Brain board, comment storm
ESP-EEG is an affordable 8-channel biosensing board
A cheap mind-reading gadget drops, and the comments instantly get spicy
TLDR: ESP-EEG is a cheaper board for reading brain and body signals, and that alone got people excited because similar gear usually costs much more. But the real show was in the comments: one camp praised the pricing, another questioned the real-world use, and one rival casually showed up to promote a competing board.
A new brain-signal board called ESP-EEG just showed up promising 8 channels for way less money than the better-known OpenBCI Cyton, and the community reaction is basically: wait... is this actually a big deal? The board comes from a former SpaceX hardware engineer, uses a respected sensing chip, and aims to make hobby-grade brain, muscle, and heart-signal experiments more affordable. For curious tinkerers, that’s the dream. For the comments section, that’s an invitation to argue.
The loudest reaction was about price. One commenter practically applauded through gritted teeth, saying the creators had priced it so perfectly they "hate them for it" because the core chip already costs so much that there’s barely any room to go cheaper. In other words: the board may actually be a bargain, and that realization hurt some feelings. Another wave of comments came from the classic internet crowd asking the most relatable question of all: what do you even do with a DIY EEG? That gave the whole thread a fun "cool gadget, now convince me" energy.
Then the side drama arrived. One person politely filed a GitHub issue over broken links like the internet’s least dramatic hall monitor, while another jumped in with a shamelessly juicy competitor plug: they’re launching a similar board with supposedly 5x lower noise. So yes, this wasn’t just a product launch — it briefly turned into a nerdy price war, a credibility check, and a flex-off in public. Even the article’s warning that some promo copy sounded suspiciously AI-generated added a little extra flavor to the chaos.
Key Points
- •Cerelog’s ESP-EEG is introduced as a new 8-channel biosensing board for EEG, EMG, and ECG use at a hobbyist-friendly price.
- •The board uses the Texas Instruments ADS1299 24-bit, 8-channel analog-to-digital converter, the same chip used in the OpenBCI Cyton.
- •The article says Cerelog’s main differentiator is cleaner signal quality through true closed-loop active bias while costing less than the current OpenBCI Cyton.
- •Software support includes a fork of the OpenBCI GUI via Lab Streaming Layer and BrainFlow.
- •Current firmware does not yet enable Bluetooth or Wi-Fi, so the board currently operates only over USB and is not electrically isolated.
