My computer notifies me when it's bed time (12:30). So I'm usually in bed by 2am. Via central heating, bedroom rad comes on 12:00(-01:30) and turns off when room up to temperature (24°C) (Stat set at 18)

"Should that be making scrunching noises?" Well, it's a BigClive vid, we'd be disappointed if it wasn't.

Ohh, I was considering one of these recently. Thanks for the upload, BigClive.

Nicely designed and manufactured clock.

I've had one of these (but white) on my office wall for 2 years now. I love it.

Great walkthrough as ever Thanks for sharing 👍😀

Your half-ass Samsung phone overhead camera rig gives a more readable picture than that multi-thousand dollar microscope Dave Jones uses. Love it. That's a cool little gadget. A cheap low current replacement for my circa 1980's Radio Shack Big LED clocks around the house. Plus, I could probably add in a "synchronization" circuit using an ESP8266 to reset my clocks around the house without having to run around like a fool pressing buttons.

I've got one of those by my tv. I keep it on low intensity and it's still really bright. It runs a little slow, loses about a minute a month but I still like it. Glad to see what it looks like inside.

I have a clock like this that I use when I'm stage managing live stages so the artist can see what time it is at a glance, it's very useful.

What I hate is when they lead you from site to site for a data sheet, then want to charge you for it. That really makes me mad.

That clock would would look incredible in a magic mirror :)

Very nice clock thing!

I think it could be used as a counter, with a remote to add points to the left or right , like a basketball score display, granted many possibilities but thats what popped in my mind as you disassembled it, big respect to the big clive up north thats why i spread the word on your channel, and as gizmo said "BRIGHT LIGHT" need to find the lighting technician...

For some reason from the thumbnail I was thinking and hoping it was a flip-disk style mechanism.

It's very strange that having an ADC in the microcontroller, the developers of this clock didn't implement automatic brightness control based on ambient lighting, measured by an LDR or a photodiode.

Yes, also I assume that extra LED is used to perform that, because despite what it's made to do, LEDs technically produce a voltage when exposed to light since they are really the same thing as solar panels, I assume they measuring the voltage of that led to sense the amount of light around the clock

I tested a red-amber-ish and a green one as backstage clocks a few times. Either one works okay, but the lack of seconds makes them of limited use, for backup, or for anything not too important. For serious time-keeping, better set up a Pi or something with an expendable TFT screen. Gets you seconds, networking and communication, VESA bracket mounting … the lot.

Hi Clive. Wondering where I might be able to find (ir not get the parts and get help to build) a LED/LCD ditital countdown timer? Something smaller, not for the use on a wall in a room, but something that I can use for a gaming or casino table, as a bit of a "time left to act". Ideally, Iy would be awesome to wire 2 or 3 built INTO the table, such as the playing surface and from the admin or dealer section, manually configure all clocks simultaneously to countdown. Any ideas on how I could achieve something like this? No player interactivity, no buttoms at the location of the time (wired and extended elsewhere) and also no audio/alarm required.

I have one of these, I took mine apart and fitted some green window tint to the panels, as even on low, it's still chuffing bright! Great clock though, very happy with mine. Oh, I also broke that post as well, no biggy.

"15th of the 12, someone was working right up until Christmas there". Makes me wonder if working a software dev job really means I need to be here right up until Christmas Eve... Anyway, great video as always Clive! This product seems to be very well built!

Do you think the dome on the front could be for a photoresistor (LDR) for auto-dimming?

Bottom center LED is a decimal point to allow displaying numbers instead of time. If the far left LEDs and the center bottom one were populated, then it'd be able to display 88.88

The one downside I see with that constant current intensity regulator for the LEDs is that the brightness might modulate depending on how many segments are lit.

@johnfrancisdoe1563

4 жыл бұрын

Veraxis Indeed. Something needs to adapt the current selection to the number of lit segments. So either the regulator can be set to 28 different currents or there's a dummy load with 28 values, or it's actually multiplexed to light one segment at a time. Note 28=7+7+7+6+colon.

I don't even want one, but finding out how small those clocks I kept seeing listings for really are makes me want to make one that actually is that big.

Hi this clear stuff on front of number could be Light Enhancement Film?

I have three of these clocks...one with RED LED's, one with GREEN LEDs and one with white LEDs. Several of the segment leds on the white clock went bad after a year and are very dim to where you can't really tell what time it is, so I replaced it with a green LED clock. I use two of them on my monitor at work, one for local time and one set to UTC.

I'm just going to probe the colon, hold still please sir! Pure gold Clive

There are many microcontrollers with a built in real time clock circuit. Even some without it can be made to serve the purpose very nicely. 32786Hz as a clock on your processor doesn't lead to high performance but it is good enough for being a clock. It could be a nice home project for someone to make a really big version

So if I were to wire-in a low value pot in place of R9, say 100 ohms, it should be possible to turn the brightness down further? - I have a green clock and its too bright at night even on its lowest setting..

Bought one. Green. Not disappointed

The lens could be for auto light level. A very useful feature. I bet it's really over bright at night.

Hi Clive, I can't help but wonder if that little domed window might be for an ambient light sensor, in a different incarnation? However, it also would seem to match up, pretty much, with the back of the buzzer - can't see how that would be relevant, but maybe again, in a different version the buzzer might be on the component side of the board, with a small grille or aperture in the fascia to allow the sound to emit from the front? Oh, just a thought. . . . . Didn't they have a girly pink version? 😁

I bet the hidden screw is for mechanical stability when attaching/detaching the stand

Are you sure that "IR Receiver" channel isn't actually a dusk sensor? Would make more sense, and given the LEDs have variable brightness it might have been a nice feature, were it implemented. A photoresistor in place of one of the upper lefter 0r resistors?

sound is great clive

I wonder if that chip has code in flash or in ROM? The 'data sheet' said it had both, and also had the magic number 8051 on it, so the CPU's completely standard. It'd be interesting to try and reverse engineer and reprogram. There are some interesting looking test points near the CPU which might be worth investigating.

There's no need to include an RTC chip on a clock. It's very trivial to set up an interrupt timer to generate i.e. a 100Hz (or some other useful rate) interrupt, then just increment some counters to do your timekeeping. Usually I set the interrupt to 1KHz or so and do the LED multiplex refresh and timekeeping all in the same interrupt. This isn't so easy to battery back, but you could run the micro on both via diodes, and have the LEDs just powered by the DC in.

I would speculate that the display has the potential to show TEMPERATURE -- and the extra un-mounted LED would serve as a decimal point. Given which, the temp display must have been meant for Celsius only -- since more than 99.99 degrees could not be displayed. Conceivably, the little window could be for a light sensor. That would allow the display brightness to vary with ambient light conditions.

Is the window for auto dimming at night?

I have this clock, bought for six quid from a Facebook Marketplace seller. All seems ok except that on those two left hand numerals, ie the hour digits, the bottom right little white bars will suddenly change to very bright without any prompting, and will only revert to normal if the whole clock is twisted, when it will click and those two pesky bars revert to normal. I either twist it or tap it smartly on my knee. When these two bars illuminate so brightly the clock is useless as you cannot tell the hour. It's a shame as although it cost so little I had hoped it would be as good as it is in the videos and adverts, so am a bit disappointed. I bought it as a working item, but cannot be bothered to drive back to return it to the bloke, who surely was aware of this fault. Ah well, a lesson bought is a lesson taught, or whatever.

For data sheet archive. Maybe alldatasheet.com. Just be sure to have an ad blocker running. Have a whole folder of data sheets for stuff in my random salvage box that came from them.
