$1,000/month from hardware maker contributions (explicitly stated). Additional $7,000 net profit from a batch of 300 self-manufactured OG Xbox adapters. One Chinese company has been sponsoring via GitHub Sponsors since August 2022.

Marketing Channels

Primary

Open source community

The open-source firmware attracts hardware makers who build products on top of it and make voluntary financial contributions

Ongoing

GitHub Sponsors

A Chinese AliExpress company has been sponsoring the project since August 2022, apparently on autopilot

Secondary

Hacker News

Creator has shared updates in HN threads multiple times over the years, building community awareness

Planned

Direct hardware sales

Creator manufactured and sold 300 OG Xbox adapters via blueretro.com, planning a second batch

Growth Levers

  • Scale direct hardware sales by outsourcing assembly to reduce the 48-hour manual labor bottleneck
  • Formalize licensing or contribution tiers for commercial hardware makers using the firmware
  • Expand product line beyond OG Xbox to other popular retro consoles
  • Reach out to more AliExpress sellers who use the firmware but do not currently contribute
  • Create video content demonstrating the adapter with various retro consoles to tap into the retro gaming YouTube community

First Customer Strategy

The project started as a hobby and gained traction through the open-source retro gaming community. Hardware makers adopted the firmware for their own products and began making voluntary contributions. Chinese companies on AliExpress also adopted the firmware, with one becoming a recurring GitHub sponsor.

Pricing Insight

Revenue model is multi-layered: voluntary contributions from hardware makers (~$1K/month), GitHub sponsorships from commercial users, and direct hardware sales ($7K net on 300 units). The creator acknowledges the manual assembly economics are not great (48 hours of labor for $7K) but expects the second batch to yield double due to reduced fixed costs.

New Market Opportunities

  • Pre-assembled retro gaming adapters Commenter asked about sourcing and assembly, indicating interest in the hardware manufacturing process and potentially the end product
  • Second batch with improved economics Creator plans a second batch that should yield $14K net since only raw materials and shipping costs apply

Key Takeaways

  • • Open-source projects can generate meaningful revenue through voluntary contributions from commercial users of the code
  • • Recurring sponsorships from commercial users can become reliable passive income — especially when the sponsor forgets to cancel
  • • Manufacturing your own hardware provides a valuable learning experience but may not be economically optimal without outsourcing assembly
  • • First-batch manufacturing has high fixed costs, but subsequent batches benefit from amortized tooling and only incur marginal costs
  • • A 5-year track record in a niche community builds deep trust and enables multiple monetization paths (sponsorship, contributions, direct sales)
