How I Made This Transparent Hollow Clock - It is 3D Printed! 

Try printing a phone case

@@DELTA_SKULL Yeah, I need a proper filament for that, please stay tuned, InshaAllah, I will do it:)

@@engineericly ok by the way love your videos

@@DELTA_SKULL Thank you :)

It would probably look more realistic if the arrows of a clock were triangles with a base of a triangle being in the center and a thin tip of a triangle connecting with the outer gear Great videos, by the way! :)

You can even use 12v for the stepper motor controller

YES and if you want to do it a bit beter you can take the 5v from the voltage regulator on the Board, then you still have your usb functional.

And the node MCU has a pin called "vin" or "raw" where it breaks out the USB power

or use a voltage regulator to step down from the 5v, a single chip

Thanks for your cool ideas

Thank you so much!😊

Thank you dear!

Idea is not mine but, Thank you so much!!

thank you:)

looking for it too

thank you!

Hello, No NodeMCU boards do not have 5V pins by default, they provide 3V so you need to step it up or provide other external power supply for the driver

@@engineericly to nodemcu your connecting usb ryt, which power your nodemcu. Usb provide 5v to nodemcu which will be given to ams1117 to reduce to 3.3v to power esp8266 12. In some case you need run nodemcu with external 5v supply, so the usb 5v is connected to vin pin (name of the pin differ in different manufacturer), so if you connect USB power and check the voltage between vin and gnd u will get 5v you can use it run any 5v device....

thank you :)

Thank you so much 😊

:)

thank you man!

Thank you :)

Yes, Now, planning to make more long useful videos about interesting projects, thank you for your support!

I have the same issue. If you resolve it then please help me how you did it.

Wow, thank you for your feedback, will try to improve more😊

thank you :)

Will try InshaAllah, thanks for the comment 🙃

Thank you 😊

Spasibo brat!

Yes, but Arduino nano has some problems with RTC module, if want to use Arduino nano you have to add external RTC module, then it is fine

@@engineericly why use any microcontroller at all?

Va alaykum Assalam, thank you brother :)

Thank you for your feedback, I will consider tis advice!

The version for ESP8266 already obtains its time from internet (to see in the video when the log of the firmware start is shown). There is no possibility to recognise the position of the flying hour hand without destroing this special effect of unconnected hand.

@@snowhead8822 you can use magnets or wider zones, or some electric material to find start of each circle

@@aliday9968 Nope. Take a look at the mount of the hour hand, please. There is no ring for it. It hangs with its gear free on the virtual axle of the minute hand. Only the outer gear wheel of the minute hand can be accessed for position detection.

@@snowhead8822 interesting but it can sync the time every 12 hours with some sensor(photo sensor, microswitch, etc…) at that position of the cog right? If at that time the sensor is not triggered power the servo until it is. Just thinking out loud.

@@myounges Like told before it's no problem to obtain the position of the minute hand. But with the unknown position of the hour hand an automatic synchronisation is not possible. The only possibility I can imagine at the moment is a hollow minute hand coated with black color inside. It's tube has one hole through the gear ring and one hole on its back side in the hight of the hour hands tip. Inside the minute hand before the inner hole to the hour hand there is an tilted mirror placed. In the base on the position of the minutes hand at 06:33 hour is placed a laser diode firing through the minute hand over the mirror out of the hole on the back. Close near this diode a phototetector receives the reflected light. Normally the gear ring reflects the most of the light back to the detector. This causes a high signal. Every hour on the 33. minute the minute hand with it's hole let the beam pass and so on all hours except 06:33 hour there is nearly no reflected light causing a signal near zero. At 06:33 hour the hour hand is positioned direct behind the minutes hands hole reflecting a part of the beam back through the hole over the mirror to the detector. Because only a small part of the light reaches the detector the caused signal should be only a bit higher than at all other hours. So the controller knows, that the hands are in the position of 06:33 hour and can now synchronize with the current time. The main chellanges are the making and positioning of the tiny tiny tilted mirror and to place laser diode and detector as close as possible to each other because both must use the same small tube through the minutes hand. I'm not sure if the light reflected by the hour hand can be reliable detected.

Thank you for your feedback. Actually it has been long since I bought that! But I think it came with my drill set.

Just wondered what sort of shape the drill bit was

@@jean-michelchevalier6649 It looked like just a straight, diamond grit grinding bit. But I don't think it's that important. A round needle file should work just as well.

Thank you!

Rahmat!

Thank you :)

Congrats brother! 😊
