I programmed a $7 ESP32-S3 board to block all computer's web ads - and it took just minutes

Raspberry Pi boards have gotten expensive, so I've been looking for cheaper alternatives. I found one in a tiny ESP32-S3 board.

Why this matters
Why now

The increasing cost and limited availability of popular microcontrollers like Raspberry Pi are driving demand for more affordable and accessible alternatives, leading to innovative solutions using cheaper hardware.

Why it’s important

This demonstrates a growing trend towards decentralized, low-cost computational solutions for everyday problems, challenging established hardware ecosystems and empowering individual users.

What changes

The barriers to entry for deploying personalized ad-blocking solutions are significantly lowered, potentially impacting digital advertising models and the demand for more expensive dedicated hardware.

Winners
  • · ESP32-S3 board manufacturers
  • · DIY tech community
  • · Users seeking ad-free experiences
Losers
  • · Digital advertising platforms
  • · Manufacturers of more expensive hardware (e.g., some Raspberry Pi models)
Second-order effects
Direct

Individual users can easily deploy effective, low-cost ad-blocking devices across their networks.

Second

The proliferation of such devices could force a re-evaluation of ad delivery mechanisms and business models by major tech companies.

Third

This might accelerate a broader shift towards more privacy-centric, user-controlled internet experiences, impacting content monetization strategies globally.
