From the project

DIY giant 7‑segment display made from green COB LED strips on perfboard (145×65 mm digit, 5 V, 90 mA per segment).

This project describes a simple DIY giant 7‑segment display built from low‑cost LED strips and perfboard. The goal is to get a large, clearly visible digit with minimal components and manufacturing effort.

- Supply voltage: 5 V - Segment current: 90 mA (green COB LED strip) - Digit size: 145 × 65 mm (overall dimensions of one segment digit)

- Each segment is a piece of green COB LED strip, 50 × 8 mm in size, mounted on double‑sided adhesive tape. - The COB (Chip‑on‑Board) technology places many LED chips very close together and encapsulates them in a single layer of compound, producing a…
