🎡 Throwback: GBC 38 – Funky Ferris Wheel 🎡
Some GBC modules never lose their charm.
GBC 38 Funky Ferris Wheel is one of those builds — a classic PV Productions GBC from a few years ago that still delivers smooth motion and eye-catching mechanics.
Built entirely from LEGO® Technic set 42098 (Car Transporter), this module features a large rotating Ferris wheel with 12 carriages that continuously lift and release GBC balls in a steady, rhythmic flow.
⚙️ Why it’s still special
• A big, smooth Ferris wheel that dominates any GBC layout
• Automatic ball loading with reliable timing
• Continuous loop: balls always return to the wheel
• Hand-crank powered, with an easy option to motorize
• Optional extras like Xylophone Keys, or Funnel elements
With a footprint of 80 × 70 cm and a height of 25 cm, GBC 38 works perfectly as a standalone module or as part of a larger Great Ball Contraption setup.
If you’ve built it back in the day — or you’re discovering it again now — GBC 38 remains a fun and satisfying build that still holds up today.
