ROMini SMPS Test: MOSFET-Driven Flyback Transformer
Quick experiment: testing a small switching power-supply transformer driven with a MOSFET and a 3.7V Li-ion battery.
Flyback-style setup with freewheeling diode and gate resistor.
In the video I show the primary drive behavior and the response on the secondary.

THThat capability led me to explore the defensive implications of signal injection and spoofing. Using an ESP8266 running custom firmware, I began generating multiple synthetic Remote ID-like broadcast sources to observe how they appear within Colonel Panic's Python-based visualization pipeline.
The results are instructive. When viewed through the same detection and mapping tools, these injected signals are indistinguishable from legitimate Remote ID emitters without additional validation layers. From a real-world perspective, this highlights both the strengths and limitations of passive drone detection systems.
On the defensive side, this type of research has clear applications: understanding how detection systems can be saturated, misled, or stressed helps improve their resilience. In contested or high-risk environments, distinguishing genuine aerial assets from decoys becomes critical-and studying spoofed telemetry is one way to identify where current assumptions break down.
This work is focused on analysis, simulation, and system hardening, not disruption. The goal is to better understand how modern drone identification ecosystems behave under non-ideal conditions, and how they can be improved.

PLSoft start of a high rpm fan (12V) recovered from a discarded power supply of an old server.
When the button is pressed, first the buzzer alerts with four beeps and the the fan starts to spin slowly and increasing the speed until the max (PWM), keeps spinning ten seconds and stops.

GEDiode: A diode is a semiconductor device that allows current to flow one way, blocking it the other. It's like an electronic check valve.
Rectifier: A rectifier converts AC (alternating current) to DC (direct current) using diodes. Common types include half-wave and full-wave rectifiers. Used in power supplies. 💡

Flyback Diode कैसे काम करता है?
✔ Normally diode reverse biased रहता है (current flow नहीं करता)
✔ जब coil ON होती है – diode inactive रहता है
✔ जैसे ही coil OFF होती है – high voltage generate होता है
✔ उस time diode conduct करता है और current को loop में circulate कर देता है

HAIn this video I test the LD1020, a low-cost 10 GHz Doppler radar motion sensor that can detect movement through wood, plastic, and even glass. Unlike traditional PIR infrared sensors, this radar module works by sending out a microwave signal and detecting the Doppler shift when something moves. I’ll show you how it works, explain the pinout and timing behavior, and demonstrate its real-world range and sensitivity. For less than two dollars, it’s an impressive sensor for DIY electronics, alarms, and smart projects.

REFull-wave rectifiers are commonly used in power supplies to convert AC to DC, providing the steady DC voltage needed for electronic devices. There are two main types of full-wave rectifiers: Center-Tapped Full-Wave Rectifier and Bridge Rectifier.
A Bridge Rectifier uses four diodes in a bridge configuration to convert both the positive and negative halves of the AC input into DC.
▶️ During the positive half-cycle of the AC waveform, diodes D1 and D2 are forward-biased, allowing current to flow through the load in the direction indicated. Diodes D3 and D4 are reverse-biased during this half-cycle and do not conduct.
▶️ During the negative half-cycle of the AC waveform, diodes D3 and D4 become forward-biased, allowing current to flow through the load in the same direction as during the positive half-cycle. Diodes D1 and D2 are reverse-biased in this cycle, preventing current from flowing through them.
This consistent direction of current through the load results in a continuous DC output, as seen in the rectified waveform.
In practical applications, a smoothing capacitor is often added to the output of the rectifier to smooth out the ripples in the DC output, providing a more steady and smooth DC voltage. However, this capacitor is not shown here, as the focus is on the basic operation of the bridge rectifier itself.
