hey i read your headcanon about bi-hans father pressuring him and abusing Bi-han What if Bi-han, Kuai ans tomas reunite and they remember their father while Kuai Liang and Tomas are talking good about their father. What if bi-han snaps and tells them everything his father has done to him like from the scars to the impoact on his mental Health affect.

I just know Bi-han wouldn't be able to hold everything in anymore and just let it all out. Especially if it's after the Mk1 storyline (I want them to be NORMAL BROTHERS, so I'm gonna ignore canon :]) and Bi-han experienced life without them, even for just a brief time, and now he just wants them to know what he truly went through when dealing with their father. How it hurts him to see them put their dad on this pedestal and essentially glorify this man. He just wants his family back.

I think Kuai and Tomas would let him get everything out there. Though I do think they would be a little hesitant about believing Bi-han. Since ya know, their dad was so good to THEM. But then Bi-han would show them the scars, how he was treated as the next heir and how horrible it was when he didn't meet expectations. KUAI AND TOMAS WOULD SIT AND LISTEN BECAUSE THEY ARE GOOD BROTHERS!!! Despite how Bi-han has treated them in the past. I'd like to think this is one of the very few times they see Bi-han cry (my dude was the oldest, he probably sat in a closet to cry or berated himself so much cause "men don't cry" BABE THAT IS NOT TRUE PLS DONT HOLD IN YOUR EMOTIONS) AND THEN THEY HAVE A SENTIMENTAL MOMENT AND GO HOME AND HAVE A NICE WARM FAMILY DINNER-

Practical RF Design Manual

[Practical RF Design Manual by Doug DeMaw (Milton F "Doug" DeMaw). 1997. MFJ Publishing. 2nd Edition 1997 : 246 pages. ISBN 1-891237-00-4]

For many years I was an amateur radio - "ham radio" - operator, beginning when I was 13 years old and going up until I was about 40 years old. For those who are interested, my call sign was WA6FEB and I held an Extra Class ham radio license (this is the highest classification). My fascination with radio was fostered by my step-father, the late Sam Martin (WB6WZN, later N7TBV), who had learned his electronics and radio theory while serving in the US Navy.

Sam had many years’ worth of a magazine called QST, which was one of the premier journals available for ham radio enthusiasts. Doug DeMaw, the author of the book under review here, was a prolific contributor to QST and to other ham radio publications. I was (and remain) a huge fan of his writings, especially his transmitter and receiver projects for ham radio folks.

What I did not know then, but have come to learn, is that DeMaw was truly a world-class electrical and electronic engineer. He was known to much of the world as a ham radio person first and foremost, but he was a professional engineer who had an extraordinarily broad grasp of all aspects of radio transmission and reception, covering all power levels from the very tiny (what we in the ham radio community called QRP, or low-power, operation, usually less than 1 watt) to the industrial (the 50,000-watt and 100,000-watt “clear channel” broadcasts from commercial radio stations, for example). DeMaw was well-versed in design considerations spanning operating frequencies from the US AM broadcast band (560 KHz to 1600 KHz) all the way up to the UHF range (where television broadcast channel 14 begins in the US, or around 470 MHz and beyond). His knowledge went beyond component-level design of devices to include the design and tuning of antennas and other auxiliary devices to aid in the radio experience.

All of this knowledge is subsumed under the aegis of RF - radio frequency. RF in modern terms is usually linked to RF ID chips, which are becoming quite common in scenarios that require tracking (such as shipment packages), but this is a very restricted window into the RF world. To really see just how vast an enterprise RF electronics is, one might consult this book.

This volume is truly a gem. I dearly wish I had access to it back in the early 1970s when I was first getting into radio. It would have illuminated a lot of practical design issues for me, especially on the design of receivers. Receivers are generally more complicated and finicky than transmitters – it’s easier to generate radio energy and cast it out into the universe than it is to gather it in and make sense of it. This book leads the reader through 7 broad-based topics and roughly 40 overall subsections within those topics, starting with transmitter and receiver fundamentals and leading the reader through considerations related to power regulation, signal quality, the use of different types of components for different frequencies of operation and different power levels, and so on.

Unlike much of DeMaw’s writing with which I had been previously acquainted, this book is definitely not a book for someone looking to do a home project. There are no comprehensive instructions on assembling or testing transmitters, receivers, or other associated machinery. This book is written for a true engineer who wants to become familiar with many (most) of the gotchas that accompany real in-the-trenches electronic engineering work. And in this vein, this book is as useful to a professional radio engineer (such as someone who is the engineer-in-charge at a radio or television station, for instance) as it is to a radio hobbyist. It is also not the sort of book from which to learn first principles of electronics; for this, there are many more suitable books that introduce electronics at the most elementary level (Ohm’s Law, Kirchhoff’s Law, how vacuum tubes and transistors work, what makes oscillators work, and so on). This book assumes that the reader already has some engineering skin in the game, as the saying goes.

Whom would I recommend this book to? Anyone who wishes to know something about electronics that precedes the modern all-digital era where whole systems are embedded on integrated circuit (IC) chips. While those circuits may make for easier and more controlled design, they take away a lot of the learning, guesswork, and outright fun of figuring these things out for yourself. DeMaw’s work hearkens back to what many of us current and former ham radio people think of as a sort of golden era of communications – a time before cell phones and before email.

A couple of comments about the text itself:

There are some typos both in the text and on the many diagrams. For the most part these are easy to spot if you are already versed in basic electronics, but they would be profoundly confusing to someone who doesn’t know what they’re looking at. Anyone who doesn’t know how to read a basic schematic diagram of a circuit will not find this volume very helpful.

Bearing in mind that some of the material in this book dates to the 1970s and 1980s, it is possible that some of the actual components cited in the text no longer exist or are not easily available. Happily, the author describes them in sufficient detail that a modern engineer or hobbyist can find current components whose characteristics match what DeMaw had at his disposal when the book was written. DeMaw was fairly fastidious about describing the important pieces of each circuit or circuit fragment in the book. One needs but to pay attention to the text to make the connection.

I was delighted to read through this volume. I am not currently an active hobbyist, but as I near retirement age, I am giving a return to ham radio serious thought. With that in mind, this book will be an invaluable title in my collection when I once again wield a soldering iron and set out to make some more home-brew radio equipment as I did so many years ago.

RFID Protector for wallet

Peace of Mind in a Slim Package

In today's digital world, protecting your personal information is more important than ever. That's where RFID-blocking wallets come in. I recently purchased an RFID protector for my wallet, and I'm impressed with the added security it provides without any bulk.

What is an RFID protector and why do I need one?

RFID stands for Radio-Frequency Identification. RFID chips are embedded in many contactless cards, including credit cards, debit cards, and even passports. While RFID technology offers convenience, it also poses a security risk. Thieves can potentially steal your information from these cards using RFID scanners if they get close enough.

An RFID protector is a thin sleeve or lining that blocks RFID signals. This prevents scanners from reading your card information, offering an extra layer of security for your personal and financial data.

My experience with an RFID protector

I opted for a slim, sleeve-like protector made from durable fabric. It easily slides into the card compartment of my wallet without adding any noticeable bulk. I can still comfortably fit all my cards and cash without feeling like I'm carrying around a brick.

Since using the protector, I have peace of mind knowing my cards are shielded from potential RFID skimming. It's a small investment that provides significant security benefits.

Additional considerations

While RFID protectors offer excellent protection, it's important to remember they're not a foolproof security measure. For maximum security, it's always advisable to be vigilant and aware of your surroundings, especially in crowded places.

Overall, I highly recommend using an RFID protector for your wallet. It's a simple and effective way to safeguard your personal information without sacrificing convenience. With a protector, you can enjoy the benefits of contactless cards while minimizing the risk of electronic theft.

Headcanon that there’s a coming of age tradition for sand pups (Zone-born Killjoys) where when they turn ten they get a stick and poke of a cactus somewhere on their body. It’s a huge thing for them, because as one can imagine it’s not easy for young children to grow up in The Zones. If a sand pup gets to that age, it’s something to be celebrated.

Defined as “non-surgical lifting,” it is based on the emission of completely painless radio waves; these generate heat, and when in contact with the skin, they can stimulate fibroblasts and the production of new collagen, elastin, and hyaluronic acid by the epidermis. 🔝

The thermal shock that our body undergoes when coming into contact with the heat emitted by the electromagnetic waves stimulates vasodilation, which in turn promotes and improves blood circulation, consequently reducing cellulite and the unsightly orange peel effect, localized fat, and fluid retention. 👏🏻✨
