Direct Drive Propeller Fans Are Dynamically Balanced For Quiet and Smooth. The required lines to drive all 132 LEDs are reduced to 12 by using the cross-plexing feature optimizing space on the PCB. ![]() The AS1130 offers a 12x11 LED-Matrix with 1/11 cycle rate. The devices can be programmed via an I☬ compatible interface. i was thinking of using 13V zener to cut "excess voltage" but haven't tried it yet. Propeller Accessories 3.17mm RC Aluminum Bullet Propeller Adapter Holder for Brushless Motor (Collet Type) - 1Pcs M5 Propeller Prop Nut Cap CW CCW for Emax. ADPs biometric timeclocks or biometric timeclock attachments do not collect. The AS1130 is a compact LED driver for 132 single LEDs. on the final board there will be different transistors(haven't arrived yet) but I'm not sure if transistor could be the problem. We have used Jon stanleys propeller clock as Reference design. all looked fine but when i put signals in transistor(on breadboard i used irlz24n), the output waveform Had huge spikes on rising edge scope outputs first two are outputs on mcu pins(5V) then there are mix of resistive load and tiny fan attached(i see no or very little difference) and last one is big 20W fan attached this is the point I'm stuck on because i have no idea why is the ringing there and how to get rid of it. the motor is chosen to be 12cm 12V fan(idea by ) and from same design i like the idea of air core transformer for power to the rotating board as for my part of this project i decided to base the "power supply" on the tiny 13 on which I'm using timers to generate 1x +-37,5kHz PWM for speed control of fan 1x +-37,5kHz PWM with duty cycle set to 50% just as square wave generator for IR led(I'm using integrated receiver) and 1x software based +-120kHz 50% duty cycle square wave for air core transformer(the value is just randomly chosen by me with "higher f=better efficiency" in mind) now there is button and led on board used for switching and signalling 3 modes just in case i could use them Schematics: OK so i have built this on the breadboard checked on cheap Chinese logic analyzer. The fan will show the clock in LED light while in propeller motion. For example if you convert you hex to binary you could betters see your digits.Hi, i have chosen propeller clock as a school project and i could use some help from more experienced people, that I'm sure i will find here for starters the project is few internet sources connected to something i think i like the most, but I'm open to new ideas. Project Code You can make the necessary changes to the following source code of USB Led fan clock and upload to the Arduino NANO through USB cable if needed. This led row is rotating at a rate superior to humans eye remanence. Thanks for your response, it was useful for us. Propeller Led Clock Arduino: A propeller clock, also known as a Persistance Of Vision (POV) display is based on a mechanically moving led row. The LEDs arranged in a row across the PCB turn ON and OFF at specific intervals when the system rotates to produce image of a character on the eye of the human watching it. ![]() The system has a high RPM motor which makes the system rotate. We tried to use Hall Effect sensor (HAL505) but it has low sensitivity, it did not work properly. Digital Propeller Clock with Android Override project is built around ATmega family microcontroller. Huge red 7-segment clock display soldered to backpack with all segments lit. RGB FUSION 2.0 Supports Addressable LED & RGB LED Strips Smart Fan 5 Features. For a wide variety of project ideas, check out the LED section of the Learn. ![]() Some people use and IR sensor, some use a Hall Effect sensor, but you need something.
