Faced with rising temps, Las Vegas is embracing a simple climate solution: More trees
Climate change is driving more dangerous summer heat across the U.S. Las Vegas, which reached 120 degrees last summer, is planting thousands of trees to help cool its hottest neighborhoods.
Show HN: Chili3d – A open-source, browser-based 3D CAD application (Score: 153+ in 4 hours)
Link: https://readhacker.news/c/6vUzm
I'm currently developing Chili3D, an open-source, browser-based 3D CAD application. By compiling OpenCascade to WebAssembly and integrating Three.js, Chili3D delivers near-native performance for powerful online modeling, editing, and rendering—all without local installation. Access it here:
https://github.com/xiangechen/chili3d
Features:
Modeling Tools: Create basic shapes (boxes, cylinders, cones, etc.), 2D sketches (lines, arcs, circles, etc.), and perform advanced operations (boolean operations, extrusion, revolution, etc.).
Snapping and Tracking: Precisely snap to geometric features, workplanes, and track axes for accurate alignment.
Editing Tools: Modify (chamfer, fillet, trim, etc.), transform (move, rotate, mirror), and perform advanced edits (feature removal, sub-shape manipulation).
Measurement Tools: Measure angles and lengths, and calculate sums of length, area, and volume.
Document Management: Create, open, and save documents, with full undo/redo history and support for importing/exporting STEP, IGES, BREP formats.
User Interface: Office-style interface with contextual command organization, hierarchical assembly management, dynamic workplanes, and 3D viewport controls.
Multi-Language Support: Built-in i18n support with current languages including Chinese and English.

Launch HN: Vassar Robotics (YC X25) – $219 robot arm that learns new skills (🔥 Score: 159+ in 2 hours)
Link: https://readhacker.news/c/6vVfq
Hi HN — I’m Charles from Vassar Robotics (https://vassarrobotics.com/ - not much there but you can order the robot at https://shop.vassarrobotics.com/products/navrim-robot-that-l...)
We are bringing an upgraded version of the long beloved SO-101 robot arms to a $219 price point with improved mechanical design and added intelligence.
See what it can do here: https://youtube.com/shorts/xNyPKJZI400 (demos are sped up as shown in the video)
I’ve spent a few years building RC planes (https://cyo.ng/hangar/) and micro gas turbines (https://set.mit.edu), and I’ve always wished hardware were cheaper so more people could experiment.
I’m now launching a $219 desktop robot-arm kit that keeps LeRobot SO-101’s kinematics, swaps key parts for sturdier, more precise SLA prints, and adds two integrated 480 p cameras. After plenty of supplier haggling, the whole kit costs less than the twelve servos alone. I’ll release the updated mechanical design under an MIT license by June 30.
On the software side, I'll also release an MIT-licensed MCP server by June 30 that exposes the local robot policy as tools for agentic LLMs (Opus 4, o3, etc.) to use in long-horizon tasks. Here's how it works: You can teach the robot new skills through teleoperation. During inference, you simply talk to the agentic LLM using natural language instructions. The LLM then calls the local robot policy through MCP, automatically decomposing your high-level requests into executable robot commands.
Thanks to the LeRobot community for making such an amazing robot accessible. If you’ve contributed to the LeRobot GitHub repo, email [email protected] for a 20% discount coupon as a small thank-you.
I’d love your feedback! Beyond manufacturing, cleaning up the codebase, and writing docs, I’m considering: a force-controlled gripper, a parallel-jaw gripper, an extra wrist DOF (matching the new Trossen and ARX arms), full force feedback on the leader arm (though that may triple the price), a more affordable version with lower resolution each joint, and a longer-reach variant. Which of these—or something else—would be most useful to you?
You can order it here if you want: https://shop.vassarrobotics.com/products/navrim-robot-that-l....
Looking forward to any and all comments!

Link: https://readhacker.news/s/6vVyQ
Comments: https://readhacker.news/c/6vVyQ
I made this 130 mile capable VTOL drone in only 90 days. It can fly for 3 hours on a single charge. That would make it one of the longest range and endurance 3D printed VTOLs in the world.
This is the thing I'm most proud of building to date!
Before this project, I was a total CAD, 3D printing and aerodynamic modeling beginner. I had only built and flown one VTOL before.
SPECS
Wingspan: 3.9 ft (1200 mm)
Length: 2.5 ft (770 mm)
Weight: 5.6 lb (2.55kg)
Airframe: foaming PLA (Bambu PLA-Aero) and PETG structural parts printed on A1 printer, CFRP booms and spars
Battery: Li-ion silicon anode Amprius SA08 cells, 6s2p pack by Upgrade Energy
Motors: 2807 AOS for lift and cruise (unoptimized)
Lifting ESCs: 4 in 1 Holybro Tekko32 F4 45A
Cruise ESC: Flycolor Raptor 5 45A
Lifting and cruise props: 7042 Gemfan (unoptimized)
Flight controller: Speedybee F405 Wing
GPS: M10
Firmware: Ardupilot 4.6.0

This video edit ended up shorter than I planned. Being my first Youtube video with significant post production effort, I underestimated the work required to make a longer in-depth video with voiceover, edited footage, etc.
