Hi electronics friends! I’ve been working on this project for a few months, and the 1.0 version of my DIY synthesizer is finally here! I documented the whole process on YouTube: 👉 https://youtu.be/B1KDbnlMJYE submitted by /u/Fearless_Theory2323 [link] [comments]

For anyone wondering what it is: It's an old Xilinx Spartan II FPGA that was cut from an old custom PCI board. It has been adapted to an prototype board. It's an 8 bit ISA prototype board, however I'm not going to make an ISA card from it. I just ran out of typical prototype boards. I am planning to use this old FPGA to help me make another homebrew computer (glue logic). I am planning this time to make homebrew on a dedicated PCB, so I want to have a playground with that FPGA with all pins reachable to experiment with it before. I could got an adapter, but I couldn't find one locally to get it quickly. This thing took me three days of work in my free time. So, yeah. It works! On last photo teh FPGA is programmed to blink the LED! The RPi Pico acts as JTAG programming cable submitted by /u/maniek-86 [link] [comments]

For many years, I have been using my IEEE alias e-mail address in the “From” line of outgoing messages and receiving replies back addressed to that alias. Recently, that doesn’t seem to work anymore. If I put ambertec@ieee.org into the “From” line, messages often do not get delivered, as in these three examples below.

Figure 1 Screenshots of several rejected emails when ambertec@ieee.org is used in the “From” field.

The techno-babble of these rejections is different in each case, but the end result is the same: My message was refused for delivery.

I can only reliably send messages now using jdunn4@optimum.net as the “From” entry because, in the interest of “security,” the “From” entry must now match the actual sending address. When I made them match in these three cases, all of the messages were successfully sent to their intended recipients.

This difficulty was first noticed a few months ago for one recipient of my messages, but this issue has spread like some kind of disease to other recipients as well. The utility of the IEEE alias itself has therefore been very much diminished.

India is now the biggest supplier of smartphones to the US, overtaking China, marking a momentous change in global manufacturing. According to research firm Canalys, cited by the PIB, the share of Indian smartphone imports into the US had abruptly shot up to 44% during April-June 2025, whereas it was meager 13% in the same quarter of the previous year. On the other hand, China saw its share plummeting to just around 25% from 61% in 2024.

Such an extraordinary development has been largely attributed to government interventions like Make in India and the PLI scheme, transforming India’s electronics sector into what it is today.

The Ministry of Electronics & IT recently spoke about the growth journey of India, pointing out its tremendous rise both in production and exports between 2014-15 and 2024-25. From ₹18,000 crore, mobile phone production soared to ₹5.45 lakh crore, while exports surged from just ₹1,500 crore to ₹2 lakh crore a 127-fold increase in exports.

Overall electronics production grew from ₹1.9 lakh crore to ₹11.3 lakh crore, a sixfold increase.

There were only two production units in 2014–15, and by 2024–25, the number had grown to 300 units a massive expansion.

The increase in smartphone exports from India to the United States, which now accounts for 44% of US smartphone imports, is a key factor driving this shift in global manufacturing.This rapid scaling of production, reduction in imports, and emergence as an alternate tech supply chain to China have been largely driven by Make in India and PLI initiatives.

The rise of India as the top exporter of smartphones to the US represents a significant change in the dynamics of global manufacturing. This change has altered the electronics landscape of the nation and is being fueled by strategic initiatives such as the Production Linked Incentive scheme and Make in India.

New Cadence Palladium Dynamic Power Analysis App enables designers of AI/ML chips and systems to create more energy-efficient designs and accelerate time to market

Cadence announced a significant leap forward in the power analysis of pre-silicon designs through its close collaboration with NVIDIA. Leveraging the advanced capabilities of the Cadence Palladium Z3 Enterprise Emulation Platform, utilizing the new Cadence Dynamic Power Analysis (DPA) App, Cadence and NVIDIA have achieved what was previously considered impossible: hardware accelerated dynamic power analysis of billion-gate AI designs, spanning billions of cycles within a few hours with up to 97 percent accuracy. This milestone enables semiconductor and systems developers targeting AI, machine learning (ML) and GPU-accelerated applications to design more energy-efficient systems and accelerate their time to market.

The massive complexity and computational requirements of today’s most advanced semiconductors and systems present a challenge for designers, who have until now been unable to accurately predict their power consumption under realistic conditions. Conventional power analysis tools cannot scale beyond a few hundred thousand cycles without requiring impractical timelines. In close collaboration with NVIDIA, Cadence has overcome these challenges through hardware-assisted power acceleration and parallel processing innovations, enabling previously unattainable precision across billions of cycles in early-stage designs.

“Cadence and NVIDIA are building on our long history of introducing transformative technologies developed through deep collaboration,” said Dhiraj Goswami, corporate vice president and general manager at Cadence. “This project redefined boundaries, processing billions of cycles in as few as two to three hours. This empowers customers to confidently meet aggressive performance and power targets and accelerate their time to silicon.”

“As the era of agentic AI and next-generation AI infrastructure rapidly evolves, engineers need sophisticated tools to design more energy-efficient solutions,” said Narendra Konda, vice president, Hardware Engineering at NVIDIA. “By combining NVIDIA’s accelerated computing expertise with Cadence’s EDA leadership, we’re advancing hardware-accelerated power profiling to enable more precise efficiency in accelerated computing platforms.”

The Palladium Z3 Platform uses the DPA App to accurately estimate power consumption under real-world workloads, allowing functionality, power usage and performance to be verified before tapeout, when the design can still be optimized. Especially useful in AI, ML and GPU-accelerated applications, early power modeling increases energy efficiency while avoiding delays from over- or under-designed semiconductors. Palladium DPA is integrated into the Cadence analysis and implementation solution to allow designers to address power estimation, reduction and signoff throughout the entire design process, resulting in the most efficient silicon and system designs possible.
