A 7-foot-tall 7-segment display
Seven-segment displays are normally diminutive items, able to show info from a clock or other device, in a size that’s easily tucked away when not needed. Jegatheesan Soundarapandian’s single-digit display, however, is just the opposite standing at nearly seven feet tall.
The project is constructed out of cardboard, with a PVC spine for extra strength. Inside, addressable LED lighting illuminates each segment under Arduino control, with an HC-05 module used to interface with an Android app. Two 18550 batteries provide power for the unit, along with a DC-DC voltage regulator to supply the strip with 5V.
