Watching the clock is, let's be frank, is horrible for the eye, but this old-school movie idea with leds is priceless. And so is the production, of course. I'm convinced to sub.

[@burgersnchips]

A second magnet 90° out of phase with the original one would tell this device everything it needs to know about the roataion speed of the motor, with a little clever programming this could sync up the face to a variable motor speed on every rotation.

[@cll1out]

This idea would be a more accurate version of what I was thinking. With even just the single index magnet, some mathematics and timing measurements could be involved to determine the RPM, wait for the motor to stabilize, and then "start up" the clock display. All the while keep measuring and readjusting the display to match inevitable but ever so slight variations in motor speed.

[@CXensation]

Interesting project. Could be modified to any analog instrument readout. Tachometer, Odometer, Voltmeter etc, but the motor should be rpm controlled. With 2 center rings for slide contacts, the supply connection rids off the onboard battery. With a bluetooth or zigbee addition, the processor could be remote controlled for various display settings, e.g. a true multimeter with several ranges. Using a vertical rotating (drum) display, you could even make an oscilloscope showing vaweforms, e.g. the old rotating cola-can project.

[@davidgiardini1275]

You don't need RPM control, you can measure the RPMs from the halll sensor and adjust the tun on timing. Didn't see the code but should be doable this way.

[@CXensation]

@@davidgiardini1275 Its do-able this way, but will give flutter on the readout, as the processor only can correct pr 1 revolution. A motor control using emv sensing is very precise and was often used in former echo-sounders using exactly this type of readout.

[@CXensation]

@@davidgiardini1275 Its perfectly do-able this way but will give flutter on the readout, as the processoer con only correct pr 1 revolution. With a motor controller using emv, as the former type echo sounder readouts used, it will be much more stable.

Super project, thanks, man!!!

[@lSeriyAl]

you should add time-correction var due to u havent RTC, so after 1 day of working your millis() will not equal a day. also if you plan to use this code for a long time, you should do workaround of millis() reset (due to sizeof(millis())) also if you use direct access to registers, why not exlude arduino.h using int main() {...} instead of setup() and loop() it will speed up code execution and its size

[@levistrnad2965]

do you set the time with the magnet? if not i dont see how this would be an accurate clock although its still awesome.

Hi Hobby Projects, I have built the "Arduino NANO Propeller LED Analog Clock " but the minute and hour hands do not display. I notice, in your code you've assigned pins A6 and A7 as minute and hour sensing pins, but this does not show in your schematic??? Am I interpreting the code wrongly, or is this just a forgetful omission on the schematic ???

I find this to be an interesting project. I look forward to assembling this project. As to some of the rude response by the know it alls, shame on them. I find your generosity in sharing your knowledge comforting.

[@Corbald]

You should use millis() to sync up your lights to your driving motor speed. define oldMillis = millis() in your setup(), then at the beginning of your main loop, define newMillis = millis(). Check to see how long it's been since the last loop with newMillis - oldMillis, then you can use the Hall sensor as the benchmark for your RPM. Adjust a pause to taste and then assign oldMillis = newMillis at the end. Now you can run your motor at it's optimal speed (read: quietest) and have the arduino adjust it's display rate to match.

[@protonx80]

i was going to post exactly what you are saying ... but you said it in a much better way ......there should be no need to adjust the speed of the motor to complete the display ... only to optimise the rotation of the motor

[@Corbald]

@Jason Alannah I'm only a hobbyist coder, myself, but I took a look at your code, and you're doing a lot of bit shifting, which I'm not very good at. I'm guessing it's to do with the LEDs. So without comments, it's hard for me to tell what's going on. I see some built in delays, which look too precise to be anything but timing for the clock display. I can only tell you how I would approach the project. 1) Divide the entire 'image' to be drawn into slices, say 36 to make the maths easier. You can do this with cartesian -> polar coordinate mapping, or just hand write each slice and stuff it in an array during Setup(). If you do the latter, you'll still have to account for the position of the hands of the clock during runtime, but you'll have to do that either way. 2) Hall effect sensor triggers the beginning of a 'frame' (via the interrupt) and polls the time (millis()) into newTime variable. 3) newTime - oldTime = elapsedTime. This is the length of time it took the _previous_ loop to do the entire rotation. 4)elapsedTime / 36 = sliceTime. You want sliceTime so you can track how long each slice is taking on average. 5) "while (millis() - newTime)/i < sliceTime" -- Here is where we're delaying, between each slice. We want each slice to last 1/36 of a 'frame' or full rotation. 6) don't forget to set oldTime = newTime! pseudocode (I don't even know what language I think in, anymore!): Setup(){ oldTime = millis(); // something to start with ### // register an interrupt for the hall effect sensor(I don't remember how with arduino, google it) } Main(){ while true { ### // figure out the proper time and create the clock face and an array of slices to draw it. ### // Probably only needs to update once per second. } } Interrupt(){ newTime = millis(); //fetch the current time elapsedTime = newTime - oldTime; // get the time it took to do the previous loop sliceTime = elapsedTime / 36; // the length of time each slice should take for i = 1 to 36 { // do each slice ### // draw a slice while (millis() - newTime)/i < sliceTime { // delay until the current slice should have completed pass; } } oldTime = newTime; // update oldTime } It's rough, but that's what I came up with off the cuff.

[@pemulungelit9050]

Hey bro, what if we change the battery with wireless charging?

[@SteveJones172pilot]

@@pemulungelit9050 Thats what has stopped me from doing something like this.. I want it to be run by wall power, which means either using a slip ring, which complicates the mounting of it, or to do some kind of inductive charging.. haven't spent any time figuring it out.

[@GyroGearlooseHelis]

A few "upgrades" I intend to do when I build this: 1) Wireless interface -- a simple 433MHz serial line would be simple enough to get data in. A slip-ring could work, but there's more friction/noise issues. A full bluetooth serial would be overkill. Clock could be set, and text could be changed on the fly using that interface. 2) Power -- You have a rotor and a stationary magnet (aka a generator?), so just put a coil and a diode on the rotating board, and you can suck in pulses of power. Replace battery with a largish capacitor and voltage regulator, or shove power into the battery with a voltage cap to keep from overcharging. Nano already has a Vreg, so I'm going to see if just a coil/diode/capacitor is enough. 3) Optional: Time retention -- this design is terrible for wandering time. Add an RTC chip to maintain the time while running, and possibly between runs. Or, if #1 is implemented, have some external control re-setting the time periodically. I'm probably going with the updates 4) Code optimization -- I know this is bitshifting for performance, but this code is obscure. I'll rework it to be a lot easier to read and maintain. That snipe aside, THANK YOU for the starting point from which I'll be working -- huge jumpstart to the effort! 5) I'm using a ProMini -- if you can't use the USB interface runtime, no reason to have it onboard after programming. 6) Adjustable balance -- since I'll be playing with adding/removing things, I'll add a longitudinal bolt and two nuts (to seize one another) so the CoG can be adjusted easily and precisely for balancing/noise. One change that seems obvious but probably isn't good -- Synchronizing the display delays to RPMs. Yes, I had the first initial thought that controlling the RPMs wasn't a good control mechanism, but adjusting delays could cause a more ragged display. Assuming the (calibrated) motor holds speed fairly stable once spun up, static delays probably produce a crisper result. If not, you NEED to adjust delays at all costs. I might play with this, but I *expect* to not want the self-adjusting delay.
