Built a test jig for my home made USB to bench supply adapter

I have designed and built a test jig that will automatically test a small USB output for bench power supplies adapter called USBpwrME. The USBpwrME allows users to connect USB powered electronics to a power supply during test, evaluation troubleshooting etc.

Test jig in action

The test jig is built around the PIC18F27K22. This is my goto chip at the moment. It has a lot of configurable peripherals, ADC with really high resolution and a huge amount of memory for being a small MCU. And wide supply voltage range!

Test sequence will cover all the functions of the USB adapter with as few operator interactions as possible. One "funny" mistake i made during the design was not noticing that the relays i use has actually polarized coil so the pos/neg has to be connected in correct way to make the relay click. I missed this so i needed to hand modify all three relays.

Second mistake i made was actually a bit harder to foresee. One test that is performed is to invert the the input polarity to the USBpwrME to see that the polarity protection works. Well the design mistake was that the GND between the jig and the adapter is connected together thru the GND shield of the USB cables. So when the polarity switches the test jig short-circuits itself and restarts.

I solved this by adding in the test sequence when to actually connect the USB cables and performing the polarity test just before.

Even my eight year old son can operate it :) :)

Quite happy although with the result

Noise, India’s leading connected lifestyle brand, announces the launch of NoiseFit Halo 3, a bold, design, first round dial smartwatch crafted to seamlessly blend style, productivity and AI-powered utility. Design for those who refuse to compromise, Halo 3 combines the refined aesthetics of a classic dress watch with the intelligence and functionality of a modern smartwatch. It delivers what consumers have long sought: a timeless round-dial design paired with meaningful smart capabilities. Building on the Halo legacy, Halo 3 features a sculpted integrated-strap silhouette, a vibrant 1.43″ AMOLED display with 1000 nits brightness, and Noise AI Pro, a productivity-first AI ecosystem offering voice commands, voice recording and transcription, health insights, and personalised wallpapers. 

With Noise Vault for QR pass access, a customizable Smart Dashboard, one-tap health checks and up to 7 days of battery life, Halo 3 is built for the modern man who wants to make an impression, moving effortlessly from a boardroom meeting to a boarding gate, with a watch that transitions as fluidly as he does.

Noise AI Pro with Smart Productive Dashboard

At the core of Halo 3 lies Noise AI Pro, a productivity-first AI layer built for modern routines. Voice commands enable hands-free actions, morning briefs summarise sleep and activity insights, and AI Transcription transcribes voice notes into clean notes. Super Notifications refine alerts by surfacing contextual updates like OTPs, ride statuses and delivery notifications (Android supported). Complementing this intelligence is a customizable Smart Dashboard that supports up to five widgets,  from music control and AQI to sleep insights and hydration tracking, ensuring the most relevant information is always within reach.

Round-Dial Design with AMOLED Brilliance, built to command attention

NoiseFit Halo 3 features refined curves that flow into an integrated strap design, creating a cohesive, sculpted silhouette. Precision cuts along the dial edge add depth and character, while the 1.43” AMOLED display with 1000 nits brightness delivers striking clarity and effortless visibility across lighting conditions. Available in metal, leather and silicon strap options, Halo 3 adapts seamlessly from boardrooms to social settings, offering long-wear comfort without compromising on presence.

Noise Vault & Seamless Utility, scan and move

Halo 3 introduces Noise Vault, allowing users to store QR codes for flights, concerts, movies and more directly on the watch. Acting as a digital passbook, it enables seamless, hands-free scanning at entry points and boarding gates, reducing dependence on the phone during high-movement moments.

Health Insights & Week-Long Battery, built for uninterrupted days

The smartwatch supports one-tap heart rate, stress and SpO₂ monitoring alongside continuous tracking throughout the day. Backed by up to 7 days of battery life, Halo 3 ensures users stay informed and connected without frequent charging interruptions.

Price and Availability

Available in four elegant colours with strap options – Metal (Black) , Leather (Brown, Blue) & Silicon (Black),  the NoiseFit Halo 3 is live on sale, at an introductory price of 5,499 on gonoise.com, Amazon and Flipkart

Renesas Completes Acquisition of Irida Labs to Expand Vision AI Software Capabilities and Accelerates System-Level Vision Solutions

ELE Times - Fri, 05/08/2026 - 13:42

Renesas Electronics Corporation is a premier supplier of semiconductor solutions. Today, it announces that a subsidiary of Renesas has completed the acquisition of Irida Labs, a Greece-based company specialising in embedded software for AI-powered visual perception systems. The acquisition strengthens Renesas edge AI embedded processing offerings, a key secular growth area for Renesas. It also enables system-level solutions that integrate physical AI vision systems across industrial, robotics, smart city, IoT, agriculture and healthcare markets. As a part of Renesas’ digitalisation strategy, Irida Labs software and tools will be integrated into Renesas 365, a newly released platform that unifies electronics system development from discovery to development and lifecycle management.

While the demand for intelligent systems at the edge continues to soar across industries, developers must often overcome the growing complexity of AI system development. This includes the integration of power-constraint embedded processors and software, training, deploying AI models and addressing latency and security risks associated with data transmission. Vision AI software plays a critical role in interpreting and processing visual data from cameras and sensors widely used in industrial inspection, robotics guidance, in-cabin automotive sensing, traffic and infrastructure monitoring, smart retail analytics and safety and security systems.

The addition of Irida Labs to Renesas’ product portfolio addresses these emerging challenges. By combining Renesas’ AI-enabled RA microcontrollers (MCU) AND RZ microprocessors (MPU) with Irida Labs comprehensive tool suite and lightweight Vision AI software, Renesas can now delebier high performance, power-efficient edge AI solutions that are ready for deployment. Together, these capabilities reinforce Renesas’ progress towards fully integrated Vision AI system solutions.

Vassilis Tsagaris, CEO & Co-Founder of Irida Labs, added, “The joining of Irida Labs into Renesas marks an important milestone in our edge vision AI journey. By combining Irida Labs’ edge Vision AI expertise and our PerCV.ai software with Renesas hardware and global ecosystem, we open up exciting new opportunities to deliver meaningful impact on edge AI worldwide. I am proud of what the team has built, and genuinely excited to take it forward together with Renesas, turning our shared vision into reality.”

Before the acquisition, Renesas and Irida Labs collaborated as partners to develop solutions combining Irida Labs’ PerCV.ai software with Renesas’ RA and RZ devices. Bringing these capabilities in-house enables Renesas to deliver more tightly integrated solutions quickly. Renesas also plans to integrate Irida Labs software and tools into its newly introduced intelligent, open cloud-based development platform, Renesas 365.
