Small Propeller Clock in protective transparent case

[Oskartio15]

can i have hologram clock?

[ciaciacco88]

I'm trying to build one, could you send me the updated firmware? The linked page is in Hungarian...

VERY VERY VERY VERY VERY THE BEST I from Rassia

[sbarry92]

How do you apply power to the PCB board that spins? lol obv you arent using wires? lol

[UtdMan4eva]

I'll crap my self right now if i don't get this thing....you guy's smell something ??

[mraiwa1000]

Can I buy it from you? PIZ!

[TheJunky228]

You could set it on your desk and use it as a multi-functional fan!

OIE SABES DONDE PUEDO COMPRAR UNO EN MEXICO, YO VIVO EN PACHUCA

[whatthafuckisthis]

I'm trowing money to the screen and nothing happens

[Traceurfreerunner]

nice!!!!i want this clock!!!!

[MrHighByte]

AMAZING

[gastonmarak]

CAN YOU SELL ME THIS?! I NEED IT !

Why is there such a large circuit other than the propeller itself? Did you manage to put the controller and latches outside the propeller?

[dfgfdg7747]

@ranamuhammadatif

the circuit at the base of the case does 2 things. (1) it provides power to the primary coil of the air transformer located on the motor, and (2) it allows the user to manually change the speed of the motor.

This circuit could have been hidden but I chose to show it instead

[ranamuhammadatif]

@dfgfdg7747 What is the maximum rotating speed (RPMs) you managed with this? Did you use any LED driver IC or latch for the LEDs? Does a hall sensor work better or an IR pair? Are there any problems with an IR pair because I believe it does not give a proper transition but a fluctuating output the moment the IR transistor passes the IR LED.

[dfgfdg7747]

@ranamuhammadatif

Max speed around 40Hz with a 40 x 40mm fan. there is no led driver or latch for the LED's, only an npn transistor and even that is not really required. Both a hall sensor and an IR pair will work well and give a stable image, I used an IR led and phototransistor

[ranamuhammadatif]

@dfgfdg7747 Can I please have the schematics for the air core transformer driver ?

[dfgfdg7747]

@ranamuhammadatif

the circuit is in the electronics section of the soubry.net website I have mentioned in the description section of this clock (just under the video)

[ranamuhammadatif]

@ranamuhammadatif No schematics on that page. I have just tested a clock with 9 leds using an AT90s2313. I used a small DC motor. I used the shaft to supply the GND and an armature between the shaft and propeller circuit to provide the 5V for my circuit. Works fine.

Now I am building another one with an ATMEGA64 to drive 33 LEDs. I do not wish to spend too much time designing the air core power transformer circuit. Could you please give me the schematics for the power supply?

[dfgfdg7747]

@ranamuhammadatif

The schematic is there. Go to the Soubry website I mentioned in the description of this video. When you're at the Soubry website click on the electronics button at the top left of the page (it's between the mechanics and software buttons). You'll see links for the schematics for the air transformer as either .gif or .sch files under 'The base electronics' section (for the primary coil of the air transformer) and 'the propeller electronics' section (for the secondary coil).

[ranamuhammadatif]

@dfgfdg7747 I don't see details for the transformer driver. I need the exact circuit for the transformer drive. I am currently banging my head trying to read time from a DS1307. I have read it but it does not advance. Thanks for your cooperation. I just need a bit help with the transformer. I hate power power electronics.

[Moser86]

well done Rich... You finished it... What's the next project?

Gratulálok Rich... Befejezted... Mi a következő projekt?

[dfgfdg7747]

@Moser86 . Thank you my Hungarian workmate. Next project is a propeller clock spinning in a horizontal plane. (This clock spins in the vertical plane)
