Fake Your ID Photos – the 3D Way

Photographs for identification purposes have strict requirements. Lighting, expression, and framing are all controlled to enable authorities to quickly and effectively use them to identify individuals reliably. But what if you created an entirely fake photograph from scratch? That’s exactly what [Raphael Fabre] set out to do.

With today’s 3D modelling tools, human faces can be created in extreme detail. Using these, [Raphael] set out to create a 3D model of himself, which was then used to render images simulating a passport photograph. Not content to end the project there, [Raphael] put his digital doppelgänger to the test – applying …read more http://pje.fyi/PPvntC

Helix Display Brings Snake Into Three Dimensions

Any time anyone finds a cool way to display in 3D — is there an uncool way? — we’re on board. Instructables user [Gelstronic]’s method involves an array of spinning props to play the game Snake in 3D.

The helix display consists of twelve props, precisely spaced and angled using 3D-printed parts, each with twelve individually addressable LEDs. Four control groups of 36 LEDs are controlled by the P8XBlade2 propeller microcontroller, and the resultant 17280 voxels per rotation are plenty to produce an identifiable image.

In order to power the LEDs, [Gelstronic] used wireless charging coils normally used for cell …read more http://pje.fyi/PKwVFl

Printing Bed Off-Kilter? Blu-Tack To The Rescue!

For all their applications, 3D printers can be finicky machines. From extruder problems, misaligned or missing layers, to finding an overnight print turned into a tangled mess, and that’s all assuming your printer bed is perfectly leveled. [Ricardo de Azambuja’s] new linear delta printer was frustrating him. No matter what he did, it wouldn’t retain the bed leveling calibration, so he had to improvise — Blu-Tack to the rescue.

It turns out [Azambuja]’s problem was so bad that the filament wouldn’t even attempt to adhere to the printing bed. So, he turned to Printrun Proterface and a combination of its …read more http://pje.fyi/P25BWF
