The end result - motorized window in a silver stainless steel frame, with the linear actuators and gas struts, shown from the outside half-open.

Swing Gate Motors Come To Help For Opening A Giant Servery Window

[Martin Roberts] wrote to us, telling us about a build that his company, [Ocean View Workshop], was tasked with. Creating a four meter wide window able to open vertically is no small feat, and it had to be custom-built because the local company building such windows wasn’t comfortable working with anything other than aluminum — insufficient for the window’s scale. With massive weight of the glass alone, structural requirements for supporting it, and the mechanical loads to be applied, some careful planning was in order.

To start with, this window had to be motorized, as an average person wouldn’t be capable of pulling it upwards. Not satisfied with the linear actuator choice available, they went to a hardware store and found some swing gate actuators that, in workshop tests, proved themselves to be more than capable of handling way over the weight required. In fact, they were capable of lifting [Martin] himself off the ground without much hassle.

A 1981 Centaur pinball table rebuilt into a coffee table.

Clear Off The Coffee Table, It’s Pinball Time

Like many of us, [BuildXYZ] has always wanted to own a pinball machine, but doesn’t have the space to justify buying such a big and heavy toy. But where there’s a will, there’s a way. [BuildXYZ] figured that if they could build a pinball machine into a coffee table form factor, they’d be at least halfway to justification.

[BuildXYZ] didn’t choose just any pin. After doing a bunch of research, they settled on 1981’s Bally Centaur because it’s an early solid-state machine, and it’s one of the best. It has no secondary playfield levels to deal with, making it much easier to do this project.

Where do we even start to describe this beautiful labor of love? There are too many details to list, but know that it seems to be equal amounts of restoration work and custom work that brought this table together. The build video after the break is definitely worth your time, and you’ll gain a much better appreciation of the amount of time that went into this, from the custom score decoder chip built on an FPGA to the 3D printed replacement drop targets and new acrylic bits to replace the yellowing ones from the playfield.
