The ad hoc group “Shortwave Modernization Coalition” petitioned the Federal Communications Commission (FCC) to allow data communications on multiple bands within the HF 2 – 25 MHz range with up to 20 KW, including in bands immediately adjacent to spectrum allocated to the Amateur Radio Service.
We benchmarked the deep learning performance of the latest NVIDIA RTX 3090 GPU.
Listen to WWV announcement recorded 0008UTC 11/4/2021 from WWV 10MHz broadcast, receiver IC-7300 13.7km from the station.
Purism makes premium phones, laptops, mini PCs and servers running free software on PureOS. Purism products respect people's privacy and freedom while protecting their security.
We demonstrate that layered spatial light modulators (SLMs), subject to fixed lateral displacements and refreshed at staggered intervals, can synthesize images with greater spatiotemporal resolution than that afforded by any single SLM used in their construction. Dubbed cascaded displays, such architectures enable…
How Ouster OS1 sensors create 3D HD maps, demonstrated by scanning San Francisco's iconic Ferry Building.
We’re very happy to announce that the source code of the real-time operating system (RTOS) powering the Arduino 101 and Genuino 101 is now available for
Why head to the store when you could simply create your outfits right at home with the touch of a button? That’s the idea behind London-based startup
Explains features that make it easy to program in QED-Forth, including the interactive debugger, floating point mathematics, heap memory manager, arrays and matrices, structures, and the multitasking executive.
Today, Arm announced that the first silicon supporting the Morello prototype architecture, a research project led by Arm, Microsoft, University of Cambridge and others, is now available on a limited run of demonstration boards, which are being shipped from today to industry partners for testing. Morello is the first…
Scientists have discovered a group of materials which could pave the way for a new generation of high-efficiency lighting, solving a quandary which has inhibited the performance of display technology for decades. The development of energy saving concepts in display and lighting applications is a major focus of…

The Qualcomm Centriq 2400 has launched! Here are the details...
TL;DR : we reproduced Denis Andzakovic’s proof-of-concept showing that it is possible to read and write data from a BitLocker-protected device (for instance, a stolen laptop) by sniffing the TPM key from the LCP bus.
This tutorial will walk you through building a 3x5 LED matrix controlled by a Raspberry Pi Pico using tscircuit.
ByteShape's full ShapeLearn release of Qwen 3.8 27B: five GGUF models on the quality-speed frontier across six GPUs. GPU-5 is the default wherever it fits, at 99.63% of BF16. GPU-4 stays very competitive in a much smaller file.
Solar engineers from UNSW's Australian Centre for Advanced Photovoltaics have set a new world-record in solar energy efficiency, achieving an electricity conversion rate of over 40%.
When we hear about ML - whether it’s about machines learning to play Go or computers generating plausible human language - we often think about deep learning.
A community and blog for embedded software makers
A detailed tutorial on DDR4 SDRAM Initialization, Training and Calibration. Exploring topics such as Read/Write Training, ZQ Calibration, Vref Training, Read Centering, Write Centering, Write Leveling and Periodic Calibration.
Grab your biggest mug of coffee and learn how the open-source programming language Rust supercharges our development time of the breakthrough Sonair 3D ultrasonic sensor. Claim to fame: Sonair is on track to be among the first to deploy a safety-certified Rust implementation.
I modified an Easy Bake Oven to run off USB-C. The obvious question is "Why?", but I prefer to ask, "Why Not?". The USB-C spec allows for 100 Watts of power to be transferred through the connector, and that is the power rating for the oven, so it should work.
A zinc-air microbattery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines.
In 2022 a consortium of companies ran an international competition, called the ZPrize, to advance the state of the art in “zero-knowledge” cryptography. We d...
Maker Harry was inspired by Handle, Boston Dynamics' research robot, yo build his own mini version named MABEL.
