Calculation of busbar impedance with Blender Fasthenry. You can quickly create busbar shapes with curvatures and turns and calculate their resistance and inductance at different frequencies. Also, you can now change the width and height of individual segments. Dimensions are also visualised! #b3d #geometrynodes #electronics #Engineering #Science #pcbdesign #hardware #physics #Simulation #kicad

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

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

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

simulating layouts with Blender FastHenry! you can now export spice netlist of your Blender scene and run a layout spice simulation. Here I am using kiCAD Ngspice to see study the switch node voltage ringing of NMOS half-bridge with TO-220 packages. You can see how moving DC link capacitors closer, and shortening leads reduces the amount of ringing and overshoot. Blender 🔶 KiCad PCB Daniel Bogdanoff Dave Jones

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

continuing with my PEEC solver in Blender for inductors. Now I have a basic Python/Numba code that can calculate skin and proximity. You can see as the frequency increases the current shifts towards to the outer surface and also gets affected by adjacent turns #b3d #geometrynodes #electronics #Technology #science

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

How do we enable single-layer PCBs to support the routing complexity of multi-layer PCBs? We're making a "Bridge-Programmable Interconnect" chip. This chip is "programmed" by traces etched on the top layer of the PCB, it allows any configurable pin to connect to any other configurable pin Why is this a big deal? Single-layer PCB etching can be done in minutes on a UV laser, but because they don't have vias it is impossible to change layers. Using an interconnect chip, you are guaranteed to be able to route any signal over any other signal. By placing these on your single-layer PCB, you can reconfigure wiring such that you don't need any vias!

if you are using someone else's garbage saas ai design review product, stop... all of if it is waste of time and i'll give you something better for free that runs with whatever analysis tools you want. altium-cruncher 2026.6.7 public release kicad-cruncher 2026.6.7 public release altium-cruncher is cli tool built on the altium-monkey library. (kicad-cruncher is built on kicad-monkey) here we show the "design_review" (dr) command dr converts an altium project into a simple graph-spatial-topological format specifical design for llm's - json netlist with links with detail indexes into the schematic SVG elements/groups - enriched pcb SVG heavily decorated with links back to the the json graph - all schematic notes in json form - SVG schematic/pcb elements are heirachically grouped w/ tags for the llm to build its own internal map of subcircuits with linkage to copper artwork subsections. - full part parameter linkage - an .md with a guide for codex/claude on how to step through the eviscerated project. - bonus: schdoc and pcbdoc in a raw json serialized format (what altium uses internally but doesnt give you from teh gui). this format is the literal json form of the altium format essentially all of the resolved schematic graph, physical topology, layer stack information and metadata to do make best use of current frontier and local llm techbology it actually was an accidental discovery. better than a netlist. no vendor lock-in. gives you some help without pretending its 100% . no need to waste tokens on full image processing,etc. this dataset works better, is simpler, and compatible with local llms. can help save some time and give you another set of eyes before a release. works on win/mac/linux gratis!

🚨 Electrical engineers are going to hate this. Someone just turned React into a circuit board factory. Write code. Get a real PCB manufactured and delivered to your door. It's called tscircuit. React for Electronics. No Altium. No $10,000/year licenses. No 6-month learning curve. You write React components. But instead of and , you write , , and . The same way you build a website. That's how you build a circuit board now. Here's what this thing actually does: → Design real circuit boards using TypeScript and React → Edit code in your IDE, watch the circuit update in real time → Auto-generates schematics, PCB layouts, and 3D previews from your code → Automatic part selection and bill of materials generation → Built-in autorouting algorithm for PCB traces → Export to Gerber files and send directly to a manufacturer → Online playground. Design circuits in your browser right now. Here's the wildest part: The creator wrote 40 lines of TypeScript. From that he got a full PCB, a schematic, and a 3D preview. Then he exported it, sent it to a manufacturer, and got a real working circuit board delivered. 40 lines of code. A real physical product. This is free. Write React. Get hardware. $20K+ in bounties already paid to contributors. 8 years in the making. 100% Open Source. MIT License.
