Sharp has built a state-of-the-art anechoic chamber in Japan to measure the performance of flat panel antennas for LEO and MEO satellites. Using the Compact Antenna Test Range (CATR) method, the chamber simulates long-distance communication conditions, such as those encountered in satellite communication, over a short physical distance. It is also capable of accommodating one of Japan’s largest antennas, with an aperture of up to 80 cm.

Designed with high-quality radio wave-absorbing materials on the ceiling, walls, and floor, and equipped with parabolic reflectors, the chamber suppresses unwanted reflections and measures performance over a short distance. While typical chambers require over 60 meters to test an 80-cm aperture antenna, Sharp’s CATR-based setup achieves accurate measurements over approximately 7 meters across a frequency range of 10 GHz to 40 GHz.

In addition to supporting Ku/Ka bands used for satellite communications, the anechoic chamber also accommodates measurements in the upper mid-band (FR3 6 GHz to 24 GHz), a potential frequency range for 6G deployment. The new chamber facility, launching this month, will enable testing and technical verification of various products, including next-generation smartphones.

Infineon has introduced 300-mm power GaN wafer technology within a scalable, high-volume manufacturing environment. The company notes that 300-mm wafers offer significant technological and efficiency advantages over 200-mm wafers, producing 2.3 times more chips per wafer due to the larger diameter.

Infineon manufactured 300-mm GaN wafers on an integrated pilot line in its existing 300-mm silicon production facility in Villach, Austria. The company is drawing on its expertise in 300-mm silicon and 200-mm GaN production and plans to scale GaN capacity according to market demand.

A key advantage of 300-mm GaN technology is its compatibility with existing 300-mm silicon manufacturing equipment, as the production processes for gallium nitride and silicon are quite similar. Once fully scaled, 300-mm GaN production is expected to achieve cost parity with silicon at the RDS(on) level, enabling comparable costs between Si and GaN products.

Infineon will present its 300-mm GaN wafers at the electronica trade show in November 2024 in Munich, Germany.

The highly anticipated Bluetooth 6.0 specification is here, and one of its most notable features is the addition of channel sounding, a two-way ranging technique between two Bluetooth Low Energy (LE) devices. While Bluetooth LE is known for its low power consumption and cost effectiveness, it isn’t an optimum solution for reliable and accurate ranging.

Bluetooth Channel Sounding addresses these shortcomings by improving reliability and accuracy with distance measurement capabilities. That will significantly enhance high-volume applications such as personal item tags and key fobs, where presence detection and proximity sensing are crucial. Channel Sounding can be integrated into Bluetooth devices using a single antenna without requiring significant hardware modifications.

What’s Bluetooth Channel Sounding

Bluetooth Channel Sounding—a new protocol stack designed to enable secure and precise distance measurement between two Bluetooth LE-connected devices—unlocks a world of possibilities for embedded developers. It enables Bluetooth received signal strength indicator (RSSI) to open the door for a new wave of applications in localization and proximity awareness.

Localization applications like pet and asset trackers utilize locator devices to find the exact position of a tracking device. Next, proximity awareness applications such as smart locks and keyless entry systems utilize enhanced security features to restrict and control access to secure spaces and systems.

So far, Bluetooth RSSI has relied on estimations to determine location, which leads to issues like multipath and obstruction. That, in turn, significantly reduces accuracy. Bluetooth Channel Sounding addresses this by improving accuracy to the sub-meter level. “The Bluetooth SIG’s adoption of Channel Sounding significantly enhances the precision of previous Bluetooth distance measuring techniques and encourages innovation across the Bluetooth device ecosystem.,” said Øyvind Strøm, EVP of BU Short Range at Nordic Semiconductor.

Security is of utmost importance to ensure that no unauthorized user can access the network. Channel Sounding incorporates robust security features to protect against tampering and man-in-the-middle (MITM) attacks. That’s crucial in applications like smart door locks, home appliances, and Find My solutions. For instance, Channel Sounding ensures lock only opens when the authorized device is within a certain distance.

How it works

Bluetooth Channel Sounding uses two proven ranging methods—phase-based ranging (PBR) and round-trip time (RTT)—to deliver true distance awareness between Bluetooth-connected devices. The connected devices use PBR, RTT, or both to coordinate ranging data between up to 72 channels within the 2.4 GHz spectrum and use one to four antenna paths between the two connected devices.

PBR utilizes the difference between the phase of the transmitted and received signal to calculate the distance between the initiator and reflector devices. It compares the phase difference between these devices to accurately measure the distance between them. An initiator device sends a signal to a reflector device, which returns the signal, and this process is repeated across multiple frequencies.

In RTT, the secondary ranging method, an initiator device sends cryptographically scrambled packets to a reflector device, which returns the packets. Next, the distance between the devices is calculated based on the time the packets traveled back and forth.

RTT can be used to verify and cross-check the PBR measurements. This cross-verification process helps detect anomalies and ensure applications are secure. For instance, it serves as a countermeasure against sophisticated man-in-the-middle attacks.

True location awareness

Channel Sounding is expected to be widely adopted in mobile phones and a broad range of products such as Bluetooth mice, keyboards, and game controllers. Then there are Find My applications—Bluetooth tags attached to personal items such as keys, wallets, backpacks, and luggage—where developers can add true distance awareness to make it easier and quicker for users to locate lost items.

After Bluetooth SIG’s adoption of Channel Sounding as part of Bluetooth 6.0, Nordic Semiconductor has announced support for the technology in its forthcoming nRF54L and nRF54H Series RF chips. Silicon Labs has also announced the integration of this technology in its xG24 wireless chips and antenna hardware solutions.

Channel Sounding technology in Bluetooth 6.0 marks a significant step in the evolution of modern wireless, and its true wireless awareness is expected to unlock new use cases while optimizing existing ones. As Ross Sabolcik, senior VP of the Industrial and Commercial Business Unit at Silicon Labs, puts it, in a world where location awareness is critical, Channel Sounding revolutionizes proximity and location capabilities, propelling Bluetooth technology into a new era.

This printer pissed me off. Screw him. I spent so much money on this thing. Print head. $250. Ink refilling kit and ink cartridges. $100. Twice. Ink, ink and more ink. This fucking thing takes 8 ink cartridges! Bought 13x19 large format ink jet photo paper…couldn’t use because the print head SUCKS! AGAIN! Bought another print head from Ali Express $160. It’s used and not new! And inconsistent print quality. So I did what every sane person would do. I took that thing and ripped it to shreds. I’m redacting the make and model of this fucking thing, because I don’t really want to shit on this brand. It’s a good brand; it’s just my situation that sucks. I’m part of the reason why this printer sucks, not the brand. Being cheap and all, buying print heads from Ali Express, ink and refillable cartridges from eBay. It’s because the ink cartridges are insanely expensive! I wasted an entire set of manufacturers ink cartridges (8 of these cunt cartridges!) from cleaning the fucking print head! That’s why I bought cheap refillable ink from eBay. Then the print heads decided to go on vacation, and now we’re here. So fuck it. I tore that shit apart, and from the magic of ESP32 modules, H-Bridge L298N motor controllers, and a little bit of code, I’m turning this thing into something even more useless and retarded. Because I’m mad. And, because I really hate throwing stupid shit like this in the trash. First order of the day. Taking that SMPS power supply that came with the thing and fucking it up. Cracked the case open, plugged it in, force enabled the output, and putting it on an electronic DC load and driving it hard. The output is rated for 32v 0.7A. Screw that. With the DC load, I squeezed out 32v at 5 amps. 125mv RMS ripple at full load is crap, but I don’t care. As long as I can overvolt its fucking motors with using the original power supply, I’m happy. Doing my best to not contribute to the earths eCycle waste issue by repurposing most components from this printer to make something even stupider and useless. Reduce, Reuse, and Recycle motherfucker. One good thing is that the thermal cutoff works; power supply took a shit at 80° C. I freeze sprayed that bitch until it turned back on. Then continued to make it draw 32v 5 amps. Thermal cutoff keeps tripping; that’s ok…I have lots of freeze spray to wake his ass up. I mean, I have to make sure the power supply that came with this thing can handle the currents I plan on delivering to the 4 DC motors in this thing. Stay tuned to what other ridiculous useless piece of shit machine I can turn this thing into. submitted by /u/Asuntofantunatu [link] [comments]

I recently added a 6 channel sequencer in a drawer under the rack to allow on-the-fly edits of all the drum parts in one place. The control module on the left has an arduino that handles all the preset patterns, functions, and the chain of shift-registers to keep track of all the buttons and LED’s. The sequencer uses a couple CD4017 counters and some diode logic to generate the control signals for the drums. The drum board is made up of several bridged T filters and some white noise that are combined and fed to an output mixer. The spaghetti inside is (hopefully) temporary until I can figure out a better system to wire everything together. submitted by /u/jellzey [link] [comments]
