Bluetooth trackers and GPS trackers serve similar purposes but operate in different ways and have distinct features:
Bluetooth Tracker:
Range: Bluetooth trackers typically have a shorter range, usually around 100 feet indoors and up to 300 feet outdoors. The range can vary depending on the model and the environment.
Functionality: They rely on Bluetooth technology to connect to a smartphone or other compatible device. Users can track the location of the item to which the tracker is attached using a mobile app.
Battery Life: Battery life is usually longer compared to GPS trackers since they have a smaller range and don't require constant communication with satellites. Some Bluetooth trackers come with replaceable batteries, while others have rechargeable ones.
Accuracy: They are less accurate in pinpointing the exact location compared to GPS trackers. Bluetooth trackers provide a general idea of the item's location based on the last known connection with the smartphone.

Trick or treat!
Watching Izuku tug at the hood of his limited edition Golden Age All Might hoodie with his too big black gloves making his fingers clumsier than usual, shifting and reshifting the fabric to stop it covering his eyes or set the antenna at the right angle so they didn’t flop over too badly to one side, and listening to him stammer, backtrack, and lapse into mumbling at times as he tried to answer even the most straightforward and innocuous of media questions (“And what is your costume?”) asked of every hero whose attention could be nabbed on their way into the Put Your Hands Up and SCREAM Happy Haunted Hero Halloween Bash, it was difficult to see why villains found Deku so intimidating. At least the way he kept biting the already chapped spot on his lip and worrying the skin like nervous habit was covered by the black medical mask he wore.
 The Happy Haunted Hero Halloween Bash was part exclusive party of the year, part place where regrets and tomorrow’s tabloid headlines were soon to be born if you didn’t fly or get a car out of there in time, part televised entertainment special and charity drive where top heroes would be spinning the wheel to perform tricks for or hand out treats to top donors to the cause of the year early on in the night before the cameras turned of and the real party started, but all hosted by Present Mic. And it was Izuku’s first year. He wanted to make an impression. Hopefully a good one. Perhaps, playing it safe and going as Iron Might or a ghost (Nice, normal, innocuous classic ghost) like he almost had could have served that purpose better, looked good enough in pictures but proved unremarkable enough that the focus would be on Izuku himself–though, maybe that would have just been more pressure to constantly watch what he was saying and make sure he was funny and charming enough when he still rarely felt like either. 
“Why The Crawler? You are aware he’s regarded by some as a criminal menace. Do you think it’s appropriate for a top fifteen hero to be dressed as a former vigilante?”
Hmm. The questions were getting more complicated though. 
Izuku tried to keep his chin up and tone upbeat but not flippant. Shoulders back to project confidence. No more playing with his hoodie. It was easier said than done.  “My feelings about vigilantism have changed a lot over the years, especially since…” One sentence in and he already found himself stopping himself short. “ Well, you may have seen some of the pictures and video of my own stint as an unauthorized hero before the war…though on the other hand I suppose that wasn’t quite the same since I at least had my provisional license and I was in close contact with the pro-heroes…” He took a deep breath to counsel himself to keep his answer more focused. “But that’s beside the point. I know public sentiment towards The Crawler and other vigilantes is still mixed even now, and the law’s side is even more complicated, but…he fought to protect those that couldn’t fight themselves and protected those who nobody else was protecting and that makes him a hero in my book. Plus, it’s just a fun costume and not too overdone. I hope you’ll give me some grace here…and my partner too, as he’s dressed as an even more controversial figure.”
Izuku punctuated his last words by wrapping an arm around his boyfriend and hero partner–an arm that quickly dropped lower from shoulder to back to possessive fingers wrapped around a hip as if Izuku’s hand was magnetized, finding Kacchan’s small waist exposed and emphasized more than usual in the skin tight black leotard too much of a temptation (which it was, and Kacchan should have been grateful that was the only temptation that Izuku was willing to give into in front of the press, when the explosive hero’s sullenly crossed arms pushed his pecs enough together to make the heart shaped cutout on his chest more risque than it had ever been on the original costume of the vigilante Dynamight was emulating. 
“I’ll never forgive you, nerd.” Kacchan growled under his breath as more pictures were snapped of the two of them. The pink pigtails on his Pop Step wig were already starting to droop. 
“Yes, you will.” Izuku hummed back, cheerfulness already returning. He gave the press line a wave that signaled that they were moving on and angled carefully as he turned to walk away, arm still around Kacchan’s waist, trying to cover as much of the camera line of sight with his own body as he could as the two of them retreated. He had thought a lot about what the Pop Step costume would look like from the back (And so had Kacchan. That was how Izuku convinced him of the couple’s costume. They would spar with the stakes being that whoever was pinned first for over three seconds would be Pop Step and whoever pinned them would be The Crawler. Kacchan was really confident in his own abilities. Izuku loved that about him. Confidence just wasn’t always enough though when Izuku was motivated too). He hadn’t thought through other people seeing the costume from the back though, and photographing Kacchan from the back…or how he might, and certainly would, need to worry about that even after the press cameras and live streamed parts of the evening were over. 
Pop Step was going to have to be an in-apartment only costume going forward.
Izuku still didn’t regret it though.
“Kacchan, you look so…” He sighed dreamily and didn’t even try to finish his sentence or control his blush.
“I swear, if you call me cute, I’ll blow your face off.”
“No. Bouncy,” Izuku giggled as they walked into the venue and fully left the media behind, at least for the moment, deciding to finish the thought after all. Danger sense stayed dormant, even after a wisp of blackwhip shot out to ruffle the back of Kacchan’s skirt, only to dissipate the moment after when Kacchan snarled and whirled around to try and fight the semi-tangible. 
“I’ll kill you,” Kacchan continued to threaten him, no bite in it this time.
“I’ll give you my hoodie so you don’t get cold,” Izuku offered.
The fire in Katsuki’s eyes intensified instead of dying down to the smolder Izuku expected. “I’m not wussing out. A deal is a deal. No complaining. No covering up. The full Pop Step experience. Let’s get some drinks and I’ll start singing and shit too.” He balled his fists in determination.
Izuku was going to argue that there was no weakness in taking the hoodie–especially when he was pretty sure he just saw Hawks’ wings flare from across the room (They were dyed white tonight and Hawks was wearing a halo and a haphazardly draped toga, which was cute when taken together with the devil horns Endeavor was wearing, but Izuku, uncharitably, didn’t think Hawks was reacting to anything Endeavor had said) but his attention was diverted by Shoto waving both arms at them to flag Izuku and Katsuki down. Not that Shoto was easy to recognize in a long black wig, a short white dress and blazer, and a visor that covered his eyes. Izuku almost didn’t recognize the costume, much less the man, but once he figured out one, the other was a certainty. 
“What the fuck are you doing, Icy Hot?” Kacchan sighed exasperatedly.
“Makoto Tsukauchi. Don’t tell me you already have one for the group costume.”  Shoto was a shade too earnest to be pulling a Halloween trick–though Izuku and Katsuki were two of the only people alive who could read the shades of difference in his ever placid delivery.
Izuku neither had the heart to tell his friend that Pop Step and The Crawler were supposed to be a couple costume or to regret telling Shoto his plans in the first place. Group costumes would be fun. He did feel a bit out of place now being the only one without a skirt though.
“Why not Knuckleduster? He was a Naruhata vigilante.” Izuku pointed out. 
“You know why, nerd.” Kacchan didn’t elaborate further.
Any uncomfortable moment was put off by their old homeroom teacher, Aizawa, being the next to greet them. He looked the three of them up and down, narrowed his eyes particularly at Izuku, huffed a simple yet puzzling, “No,” and then walked away.
“Sensei?” Izuku called after him.
“I need a drink if the problem kids are combining.”

Putting a headphone jack in a Fairphone 4
TLDR with this procedure you sacrifice the lower loudspeaker, but the upper one will still behave as normal. Calls and other audio seem to work just fine. There is some interference from internals that gets picked up by amplified speakers, I'm sure there's a way to filter it, this is mainly a proof of concept. This is not really a guide and I do not guarantee anything at all.
I really liked my Fairphone 4 except that it didn't have a 3.5mm jack like normal phones used to have. And my car has never heard of Bluetooth. So I started joking about drilling a hole in it.
Tumblr media
I found this green TRS jack on a USB DAC and found it would fit inside. I took this photo with a DSi camera. Originally I thought I might be able to fit both the jack and the speaker, and I had this elaborate plan to make a cut in the mainboard and move the vibrating motor elsewhere,
Tumblr media
but decided against it because I had no idea what losing that one contact would do. I did a test and found no major issues with removing the bottom loudspeaker. If I needed the phone to be loud, I'd hook something else up anyway. I bought a second loudspeaker and horrendously dissected it.
Tumblr media
I used a knife. If you do this you should absolutely use a dremel tool and not a knife. Unless you don't have a dremel tool
The plan is, remove the speaker part. You do not have to completely de-laminate the two layers of plastic. Just this section of the bottom layer. The top layer has pretty colors and conductive tape and contacts for mysterious purposes. Maybe antenna.
Tumblr media
Next, you must drill the hole. We're not quite sure what the case is made of, but it probably involves aluminum. I had a drill press and clamps, but I went to my friend's house. He doesn't have clamps or many drill bits, but he knows metal. The jack barrel was like 5.1mm in outer diameter, and after lamenting that all our bits were in imperial, we settled on a 7/32". We removed all components from the chassis including mainboard and screen before drilling.
Here, we went for a hole that was centered on the middle hole of the speaker grill. However, if you do this, you will need to also remove some more metal, because the jack will need to be kind of submerged in the floor. We also had to sand down one side of the jack paper thin to make it sit flat against the back of the screen module. In hindsight, I should have marked where the jack wanted to sit before drilling. This would have us drill at the edge of the case, but it would be closed off by the phone's back cover anyway so it wouldn't matter. Just plan out your hole instead of eyeballing it.
Unfortunately, we did not get any pictures of the fit after we were done. Probably for the best, so no one has to see the metal carnage.
Once it was in place, it was time to wire it. The speaker module presses a flat flex cable up against these two contacts on the board.
Tumblr media Tumblr media
I originally managed to solder to the flat cable, but then made a mistake and tore the pads, so I ended up soldering directly to those spring pins on the mainboard. I used magnet wire for everything. I just connected both the L and R pins of the jack to this one speaker output because I didn't feel like probing out the top speaker connector and running wire up there just yet. Ideally I would have a switched jack that interrupts the top speaker, but that's for later. I might salvage something from an Apple device, their jacks tend to be compact.
Tumblr media
Hot glued the thing in place, and this is the end result. It works just great with passive headphones. I'll upload a demo video when I get the chance, I've already used my 1 video. I wish I had taken better pictures, but it wasn't very convenient.
The caveats in the beginning apply. It's also way too loud because it's meant to drive a speaker, and it's balanced for that too. I might be able to put a resistor divider on there to reduce the output volume and let a louder signal drown out the interference a bit better?
I have no idea if this is a thing people do, putting audio jacks in their phones. But I would think that replacing the speaker like this would work on a lot of different phones. Maybe worth trying?

With these polls about your first cell phone going around, it reminded me of my account on Mowned. This is my cell phone history, not including the brick car phone that my mom had in 1992+. It was in a box and had a big magnetic antenna you put on the roof of the car.

Antenna Efficiency: Why Magnetic Antennas Excel in Small Spaces
In today's fast-paced technology environment, the need for effective wireless communication technologies is greater than ever. As device sizes reduce and the requirement for compact solutions grows, magnetic antennas have emerged as an excellent choice for achieving high efficiency in small spaces. These antennas, sometimes disregarded in favor of their electric equivalents, have particular benefits that make them ideal for tiny applications.
At the heart of their efficiency is the fundamental principle that governs magnetic antennas. Magnetic antennas, unlike standard electric antennas, use magnetic fields to transmit and receive signals.
This permits them to perform admirably despite their diminutive stature. Magnetic antennas' loop construction, which is frequently built of conductive materials such as copper or aluminum, allows them to resonate efficiently at lower frequencies while being small in size. This is especially useful in contexts where space is limited, such as mobile devices, cars, and smart home technology.
One of the most notable benefits of magnetic antennas in confined places is their ability to reduce interference from other electronic devices. Electromagnetic noise is present in urban surroundings from a variety of sources, including Wi-Fi routers, power lines, and other electronic devices.
Magnetic antennas are less vulnerable to this noise because they use magnetic coupling instead of electric fields. This robustness enables them to transmit clearer signals and retain greater connectivity, making them perfect for applications requiring dependable communication.
Furthermore, magnetic antennas are extremely energy efficient, which is critical for systems operating in small spaces. Their narrow-band design enables them to concentrate energy on certain frequency bands, decreasing power waste. For battery-powered devices, this efficiency translates into longer working lifespans and less recharging, which is especially useful in applications such as remote sensors or IoT devices that require ongoing monitoring without frequent maintenance.
Magnetic antennas' modest size adds to their adaptability in a variety of applications. Their compact footprint allows for easy integration into a variety of goods while maintaining aesthetics and functionality. Magnetic antennas can be effortlessly integrated into designs for smart speakers, wearable devices, and vehicle-mounted communication systems, allowing manufacturers to develop elegant and modern products that fulfill the demands of consumers looking for both performance and flair.
Magnetic antennas are very useful in security applications in small places. Their directed transmission characteristics make it more difficult to intercept signals than standard omnidirectional antennas. This heightened security is especially crucial in applications that handle sensitive data, such as financial transactions or private correspondence.
Organizations can protect their data while maintaining effective communication routes by using magnetic antennas.
As the globe embraces the Internet of Things (IoT) and smart technologies, the need for efficient antennas becomes increasingly critical. Magnetic antennas, with their low size and great efficiency, are suitable for supporting the next generation of connected devices. They support communication in increasingly complicated networks, ensuring that data flows easily between devices regardless of space constraints.
To summarize, magnetic antennas are more than just an option; they represent a paradigm shift in antenna design and application in small spaces. Their capacity to give great performance in challenging urban situations, combined with their energy economy and enhanced security features, make them a vital asset in current communication networks. As technology advances, magnetic antennas will play an important part in determining the future of wireless communication, ensuring that efficiency and dependability stay at the forefront of compact device design.

Pompoms, those colorful, fluffy decorations typically seen on cheerleaders' and dancers' outfits, are now making their way to a new, unexpected place: as fender decorations for cars.
This trend started as a fun way for car owners to personalize their vehicles. Pompoms are an easy and affordable way to add a touch of color and whimsy to a car’s exterior. They can be easily attached to the car's fenders, bumpers or even antenna.
But why are people choosing pompoms specifically for their fenders? It turns out there are a few practical reasons for this choice.
First, fenders are visible parts of a car and are often used to make a statement. By adding pompoms, car owners can showcase their personality and stand out in a sea of cars.
Secondly, pompoms are lightweight and do not cause any damage to the car’s exterior. Unlike other fender decorations such as stickers or magnetic decals, pompoms can be easily attached and removed without leaving any residue or scratches.
Moreover, pompoms have some practical benefits as well. They can be used as a buffer between cars during parking or in crowded areas, protecting the car’s fender from any scratches or bumps.
In addition, pompoms can also serve as a warning sign for other drivers. The bright colors and movement of the pompoms can catch the attention of other drivers, especially in low visibility conditions, reducing the risk of accidents.
But it's not just car owners who are embracing this trend. Some car manufacturers have also started offering pompoms as an option for their vehicles, allowing customers to customize their cars right from the dealership.
Pompoms are also a popular choice for car enthusiasts and fans at sporting events and parades. They add a touch of fun and team spirit to their cars, making them stand out in a crowd.
However, this trend has raised some concerns about safety. Some argue that the fluffiness of the pompoms can pose a distraction for drivers and reduce their visibility. To address these concerns, experts suggest keeping the size and placement of the pompoms in mind, avoiding obstructing the driver's view.
In conclusion, while it may seem like a quirky and unusual trend, the use of pompoms as fender decorations serves both practical and decorative purposes for car owners. So the next time you see a car with fluffy pompoms, don't be surprised - it's just another way for people to express themselves and make their car stand out on the road.

Mobile HAM radio antenna || How to choose one?
Tumblr media
Mobile ham radio antennas play a pivotal role in providing amateur radio operators with the flexibility to communicate while on the move. These antennas come in various types, including magnetic mount, glass mount, and roof mount, each with its own set of advantages and considerations.
**What is a Mobile Ham Radio Antenna?** A mobile ham radio antenna serves as the intermediary device between your radio equipment and the outside world when you’re mobile. It is typically small and designed for installation on vehicles such as cars, trucks, or boats, allowing amateur radio operators to establish communication while on the go.
**Types of Mobile Ham Radio Antennas:** 1. **Magnetic Mount Antennas:** These antennas come with a magnetic base, making them easy to install on any metal surface. They are popular due to their convenience, but their performance can be affected by nearby metal objects.
2. **Glass Mount Antennas:** Designed to be mounted on vehicle windows or windshields using adhesive pads, glass mount antennas offer good performance and are less affected by nearby metal objects. However, they may have limited signal range due to the glass barrier.
3. **Roof Mount Antennas:** For maximum performance and range, roof mount antennas are the top choice. They are permanently installed on the roof of the vehicle, providing excellent signal coverage. These antennas are larger, offer superior gain, and are favored by dedicated ham radio enthusiasts and professionals.
**How to Choose the Right Mobile Ham Radio Antenna:** When selecting a mobile ham radio antenna, consider the following factors:
1. **Type of Vehicle:** The choice of antenna depends on the type of vehicle you’re using. Consider the vehicle’s size and capacity to ensure the antenna provides adequate coverage.
2. **Frequency Range:** Ensure that the antenna covers the ham radio bands you are licensed to operate on. Different regions have varying frequency allocations.
3. **Gain:** Antenna gain determines its ability to concentrate radio energy in a specific direction. Higher gain antennas cover longer distances but have narrower coverage areas.
4. **Size & Portability:** Consider the size and portability of the antenna, with magnetic and glass mount antennas being more compact and easily removable compared to roof mount antennas.
5. **Mounting Options:** Evaluate the available mounting options for your vehicle to ensure compatibility with the chosen antenna.
6. **Build Quality:** Choose an antenna with excellent build quality and durability to withstand harsh weather conditions and frequent use.
7. **SWR & Tuning:** Pay attention to the Standing Wave Ratio (SWR) for efficient power transfer. Some antennas may require tuning for optimal performance.
8. **Compatibility with Radio Equipment:** Ensure that the antenna’s connector is compatible with your radio equipment, as incompatible connectors can result in poor or lost signals.
**How to Install a Mobile Ham Radio Antenna:** Proper installation is crucial for optimal antenna performance. Follow these steps:
1. Mark the installation location on your vehicle’s roof.
2. Attach the antenna using the appropriate method, whether it involves drilling a hole and using a bracket or using adhesive for glass mount antennas or magnetically attaching for magnetic mounts.
3. Ensure all connectors are tightly attached to prevent interference.
**Recommended Mobile Ham Radio Antenna:** One recommended option is the “HYS Amateur Antennas Dual-Band NMO 20 Inch Antenna” along with a bracket and 13 ft RG58 coax cable. This antenna offers VHF and UHF frequencies and can be mounted effectively on a variety of vehicles.
*Conclusion:** Choosing the right mobile ham radio antenna is a critical step in building an efficient and reliable mobile ham radio setup. Consider factors such as frequency range, gain, size, portability, mounting options, build quality, SWR, tuning, and compatibility with your radio equipment. Seek recommendations from fellow ham radio operators and consider customer reviews to make an informed decision. With the right antenna, you can enjoy improved signal strength and enhanced overall performance in your ham radio operations.
