rcfw Arduino Nano shield
Jun 04,2026
This is a companion shield to my rcfw firmware (see link).It can take one Arduino Nano or Every (or a compatible clone), two ESCs, one servo, one ELRS receiver (with optional power control via Arduino), two sets of two LEDs (via transistor) and I2C. Power from the second ESC is broken out to a header, allowing supplying power to three other devices. To use this as a second servo manually solder a bridge to VCC of the other ESC.Models this has been tested with include RC Benchy, Arctic Tinyrider ...

Simple SDR Receiver Using 2x NE612 - Dual Conversion, Superheterodyne (0.1–30 MHz)
Pavleski Jun 03,2026
 SDR (Software Defined Radio) is a radio system in which most of the functions of a classic radio (filtering, demodulation, tuning, AGC) are performed by software instead of hardware. The hardware serves mainly as a receiver and signal converter, and then the computer processes the signal. The main advantage is flexibility: with the same device you can listen to AM, SSB, FM, DRM and other signals just by changing the software. The disadvantage is that it requires digital processing and ofte...

Talking Tom
Jun 01,2026
Talking Tom: Bare-Metal Voice Modulator & Raw SPI Flash Streamer1. Project OverviewThis project is a high-performance, real-time embedded digital signal processing (DSP) device named "Talking Tom". Built entirely on the 8-bit ATmega328P (Arduino Nano) platform, the system captures live human voice through an electret condenser microphone, saves the raw audio bytes directly into sector addresses on an SD card, and plays the recording back through a power amplifier with a hardware-driven chipm...

solenoid_controller
bliz May 29,2026
this is a small device used to control a solenoid. we made it as part of a research projec t to study the electrical response of piezoelectric crystals when a specific force is applied.we first calibrated the solenoid (find the froce it produces for a given pwm) using a 20kg load cell and HX711 module.then we used this data to produce a function that could convert the speciied force to required pwm. thus the solenoid can apply the force specified. the final device has a 1602 lcd and a 4x4 keypad...

DIY Vintage TV VU Meter with peak indicators
Pavleski May 28,2026
 Some time ago in one of my projects I presented you a way to turn a black and white old mini TV into a Retro Clock. This time I will describe another project with which you can use your old TV and turn it into a beautiful video effect, and that is a full screen Stereo VU meter. Again I will use the Arduino Nano microcontroller and the appropriate library for generating a composite signal. Most often, old TVs do not have a composite input, so we need to modify it in the way descri...

DIY Tesla Coil based Plasma Rife Machine
Pavleski May 21,2026
 In several of my previous videos, I presented you with different ways to make a Rife Machine, from the simplest with metal electrodes as a medium for the transfer of frequencies, to an advanced Plasma Rife Machine. This time I will stick to the more advanced versions which, like the original device, use plasma as a medium that radiates into the environment. With the previous devices, I mostly used a configuration that consisted of: a carrier signal generator, a modulator, an amplifier...
