5G 12dBi Magnetic Antenna with RG174 Cable

A 5G 12dBi magnetic antenna is a type of antenna designed to enhance the performance of 5G wireless communication devices, such as routers, hotspots, or modems. Let's break down the key features:

5G: 5G is the fifth generation of wireless technology, which offers faster data speeds, lower latency, and greater capacity compared to previous generations (4G, 3G, etc.). The antenna is specifically designed to work with 5G networks and devices.

12dBi Gain: The "12dBi" figure refers to the antenna's gain, which is a measure of how much the antenna can increase the power of the signal it receives or transmits. A higher gain indicates better signal reception and transmission capabilities. In this case, a 12dBi gain suggests that this antenna can significantly boost the signal strength.

Magnetic Antenna: The term "Magnetic Antenna" indicates that the antenna can be attached to metal surfaces using a magnetic base. This feature provides flexibility in terms of placement and allows for easy positioning on metallic surfaces, like the roof of a car or a metal housing for a 5G device.

Magnetic antennas are often used in mobile applications or in scenarios where temporary or flexible mounting is required. This type of antenna is convenient because it can be easily installed and removed, making it suitable for mobile installations or where drilling holes or more permanent mounting solutions are not practical.

Battery-free technology can power electronic devices using ambient radiofrequency signals

Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module—developed by a team led by scientists from the National University of Singapore (NUS)—can now convert ambient or "waste" RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries. RF energy harvesting technologies, such as this, are essential as they reduce battery dependency, extend device lifetimes, minimize environmental impact, and enhance the feasibility of wireless sensor networks and IoT devices in remote areas where frequent battery replacement is impractical. However, RF energy harvesting technologies face challenges due to low ambient RF signal power (typically less than -20 dBm), where current rectifier technology either fails to operate or exhibits a low RF-to-DC conversion efficiency. While improving antenna efficiency and impedance matching can enhance performance, this also increases on-chip size, presenting obstacles to integration and miniaturization.

WOAH HOW DO YOU DO A PIRATE TELEVISION STATION?? THAT'S SO COOL!! (you don't need to share if having that info public would cause the station to be taken down)

It’s pretty simple. You need an RF modulator (I use a rack mounted Blonder-Tongue Agile Modulator), which every VCR also is. You just put some source video into that (I often just use a chromecast + HDMI2AV adapter), and attach an antenna to the RF-out. 

The trick is that it only gets into “the FCC will get mad at you” territory if you’re broadcasting with more than a watt or two of power. Most RF Modulators are limited to that much anyway (because they’re intended for internal cable TV networks) so as long as you don’t stick an amplifier on it, you’re in the clear.  

Here’s a picture of my broadcast rack from a while ago:

I just racked it because I had a couple units (and I’ve gotten more since I took this picture) but you can just use a single modulator on its own without needing a rack.

A mini GPS from uBlox with I2C and UART 🛰️📡🔧

The SAM-M8Q

is an entry-level 'all in one' GPS from uBlox - it comes with both UART and I2C interfaces plus a built-in antenna so it's ready to go 'out of the box.' It's also fairly small, so we decided to try and make a little breakout for it. It exposes both interfaces, but we expect most folks will like using the Stemma QT port for instant I2C interfacing. We gotta dig into uBlox's interface since we expect the I2C to be a little more complex than the PA1010 we've used.

I saw @pc-98s do this and I had to try it for myself, can confirm it's very cool

(I forgot to add context that this is being streamed via an rf modulator through an antenna to the tv)

The girlies all together

Twin Famicom (NES model by Sharp)

The Twin Famicom is a video game console system that was produced by Sharp Corporation in 1986 (Juli 1) and was only released in Japan. It is a licensed Nintendo product that combines the Famicom (NES) and the Famicom Disk System into a single piece of hardware.

The essential parts of the Twin Famicom include a 60-pin socket for Famicom cartridges and a socket for Disk System disk cards. The player could switch between the two media types with a switch – cassette "カセット" or disk "ディスク" The Twin Famicom is fully compatible with the NES and can handle accessories made for the NES (e.g. Beam Gun). But there is also an extra port on the Twin Famicom. This allows a 'regular' Famicom to use the Twin Famicom's disk drive.

The original Famicom only has one color combination, and the Twin Famicom was initially sold in two colors: red with black highlights (AN-500R), and black with red highlights (AN-500B). A second version of the system was released in 1987 with a slightly different case design, turbo controllers, and two different color schemes; black with green highlights (AN-505-BK) and red with beige highlights (AN-505-RD).

Like the Famicom, the Twin Famicom uses NTSC but with an AV output rather than an RF modulator[2][3] with an RCA connector for composite video and mono audio, allowing for greater audiovisual quality on TVs and monitors with such inputs. An external RF modulator is bundled with the unit for connection through a TV's antenna/cable input. The two gamepads are hardwired into the console, so they cannot be disconnected.

The People have spoken,

JermaTV is go. If anyone is interested/has technical questions feel free to ask but I’ll basically be modifying a composite TV RF modulator to be amplified slightly through an LNA board and out into a dummy load/highly non-efficient antenna. (I’ll play with power levels and see what the best output I can get is while following local regulations)

As far as what I’ll actually broadcast, please send me your favourite jerma moments™ and I’ll broadcast it on air / see if I could make a YouTube video out of it if you guys want.

Guide to Using a Spectrum Analyzer for Harmonic Measurement

A spectrum analyzer is an instrument used to measure signal spectra, displaying frequency components and their relative amplitudes, aiding engineers and technicians in understanding signal characteristics. In spectrum analysis, harmonics are crucial. Harmonics are integer multiples of the fundamental frequency signal, typically generated by nonlinear systems. In audio, radio frequency (RF), and power systems, the presence of harmonics can lead to issues like interference and efficiency loss. Understanding and managing these harmonics are vital to ensuring the proper operation of systems. SPA-3P6G_Spectrum Analzer Usage Guide: Measuring and Analyzing Harmonics • Understanding Harmonics Basics: Harmonics are signals with frequencies that are integer multiples of the fundamental frequency. While pure signals ideally lack harmonics, real-world systems with nonlinear components generate them. • Selecting the Right Spectrum Analyzer: Choose a spectrum analyzer that covers the frequency range of the signal of interest and its harmonics. • Preparing the Spectrum Analyzer: Preheat the spectrum analyzer for stability and accuracy. Check calibration status and calibrate if necessary. • Setting Spectrum Analyzer Parameters: Set parameters like center frequency, frequency span, resolution bandwidth (RBW), video bandwidth (VBW), and scan time based on signal characteristics. • Connecting the Signal Source: Use appropriate cables to connect the signal source to the spectrum analyzer’s input port. If using antennas, ensure correct installation and orientation. • Initial Scan: Perform an initial spectrum scan to observe signal distribution across the frequency range and identify the fundamental frequency and harmonic ranges. • Precisely Locate Fundamentals and Harmonics: Adjust center frequency and frequency span to center the fundamental frequency on the display. Use narrower resolution bandwidth for accurate frequency measurements. • Measure Harmonic Amplitudes and Frequencies: Utilize the spectrum analyzer’s marker function to measure harmonic amplitudes and frequencies, ensuring amplitude calibration accuracy. • Analyze Harmonic Spectrum Characteristics: Analyze harmonic frequency, amplitude, bandwidth, and modulation type to identify harmonic sources and generation mechanisms. • Using Tracking Generators: If the spectrum analyzer has a tracking generator, generate signals at the same frequencies for further analysis and harmonic source localization. • Time Domain Analysis: Some spectrum analyzers offer time-domain analysis to observe transient characteristics of harmonic signals. • Advanced Spectrum Analyzer Features: Utilize features like max hold, min hold, and averaging modes to reduce random noise effects for clearer harmonic observation. • Harmonic Source Localization: Based on measurement results, attempt to localize harmonic sources. Move the spectrum analyzer or use directional antennas if necessary. • Harmonic Suppression Measures: Upon identifying harmonic sources, implement corresponding suppression measures such as filtering, cable rearrangement, device setting adjustments, or using harmonic filters. • Documentation: Record measurement processes and results, including harmonic frequencies, amplitudes, possible harmonic sources, and suppression measures taken. • Continuous Monitoring: After addressing harmonic issues, regularly monitor using the spectrum analyzer to ensure harmonics do not reoccur. • Maintenance of Spectrum Analyzer: Regularly maintain and calibrate the spectrum analyzer to preserve its performance and accuracy. • Advanced Analysis: For complex harmonic issues, conduct advanced analyses such as total harmonic distortion (THD) analysis, power spectral density analysis, or modulation spectrum analysis. Precautions： • Ensure input signal levels do not overload to avoid measurement errors. • Consider the modulation characteristics of signals, as modulation may affect harmonic measurements and analysis. • Use specific measurement accessories (such as harmonic mixers or harmonic filters) for particular harmonic measurement tasks. • Be mindful of DC components in signals, as they may affect measurement results. • Consider environmental factors (such as temperature, humidity, and electromagnetic interference) that may influence measurement results. • By following these steps and precautions, the spectrum analyzer can be a powerful tool for measuring and analyzing harmonics, assisting engineers in enhancing system performance and reliability.
