Custom RGB 14-Segment Display Built from Scratch Custom RGB 14-Segment Display Built from Scratch

YouTuber EastMakes set out to build something, a true RGB 14-segment display module. Wanting a retro alphanumeric display style for a large LED message board project, he designed his own module using ultra-tiny SK6805 addressable LEDs measuring just 1.5 mm square. Since datasheets lacked precise placement references, he scanned a physical display and calibrated the image in CAD software to…

LiteWing Flight Positioning Module NeoPixel Status Control (WS2812B) LiteWing Flight Positioning Module NeoPixel Status Control (WS2812B)

In this guide, we focus on the WS2812B addressable RGB LEDs on the LiteWing Flight Positioning Module. The module includes four NeoPixel-compatible LEDs, each independently controllable via software. These LEDs are useful for flight status indication and visual debugging during development. A curated collection of hands-on drone projects with guides showing how to…

Driving NeoPixel LEDs Using Pure Hardware Driving NeoPixel LEDs Using Pure Hardware - No Microcontroller, No Code

A recent video by Axiometa explores an unusual electronics challenge: driving addressable NeoPixel LEDs entirely in hardware, without any microcontroller or code. Since WS2812-style LEDs normally rely on tightly timed digital data from MCUs, the project asks whether basic components like counters, timers, and logic gates can replicate the protocol. The goal was to generate the required pulse…

DIY Macro pad with six buttons, an OLED display, and a rotary knob with RGB lighting A Smart Macro Pad with Haptic Feedback

Ever thought of controlling your computer using buttons and a knob that actually feel different when you use them? Most input devices, like keyboards and mice, only give visual feedback on the screen and do not provide any physical sensation to indicate how an action feels. The Macropad changes this experience by adding the sense of touch to everyday computer controls. This is a six-button…
