Marketing Channels

Primary

University outreach

Two universities want to buy the Logic Trainer for their programs, indicating institutional sales traction

Secondary

Community feedback (EEVBlog, colleagues)

Received feedback from universities, EEVBlog community, and colleagues that shaped the product from initial concept to advanced Logic Trainer

Ongoing

HN and maker communities

Sharing the project on HN to reach engineers, educators, and parents interested in STEM education

Growth Levers

  • Target university purchasing departments with bulk pricing and curriculum integration packages
  • List on educational supply marketplaces and STEM toy retailers (Amazon, educational distributors)
  • Create companion online content (videos, lesson plans) that teachers can use alongside the hardware
  • Optimize BOM costs to improve margins and enable competitive pricing for the education market
  • Market to the homeschool community where parents actively seek hands-on STEM learning tools
  • Showcase on electronics and maker YouTube channels (EEVBlog, Ben Eater, etc.) for authentic reviews

First Customer Strategy

The creator initially built a simple logic gates PCB to teach a younger brother, then iterated based on feedback from universities, the EEVBlog community, and colleagues. This feedback-driven development evolved the product from a personal teaching tool into a full 'Logic Trainer' that attracted institutional interest from 2 universities and unexpected demand from parents buying for their kids.

Pricing Insight

Not yet profitable due to high development costs. The creator is focused on BOM optimization as one of their learning goals, suggesting hardware cost reduction is a priority to reach profitability.

New Market Opportunities

  • Homeschool STEM education Homeschooling parents are actively seeking hands-on learning tools; the unexpected kid-friendly nature of the product is a market signal
  • Corporate training for hardware companies Hardware companies onboarding junior engineers could use the Logic Trainer as a hands-on introduction to digital logic
  • STEM gift market Positioning as a premium STEM gift for holidays and birthdays could tap into the educational toy market

Key Takeaways

  • • Products built for one person (a sibling) can evolve into commercially viable products when iterated based on broader community feedback
  • • Hardware products have high upfront development costs that delay profitability but can create defensible moats
  • • Unexpected market segments (parents buying for kids) can emerge organically and signal untapped demand
  • • Institutional sales (universities) provide validation and potentially high-volume, recurring orders
  • • The creator's willingness to use the project as a multi-skill learning vehicle (web design, marketing, BOM optimization) maximizes personal ROI even before profitability
  • • Community feedback loops (EEVBlog, universities, colleagues) are critical for hardware product development
