I dare say that using the level tube on the clock is a pioneering work, because no one has tried it, and no one has such an idea. The owner is the first to try to do this. Compared with the use of modern devices such as LEDs on VFD clocks, it is quite unmatched. However, the principle of the level tube is the same as that of the VFD. It is also a glass tube, so it is quite consistent in terms of principle, shape and structure or other aspects. Sex only illuminates two segments to make up the clock: the symbol, compared to LEDs or none at all, do you think this is a good idea, like a finishing touch, instantly has what a clock should look like.
About:
Standardversion is a simple 4-bit clock
. Level tubes cannot be installed. The circuit board does not support, and there is no place for installing level tubes on the decorative board.
Upgraded versioncircuit board supports the installation of level tubes, and the installation position is reserved on the decorative board.
The finished product is as shown in the picture. It can be used after plugging in. It includes IV11, circuit board and level tube.
Using DS3231 real-time clock (RTC) chip, the time will continue to run after the power is off, and the time will not be lost
The single-chip microcomputer uses STC15 single-chip microcomputer
With manual stepless brightness adjustment function
Use more complex static display circuit, display no flicker and high brightness
This product only has the function of displaying the time. It is a 24-hour system and cannot be changed. There is no RGB, alarm clock and other various messy functions.
The power interface is the MICRO USB power supply voltage; 5V power consumption depends on the brightness. High brightness power consumption rises (up to a few watts), low brightness power consumption drops (a few tenths of a watt)
The power cable (data cable) and the charging head (power adapter) need to be prepared by the buyer. Use the unused Android phone charger and data cable.
At the highest brightness, the power consumption is relatively large. It is recommended to use a charger with 1.5A or above and a middle brightness of 1A.
It is normal for this product to heat up during work
Four digits are displayed as hour, hour: minute, minute, hour and minute, no second.
