French designers build a 3D-printed metal watch
French watchmaker Unitam and 3D printing company Stainless teamed up to build a unique 3D printed watch, essentially the first of its kind. The team created the watch case using laser sintering to melt stainless steel 316L powder on a Renishaw AM250 printer.
The watch, which uses French-made hands and a Miyota movement, isn’t completely 3D printed. However, because 3D printing is now nearly foolproof and almost as good as injection molding, the teams will begin mass producing and selling these watches in the Unitam in Paris.
The watchmaker and the metals company showed off their watch at the Micronora trade show in France’s watchmaking city, Besançon.
It’s a clever and unique use case for 3D printing and I’d love to see more. Sadly, the current 3D printing systems can’t make small, complex parts for watch movements so we’re stuck with making larger, less complex parts until the technology truly takes off.

Analysis backs claim drones were used to attack Venezuela’s president

Analysis backs claim drones were used to attack Venezuela’s president
Analysis of open source information carried out by the investigative website Bellingcat suggests drones that had been repurposed as flying bombs were indeed used in an attack on the president of Venezuela this weekend.
The Venezuelan government claimed three days ago that an attempt had been made to assassinate President Nicolás Maduro using two drones loaded with explosives. The president had been giving a speech which was being broadcast live on television when the incident occurred.
Initial video from a state-owned television network showed the reaction of Maduro, those around him and a parade of soldiers at the event to what appeared to be two blasts somewhere off camera. But the footage did not include shots of any drones or explosions.
AP also reported that firefighters at scene had shed doubt on the drone attack claim — suggesting there had instead been a gas explosion in a nearby flat.
Since then more footage has emerged, including videos purporting to show a drone exploding and a drone tumbling alongside a building.

Bellingcat has carried out an analysis of publicly available information related to the attack, including syncing timings of the state broadcast of Maduro’s speech, and using frame-by-frame analysis combined with photos and satellite imagery of Caracas to try to pinpoint locations of additional footage that has emerged to determine whether the drone attack claim stands up.
The Venezuelan government has claimed the drones used were DJI Matrice 600s, each carrying approximately 1kg of C4 plastic explosive and, when detonated, capable of causing damage at a radius of around 50 meters.

DJI Matrice 600 drones are a commercial model, normally used for industrial work — with a U.S. price tag of around $5,000 apiece, suggesting the attack could have cost little over $10k to carry out — with 1kg of plastic explosive available commercially (for demolition purposes) at a cost of around $30.
Bellingcat says its analysis supports the government’s claim that the drone model used was a DJI Matrice 600, noting that the drones involved in the event each had six rotors. It also points to a photo of drone wreckage which appears to show the distinctive silver rotor tip of the model, although it also notes the drones appear to have had their legs removed.
Venezuela’s interior minister, Nestor Reverol, also claimed the government thwarted the attack using “special techniques and [radio] signal inhibitors”, which “disoriented” the drone that detonated closest to the presidential stand — a capability Bellingcat notes the Venezuelan security services are reported to have.
The second drone was said by Reverol to have “lost control” and crashed into a nearby building.
Bellingcat says it is possible to geolocate the video of the falling drone to the same location as the fire in the apartment that firefighters had claimed was caused by a gas canister explosion. It adds that images taken of this location during the fire show a hole in the wall of the apartment in the vicinity of where the drone would have crashed.
“It is a very likely possibility that the downed drone subsequently detonated, creating the hole in the wall of this apartment, igniting a fire, and causing the sound of the second explosion which can be heard in Video 2 [of the state TV broadcast of Maduro’s speech],” it further suggests.
Here’s its conclusion:
From the open sources of information available, it appears that an attack took place using two DBIEDs while Maduro was giving a speech. Both the drones appear visually similar to DJI Matrice 600s, with at least one displaying features that are consistent with this model. These drones appear to have been loaded with explosive and flown towards the parade.
The first drone detonated somewhere above or near the parade, the most likely cause of the casualties announced by the Venezuelan government and pictured on social media. The second drone crashed and exploded approximately 14 seconds later and 400 meters away from the stage, and is the most likely cause of the fire which the Venezuelan firefighters described.
It also considers the claim of attribution by a group on social media, calling itself “Soldados de Franelas” (aka ‘T-Shirt Soldiers’ — a reference to a technique used by protestors wrapping a t-shirt around their head to cover their face and protect their identity), suggesting it’s not clear from the group’s Twitter messages that they are “unequivocally claiming responsibility for the event”, owing to use of passive language, and to a claim that the drones were shot down by government snipers — which it says “does not appear to be supported by the open source information available”.

Airobotics makes autonomous drones in a box

Airobotics makes autonomous drones in a box
Not far from Tel Aviv a drone flies low over a gritty landscape of warehouses and broken pavement. It slowly approaches its home — a refrigerator-sized box inside a mesh fence, and hovers, preparing to dock. It descends like some giant bug, whining all the way, and disappears into its base where it will be cleaned, recharged and sent back out into the air. This drone is doing the nearly impossible: it’s flying and landing autonomously and can fly again and again without human intervention — and it’s doing it all inside a self-contained unit that is one of the coolest things I’ve seen in a long time.
The company that makes the drone, Airobotics, invited us into their headquarters to see their products in action. In this video we talk with the company about how the drones work, how their clients use the drones for mapping and surveillance in hard-to-reach parts of the world and the future of drone autonomy. It’s a fascinating look into technology that will soon be appearing in jungles, deserts and war zones near you.
