jammed more than it worked. So... I've done the following upgrade, making it easy to access the extruding block. It's basically a hinge with a magnetic lock. The contact between the heat sink and the extruder block is still guaranteed and the heat dissipation is practically as it was before the upgrade.
