Reverse Engineering Ahmed Mohamed’s Clock…
From: blogs.artvoice.com, by Anthony, on Sep 17, 2015, see the article HERE.
It’s hard not to conclude with some questions: Why did Ahmed pass off some old commercial clock innards as his creation? Why’d he package them in that case and not something more benign? And why was he so reluctant to be forthcoming with police about his motives? Why was his sister supplying him with answers to questions? Did his dad have some influence in this?
I have something in common with Ahmed Mohamed: as a youngster, I was also an electronics enthusiast. At his age and even earlier, I frequently took apart electronic devices – anything from my own toys, to broken things around the house, and even that dirty garbage-picked black and white TV my parents dragged home that they knew I’d have a blast playing with (I did.) I’d try and troubleshoot, repair, or sometimes just disassemble things and salvage components for future projects. I’d try and imagine how all those bits and pieces, lengths of wires, mazes of conductive circuit board traces all came together to produce an image, or a sound, or some other useful function. I wanted to know how it all worked.
Without dating myself – fast forward a bunch of years, and I’m the same way. I’ve even picked up an engineering degree over the course of those years. I don’t have to only imagine how things work anymore, I have a pretty good understanding now. When shopping for electronic devices, my first instinct is to see if there’s a way to build one myself (and, I frequently do!) When something of mine breaks, I don’t send it back, I take it as a personal challenge to get it working again. If I fail, I still salvage useful parts – they might come in handy to fix something else later. This aspect of myself – being both methodical, and curious – hasn’t changed a bit over the years.
I found the highest resolution photograph of the clock I could. Instantly, I was disappointed. Somewhere in all of this – there has indeed been a hoax. Ahmed Mohamed didn’t invent his own alarm clock. He didn’t even build a clock. Now, before I go on and get accused of attacking a 14 year old kid who’s already been through enough, let me explain my purpose. I don’t want to just dissect the clock. I want to dissect our reaction as a society to the situation. Part of that is the knee-jerk responses we’re all so quick to make without facts. So, before you scroll down and leave me angry comments, please continue to the end (or not – prove my point, and miss the point, entirely!)So, this story about a 14 year old boy in Texas that was arrested on suspicion of creating a bomb hoax (who, apparently just wanted to show off his latest electronics project to his teachers) that has blown up (no pun intended) all over the news and social media, caught my attention immediately. Not because of his race, or his religion, the seeming absurdity of the situation, the emotionally charged photo of a young boy in a NASA t-shirt being led off in hand cuffs, the hash tags, the presidential response… no, none of that. I’m an electronics geek. I was interested in the clock! I wanted to figure out what he had come up with.
For starters, one glance at the printed circuit board in the photo, and I knew we were looking at mid-to-late 1970s vintage electronics. Surely you’ve seen a modern circuit board, with metallic traces leading all over to the various components like an electronic spider’s web. You’ll notice right away the highly accurate spacing, straightness of the lines, consistency of the patterns. That’s because we design things on computers nowadays, and computers assist in routing these lines. Take a look at the board in Ahmed’s clock. It almost looks hand-drawn, right? That’s because it probably was. Computer aided design was in its infancy in the 70s. This is how simple, low cost items (like an alarm clock) were designed. Today, even a budding beginner is going to get some computer aided assistance – in fact they’ll probably start there, learning by simulating designs before building them. You can even simulate or lay out a board with free apps on your phone or tablet. A modern hobbyist usually wouldn’t be bothered with the outdated design techniques. There’s also silk screening on the board. An “M” logo, “C-94” (probably, a part number – C might even stand for “clock”), and what looks like an American flag. More about that in a minute. Point for now being, a hobbyist wouldn’t silk screen logos and part numbers on their home made creation. It’s pretty safe to say already we’re looking at ’70s tech, mass produced in a factory.
So I turned to eBay, searching for vintage alarm clocks. It only took a minute to locate Ahmed’s clock. See this eBay listing, up at the time of this writing. Amhed’s clock was invented, and built, by Micronta, a Radio Shack subsidary. Catalog number 63 756.
The shape and design is a dead give away. The large screen. The buttons on the front laid out horizontally would have been on a separate board – a large snooze button, four control buttons, and two switches to turn the alarm on and off, and choose two brightness levels. A second board inside would have contained the actual “brains” of the unit. The clock features a 9v battery back-up, and a switch on the rear allows the owner to choose between 12 and 24 hour time. (Features like a battery back-up, and a 24 hour time selection seems awful superfluous for a hobby project, don’t you think?) Oh, and about that “M” logo on the circuit board mentioned above? Micronta.
For one last bit of confirmation, I located the pencil box Ahmed used for his project. During this video interview he again claims it was his “invention” and that he “made” the device – but the important thing at the moment, at 1:13, we see him showing the pencil box on his computer screen. Here it is on Amazon, where it’s clearly labeled as being 8.25 inches wide. Our eBay seller also conveniently took a photo of the clock next to a ruler to show it’s scale – about 8 inches wide. The dimensions all line up perfectly.
So there you have it folks, Ahmed Mohamad did not invent, nor build a clock. He took apart an existing clock, and transplanted the guts into a pencil box, and claimed it was his own creation. It all seems really fishy to me.
If we accept the story about “inventing” an alarm clock is made up, as I think I’ve made a pretty good case for, it’s fair to wonder what other parts of the story might be made up, not reported factually by the media, or at least, exaggerated.
I refer back again to this YouTube video interview with Ahmed. He explains that he closed up the box with a piece of cord because he didn’t want it to look suspicious. I’m curious, why would “looking suspicious” have even crossed his mind before this whole event unfolded, if he was truly showing off a hobby project, something so innocuous as an alarm clock. Why did he choose a pencil box, one that looks like a miniature briefcase no less, as an enclosure for a clock? It’s awful hard to see the clock with the case closed. On the other hand, with the case open, it’s awful dangerous to have an exposed power transformer sitting near the snooze button (unless, perhaps his invention was to stop serial-snooze-button pressers by giving them a dangerous electrical shock!)
So again, I’m pointing all this out – about the specifics of the clock – not to pick on the poor kid. I’m picking on us, our culture, and our media. I don’t even care about the clock itself at this point.
If we stop and think – was it really such a ridiculous reaction from the teacher and the police in the first place? How many school shootings and incidents of violence have we had, where we hear afterwards “this could have been prevented, if only we paid more attention to the signs!” Teachers are taught to be suspicious and vigilant. Ahmed wasn’t accused of making a bomb – he was accused of making a look-alike, a hoax. And be honest with yourself, a big red digital display with a bunch of loose wires in a brief-case looking box is awful like a Hollywood-style representation of a bomb. Everyone jumped to play the race and religion cards and try and paint the teachers and police as idiots and bigots, but in my mind, they were probably acting responsibly and erring on the side of caution to protect the rest of their students, just in case. “This wouldn’t have happened if Ahmed were white,” they say. We’re supposed to be sensitive to school violence, but apparently religious and racial sensitivity trumps that. At least we have another clue about how the sensitivity and moral outrage pecking order lies.
Because, is it possible, that maybe, just maybe, this was actually a hoax bomb? A silly prank that was taken the wrong way? That the media then ran with, and everyone else got carried away? Maybe there wasn’t even any racial or religious bias on the parts of the teachers and police.
I don’t know any of these things. But I’m intellectually mature enough to admit I don’t know, and to also be OK with that. I don’t feel a need to take the first exist to conclusionville. But I do like to find facts where I can, and prefer to let them lead me to conclusions, rather than a knee jerk judgement based on a headline or sound bite.
I think the whole event – and our collective response, with everybody up to the President chiming in, says a whole lot about us. We don’t care that none of us were there and knows what happened, we jump to conclusions and assume we’re experts. We care about the story, but we don’t care about the actual facts. Headlines and click-bait are far more interesting than thinking for ourselves. We like to point out other any bit of perceived injustice or discrimination we can find – it’s practically a new national past-time. We like playing victim, and we like talking about victims – so much so we sometimes find victims where none really existed. We also like to find somebody to blame, even when there’s nobody at fault. We like to play social justice warrior on our Facebooks and Twitters, posting memes and headlines without digging in behind the sensationalism, winning bonus sensitivity points in the forms of likes and re-tweets. Once group-think kicks in, we rally around hash tags and start shouting moral outrage in a deafeningly loud national chorus. The media plays us like a fiddle, and we don’t even notice we’ve all been had.
As for me, I’m glad to apply the lessons I’ve learned as an electronics enthusiast to other aspects of life. There’s no emotion in troubleshooting a circuit, electricity doesn’t have morals. There’s just physics, and logic, and methodology. I think we could all benefit from applying a little more of that sort of thinking to these situations.
* Correction: A reader and commenter, Joe Donaldson, tracked down the clock in a Radio Shack catalog dated 1986. It’s likely that my guess of mid-to-late 70s was off by a bit, and it’s now obvious it was a model that was for sale in the mid 80s. Though it doesn’t really change the point, I want to post this correction here for accuracy sake and thank Joe for the heads up. (See the comment here, with link to the catalog page.)
