Nucleus ESP is a cost-effective device for hacking and experimentation, capable of Sub-GHz RF transmission. It is still evolving, with ongoing features and upgrades.
Project Overview
Nucleus ESP is a modified yellow device featuring custom GPIO expansion. The RGB diode has been desoldered to free up GPIO pins, while the audio amplifier and photoresistor have been removed to allow for further modifications.
This project started as my first foray into C programming, after gaining experience with PHP and FPGA experimenting. I’m learning by experimenting and building as I go.
By this project, i already learned everything from what modulation is, to how to make decoder/encoder, to start learning about filtering signal digitally. From virgin to RF hacker? Just don't buy Flipper
I started o write encoders and decoders for common protocols like CAME, and NICE. Which are working, so now, i trying to make the filter of the signal.
After some fails i found performance/skill issue sweet spot in form of BC556 transistors, and finally have IR blaster send to overdrive. I utilize classic form IR led on which i measure around 0.8 A, and "1W 160 degrees" IR led on which i measure around 2A (i cant really measure that precisely since keeping it just power on cause death of small LED or BC556 -> intended, when it started burn, i take step back...) *FW is in kinda mess, i need to clean that ASP.
