I built a Bitcoin network monitoring tool using a physical ESP32 (no public APIs)

I wanted to understand the actual state of the Bitcoin network — not prices, not predictions, just whether the network is calm or congested.

Instead of relying on public APIs, I built a small physical setup using an ESP32 module that directly observes the network.

I turned this into a public tool:
BlockPulse Insight — Real-time Bitcoin network analysis

What the tool shows:

• network stability (simple score)

• qualitative transaction fee conditions

• a clear signal: good moment to send a transaction or better to wait

No price forecasting.
No trading signals.
No third-party APIs.

The goal is not to predict the market, but to read the state of the network itself.

I’m curious to hear feedback from builders:

• Does this kind of infra-first approach make sense to you?

• What network signals would you want to see next?
