One time someone brought a salvaged Seraph (god knows how they got it) with a VDNI setup in it, and wanted us to repair the mech and replace the interface cockpit with a customer supplied standard cockpit from a Victor. For those of you who have not interacted with a Direct Neural Interface setup -- which I would assume is most y'all for obvious reasons -- the system actually runs all throughout the entire mech structure. Upon informing the customer that removing said equipment would entail:

• Basically stripping down all of the myomer and rewiring the whole musculature with standard wiring

• Reformatting all of the integrity sensors in the structure

• Reprogramming the gyro to talk to a neurohelmet (big job on its own)

• Reprogramming the entire targetting system

The customer asked if we could "just put the Victor cockpit in and piggyback the outputs into its consoles". The Victor cockpit would not fit at all either, since the Celestials seem to only have enough space for a cockpit the size of a bar fridge for some reason.

We eventually got a cockpit setup that would fit, at which point we had also figured out that the NONE of the modules would talk to any of our diagnostics equipment, let alone output anything readable to the cockpit displays. So we had to build a custom harness for whole thing, which involves manually tracing the entire mech's wiring from top to bottom, to figure out which wires going into the cockpit were connected to what components and sensors.

The entire mech runs on 3 different voltage systems, none of them are the same as standard Inner Sphere or even Clan systems, and so many of those god damn wires are duplexed BUS cables.

By the third month we were about ready to dump the thing out in the middle of nowhere and tipping Comstar off to its location, and telling the customer it got stolen.

Oh! And while we were trying to figure this absolute headfuck of a mech out, it was taking up one of our bays and we still had to keep up our standard amount of work output using only the other 3 bays, because this customer was a friend of the shop's owner so we were doing this as a "favour" to the guy.

Long story short if someone ever brings you a Blake mech and asks you to make it work, tell them to take it to a Comstar shop cause you really do not want to, I promise you it will make you want to die. What are you gonna do with it? Do you have ANY other mechs with a C3i computer that it will even be able to connect with? No you don't! Don't lie!

DIY Patient Monitor

It's been a while since I posted! In the last post I presented my DIY wireless ECG. Today, I want to follow up on that post. In the last two years I added more and more consumer medical devices and features to the ECG that one might call it a DIY patient monitor 😀

I recorded myself using it in this video. I deprived myself of oxygen and watched the result on the monitor. See all the alarms going off 🙂

The design is inspired by Philips Intellivue. The alarm sounds I took from their website 😉

In the rest of this post I want to discuss how I came to this result.

Devices

The DIY ECG from last post was a good basis (https://www.tumblr.com/medical89/650543279114469376/diy-wireless-ecg?source=share).

I got a BP with bluetooth capabilities (https://www.medisana.com/en/Health-control/Blood-pressure-monitor/BU-540-connect-Upper-arm-blood-pressure-monitor.html)

And a pulseoximeter with bluetooth (https://de.aliexpress.com/item/1005005549153646.html)

I reverse engineered (aka hacked) both of their bluethooth communication to get the live data into my website instead of their apps. I.e., get the BP after it was measured or retrieve the oxygen concentration every second. Then I extended my ECG application and it's web interface to include this information.

Alarms

The application now also includes alarms, just like a real patient monitor. Cyan alarms are triggered if a device is not connected correctly, red alarms if a vital value is outside of its limits!

Buttons

I also wired up the power button on the BP to my ECG so I can start it from the website using the BP button. When entering a number in the text field next to the button, the BP is taken automatically every x seconds 🙂

The shock button is wired up to a TENS unit and can give shocks.

I also made a program that can sync shocks and BP inflates to a video, but that's a story for another day!

Hope this was interesting for you and feel free to contact me to ask for more details 🙂

Halcon Memories of an Iterator

Something quick I whipped up before bed last night, some mild downpour spoilers. This takes place a little before rivulet.

Contains: angst, hurt/comfort, mild body horror, not much dialogue

Words: 883

Summary: Five Pebbles is reaching the end of his structure's life, he's angry at himself more than anything. He remembers what was good while he still can.

The hustle and bustle of everyday life reduced to still air, as though if the breeze were too strong for the weathered and weakened buildings would collapse.

The wind blew gently, a crisp warmth that carried the sun’s energy as though it were reaching for a hug. Dancing between ruined buildings, left behind by those who once lived there. The breeze yearned for what was missing, laughing children playing games, university students rushing to class, even someone taking a comforting walk on their way to work.

No vegetation touched the broken town, as if the thick presence of death around the city prevented any form of life.

Nothing remained, not a single tribe of scavenger walked the streets. Not a soul walked the outside of the superstructure, of his can.

Layers upon layers of dust, the once pale green pearl that had been carelessly discarded upon the structure’s surface had been covered in a thick film of ash and dirt. So aged and forgotten that no iterator would be able to decipher its contents.

The Echo that had once watched over his surface had seemed to vanish. Six Grains of Gravel, Mountains Abound. Though trapped in a state between transcendence and this dying world, their place on this dusty terrain sat empty for years.

The karma gate remained still, silent. Rust spilled onto the once-pristine metal of it, tainting it with the age of its surroundings. It had done well to keep the sickness out, to keep his sickness in.

Past blinking lights and buzzing interfaces. Unwilling to turn off for the last time like many of his others, they stayed on. Was it his stubbornness to become inactive, or did he still hold some will left in him? He doubted it was the latter.

Within the general systems bus, he sat in his chamber.

Five Pebbles sat on the tiled floors, and four of his last remaining neurons hovered above his form. His sunset-coloured cloak bunched up around his legs, red and blue wiring extended from his neck, tangling around him. Usually, he would find it cumbersome, to tidy them immediately. He seemed to lack the energy now, however.

In a pile on the ground, his puppet whimpered and trembled in discomfort, feeling the infection deep inside his system.

The puppet sat, knees to his chest. Surrounded by stacks upon stacks of his pearls, his eyes narrowed at seeing his reflection on their sparkling surfaces.

He could admit, he was far from being a vain iterator, he barely cared for his appearance. But seeing his pitiful figure here, hunched on the floor with a tattered cloak and sparkes flinging from his non-functional mechanical arm, binding him to the walls of this cursed place. He hated it.

He was a robot, an AI controlling a puppet. He should not be able to feel the growing lump in his throat, his glowing eyes felt heavy. He was artificial. Unable to cry even if he wanted to. It tore at his deepest circuitry. He felt like he wanted to scream. For as long as his puppet or broken hardware would allow.

Five Pebbled buried his face in his knees, fingers curling around his mechanical antenna. He wanted nothing more than to rip them from his temples. But he knew he couldn’t.

He cringed, screwing his eyes shut as he felt more of his infection, more of the rot seep into his core, eating away at the inside of his can. Eating away at his memories, eating away at him.

His bright eyes opened, studying his hand. The puppet’s delicate pink fingers dulled to a grey, glowing blue from between the plating of his digits. His sickness had started infecting his puppet, not that he could do anything about it except watch, regardless.

“I’m sorry, Moon,” his mechanical voice came out as little more than a whisper. “Everything I put you through, you were always so patient with me.”

He reached for a bright purple pearl, running his fingers along its surface. It played a tune, the tune of the city that sat atop his can.

“It was not your fault they left us here, abandoned us with their problems. I should not have been so hard on you. I wish I had listened to you sooner, big sister.”

Halcon Memories sung out within the chamber, Five Pebbles drummed his fingers to the beat.

“I do not know if you are even still operational if you are even still alive. But please, wait for me, wherever it is we go to when we die, please wait for me. I need to tell you how sorry I am.”

His eyes drifted to the several firey scratch marks over his puppet’s metallic flesh. He smiled, remembering the little combustible rodent that chose him. So angry at the world, like he once was, the little animal found comfort in him as he did them.

“You too, my citizen, I hope to see you too.”

Halcon Memories faded out, the song coming to a finish. Five Pebbles reached for the pearl, replaying the song. He started to forget about his worsening condition as he focused on the musical notes. In the moment, he was at peace, no longer angry at the world, as his creators. No longer angry at himself.

5 Common Mistakes in Battery Management Systems

There are a few common issues related to the time of adoption and usage of BMS that may affect longevity, safety, and efficiency of a battery pack. Here are five typical errors to avoid:

1. Inadequate Thermal Management

Mistake: Failing to adequately check and regulate the battery cells' temperature.

Consequence: Overheating brought on by poor thermal management might result in thermal runaway, lower battery efficiency, or a noticeably shorter battery life.

Solution: Make sure the Battery Management Systems (BMS) has several sensors for complete temperature monitoring, and when needed, combine it with an active heating or cooling system.

2. Ignoring Cell Balancing

Mistake: Not implementing cell balance in the battery pack or configuring it incorrectly.

Consequence: Ineffective cell balancing can cause individual cells to overcharge or undercharge, which can diminish the battery's total capacity and cause uneven wear and possibly damage to individual cells.

Solution: To ensure consistent charge levels in every cell, use a BMS with either passive or active cell balancing.

3. Overlooking BMS Compatibility

Mistake: Using a BMS that isn't entirely compatible with the battery chemistry or the battery pack's particular setup.

Consequence: Incompatibility can result in improper voltage limits, inappropriate protection, and even unsafe operating conditions.

Solution: Make the BMS specifically designed for the type of battery chemistry used (Lead Acid, Lithium-ion, etc.) and the type of battery pack layout series/parallel arrangement.

4. Inadequate Fault Detection and Diagnostics

Mistake: Not providing enough fault detection and diagnostic tools for the BMS.

Consequence: Faults like short circuits, cell failures, or wiring faults could go unreported without adequate fault detection, resulting in battery damage or dangerous situations.

Solution: Select a BMS (Battery Management Systems) that has advanced diagnostic and fault detection, data logging, real-time warning capability, and communications of problems with other systems or operators

5. Underestimating the Importance of Communication Protocols

Mistake: Integrating a BMS (Battery Management Systems) with other system components without using the proper communication standards.

Consequence: Inaccurate battery status reporting and other inefficiencies can result from poor communication, as might a complete system failure if vital information is not accurately exchanged with controllers or displays.

Solution: The BMS should be able to converse with and connect to the rest of the system: other vehicle control units, chargers, and user interfaces using the necessary protocols: CAN bus, I2C, etc.

Staying away from these common mistakes while selecting and setting a BMS enables you to ensure that your battery pack can serve for as long a time as possible safely and efficiently.

Lithion Power is a manufacturer of high-end Battery Management Systems that can realize maximum performance from any given battery while ensuring safety. BMS developed for electric vehicle applications, energy storage, and portable electronics are highly critical-they offer monitoring and protection with precision to extend the life of the battery and enhance its reliability.

Working on Sophias Story again :D

-> A little later, Sophia reached maintenance shaft [xy], where the main security system of the SD of the Abyss Chrusher was located. The light activated by a motion sensor flared up in cold white with a delay of a few seconds. Neon Xilkor tubes of the NX-6 series had this somewhat unpleasant habit, which the manufacturer Asterisk never rectified. Despite this, Hallinger-FTL continued to install them in all maintenance rooms of their ship series to this day. The Davar class in particular suffered from this fact, as it had a higher number of such areas due to its modular design. As a result, Sophia had only been able to recognise the large control cabinets and component racks by the myriad of flashing LEDs when she arrived. This sea of red, orange and green diodes, which greeted her auspiciously from the steel racks, secretly watched over the entire crew and ensured that the safety units of the individual SERAHs were working.

Now that the white light flooded the room, she saw it in its entirety, and with it the technology inside. In contrast to the blinking confusion of the Sevix control racks on the right side of the room, the Servagul control cabinets on her left, unusual for a Davar-class ship, emitted a soft green glow. The reason for this was that Servagul built light panels into the doors of their products, which no self-respecting shipbuilder needed. Such nice lighting did nothing but waste power unnecessarily. Sure, ships like the Abyss Chrusher might not lack power, but that was no reason to be so wasteful.

Shrugging her shoulders, the engineer lifted her tool and the testing device before taking them to the control cabinet labelled SUR-2, where she set them down. She unlocked the door with her CAM and the handle whirred out, allowing her to open the cabinet. Sophia sighed, pulled open the cupboard door and, coloured by the light from the front panel, saw another flood of flashing or glowing diodes emanating from the security register cards. It was a sight that filled the engineer with joy, because she had hardly been able to wait to get back into the bowels of the Abyss Chrusher, but the work that was to follow was rather dull. So she plugged her headphones into her CAM, put them in her ears and switched on an album by a band Liv had shown her a few days ago. A harsh guitar riff accompanied by the vocals of a woman singing in the language of the Marlan system rang out.

She then began checking the security tabs, which initially consisted of informing the SD-SERAH of her work via the control panel in the top frame of the device. In fact, Sophia was only slightly keen on an emergency lockout of the SD, even if she could override it with her system authorisations. Basically, you had to give Servagul and Sevix credit for the cleverness of their products. After all, the automatic security system, which according to Ela - unfortunately there were no plans on this subject - summarised one subsystem of the drive per cabinet in order to pass them on to SERAH in a bundle.

You could imagine the tabs and their subsystems as the nervous system of a body, which transmitted every pain of the machines to the consciousness or to an AI. SERAH then reported the information to the Abyss Chrusher's SAM, the ship's main AI, which ensured that appropriate action was taken. What the SERAH was to the SD, the SAM was to the entire ship.

Sophia pulled a small screwdriver from the side pocket on her left arm. She used it to loosen the two neck screws on the top and bottom of the front panel of each of the seven assemblies. She was then able to pull them out by the handle to insert them into the test device. This established a serial, wired connection with the fuse register in order to then interrogate the main function of the unit on the two circuit boards of the modules. For this purpose, the test device simulated a fault by sending a specific signal sequence via the bus interface. The module processed this within a few femtoseconds and signalled an alarm back to the test device. At least that's how it worked when everything was OK. The process only took a few blinks of the eye until the technical measurement results - such as resistance, time and induction values - appeared on the display of the test device. Confirmation of the success or failure of the analysis could then also be obtained.<-

Unleashing Automotive Intelligence: A Deep Dive into the New LAUNCH X431 CRP919X BT OBD2 Scanner

New LAUNCH X431 CRP919X BT OBD2 Scanner Automotive Diagnostic Tools Car CANFD DOIP ECU Coding Professional Scan

👍👍Buy now: https://youtu.be/s4sVIbJTV7s

🔥🔥 DISCOUNT: 62% 🔥🔥

In the ever-evolving world of automotive technology, the tools mechanics and enthusiasts use must constantly adapt to keep pace with increasingly complex vehicles. Gone are the days when a simple code reader sufficed. Modern cars, bristling with intricate electronic control units (ECUs) and high-speed communication networks, demand diagnostic tools with unparalleled depth and versatility. Enter the new LAUNCH X431 CRP919X BT OBD2 Scanner – a professional-grade automotive diagnostic tool that promises to revolutionize the way we interact with our vehicles, offering advanced features like CANFD, DOIP, and ECU Coding.

This blog post will explore what makes the LAUNCH X431 CRP919X BT a standout choice for workshops and serious DIYers, dissecting its core functionalities and highlighting its significance in the contemporary automotive landscape.

The Evolution of Automotive Diagnostics: Beyond Basic OBD2 For years, the term "OBD2 scanner" conjured images of simple devices that read generic trouble codes and maybe offered a handful of live data parameters. While essential, this basic functionality is now merely the tip of the iceberg. Modern vehicles employ sophisticated protocols and architectural designs that require diagnostic tools to be far more intelligent and adaptable.

The LAUNCH X431 CRP919X BT is not just an OBD2 scanner; it's a comprehensive diagnostic powerhouse. Running on Android 10.0 with a robust MTK chip, doubled memory (4G+64G), and a 6300mAh battery, it offers a user experience that is 5 times faster and smoother than previous generations. Its sleek design, intuitive interface, and wireless Bluetooth connectivity (via the new DBSCar VII VCI connector) provide unparalleled freedom and efficiency in the workshop. No more tangled cables or being tethered to the driver's seat – diagnose your vehicle from anywhere within a 33ft range.

Cutting-Edge Communication: CANFD and DOIP Explained Two of the most significant advancements in modern vehicle communication protocols are CANFD (Controller Area Network Flexible Data-rate) and DOIP (Diagnostics over Internet Protocol). The LAUNCH X431 CRP919X BT's support for these protocols is a major differentiator, future-proofing your diagnostic capabilities.

CANFD is an evolution of the traditional CAN bus protocol. While classic CAN was limited to a maximum data transfer rate of 1 Mbps and an 8-byte data payload, CANFD dramatically increases these limits. It can achieve speeds of up to 8 Mbps or higher and allows for data payloads of up to 64 bytes. This increased bandwidth and data capacity are crucial for modern vehicles equipped with advanced driver-assistance systems (ADAS), autonomous driving capabilities, and electric powertrains, which generate and process vast amounts of data in real-time. Without CANFD support, diagnosing these newer, data-heavy systems would be impossible. The CRP919X BT ensures you can communicate effectively with the latest GM vehicles from 2020 onwards, among others, that increasingly rely on this protocol.

DOIP (Diagnostics over Internet Protocol), on the other hand, revolutionizes diagnostic communication by leveraging Ethernet-based networks. Instead of proprietary wired connections, DOIP allows diagnostic tools to communicate with vehicle ECUs over an IP-based network. This brings several key advantages:

Higher Bandwidth: Ethernet offers significantly higher bandwidth than traditional automotive communication buses, enabling faster data transfers for complex diagnostic tasks, software updates, and firmware upgrades. Remote Diagnostics: With DOIP, diagnostics can potentially be performed remotely over an internet connection, offering greater flexibility and efficiency, particularly for fleet management or specialized workshops. Scalability: DOIP provides a more scalable and standardized approach to vehicle diagnostics, crucial for the ever-growing number of ECUs and interconnected systems in modern cars (e.g., BMW F and G Chassis, Jaguar, Land Rover from 2017 onwards, and Volvo from 2018 onwards). The LAUNCH X431 CRP919X BT's inclusion of CANFD and DOIP support signifies its readiness for the next generation of automotive technology, ensuring comprehensive compatibility with the latest and future vehicle models.

Unlocking Potential: ECU Coding and Bi-Directional Control Beyond reading and clearing codes, a truly professional diagnostic tool empowers technicians to interact with vehicle systems on a deeper level. The CRP919X BT excels in this regard with its ECU Coding and Bi-directional Control capabilities.

ECU Coding allows you to customize vehicle settings, activate hidden features, and adapt new components after replacement. For instance, you can:

Personalize vehicle settings for comfort and convenience (e.g., auto start/stop function, interior light duration). Match new ECUs or modules to the vehicle, ensuring proper functionality after a replacement. Perform component matching for various systems. Even retrofit features like a TPMS to older cars. The CRP919X BT supports online coding for popular brands like VW, Audi, and Skoda, and offline coding for VW, Audi, Skoda, Mercedes-Benz, BMW, Land Rover, Jaguar, Porsche, and Toyota, providing immense flexibility for customization and repair. Bi-directional Control, also known as Active Tests or Actuator Tests, takes diagnostics a step further. Instead of just passively reading data, this feature allows the technician to send commands to specific vehicle components and observe their response. This is invaluable for pinpointing the root cause of issues, as you can directly test the functionality of:

Fuel injectors Solenoids Cooling fans ABS pumps And many more actuators. This capability significantly reduces diagnostic time and guesswork, enabling faster and more accurate repairs.

Comprehensive Coverage and Advanced Service Functions The LAUNCH X431 CRP919X BT boasts impressive vehicle coverage, supporting over 10,000 vehicles worldwide, from passenger cars to 12V pickup trucks and SUVs produced between 1996 and 2025.

QMK Projects

Hello QMK Community,

I've been an amateur mechanical keyboard user for years and an even more amateur electrician for even longer. I had learned about the existence of a Dactyl Manuform keyboard and had to make one for myself. With a few trials and helpful guides I eventually made two pairs, one for work and one for home. I named them Enki and Namma after the Sumerian creation gods. They were made with Gatreon Green and Kaith White switches respectively.

Pictured: Wiring process top, Enki left, Namma right

I even went so far to make my own keyboard layout combining the "Workman" layout and the "M-system" layout to make a keyboard optimized for English and Japanese typing.

Pictured: Workman / M-system Hybrid Layout

All of these projects above would not be possible without QMK (Quantum Mechanical Keyboard) an open source firmware used in hobbyist mechanical keyboards. Despite all of that, QMK currently has no support for my next ambitions. There are two primary features I am looking for: -Analog Hall Effect Switches -PS/2 Support

The first feature I would like to implement is analog hall effect switch support. Hall effect switches are switches that utilize the "Hall effect". Basically, they are a sensor that can detect when a magnet is moving over them. In keyboards, this means you can create a switch that is literally just a magnet on a spring. This simplicity makes the switch very durable. These switches can even be analog meaning they can detect the intensity of a key press and be adjusted in software. The one downside for most consumers is that they are only offered as linear switches, in other words, switches with little or no click. Personally, this is not a downside because I'm looking to move to linear switches anyway.

Pictured: Hall effect sensor left, Hall effect process right

Hall effect switches already have support to a certain extent. Hall effect sensors can be digital instead of analog, meaning the switch can be used as a normal switch plugged in the normal way. I see this as wasted potential and will not be using these for my project. Only one analog Hall effect QMK keyboard exists to my knowledge, the Keychron Q1 HE. I do not intend to buy this keyboard but may reach out to Keychron to see how they pulled this off.

Pictured: Keychron Q1 HE

The second feature I want to implement is PS/2 support. I imagine very few of you know what I'm talking about, some of you think I'm trying to make a keyboard compatible with a 25 year old games console, and the ones who do know what I'm talking about probably think I'm crazy.

Pictured: PS/2 Port

Above is a PS/2 port, a standard introduced by IBM in 1987. Now I suspect the entire audience is on the same page of thinking I am nuts. Hear me out, there is a reason you can still find computer's made with this port today. When using this port with a keyboard or mouse, the device interfaces directly with the hardware of the machine. USB devices have a polling rate, they effectively send their data by waiting for the bus. With a PS/2 port, there is no waiting so the speed of data is dramatically increased. There are several other features exclusive to PS/2 but the latency decrease is my primary objective

Pictured: Passive PS/2 Adapter

Some of you may find a device like the one pictured above and think there is no need for this direct support, you can just plug the keyboard into this adapter and it will just work. You are wrong. Only certain keyboards play well with these adapters. There is a protocol built into a normal keyboard's firmware that can detect if it's plugged into an adapter like this. This protocol does not currently exist in QMK to my knowledge. My intention is to introduce this protocol into QMK's firmware for use with these passive adapters. This way, I don't need to introduce a new port to my existing keyboards or get PS/2 wires and plugs.

I'm intending to make another two keyboards with both of these new features named Gilgamesh and Enkidu because what good is a theme if you don't stick to it? I'll post updates as I continue along this journey and hope you are interested in how this project develops. If you have any insights or knowledge please feel free to reach out.

【step by step】Easyi3C Host I3C adapter (1)

Easyi3C is a leading supplier of embedded system tools that simplify the development and debugging of various communication protocols. The company offers a range of products designed to help engineers and developers use I3C/I2C , USB and MIPI, JEDEC, MCTP and other protocols more efficiently.

1. Basic Introduction

Easyi3C Host I3C adapter is a powerful and easy-to-use I3C and I2C host adapter produced by Easyi3C. It connects the computer to the downstream embedded system environment through the USB interface and adopts the advanced I3C and I2C protocol.

Based on the application programming interface (API) function and the Easyi3C Tower console graphical user interface (GUI) tool, combined with the Python development environment, the Easyi3C Host adapter greatly simplifies the development process of I3C/I2C chip testing and data transmission environment. It provides great convenience for AE engineers, FAE engineers, etc. to verify I3C/I2C chips. Simple verification can be done through the graphical console interface, which is easy to use and easy to learn. If you want to test more complex functions or perform automated testing, you can use the rich API functions provided by the manufacturer to quickly implement automated scripts in the Python development environment.

We know that I2C was invented by Philips Semiconductors in 1981, and its history is a bit old and mature. The I3C protocol I3C specification was originally released by in 2017. I3C is the abbreviation of improved internal integrated circuit, which is a 2-wire digital interface similar to I2C. It improves and optimizes the previously released I2C and SPI interfaces, solves the problem of slow I2C communication speed, and optimizes the shortcomings of SPI through four-wire connection. The I3C specification is managed by MIPI Alliance Inc. I3C also solves the problem of high power consumption of I2C. I3C becomes a low-power, low-cost and fast digital interface. It supports multi-point connection between host MCU and peripheral devices such as sensors and multi-master devices. Because the protocol is still very new, there are not many good tools on the market. The series of products launched by Easyi3C will fill this gap. The same interface supports I3C/I2C protocols at the same time, which is convenient for engineers to write automated scripts for chip protocol testing, shorten the product launch cycle, and help the company’s products win the competition.

Lexi Berg Takes Us "In So Deep" on New Single Lexi Berg plunges us willingly "In So Deep," her latest single offering a welcome submersion into the heady waters of shared existence. This London-based, Swedish-American artist wields a voice that carries its own weather system – there’s a satisfying rasp there, less a flaw, more like the unique grain in reclaimed timber, lending strength and character. The song itself claims indie pop territory, nodding respectfully to folk traditions, but there's a contemporary strangeness stirring beneath. https://open.spotify.com/album/5z1i1FijhVnw3B3YRFP8z0?si=coMfka6jR9OGqRoCMCkVyw Raw acoustic textures provide the grounding wires, familiar and warm. Yet, they’re intertwined with subtle electronic shimmers and currents, creating a sound that feels both rooted and curiously untethered. It's like finding an antique music box that somehow interfaces with your smartphone. Captivating, yes, and faintly psychedelic in the way a sudden change in atmospheric pressure can slightly alter your perception. The effect mirrors the song's heart: the overwhelming, delightful fog of deep connection, where sharing space – any space, doing anything or nothing – becomes the ultimate destination. [caption id="attachment_59481" align="alignnone" width="2000"] Lexi Berg Takes Us "In So Deep" on New Single[/caption] Berg maps the contentment found not in grand declarations, but in the quiet conspiracy of 'us'. Riding a bus, cooking a meal, weathering a storm – the lyrics suggest these transform into miniature pocket universes of joy when experienced together. That intimacy is the song’s gentle engine. Midway through, a particular blend of acoustic echo and processed vocal harmony sparked a bizarre flash of memory: the distinct, cool scent of petrichor rising from sunbaked earth just as the first drops of a summer storm hit. Odd, perhaps, but the song evokes that kind of specific, sensory richness found in unexpected moments. It’s a beautifully crafted piece, exploring closeness as a shield and a sanctuary. You emerge feeling wrapped in something comforting, yet still pondering its depths. When does profound connection stop being an escape from the world and start becoming a world entirely of its own?
