28.8MHz RTL-SDR TCXO
Details from 28.8MHz RTL-SDR TCXO
The standard RTL-SDRs (and especially ones in a smaller case) drift quite a lot in frequency until they have warmed up. This makes receiving narrow band signals (in the HF bands, using an upconverter) quite hard without periodically readjusting the tune...

Tiny Low-Tech tracking transmitter
Details from Tiny Low-Tech tracking transmitter
This is a little circuit that could be used to track an object up to 400m. It is a SAW stabilized OOK modulated RF transmitter, the modulation is done with two low frequency ultra low power oscillators that activate the transmitter every two seconds...

Raspberry Pi OP25
Details from Raspberry Pi OP25
This is a better version of a Raspberry Pi Police Radio as we are using OP25 alone, in lieu of DSD paired with GQRX. The DSD/GQRX combo was initally chosen because of its visual impression, however OP25 works much better, it doesnt suffer from having...

How to hack a car
Details from How to hack a car
Just to be clear, no, just by reading this you won't be able to go around unlocking car doors. I worked on this project because I was interested in learning the basics of radio and how data is modulated... also I want to be able to tell people I hacked...

ESP433: WiFi to 433MHz bridge
Details from ESP433: WiFi to 433MHz bridge
If you already know about simple ASK/OOK 433MHz devices, you probably know they're pretty easy to interact with via software defined radio. It felt like a shame to tie up a whole SDR module just to control some lights, so I wanted to design some...

Details from Raspbian and other Raspberry Pi Software
Raspbian is the main and basic software for RPi devices, officially supported by the Raspberry Pi Foundation. In fact, it is an operating system, based on Debian and optimized for Raspberry Pi hardware. It comes with lots of pre-installed pieces...

Cyberdeck for 2024 Challenge
Details from Cyberdeck for 2024 Challenge
When my station isn't in a radio silence and doing really Recon passively and connect my wire or buy 5G or Wi-Fi it will have access to my personally trained large language model, convolutional neural network, with several additional modules and an agent...

AM Band Voice Frequency Marker
Details from AM Band Voice Frequency Marker
The idea is simple: generate an entire broadcast band of stations at once. The first prototype (software-only) makes each station announce its own frequency in a synthesized voice. This is convenient for aligning and testing antique or simple radios,...

Luggage
Details from Luggage
The case is a Peli 1300 "Protector" which I got second-hand from eBay. First task, cleaning off the original industrial labels (paint scraper + solvent) and then replacing the damaged handle and clips. (Part of the RS components order, along with the...

Hello, World
Details from Hello, World
Most of the CPLD or FPGAs having both Configuration Flash Memory (CFM) and User Flash Memory (UFM). This simple and fun project explains how we can utilize the UFM and adding a simple binary counter can be used to display messages using POV. This...
