Electronic hourglass

This is an electronic hourglass using two 8x8 dot matrix LEDs.
This is an assembled unit from a kit that was previously sold.

It has a built-in accelerometer, and the LED lights move when the unit is turned sideways or upside down.
It also functions as a 1-minute, 3-minute, or 5-minute timer by shaking it vigorously up and down.
The height is 12.2 cm.

Requires 4 AAA batteries, which must be purchased separately.
To access the battery compartment, open the lid without the red switch using the included screwdriver.

The case is made with a 3D printer.
The material is PLA.

If you are confident in your abilities, you can also run your own custom programs by downloading the program from the URL at the end of the instruction manual.
Since DuPont cables are used for wiring, wiring changes can be made without soldering.
The photo of the interior is of a prototype, so the wire colors may differ.
Modifications are at your own risk.

Please Note:
- Due to production using a home-use FDM 3D printer, there are visible layer lines.
- PLA deforms at temperatures above 60°C, so please avoid placing it in high-temperature areas.
- We do not accept price reductions.
