Very excited to share this #openEMS simulation of a 60GHz #mmwave radar PCB! You can see how the e-field component is generated and then propagates in the transmission lines towards the antenna array. The radiated electric field shows one main lobe at 0 deg, and smaller side lobes #b3d #radar #kicad #electronics #educational hackaday #blender3d #antenna #rf Altium KiCad PCB FreeCAD (CAD+CAM+CAE) Jacques Lucke Chris Gammell #Physics #Engineering #Science

very excited to share what I've been working on, I've created an addon which allows you to run FastHenry directly in Blender! you can use the power of Blender to create any curve object and then call FastHenry to simulate the resistance and inductance. This demo video shows how you can calculate the resistance and inductance of a bond wire in a power module. You can experiement with different shapes and curvatures and see how the inductance changes. Furthermore you can control the radius with geomotry nodes! Also, you can combine this with ElectroMag Nodes to then visualise the magnetic fields! This addon will be a free update to ElectroMag Nodes #b3d #blender3d #geometrynodes #inductance #electronics #hardware #science #engineering #pcbdesign #educational #magnet #kicad #freecad #altium Maurizio Di Paolo Emilio hackaday

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.

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

Working on PCB stackup visualizer using geometry nodes, this is can be useful to show all the layers and the type of vias in a PCB design, and also can help in advanced designs that have embedded copper coins and components. Its fully procedural and controllable using gizmos #b3d #geometrynodes #pcbdesign #electronics #engineering #kicad #altium #3DModel #Science #Manufacturing #animation

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

Procedural toroidal inductor using gemeotry nodes! You can control pretty much everything! Add turns, control winding wire radius, turn spread and positions, colors. Evenmore, you controll how the windings terminate to the pins! Add you can add a second winding to create a transformer! and finally you can add a label on top! #b3d #blender3d #geometrynodes #blenderart #3dart #electronics #hardware #engineering #science #physics #Arduino #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

This is probably the most complex workflow I’ve ever built, only with open-source tools. It took my 4 days. It takes four inputs: author, title, and style; and generates a full visual animated story in one click in ComfyUI . I worked on it for four days. There are still some bugs, but here’s the first preview. Here’s a quick breakdown: - The four inputs are sent to LLMs with precise instructions to generate: first, prompts for images and image modifications; second, prompts for animations; third, prompts for generating music. - All voices are generated from the text and timed precisely, as they determine the length of each animation segment. - The first image and video are generated to serve as the title, but also as the guide for all other images created for the video. - Titles and subtitles are also added automatically in Comfy. - I also developed a lot of custom nodes for minor frame calculations, mostly to match audio and video. - The full system is a large loop that, for each line of text, generates an image and then a video from that image. The loop was the hardest part to build in this workflow, so it can process either a 20-second video or a 2-minute video with the same input. - There are multiple combinations of LLMs that try to understand the text in the best way to provide the best prompts for images and video. - The final video is assembled entirely within ComfyUI. - The music is generated based on the LLM output and matches the exact timing of the full animation. - Done! For reference, this workflow uses a lot of models and only works on an RTX 6000 Pro with plenty of RAM. My goal is not to replace humans, as I’ll try to explain later, this workflow is highly controlled and can be adapted or reworked at any point by real artists! My aim was to create a tool that can animate text in one go, allowing the AI some freedom while keeping a strict flow. I don’t know yet how I’ll share this workflow with people, I still need to polish it properly, but maybe through Patreon. Anyway, I hope you enjoy my research, and let’s always keep pushing further! :)

If you could only learn one thing that will be relevant for the next 10-20 years, focus on learning how to deal with data. The future is not about faster hardware, smarter algorithms, or better ideas. The future is about DATA, and those who know how to deal with it will stay relevant much longer than anyone else. I recorded a video to show you how easy it is to get started. In the video, I'm using Kestra. For a long time, I was a fan of AirFlow. Then, I moved to AWS Step Functions. Today, I only use Kestra. Kestra is open-source (repo link below) and kind enough to sponsor my work. The video will show you how easy it is to do the following: 1. Run Kestra locally (literally, one command) 2. Build a simple flow 3. Run Python scripts as part of your flow 4. Connect to HuggingFace models If you have never built a data pipeline, open Kestra's Quick Start Guide and follow their examples. (I think it will take you one weekend to feel comfortable with the application and build the courage you need to get into more serious work.)

For the facial animations in my game, I use a technique that yields results similar to L.A. Noire. To keep it simple: I first generate a facial animation video using AI like LTX 2. Then, I create a video depth map from that animation and project it onto a face mask. Using vertex displacement, the depth map dynamically deforms the face as the character speaks. The result looks good in standalone VR. I actually created this workflow long time ago:

This is a worlds first I believe.. Realtime sculpting and animation directly transformed to video. This is a Realtime ai "render", running on top of sculpting and animation I'm doing as I see the video playing. Done using the beta version of KREA AI's new Realtime video model ❤️

"At the Edge of the Galaxy" – Episode 1 I created this video entirely using AI, specifically the Grok Imagine software. I developed the script with Grok . Then I produced it using all the tools available in Grok Grok Imagine , particularly the Agent mode, which saves a tremendous amount of time. I made this video alone, using just a standard computer. I was blown away by the ability to create dialogue that sounds authentic and worlds filled with such lifelike creatures. The consistency of the characters and locations is excellent, and the realism is breathtaking. I don't see what is stopping anyone today from creating a film entirely conceived using AI with Grok Imagine. If you have any questions, please feel free to ask. I will be happy to answer them. If you would like to support my work, the best way to help is to repost the video. Thank you in advance. As it happens, the video is 4 minutes and 20 seconds long (honestly, I didn't do that on purpose)—that ought to bring me good luck, right? Elon Musk

A quick update on this project Since I shared this, it has evolved into a complete Blender add-on and is now 99% finished. It now includes cel shading, anime outlines, compositing tools, and workflow modifiers for both Eevee and Cycles. I've also updated the product page with the latest preview and test files. You can see the material being applied in the video. Product page has been updated to the new shader. #b3d #anime #npr #indieanime #animation #3danime #makotoshinkai #animeyourname #kiminonawa

Tutorial video on how to test face tracking in Unity with face tracking hardware is here! This is probably the question I get asked the most, so I'm happy I finally got a chance to make a tutorial on this. This example demonstrates doing it with a Quest Pro using Virtual Desktop, but it should work with any headset. I've also done it with an iPhone and Bigscreen beyon 2e + Vive face tracker Next one I make will show how to do it without any hardware :D . . . . . Please keep in mind this video is intended for people who are already familiar with Unity and avatar creation or editing. This video does not go over troubleshooting face tracking, or teaching Unity basics, only how to test how it looks without needing to upload the avatar
