EEtree
EETree (电子森林, "Electronic Forest") is a Suzhou-based hardware education platform offering FPGA learning kits, circuit-simulation tools, and video curricula. Founded in 2019, EETree Information Technology Limited positions itself as a premier talent-development institution for China's electronics industry.
The company entered Western maker discourse on April 14, 2026, when its US holding entity EETree LLC acquired Tindie — the indie hardware marketplace founded in 2012 and previously owned by Supplyframe and Siemens — triggering a two-week platform outage and a wave of community scrutiny about ownership transparency.
Think of it as the O'Reilly Media of Chinese electronics, now owning the marketplace that makers used to sell their projects.

Why is it emerging now?
On April 14, 2026, Siemens/Supplyframe sold the maker hardware marketplace Tindie to EETree LLC — a Washington State entity linked to Suzhou-based EETree Information Technology. A two-week site blackout, opaque communication, and community questions about the registered address put the company under immediate scrutiny.
Outlook
6-month signal projection and commercial timeline.
Tindie revival hinges on EETree's execution; maker community skepticism is high but the platform has loyal sellers.
Risk · Continued opacity about ownership or another extended outage would accelerate seller migration to Lectronz.

Ideas for term “EEtree”
Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
High search intent from displaced sellers. Comparison of fees, community trust, and feature sets captures evergreen decision-making traffic.
Zero English SEO coverage on eetree.cn. A well-sourced explainer fills a complete SERP gap for weeks.
Ownership timeline is hard to find in one place. Aggregating Tindie's full acquisition chain earns inbound links from maker media.
EETree sells FPGA kits only in China; a bilingual storefront could capture the global demand their acquisition signals.
Hundreds of sellers publicly stated they want out. A low-code migration wizard has direct, immediate demand from the HN thread audience.
First-person hardware seller account. High engagement window is 72 hours around the Tindie announcement cycle.
On April 14, a Suzhou hardware education startup became the steward of Tindie — and almost nobody saw it coming until the site went dark for two weeks.
Paying to acquire a struggling niche marketplace is irrational — unless you're a hardware education company trying to build a Western distribution channel for $30 FPGA kits.
Two weeks of darkness, a registered address that aerial photos show is an empty lot, and a Chinese parent company nobody had heard of — this is Tindie's new reality.
