We help electrical and electronics engineers start their careers as professionals in PCB and hardware design, signal integrity and power integrity, putting them among the top 5% of hardware designers in 6 months or less. We train teams of electrical and electronics engineering professionals to design state of the art PCBs and hardware from scratch in the fraction of the time it takes to get a new engineer up to speed in high speed hardware design and layout. Finally, we help people (especially EEs) transition to software and AI roles as full time programmers using Python by learning coding the right and intuitive way that we’ve developed. Now engineers, companies and students can build the technology they’ve dreamt of that college hasn’t fully delivered on. To clarify, we’re not a bootcamp. We are a program and a community (Ha = Hardware, So = Software, Fu = ふ Community [in Japanese]). We believe that proper lesson planning and learn hacking techniques and strategies are the way to achieving our dreams in STEM. HaSofu’s mission is to be the premiere education institution for practical learning and application of hardware and software skills. We also provide strategic guidance for small businesses who need content marketing and messaging strategies to get recognition and sales for their tech brands. HaSofu started as a hardware design company, creating PCBs for other businesses who needed outsourcing of their designs. Now we’re pioneering innovative ways of learning STEM skills for companies, working professionals and college students.

Blender looks amazing right now for PCB visualization
Working on a PCB stack-up and cross-section visualiser using geometry nodes in Blender. 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 objects and components. Its fully procedural and controllable using gizmos. This video shows how quickly a PCB design concept using embedded copper coins can be created. Copper coins provide a low thermal resistance path for surface mount power components such as mosfets. #b3d #blender3d #pcbdesign #altium #electronics #gan #sic #widebandgap #engineering #3dmodelling #technology RAM Innovations Geoff Haynes KuasaSemi Ltd Siemens Electronic Systems Design & Manufacturing
One of the best power electronics teachers I’ve ever had the privilege to learn from. Christophe Basso. If you’re trying to learn power electronics, get his books! They’re the best in the business!
Dear all, I have recently been busy working on a new 3-phase neutral-point-clamped (NPC) 3-level power factor correction circuit. The first circuitry associates a classical dq0 plus sinusoidal pulse-width modulation (SPWM) for producing the control patterns for the power switches. I have added an automated calculation macro for letting you select the power P in watts but also the reactive power Q in VARs, adding a capacitive or inductive component to the resistance emulation. I also did experiment adding an extra low-gain loop for balancing the voltage distributed across the two output capacitors as described in the 30-kW Vienna rectifier application note from Microchip (links in the 1st PDF below). While recently visiting customers with Future Electronics, I have realized that many designers were using space vector modulation (SVM) for powering their converters and the schemes are usually implemented via microprocessors. I have read quite a few papers on SVM but never ventured into its implementation, lacking adequate programming skills. Furthermore, applying SVM to multi-level converter gains in complexity compared to a two-level approach. Fortunately, there are people sharing their knowledge like Ranit Sengupta who posted a video on YouTube describing the simulation of a 3-level NPC inverter with Matlab-Simulink. Starting from his explanation and the paper he kindly referred to me, I developed a complete inverter and a PFC, both controlled with SVM in LTspice. The circuits simulate a 30-kW structure powering a 400- or 800-V rail, again with the ability to add VARs to the resistive component. All these models are available for download in TOFPACK zip file available from my page (https://lnkd.in/eNPt3uW6). I know many of you are experts in SVM - what I am not - and I'll be glad to read comments and suggestions.

Developing Simbeor Electromagnetic Signal Integrity Software for Design of Predictable Interconnects!
Insights from DesignCon 2025! - In my tutorial on crosstalk, I used the signal space concept and the unique visualization capabilities of the Simbeor 3DTF solver based on Trefftz finite elements. For those who couldn't attend, I've got you covered! You can access the slides and explore some insightful Simbeor solutions at this link https://lnkd.in/gjDGZaMv - see #2025_01. Here's a sneak peek: the short video below illustrates crosstalk in a stripline configuration. Watch how the power flow density lets you literally see the near-end crosstalk in action! Is this fascinating or what? Here is the video with sound on YouTube https://lnkd.in/gQTYRcGN #simbeor #electromagnetics #signal_integrity #designcon
Practical loop area and inductance, and plane interplane capacitance effects from the PCB stack-up. A thick inner core of your PCB will not provide great capacitive coupling, so, as Lukas shares, keep the power and ground plane layers on as thin a Dielectric as possible.

The attached images show a micro-section of the PCB we've designed for our open-source smartwatch project. ? We are using a 10-layer ELIC stackup with a total thickness of 0.5mm for the SiP. As the SiP uses an LGA footprint, it was not possible to place decoupling capacitors on the bottom side underneath the SoC or memory package. We had to place the capacitors next to the packages rather than close to the power pads, so we had to ensure that the amount of loop inductance introduced by this placement was kept to a minimum. ? The power planes are therefore located on L2/L4 close to the top layer and are interleaved with three ground planes. Due to the low dielectric thickness, the interplane capacitance is relatively high while the loop area is small, allowing us to stay within the PDN impedance spectrum constraints required by the hardware design guidelines of the SoC we are using. #electronics #hardwaredesign #design
?? KiCAD 9 is here! And with it, a host of new features designed to make your workflow smoother and more efficient. One of the standout updates? Sheet pin/hierarchical label synchronization tool A game-changer from KiCAD developer Ethan Chien, this tool simplifies managing sheet pins and their associated hierarchical labels—no more switching back and forth between sheets and schematics. Even a 2% boost in productivity compounds over time. (And when you're iterating hundreds of times, that adds up.) ?? Check out the new release below.

If you don't get it, you're not worthy. ?? My team posted an infographic on [refer to image] a couple of weeks ago and we got an insane amount of impressions and engagements on that post. Naturally, we have to follow up with a webinar, am I right? Soooooooo who's an [refer to image] expert? If you can look at jitter and not blink, let’s talk!
