Core Innovations Galileo: An Alarm Clock So Weird, It Was Made for Me
When I discovered this alarm clock a few weeks ago, I almost didn’t believe it existed. It has a cute, simple exterior with green accents and an analog clock face. Yet somehow it’s also a Bluetooth speaker, an FM radio, a nature sound machine, and a phone charger. Say what?!
And the more I looked at this clock, the more baffled and intrigued I was. It seemed to violate every known principle of alarm clock user interface design. Most clocks try to mimic one another in features and user interface. But not this one!
So I had to buy this thing. And I can confirm (a) it exists, (b) it works (not always well, but it works), and (c) it is even weirder than I expected. This might be tied with the Philips AJL305 for the weirdest alarm clock I’ve ever seen in my life.
So come on. We have to talk about this thing!!
About Core Innovations
Core Innovations is a small American electronics manufacturer. They make everything — alarm clocks, speakers, TV sets, computers, portable DVD players, projectors, and on and on and on. They also make pool toys, because reasons. Actually, the reason is that Core Innovations has a sizable market for kids’ products, electronics and otherwise. The company has a license to make products for many kids’ media franchises (Baby Shark, Blue’s Room, CoComelon, Ryan’s World, etc.). (And no, we are not going to go down the rabbit hole of the Baby Shark alarm clock, or the PBS Kids tablet/DVD player combo...)
I’d say the clock we're discussing, the Galileo (model CTAC02), is somewhere between Core Innovation’s kid-facing and adult-facing products. The endearing design, plus the soothing sound and night light features, remind me of other kid-oriented alarm clocks. But I hardly think cute, colorful design should be restricted to kids’ products, and indeed, the press photos of the Galileo show it in adults’ bedrooms. So this alarm clock is approved for adults!
Based on the packaging’s copyright date, the Galileo was launched in 2022. It appears to be the successor to an extremely similar alarm clock, the Chronis (model CTAC01), which has a different shape but the same clock face and the exact same controls. For the sake of not overwhelming myself, I’m going to focus this post on the Galileo!
I’m not sure that Core Innovations products are pinnacles of quality. I purchased my Galileo for about $30 new, and it came with a slightly scratched-up front panel and a crumpled instruction manual. That said, it is in working order, which is the most important part!
Design and controls
The Galileo has a friendly, rounded white exterior that is capsule-shaped. It houses a minimalist black clock face with no digits, just markings for each hour. The clock hands are green and the alarm hand is red, and the green is echoed by the two little feet that the clock stands on. A small LED hides within the top of the clock face to illuminate it when needed.
Looking at the front, you’d never guess how many features the Galileo has. That’s because, except for the top-mounted snooze button, all the controls and features are hidden on the back. Here you’ll find three rows of controls and components, flanked by two stereo speakers.
The top row includes six white buttons: volume down, play/pause, volume up, sleep sounds, mode, and previous/next. (Previous/next is one button, not two. Trust me, we’ll be talking about that.)
The middle row includes two small dials: one to rotate the clock hands to set the time, and the other to rotate the alarm hand to set the alarm time.
The bottom row includes a whole bunch of random stuff. There’s a power on/off switch. Then a USB-A power output port. Then a micro-USB power input port, with a status LED to the right. Then a 3.5mm audio in jack. Then a pinhole-sized reset button, which you press with a paperclip or other tiny object. Then an alarm on/off switch.
I do kind of love how the rows of controls are almost ombre and color-coded: the white buttons, then the gray dials, then the black ports and switches and tiny holes.
Power in, power out
I’ve discussed before on this blog how, typically, there is a dichotomy between AC-powered and battery-powered alarm clocks. AC-powered alarm clocks stay constantly plugged in, and they usually have power-hungry features like music playback or night lights. Battery-powered alarm clocks usually run on disposable batteries (like AA or AAA batteries), and they usually lack power-hungry features or gimmicks so that they can last years on a single set of batteries.
I’ve noticed more clocks recently that defy this dichotomy. Now there are a few clocks, like those from Mudita, IKEA, Lexon, and La Crosse, that run on a rechargeable battery. You plug the clock in every few weeks or months, and then it’s ready for anything! These clocks are handy because they eliminate the waste of disposable batteries, they have the battery capacity to handle power-hungry features like music playback, and they retain the go-anywhere versatility of a battery-powered device.
Taking advantage of these, uh, advantages, the Galileo is also a rechargeable clock. It has a 2000mAh non-replaceable rechargeable battery. To charge the clock, you connect a power cord to the micro-USB input port on its rear panel. The status LED flashes red during charging and illuminates solid red once fully charged. Core Innovations says the battery takes 2.5 hours to fully charge (not bad!) and can power the clock for up to 10 hours of audio playback (also not bad!).
I’m not sure what the battery life is like when the clock is just keeping time. And that leads to an interesting quandary, and my first criticism of this clock. What happens when the battery dies during the night? The Galileo’s status LED is on the rear panel, not the front, so even if it flashes to let you know the battery is low, you won’t see it. Does the battery just die and leave you stranded in the morning, when your alarm was supposed to go off? I don’t know. I haven’t owned the Galileo long enough for it to actually run through a full charge, and in fact, I suspect it can run the clock mechanism off the battery for a ridiculously long time. But if you own this clock, you’ll probably need to make a habit of plugging it in periodically, to make sure it never dies at an inopportune moment.
Interestingly, the Galileo also has a USB-A port for power output. These ports are common on modern alarm clocks. The idea is that you can connect your phone’s charging cable to your clock, which is already plugged in, rather than needing to find a power brick and a second outlet. (I personally don’t recommend using these USB ports, because charging your phone using unauthorized devices can potentially damage your phone or void the warranty. But still! The feature persists nonetheless.)
What’s weird about the Galileo is that it’s battery-powered. Typically, alarm clocks that can charge your phone have to stay plugged into the wall, so that charging your phone doesn’t run down any kind of battery within the clock. But I confirmed that the Galileo’s power output works even when the Galileo is running on batteries. (See the photo below, where my booklight is charging off the Galileo's battery.) The Galileo will discharge its own battery to charge your devices, making it a bit like the world’s weirdest power bank!
The many faces of analog clock faces
Traditional analog alarm clocks have fully mechanical timekeeping. A quartz crystal or other such oscillating device causes the clock hands to advance a tiny amount each time a set interval of time passes. Usually, that interval is a second, so the clock hands advance every second. When the clock hands intersect with the alarm hand, you hear a “click” sound in the mechanism, and that click triggers the alarm to sound. These clocks keep time from 12:00 to 11:59 without distinguishing between AM and PM. So you set your morning alarm for 7, and then you turn it on after 7 PM, because otherwise it would sound at 7 PM (as the clock has no concept of “AM” and “PM”).
There are a fair number of alarm clocks that merge an analog clock face with digital features. Some clocks, like the Casio TSA-80 and TSA-81 (below left) that I threw shade at recently, are fully mechanical, except that the mechanism triggers a digital device to play digital alarm sounds. Some clocks, like the Aiwa FR-A705, RCA RP5620 (below middle), and Philips AJ7000, keep time digitally and show the time on a digital display, but the digital display shows a depiction of analog clock hands. Some clocks, like the Nanu Arc (below right), keep time digitally and allow you to set the time on a digital display, but then use motors to rotate the clock hands to match whatever time you digitally set. And some clocks, like the Timex T318S (which I hope to blog about soon), have a digital clock with digital display that runs basically all the features (including the alarms), and then a separate fully mechanical analog clock that lives within the same housing but doesn’t communicate with the digital system at all. Note that all these systems, except the first one that the Casio clocks use, are able to track AM/PM because the timekeeping is done digitally.
Of course, the Galileo uses the first design that I mentioned, the one that the Casio clocks use. This means the clock is entirely mechanical (with no AM/PM), and then it activates a digital system as needed to play the alarm sounds. The difference is that the Galileo has a whole lot more digital brains than those Casio alarm clocks, which cannot play music or nature sounds or charge a phone. For a clock with this many digital features, I’m surprised by how low-tech the clock itself is.
One challenge with analog clock faces is how to illuminate them in the dark. Core Innovations clearly put more thought into this issue than Sangean did with the RCR-29 (said with disdain and spite)…but even so, the Galileo doesn’t exactly nail it. There is an LED light (below left) that you can turn on, and then it will illuminate the clock face indefinitely until you turn it off. But it’s horrendously bright. So it’s great if you need a night light! Less great if you actually need to sleep.
But Core Innovations has a backup plan! The Galileo also has glow-in-the-dark clock hands (above right), which are way less bright and sleep-disrupting. This would be a perfect solution…except that the glow-in-the-dark effect fades too fast after the room gets dark. It definitely wouldn’t last the whole night, so I can imagine waking up at 3 AM and being utterly unable to read the clock display, at least without blinding yourself with the LED light.
The power switch
Most alarm clocks cannot be turned “off” per se. They may have an on/off control for specific features, like music playback. But the entire device cannot be shut off without unplugging it or removing the batteries. Alarm clocks will typically keep and display time for as long as they receive power.
But remember, the Galileo has an “on/off” switch on its rear panel. What does this switch do? The instruction manual doesn’t say.
As far as I can tell, the Galileo has a digital “brain” that operates several of its important features, like the radio, the Bluetooth, the aux-in, the nature sounds, and the alarm sounds. This “brain” is essentially Frankensteined to the rest of the Galileo’s workings, including the fully mechanical clock mechanism. (We do love a mechanical mechanism.)
The “on/off” switch turns the Galileo’s “brain” on and off. When you slide the switch to “on,” the Galileo plays a power-on melody, and all of its features become accessible. (Though no audio immediately begins to play, which makes this switch very different from a typical on/off control for music playback.)
When you slide the switch to “off,” the Galileo plays a power-off melody, and everything gets extremely weird.
When the switch is “off,” the FM radio, Bluetooth, aux-in, and nature sounds are inaccessible. You also cannot set the alarm sound or the preferred nature sound. This makes sense, because all these features are controlled by buttons and appear to be driven by the digital “brain.”
But even when the switch is “off,” the clock continues to run. This makes some sense. You wouldn’t want the time to fall behind whenever you shut this switch off. And the clock mechanism isn’t driven by the digital “brain,” it’s driven by a little motor. So the motor keeps running and the clock keeps ticking. (An aside: The clock doesn’t actually tick, it makes a much-much quieter and more rapid sound to drive the clock hands’ smooth movement. Normal people won’t be able to hear this sound. I can absolutely hear this sound.)
If the clock keeps running when the switch is “off,” you might think the LED light that illuminates the clock face would also keep running, so you can check the time. But it doesn’t. The LED light only works when the switch is “on.” But the USB-A power output port? That still works when the switch is “off.” So you can’t check the time, but you can charge your phone. We’re so lost in the sauce here.
And this is the part that really kills me. It kills me dead. What happens with the alarm when the switch is “off?” Well, it sounds. Of course. Except something hilarious happens.
When the switch is “on” and the alarm time is reached, the alarm sound plays. When the switch is “off” and the alarm time is reached, the power-on sound plays, and then the alarm sound plays. And when you stop the alarm, the power-off sound plays. Here's a demonstration (preceded by the power-off sound as proof that the clock is "off"):
This makes me think that at the alarm time, the Galileo cuts its digital “brain” back on, so that it can play the digital alarm sounds. And because Core Innovations was kind of lazy, the Galileo still plays the telltale power-on and power-off sounds that signify when the “brain” is being reactivated, then disabled. (Which makes for a slightly weird alarm experience, because you hear this random melody before your chosen alarm sound.)
So in short, the “on/off” switch turns off most of the clock’s features, including the clock face LED light, but keeps powering the clock mechanism, the power output port, and the alarm. Got it?
THIS IS SO ILLOGICAL AND BIZARRE. There are many devices that have “on/off” switches. But usually, the device is completely off when the switch is set to “off.” The Galileo’s switch is more like an “on/kinda on” switch.
And the thing is, I don’t know why anyone would even turn the clock off. I mean, you can’t even access the LED light when the switch is set to “off.” So why not always leave it “on?” And why did Core Innovations even include this switch in the first place?
They may have included the switch because the Galileo is rechargeable. Maybe leaving the digital “brain” on results in phantom battery drain, but turning it off conserves power. But they don’t mention this in the instructions, so even if that is the reason, no user of this clock would know that turning it “off” is a good way to conserve power.
Or they may have included the switch because the Galileo is portable, and turning it “off” prevents accidental button presses when it’s stored in a bag or suitcase. But I feel like a “key lock” or “hold” switch, similar to other devices, would accomplish the same thing (more obviously than the current switch does), without needing to fully disable the clock’s digital “brain.”
The whole thing is massively baffling. No wonder Core Innovations doesn’t even try to explain it in the instructions.
Loud enough for you?
The Galileo has a digital volume control. This means that the volume is adjusted in steps that are predetermined by the manufacturer, rather than adjusting on a continuum from 0 to the maximum.
Unfortunately, Core Innovations selected the volume steps poorly. Specifically, the lowest volume level is RIDICULOUSLY LOUD.
But there’s a workaround. If you use the Galileo as a Bluetooth speaker, you can turn the volume down from your phone past the lowest volume level accessible from the buttons. Then, as long as you leave the clock powered “on,” it will remember this new volume level, even for features like the radio or nature sounds that have nothing to do with Bluetooth.
So the Galileo is capable of low volume levels. You just can’t access them without jumping through hoops.
Cool! Awesome! Fabulous!
Here's a demonstration of the volume issue. First, I play the nature sounds with a low volume level that I had previously set from my phone via Bluetooth. Then I turn the clock off and back on. You'll see that I can't return to that low volume level via the buttons on the back of the clock.
I’m not sure if the alarm volume is fixed or corresponds to the current volume setting. (This would be easy enough to check, but I don’t wanna and therefore I’m not gonna.) Amusingly, if you want a quieter or louder alarm, you can choose a different alarm sound, because Core Innovations managed to record all the different alarm sounds at different volumes. (Now that’s quality!)
Look, ma! No screen!
Most digital(-ish) alarm clocks have a screen so you can change their various settings. Even the Nanu Arc, which has an analog clock face, has a tiny secondary screen to make time and alarm adjustments easier.
The Galileo has no screen. Even though it has buttons and plenty of digital features. So how do you know what settings you are adjusting?
The Galileo tells you, because it can talk! (Somehow, that is the least interesting feature of this alarm clock, which tells you something.)
The Galileo has a “modes” button on the back. When the power switch is “on,” the clock sits around in what we’ll call “standby mode.” Nothing happens in standby mode.
Each time you press the modes button, the Galileo switches to a new mode in the following sequence:
FM radio > Bluetooth > Alarm sound selection > Nature sound selection > Back to standby mode
This is a slightly weird setup. FM radio and Bluetooth are playback features that you might want to have on for a long time. But the alarm sound and nature sound settings are things you’ll only spend a few seconds adjusting. So bunching all these together as “modes” is a little odd.
Each time you press the “modes” button, the Galileo verbally announces which mode you have entered. The video below demonstrates this process, and also includes a demo of the power-on and power-off sounds. WARNING: This video includes a sudden loud noise (radio static) that I will discuss further in a few paragraphs. I recommend playing the video at the lowest volume level available.
While in each mode, you can click the “prev/next” button to advance to the next option, or you can double-click the button to go back to the previous option. This sounds like a terrible UI, but for choosing the alarm sound or nature sound from a list of 5-to-10 options, it’s actually not so bad.
The FM radio is a disaster
For tuning the radio, it actually is so bad. The only good thing I can say about this clock’s FM radio is that it works…and even that’s a stretch.
This clock has digital radio tuning. Most alarm clocks with digital tuning show you the radio frequency on the screen. But the Galileo has no screen. So you might think the Galileo announces the radio frequency aloud, with its talking feature.
It doesn’t. So you have to tune the radio blind.
Basically, here’s my experience trying to tune the Galileo:
Turn the radio on.
Be blasted with an earful of DEAFENINGLY loud static.
Try to turn volume down in a panic.
Be stymied by the Galileo’s aforementioned terrible volume control that doesn’t go any lower.
Do the whole Bluetooth workaround thing to lower the volume level to a point that tuning the radio is even tolerable. (Most people probably never get this far in the process.)
Click through radio stations that all sound like garbled static, never knowing which station you’re on or if the station you’re looking for is higher or lower than your current station.
Experiment with the “automatic tuning” feature by holding the “modes” button down. (No one would know this feature even existed unless they read the instructions.)
Realize that not a single station the clock automatically finds is any more audible than the rest.
Try to turn off automatic tuning.
Fail to turn off automatic tuning because the instructions don’t tell you how.
Shut the entire clock off. (Aha! There’s a use for the on/off switch!)
Repeat.
I never managed to tune the Galileo to a station I could actually hear well enough to listen to. And while this was far from a formal test of radio reception, I will say that I have tried several alarm clocks in my bedroom that could tune in my local NPR station almost perfectly. Whether the Galileo couldn’t play NPR because it has bad reception or because I never found the NPR station while tuning blind, I don’t know!
The good news is, it barely even matters that the “prev/next” button makes it hard to tune to previous stations. Because if you never know what station you’re on, you never know if you need to tune backwards or forwards to get to where you’re going, so you relent and just tune forwards!
The best (and by best I mean worst) part of the Galileo’s FM radio experience is that, as previously noted, the FM radio is the first mode in the mode sequence. That means that every time you want to play Bluetooth, or change the alarm sound or nature sound, you have to click through the radio mode, and be greeted with DEAFENINGLY loud radio static that you can’t make quiet because of the terrible volume control. This is probably the single worst design flaw of this entire clock. You have to hear ear-splitting radio static every time you want to play Bluetooth, unless you play the thing like a rhythm game and click to the next mode fast enough to skip the static, but slow enough for the clock to actually respond.
One actually good thing: If by some miracle you get the radio to work, you can stop listening by pressing the play/pause button, without having to fully shut the clock off at the on/off switch or click through the entire mode sequence to get back to standby mode. Of course, then you have to wonder if you’re still in radio mode (just paused), or if you’ve exited fully to standby mode. Who knows. Unknowable things.
On the bright side…
The Bluetooth works! After you’ve been blasted by radio static, you can have a perfectly pleasant experience listening to your own music, at a low volume that you selected from your phone! The Bluetooth connectivity was reliable in the few times I tried it, and while I didn’t turn the volume up loud enough to really test the sound because MY EARS WERE STILL RINGING (/s), my songs did sound clear and crisp at low volume. So that’s good, I guess!
And Core Innovations did go all-out and provide an aux-in jack, in case you want to play the rare gadget that lacks Bluetooth capability. Aux-in sort of feels like the wrong thing for them to splurge on in the development process (as opposed to USER INTERFACE DESIGN), but what can you do?
One weird thing: I’m pretty sure this clock has stereo speakers. There are two speaker grilles on the back, and while many clocks have a fake second speaker grille, the instructions list the speakers as "2*3w" which I believe means there actually are two of them (at 3 watts apiece). This is also a weird thing for Core Innovations to splurge on, since there’s no actual stereo separation between the speakers. And yet, here we are!
The great nature sound trade-off
Don’t worry, y’all. There are still more idiosyncratic and arbitrary things to discover about the Galileo!
The Galileo includes 9 nature sounds to help you or a loved one fall asleep peacefully. The nature sounds seem fairly competent at a glance, although some are so similar that I couldn’t tell them apart.
The instruction manual notes that you can turn on the “sleep sounds” by pressing the button on the clock’s back panel. Or you can turn on the “snooze sounds” by pressing the snooze button. You can select the “snooze sound” within one of the clock's different modes, like I mentioned a few sections ago.
When I read the instructions before buying this clock, I wasn’t sure if there was a distinction between “sleep sounds” and “snooze sounds,” and if so, what that distinction was. Now I know, and…ugh.
When you press the snooze button to start nature sound playback, the clock plays whichever sound you previously selected. But you can’t set a playback timer. The sound plays indefinitely until you shut it off.
If you want to set a timer, you have to turn nature sound playback on using the button on the back panel. Repeatedly pressing this button toggles through the available timer options.
But when you turn nature sounds on using the back panel, you can’t choose which sound to listen to. The button on the back panel always turns on the same nature sound, which has various wildlife sounds (like birds chirping).
So basically, you get to play the fun trade-off of whether you want a timer for your nature sounds, or you want to pick a sound other than the wildlife sound. Because you can’t do both!
Is this clock any good?
This is a good time to remind you that I am not a product reviewer. I did not test this clock methodically, and I cannot speak to its durability over time. Though it seems to now be unavailable for sale anywhere (except used), so I guess my take on it doesn’t matter either way.
I think my take is that this clock, as fascinating as I find it, is not a good clock. I think the issue of deafening FM radio static makes this clock a frustrating radio or Bluetooth speaker. And I think the issues of poor clock face illumination and no obvious way to check the battery level make it an iffy alarm clock. At least it’s a fairly competent nature sound machine, despite the weird timer nonsense!
Core Innovations could have made this clock way better with just a few simple tweaks. I think a small display (even on the back) could show settings, radio frequency, battery level, and other information, which would vastly improve usability. The FM radio static issue could be eliminated by offering lower volume levels, and by allowing users to turn on features like Bluetooth without having to turn on the radio first. (Honestly, Core Innovations could drop the radio feature entirely if they wanted to, since so few people still use radios and so few alarm clocks still offer them.) I also think dimming the LED light (or offering a brightness setting) would make checking the time in the dark far more pleasant.
But despite its flaws, I am enormously grateful that the Core Innovations Galileo exists, because it just gave me 4,500 words of alarm clock blogging! By following precious few alarm clock conventions and charting its own (messy, idiosyncratic, endearing) path, this clock has won my heart and burned itself into my memory. Alarm clocks this bizarre are once-in-a-lifetime finds, so I will happily accept this gift from the universe. I hope you found this clock as entertaining as I find it!
