World's First(?) Incandescent Analog Clock by adamlhumphreys World's First(?) Incandescent Analog Clock by adamlhumphreys
So, with everyone else doing nixie tube clocks and stuff, I thought I'd do something a little different since I like light bulbs on an analog face. :D

See the video here: www.youtube.com/watch?v=fXY0pr…

The times above, from the top left, top right, bottom left, bottom right are 7:17 to 7:20 respectively. The center light represents the second. All together it uses a little less than 10 watts when the lights are on. (Turned off with a switch.)

Please leave feedback! If someone else has done this and I overlooked it, please let me know! (The closest thing I found was the Bob clock.)

could you please share the electric diagrams or photos of how its made etc? i want to make one, maybe with leds

I wouldn't have a problem with that, but really it's just 12 pins connected to SCRs to drive the bulbs on full rectified pulsed DC. Making it with LEDs would be a world easier, (and how I made my LED Luna). But you could probably get away with using an addressable LED string and an ATtiny with a simple RTC (or a 1 PPS input from a standard clock motor driver). That'd be only 2 IOs at minimum. :D

Wow, cool!
I might want to consider putting that nifty thing on my wall sometime.

I don't think I have the money, though...

Also, does the middle bulb flash every second, or does it change in brightness as the seconds pass?

I understand. The last estimate I gave was $240. Still less than a typical plush. :iconajawkwardsmileplz:

It has 4 stages of brightness and fades in for a second, then fades out the next second. Sorry the video probably isn't all that clear. ^^

So how do you tell which is the hour an which the minute at a glance? In the last picture you said it's 7:20, but couldn't it just as easily be 5:35? And what happens when both the hour an minute are at the same number? Say, 12:00?

Fairly interesting, anyway.

adamlhumphreys Featured By Owner Jan 24, 2015  Professional General Artist
4:35? It's honestly not very apparent in the photos, but the hour bulb will always be the visibly brightest bulb over the minute bulbs. :nod:
When they're at the same number, just as any other analog clock, you'll only see one visible "hand," so only one bulb will be lit.

Much appreciated, and thank you much for the watch! :D I’ll try not to disappoint. :iconfluttershysaluteplz:

I hope to revisit this project again someday. I've since come up with a more efficient way to sample the line frequency both on the hardware and software side. I'd also like to use a switching power supply, but that would mean I'd have to change the timing to use transistors rather than SCRs to drive the bulbs. :eager: Right now the only light bulb thing I have in the works is a candelabra base display block to use along with my other medium base display blocks.

:XD: I used the ATmega328 in conjunction with the Teensy 2.0 (to as the in circuit programmer) and Arduino IDE for writing the actual program, (but I don't use their "digitalWrite/digitalRead functions, I read/write using the port directly with bitwise operators). :aww: I have big plans for my Luna plush. :3

Should make a heat clock. Touch to know the time! Or spray water. That actually sounds like a good idea o.o

adamlhumphreys Featured By Owner May 11, 2013  Professional General Artist
That would actually be pretty cool for the blind. :O A nice quite way to tell time rather than having an electronic voice talking. It'd probably be best to use 1/2 watt resistors for that. Not sure where spraying water would come in other than to wake someone up. :XD: But I am working on a greenhouse controller that I hope to do quite a few things. I'm waiting for the FETs and transistors I'll use to drive relays and whatnot to arrive now. :)

Way to waste batteries though. I wonder if there's some sort of an efficient switch to create bumps on (under) an elastic surface. Reels with a sliding magnetic core maybe?

I kind of want to get back into electronic again now XD

Well, an open analog clock would probably be sufficient. I suppose you've seen one of my more ridiculous projects: [link] :3

So the "minute hand" fades in and out depending on how close it would be to any given point? Like, I notice that at 7:17, the "3" bulb glows a little, but at 7:20, it's dark.

Very cool.
