I’ve created procedural generators of ICs and connectors using geometry nodes. Due to the large number of different packages of ICs and connectors, it might be better to generate their models as and when needed rather than storing an unlimited number of unique 3D models. Also using the new...

This is awesome!! We’re building something similar (a large 3d electronics library with parameterized models) Would love to collaborate!!

In this free Substack post I share code for several machine learning models and engage in hyperparameter tuning that yields a model that delivers superior returns in the Gold market.

This system breaks down because many new ICs have unique footprints and models, so you will still need a library system nonetheless. Besides that, it looks good

I’m using manufacturer 3D models to verify how they fit the actual footprint. Creating something based on a possibly wrong footprint goes against logic imho.

You can use Blender's geometry nodes to solve physics and electromagnetic equations such as Biot-Savart law. You can calculate the magnetic field of a coil anywhere in 3D space and visualise the magnetic fields. Additionally, you can see in real-time how the magnetic field lines change as the coil gets deformed and twisted! #geometrynodes #b3d #blender3d #electronics #Engineering #Science #physics #kicad #circuits

With Blender's geometry node system, you can create fully procedural multi-core cable models, you can control the number of cable cores, how the cables twists and also you can strip back the insulation to show the copper core. Furthermore, you can add shrouding that conforms to the shape of the core and extra layers of additional insulation. #b3d #blender3d #electronics #engineering #science #cables #manufacturing #physics #3dmodels #3dmodelling #animation

Very excited to share the release of my addon Blender FastHenry! Use Blender's powerful modelling capability combined with geometry nodes to run FastHenry simulations! Blender is becoming a multi-purpose tool not just a tool for 3D graphics and animation, but also for engineering and scientific work too. This video shows how you can calculate the impedance of wire bonds and leads of a Mosfet in a TO-220 package, you can see what effect bending the leads and adding a heatsink have on the impedance! hackaday Dave Jones Sybren A.

Designing MRI coils using ElectroMag Nodes! You can visualise the magnetic field lines generated by the superconducting electromagnets in MRI machines and see how making adjustments to them impacts the strength and shape of the field lines, and especially the straightness of lines in the centre In am using the new gizmos in geometry nodes to quickly add and adjust coils. Next I will be also adding the gradient coils. #b3d #geometrynodes #blender3d #mri #art #science #physics #electronics #engineering #simulation #render

One of Blender's powerful capabilities is how quickly you can create models and concepts of just about anything. Here you can see how I create a simple model of motor rotor with electromagnets, you can use geometry nodes to speed up your modelling workflow even more and also make them procedural with animations, and it's a lot of fun too! #b3d #blender3d #electronics #hardware #science #engineering #technology #3dart #3DModel #motors

Wire bonding and lead impedance calculation in Blender FastHenry! I've improved how the simulation results are visualised, the entire objects now gets overlaid with a colour rather than using bound boxes. Red is for showing the self-inductance of a selected objected, yellow for mutually coupled objects and blue for conductive plane objects. Very impressed how easy it is nowadays to code anything with Python and Blender #b3d #electronics #engineering #science #pcbdesign #hadware #geometrynodes #3dmodeling #educational #simulation #fasthenry #altium #pythonlearning #electromagnetics #kicad

You can now use Blender Fasthenry to do PCB layout studies, calculate impedances of loops and return paths and determine how many vias you need! This demo shows how the impedance of DC decoupling capacitor is impacted by its distance from the IC, and the number of vias under the IC and near the capacitor. This is for a two-layer 1.6mm PCB at 1MHz. Blender FastHenry is now a solid tool for layout simulations and impedance calculations, available on Github. #b3d #geometrynodes #engineering #science #electronics #Simulation #kicad #altium #hardware #technology #3dmodeling #pcbdesign hackaday Maurizio Di Paolo Emilio

New update on combining FastHenry and Blender 🔶 , I've added the ability to calculate the mutual inductance between objects! Also developed a basic UI inside Blender to visualise the results and to highlight the inductively coupled objects. This video shows some examples of what can be donw now. First demo shows how you can model the impedance of die bond wires and the coupling to adjacent wires, you make adjustments to their lengths and curvatures and see the results in near-real-time. Second demo shows calculating inductances and mutual inductance of air-core inductors with arbitrary positions and deformations. Third demo shows simulating PCB coils over a range of frequencies for applications such as wireless power and distance sensing. And you can combine this with Electromag Nodes to visualise the magnetic fields! #b3d #blender3d #geometrynodes #electronics #hardware #science #technology #pcbdesign #kicad #altium #ansys #3dart #programmer #python #engineering #semiconductors #circuits #inductors #components

It has finally happened - my first video guide on how to create electromagnetic openEMS simulations with Blender 🔶 is now available! This video guide will show you to first create geometries and specify ports in #blender3d , export them to openEMS, write a few python scripts, and then using geometry nodes to visualise and animate the results back in Blender. The video is based on the Rotman lens animation I did previously as the workflow for it covers a wide range of topics. I hope you find this video informative. Everything is done using open-source tools including #inkscape, #paraview and Octave! #b3d #electronics #hardware #science #educational #physics #engineering #geometrynodes hackaday #openEMS #electromagnetics #tutorial #mathematics #antenna #rf #kicad #altium

Ending 2024 with a teardown animation of the ZSWatch, an open-source smart watch project. It's been a busy year where I have learnt alot and improved my skills in animation, modelling, showcasing designs and writing my own scripts. Open source projects and tools provide a fantastics oppurtinity to learn about designing electronics and hardware and to understand some of the key decisions that go behind creating such designs. They also provide a great platform to showcase new developments and technologies, there's never been a better time to get involved! #b3d #blender3d #electronics #enginnering #hardware #science #kicad KiCad PCB hackaday #smartwatch #opensource

Infinite Photorealistic Worlds using Procedural Generation paper page: introduce Infinigen, a procedural generator of photorealistic 3D scenes of the natural world. Infinigen is entirely procedural: every asset, from shape to texture, is generated from scratch via randomized mathematical rules, using no external source and allowing infinite variation and composition. Infinigen offers broad coverage of objects and scenes in the natural world including plants, animals, terrains, and natural phenomena such as fire, cloud, rain, and snow. Infinigen can be used to generate unlimited, diverse training data for a wide range of computer vision tasks including object detection, semantic segmentation, optical flow, and 3D reconstruction. We expect Infinigen to be a useful resource for computer vision research and beyond.

Chinese authorities are using nets, spraying insecticide and even deploying drones in the town of foshan to fight the mosquito-borne chikungunya virus, which has infected thousands of people. Authorities had reported more than 7,000 cases of the virus as of Wednesday, mostly in the southern Chinese manufacturing hub of Foshan, some 170 kilometers (105 miles) from Hong Kong. The number of new cases appears to be dropping slowly, according to authorities.

3D-LLM: Injecting the 3D World into Large Language Models paper page: Large language models (LLMs) and Vision-Language Models (VLMs) have been proven to excel at multiple tasks, such as commonsense reasoning. Powerful as these models can be, they are not grounded in the 3D physical world, which involves richer concepts such as spatial relationships, affordances, physics, layout, and so on. In this work, we propose to inject the 3D world into large language models and introduce a whole new family of 3D-LLMs. Specifically, 3D-LLMs can take 3D point clouds and their features as input and perform a diverse set of 3D-related tasks, including captioning, dense captioning, 3D question answering, task decomposition, 3D grounding, 3D-assisted dialog, navigation, and so on. Using three types of prompting mechanisms that we design, we are able to collect over 300k 3D-language data covering these tasks. To efficiently train 3D-LLMs, we first utilize a 3D feature extractor that obtains 3D features from rendered multi- view images. Then, we use 2D VLMs as our backbones to train our 3D-LLMs. By introducing a 3D localization mechanism, 3D-LLMs can better capture 3D spatial information. Experiments on ScanQA show that our model outperforms state-of-the-art baselines by a large margin (e.g., the BLEU-1 score surpasses state-of-the-art score by 9%). Furthermore, experiments on our held-in datasets for 3D captioning, task composition, and 3D-assisted dialogue show that our model outperforms 2D VLMs. Qualitative examples also show that our model could perform more tasks beyond the scope of existing LLMs and VLMs.

Sam on Kimi, distillation, and open source: “I have always assumed that there are going to be great cheap models in the world, and we better be the greatest and the cheapest. You get a better deal today, at least at a particular latency, using OpenAI's models than Kimi. We distill our own models. That’s how we make smaller, cheaper models. That’s a very good thing to do. There will clearly be an important place for open source models in the world and people that will want their own weights. We have so much usage of our models that we do not need to be a gigantically high-margin business to be able to afford model training. I would rather people not distill from us, for sure. But this is not in my top ten list of worries.”
