EDC FB1 IEZEN

Most fidget toys stop at mechanical motion. The EDC FB1 IEZEN adds a screen to the equation: according to the maker, a metal slider is integrated with a 150-pixel RGB LED matrix so that each movement of the finger triggers a visual response. The pocketable body also packs gyro sensing, haptic feedback and 11 play modes.

Slider meets sensor

The maker describes a slim metal body with 22.3 mm of slide travel, sized to sit comfortably in a pocket. A mechanical curve said to be inspired by the golden ratio is meant to keep the feel consistent across the full stroke. Inside, five Hall sensors track the slider's position in real time, turning the mechanical motion into electronic input that drives the LEDs and vibration.

Two materials are offered, per the source: an aluminum alloy version positioned as the lighter everyday option, and a titanium alloy version described as having a heavier, more premium feel.

A 5×30 light display

The front-mounted matrix uses a 5×30 layout of 150 RGB pixels. The maker says its resolution supports flowing animations, a flickering candle effect, rainbow patterns and an hourglass-style display. Because only the light changes, the company pitches it as discreet enough for meetings, and as a soft ambient light in a dark room.

11 modes

• Flow: light moves like a digital liquid, launched with a left slide and touch
• Candle: a flickering flame pattern
• Warning light: a strong visual response to each slide
• Rainbow: continuously shifting colors
• Hourglass: pixels move to represent passing time
• Dice: random results on each slide
• Decision: shows a random answer for small choices
• Mokugyo (wooden fish): a meditative rhythm from repeated taps
• Slider: LEDs follow the mechanical slide
• Push counter: displays a count of slides
• Vibration: haptic feedback delivered to the palm when sliding

The maker also notes that gyro sensor and Bluetooth hardware are built in, allowing the device to react to tilting and rotation, which the source frames as potential for broader interaction beyond sliding.
