Propeller Clock © Copyright 1997 Bob Blick

An Analog & Digital propeller clock i made!
It isnt Real its just because your so awfully slow!!! ;-)

based on an afterimage phenomenon, ie the reaction slowness of the retina, the illusion of reality our brains are "lying"
Picture's made 12-12-1997 by Luberth Dijkman Clock was actually running 2 weeks earlyer
Bob Blick started the propeller clock
This clock is based on Don Zehnder's Clock. He made the first analog version (+/- 1996)

Above Don Zehnder's first analog version
I saw his analog version and asked if i could have his code
and i build my version with a bit more LED's to circle center and an outher circle LED in 1997




Simple slip spring ring to get power on rotating propeller




Some technical information!

Assembler Code written by Don Zehnder
This clock has 14 red led's & 1 Green
(red diffused 200 to 300 Mcd Kingbright L-53-SRD-D)
I prefer difused LEDs as they are better vissible from the side(angle)
Bright LEDs are perfect only when you look/stand straight in front of it
Tommorow (13-12-'97)i wil try red diffused 700 to 1000 Mcd Kingbright L-53-SRD-G
Nowadays(2002)a large choice, back in 1997 it was a bit harder to get ultra bright led's
The propeller is mounted on a "Mecano"(Kid's metal construction) base
7 outher led's are controlled direct from pic's port
8 inner led's are together switched by a transistor
The moter comes out a Philips VCR VR 2022 two of them in 1 recorder
A 4mhz pic16c84 is clocked at 10 mhz
Later i made a brush/slipring the balbearing give too much errors
Rotation pulse is given by infrared gate
Time setting is done with a reed switch (when a magnet apears near propellor time speeds up)
Luberth Dijkman Andijk Holland 12-12-1997


Next ASM code's must be changed for use with Bob's flat clock layout
Pay attention Pic running @ 10Mhz And include's p16f84.inc

Don Zehnder's Analog & Digital Clock code

Don Zehnder's Analog & Digital Clock and Scrolling text code

 

 



Above a modified version of Don Zehnder's JAVA clock
Changed the outerline/circle of analog clock to seconds circle
Thougt this was a nice feature
Fun to see it now(Years later in april 2005) copyed in a commercial clock
link to innovativedesign.com

the outher circle tick looks a bit like the arcade game i saw in the 80's LadyBug
a pacman alike game, actualy better then pacman
the game console whas standing in a sportskantine nearby and was verry populair
In the game LadyBug, every time the outher tick line flows over a new bug is released
Wanna play this LadyBug game on a emulator an see why its better then PacMan
you can also see where i got the idea from the outher tick line

Ian Paterson Spoke POV
POV stands for Persistence Of Vision. It’s a term that's been applied to devices that rely on the eye's tendency to continue to "see" an image for a short time after it has disappered. This is also what causes the apparent blurring of objects that are in motion (like an airplane propeller).

Alan's electronic Projects Rotating LED display


Fan spins your name in lights Computex 2006 Cheap glory By Simon Burns in Taiwan: Thursday 08 June 2006, 10:28 FANS WHICH use rapidly rotating LEDs to display text have been around for a while. But so far, they've been limited to a word or two pre-programmed into them by the manufacturer, plus a temperature display. By next year, you could be seeing your own name in those rotating lights. Taiwan-based Polo Tech, which claims a patent on rotating LED fan display technology, has plans for a USB-programmable model, although the release date is undecided, company representative Alice Wang said at Computex in Taipei. Users will be able to use an internal USB connection and software to change the fan display in real time to show their name, or any other text or simple graphics. At the moment, Wang said, changing the text requires a whole new IC, so is only feasible for large quantity orders. The fans generate the display with a rotating stick of circuit board with a vertical line of LEDs on it. This is mounted on the fan's axis, and spins as the fan spins. Polo Tech's driver IC can also handle simple animation, and even colour changes, given suitable LEDs. The IC also handles the precise timing calculations required to keep the display steady. Your name up in lights. Coo. To avoid excessive flicker, the rotation speed needs to stay above 2000 RPM, Wang said. The display remained visible even in the bright interior lighting of the Computex hall. At Computex, the company displayed its original $7 medium sized fan – which appears to have been taken up by companies including Thermaltake and Foxconn – as well as a larger prototype (see photo)

Rotating display system, United States Patent 6856303

A pixel-based display utilizes persistence-of-vision to sweep text and graphics in a cylindrical plane, including time and date, custom messages and animations. The display is generated from a light array with a column of modulated light emitting elements, which is mounted on a rotating display assembly. Power and data are combined on a fixed control assembly and inductively coupled to the display assembly. A control assembly processor interprets a display application language that describes display-specific tasks to generate command, mode, character and graphic data for the display assembly. The control assembly processor also reads a trigger position sensor and adds a trigger delay to generate a virtual trigger command, which provides for flexible display positioning and scrolling display effects.

Mechanically Scanned LED Clock

my version off the clock made in 1997 well before all the commercial items availeble today

saw Bob Blicks clock web page in 1996/1997
thougt it would be much to complicated to build for my lower technical school brain
but the teacher Bob had it well described on his webpage
so i gave it a try and stunning miracelous it worked
© Copyright 1997 Bob Blick -> Link to Bob's page's
Seven light emitting diodes spin, giving the illusion of numbers in the air.
How this clock works:
A motor spins the "propeller", and a small microprocessor keeps
track of time and changes the pattern on seven LEDs with exact timing to
simulate a 7 by 30 array of LEDs.

It is an illusion, but it works.!

I used brushes for the print power suply 6V=
Above the white plastic brusholder there is a glas reed switch
switched by 1, 2, 3, or 4 magnets
wich gives the PIC it's rotation pulse
So the clock could display on 1, 2, 3, or 4 side's

    can write to a different file. or you can keep on writing to the same
    file. It wasnt much of an update, but its kind of nice since you can
    just copy it as is into your asm code. OK, well, here's the program.
    Change it as you will to be better suited to people or if you want to
    clean up the code a bit, since it has your name on it. OK, take care.

    PIC Microcontrolled 'magic wand'

    7/12/1997 Copy from Barry Carter's page!!!

    Barry's page used to be located at http://www.bazginge.demon.co.uk/ click here to go WayBack

    Interested in my magic wand? Read further.

    I have constructed a 'magic wand'
    which will display a message in mid air when waved in front of you.
    The wand is not very easy to see in daylight, but many people can see it.
    I have constructed this with little components so it is very cheap.

    Design of wand
    NOTE: MCLR Pin5 should be connected to +vdc (+5v DC)

    The Hardware

    I made my wand out of a maplin project box order no FT32J
    This is a small probe box and cost approximately 1GBP.
    I drilled 5 holes for the LED's and made a small PCB to fit inside.
    The box is *Just* big enough to squeese a 9V battery in, which supplies the PCB with the power.
    The scrolling sensing is done by a tilt switch/ push button.
    If a tilt switch is used, you will have to juggle with it for optimal performance.
    In place of the tilt switch, you could put a button mounted on the case, which when pressed will triggger off the display.

    The construction

    The project is fairly simple, the only problem being that all of the circuit has to cram into a relatively small box. Follow
    the steps below, and the scroller will work.
    Steps:
    1) Get all of the components (see below)
    2) Assemble the components on a PCB or Veroboard.
         Use the circuit diagram to build it.
    .... 2.1) Place the smallest pieces on the board first.
                 Do it in height order. i.e links first then resistors caps... Put the programmed microchip in first.
    .... 2.2) Program the microcontroller with the message.asm file.
    .... 2.3) Place the programmed chip into the board.
                 The chip should be set to Watch Dog Timer off (WDT) and oscillator mode RC.
                 You can download pictures of the Simple PIC programmer from my web site (www.bazginge.demon.co.uk)
    3) Drill all of the holes in the box.
        The holes should be:
         5x LED hole
        1x button hole(optional)
        1x off switch
    4) Push the PCB into the box, with the LED's pushed into the holes drilled.
        Attach the PCB to the bottom of the box
        with either tape/velcro or PCB spacers depending on the height of the LEDS from the bottom of box.
    5) Put battery in box making sure that it is held in tightly.
    6) Put the top onto the box. Turn on and wave around
     
     

    The components

    Resistors
    R1 100K Metal film 0.5%
    R2 12K

    Capacitors
    C1 100n Ceramic cap
    C2 100n Ceramic cap
    C3 100uF Electrolytic
    C4 10pF Ceramic cap

    Semiconductors
    IC1 PIC16C84 04 (4Mhz)
    IC2 LM7805 voltage regulator

    Misc
    5x Red LED
    1x push to make switch
    1x toggle/slide switch

    Software
    The software is very simple indeed. the are mainly four parts to my code.

    1) The declarations
    2) The message to be scrolled
    3) The letter output routines
    4) The wait routine

    Here is the code below.
    assembler source message.asm
    Hex File message.hex (default message hello)
    message.zip a .zip file of the whole message project.

    My Daewoo (Nexia) car wheel is 57CM in diameter ;-)
    60Km/H = 1000M/Min / (3.14 x 0.57M)= 558,72 rotations per minute at 60Km/H
    thats 559rot/min /60seconds = 9.3 displays per second(what does youre telivision do?(something like 30 pictures per second))
    should give a visible display => but not optimal
    but what if you put leds on 2 or 4 sides
    this should give a good display

    Mechanically Scanned Laser Display


    laser beam laser pointer.
    The device uses one light source (a laser beam) and mirrors to scan the display surface.
    The main components include: a laser diode from a keychain pointer,
    a cassette player motor,
    a PIC17F877 board with the associated circuitry,
    a power supply, and an ingenious head with mirrors.
    The head is an octagonal prism, with a small mirror on each lateral face.
    Each mirror is mounted at a different angle,
    giving different reflection angles for the laser beam.
    The mirrors reflect the laser beam, creating a raster.
    The raster is modulated by turning on/off the laser beam.
    The microcontroller board receives one pulse per rotation from the rotational speed sensor
    and calculates precisely the moment for turning on/off the beam.

    it is not real, it is just because you are so slow! ;-)
