If you’re into crypto, DIY gadgets, or just like having blinking little devices on your desk, you’ve probably heard of the Nerdminer. I’ve been playing around with these hobby miners myself, and let me tell you — they’re terrible for making money, but amazing for tinkering.
Here’s my personal take on Nerdminer setups, how they work, and why I keep going back for more… even knowing the odds are laughably low.
What Is a Nerdminer?
A Nerdminer is basically a tiny Bitcoin mining device that runs quietly on your desk. Most hobbyists, myself included, use ESP32 microcontrollers or small ASICs to experiment with Bitcoin mining.
I use mine for hands-on learning, seeing hash rates tick up, and just feeling like a crypto wizard while sipping coffee. You don’t need a warehouse to participate — just a little desk space and some curiosity.
How Nerdminers Work (Warning: Odds Are Terrible)
Nerdminers mostly do lottery mining. Here’s the deal:
-
Your device connects to a mining pool.
-
Every ~10 minutes, there’s a tiny chance your miner or pool finds a valid Bitcoin block.
-
Most of the time, nothing happens. Your Nerdminer just blinks at you like it’s shrugging.
Honestly, the odds of earning a full block are about the same as winning the lottery while being struck by lightning. But that’s kind of the point — it’s about tinkering, not retiring.
Nerdminer rule #1: Don’t expect to get rich. Expect to tinker, learn, and feel nerdy as hell.
My Personal Nerdminer Setup
Here’s what I actually use on my desk to experiment with crypto mining:
Hardware / Models I Use:
-
LILYGO® T-Display-S3 ESP32-S3 1.9 inch ST7789 LCD Display Development Board – Wifi + Bluetooth 5.0, 170×320 resolution.
-
LILYGO T-Dongle-S3 ESP32-S3 TTGO Development Board – 0.96” ST7735 LCD display, TF card.
-
ESP32-2432S028R ESP32 2.8″ Display Resistive Touchscreen TFT LCD Module – 240×320, perfect for tinkering.
Pool I Use:
-
web.public-pool.io — simple, open pool that lets my devices contribute without fuss.
Firmware:
-
I run the open source Nerdminer V2 — it’s super flexible and great for experimenting with firmware tweaks and learning how mining actually works.
Why I Keep Nerdminers on My Desk
Even knowing I’ll probably never mine a full Bitcoin, I love these devices for:
-
Learning by doing: Watching hash rates, tweaking firmware, and understanding pools firsthand.
-
Tinkering factor: Screens, LEDs, Wi-Fi setups, small firmware hacks — endless fun.
-
Conversation starter: People see blinking screens and ask, “What’s that doing?” Instant nerd cred.
-
Desktop satisfaction: There’s something oddly soothing about tiny devices working silently on your desk.
Honestly, the Nerdminer experience is more like a fun puzzle than a profit machine.

Still not a get-rich-quick scheme — but more fun and more chances to see those numbers tick up!
Final Thoughts
Nerdminers aren’t about making a fortune. They’re about hands-on learning, tinkering, and geeky satisfaction. Watching my little ESP32 boards blink and hash, learning firmware tweaks, and experimenting with pool settings is just as rewarding as seeing a large ASIC churn coins in a warehouse… maybe even more satisfying, because it’s my desk.
If you want to tinker, learn, and laugh at the odds, grab a Nerdminer (or a BitAxe/NerdQAxe if you want more juice) and join the hobbyist crypto scene.
✅ Pro Tip: Track stats, tweak firmware, play with the pool, and most importantly — enjoy the tinkering process. Nerdminer = education + fun + nerd cred.
