Analog Devices and Antmicro have released AutoML for Embedded, a tool that simplifies AI deployment on edge devices. Part of Antmicro’s hardware-agnostic, open-source Kenning framework, it automates model selection and optimization for resource-constrained systems. The tool helps users deploy models more easily without deep expertise in AI or embedded development.

AutoML for Embedded is a Visual Studio Code plugin designed to integrate seamlessly into existing development workflows. It works with CodeFusion Studio and supports direct deployment to ADI’s MAX78002 AI accelerator MCU and MAX32690 ultra-low power MCU. The tool also enables rapid prototyping and testing through Renode-based simulation and Zephyr RTOS workflows. Its support for general-purpose, open-source tools allows flexible model optimization without locking developers into a specific platform.

With step-by-step tutorials, reproducible pipelines, and example datasets, users can move from raw data to edge AI deployment quickly without needing data science expertise. AutoML for Embedded is available now on the Visual Studio Code Marketplace and GitHub. Additional resources are available on the ADI developer portal.

SK keyfoundry, in collaboration with Siemens EDA Korea, has introduced a 130-nm automotive process design kit (PDK) compatible with Calibre PERC software. The process node supports both schematic and layout verification, including interconnect reliability checks. With this PDK, fabless companies in Korea and abroad can optimize automotive power semiconductor designs while performing detailed reliability verification.

According to Siemens, while the 130-nm process has been a reliable choice for analog and power semiconductor designs, growing design complexity has made it harder to meet performance targets. The new PDK from SK keyfoundry enables designers to use Siemens’ Calibre PERC with the foundry’s process technology, supporting layout-level verification that accounts for manufacturing constraints.

SK keyfoundry aims to deepen collaboration with Siemens through optimized design solutions, enhanced manufacturing reliability, and a stronger foundry market position.

Nexperia’s 1200-V, 20-A SiC Schottky diodes contribute to high-efficiency power conversion in AI server infrastructure and solar inverters. The PSC20120J comes in a D2PAK Real-2-Pin (TO-263-2) surface-mount package, while the PSC20120L uses a TO-247 Real-2-Pin (TO-247-2) through-hole package. Both thermally stable plastic packages ensure reliable operation up to +175°C.

These Schottky diodes offer temperature-independent capacitive switching and virtually zero reverse recovery, resulting in a low figure of merit (QC×VF). Their switching performance remains consistent across varying current levels and switching speeds.

Built on a merged PiN Schottky (MPS) structure, the diodes also provide strong surge current handling, as shown by their high peak forward current (IFSM). This robustness reduces the need for external protection circuitry, helping engineers simplify designs, improve efficiency, and shrink system size in high-voltage, harsh-environment applications.

If you are tired of scale buildup, scratchy laundry, or cloudy glassware, it’s probably time to take hard water into your own hands, literally. This blog delves into inventive, affordable, and unexpectedly easy design concepts for building your own electronic water softener.

Whether you are an engineer armed with blueprints or a hands-on do-it-yourself enthusiast ready to roll up your sleeves, the pointers shared here will help you transform a persistent plumbing issue into a smooth-flowing success.

So, what’s an electronic water softener (descaler)? It’s a simple oscillator circuit tailored to create a magnetic field around a water pipe to reduce the chances of smaller deposits sticking to the inside of the pipes.

Not new, the concept of water conditioning dates back to the 1930s. Hard water has a high concentration of minerals, the most abundant of which is calcium particles. The makeup of deposits leads to the term hard water and reduces the effectiveness of soaps and detergents. Over time, these tiny deposits can stick to the inside of pipes, clog filters, faucets and shower heads, and leave residue on kettles.

The idea behind the electronic/electromagnetic water softener is that a magnetic field around the water pipe causes calcium particles to clump together. Such a system consists of two coils wound around the water pipe with a gap between them.

The circuit driving them is often a high frequency oscillator that generates pulses of 15 kHz or so. As a result, large particles are formed, which pass through the water pipe and do not cling to the inside.

Thus, the electronic water softener operates by wrapping coils of wire around the incoming water main to pass a magnetic field through the water. This causes the calcium in the water to stay in solution, thereby bottling it up from clinging to taps and kettles. Also, the impact of electromagnetic flux makes the water physically soft as the magnetic flux breaks the hard molecules and makes it soft by nature.

Below is a visual summary of the process.

Most electronic descalers typically operate with two coils to increases the time for which the water is exposed to the electromagnetic waveform, but a few use only one coil.

Figure 2 Here is how electronic descalers operate with two coils or one coil. Source: Author

A quick inspection of the most common water softener circuits found on the web shows that the drive frequency is about 2 to 20 kHz in the 5- to 15-V amplitude range. The coils to be wound outside the pipe are just about 20- to 30-turn inductors made of 18 to 24 SWG insulated or copper wire.

It has also been noted that neither the material of the water pipe (PVC or metal) nor its diameter has a significant effect on the efficiency of the lime solver.

When I stumbled upon a blogpost from 2013, it felt like the perfect moment to explore the idea more deeply. This marks the beginning of a hands-on learning journey—less of a formal project and more of a series of small, practical experiments and functional blueprints.

The focus is not on making a polished product, but on picking up new skills and exploring where the process leads. So, after learning from several sources about how electronic water softeners work, I decided to give it a try.

The first step in my process involved developing a universal (and exploratory) driver circuit for the pipe coil(s). The outcome is shown below.

Figure 3 The schematic shows a driver circuit for the pipe coil. Source: Author

Below is the list of parts.

• C1 and C2: 470 uF/25 V
• C3: 1,000 uF/25 V
• D1: 1N4007
• L1: 470 uH/1 A
• IC1: MC34151

Note that the single-layer coil L2 on the 20-mm diameter PVC water pipe is made of around 60 turns of 18AWG insulated wire. The single-layer coil on pipe has an inductance of about 20 uH when measured with an LCR meter. The 470 uH drum core inductor L1 (empirically selected part) throttles the peak current through the pipe coil L2.

A single-channel MOSFET gate driver is adequate for IC1 in this setup; however, I opted for the MC34151 gate driver during prototyping as it was readily on hand. Next comes a bit different blueprint for the pipe coil driver.

To drive the pulse input of the pipe coil driver circuitry, an Arduino Uno was used (just for convenience) to generate a sweeping frequency between 500 Hz and 5 kHz (the adapted code is available upon request). Although selected without a specific technical justification, this empirically optimized range has demonstrated enhanced performance in some targeted zones.

At this stage, opting for a microcontroller-based oscillator or pulse generator is advisable to ensure scalability and facilitate future enhancements. That said, a solution using discrete components continues to be a valid choice (an adaptable textbook pointer is provided below).

Nevertheless, the setup ought to be capable of delivering a pulsed current that generates time-varying magnetic fields within the water pipe, thereby inducing an internal electric field. For optimal induction efficiency, a square-wave pulsed current is always advocated.

The experiment is still ongoing, and I am drawing a tentative conclusion at this stage. But for now, it’s your chance to dive in, experiment, and truly make it your own.
