First attempts involved heating in a microwave or chilling the cookies in the freezer. Neither helped in the slightest. A vacuum chamber only served to delaminate the cream from both sides of the cookie entirely, while water jet cutting made an awful mess.
[Ian] ended up realizing that crack propagation could be used to prepare Oreos for a perfect split. A knife was used to score a groove all around the cream layer, right down the middle. The Oreos were then frozen, turning the cream effectively solid. When the Oreo is then twisted, the groove serves as a starting point for a crack that propagates across the surface, splitting the cream neatly between both halves.
[Ian] took things further by building a 3D-printed lathe that grooves Oreos using a sterilized scalpel blade. This allows cookies to be quickly prepped for a perfect split. However, you are left eating frozen Oreos at the end of it, with some sacrifices to freshness.
It’s a neat way to approach the Oreo splitting problem, even if it’s only one step removed from simply using a knife. We’ve seen [Ian]’s work before, too, in the form of the radioactively-powered Game Boy. Video after the break.
Wait, what? Is it possible that a tech company just killed off a product with a huge installed base of hardware and a community of dedicated users, and it wasn’t Google? Apparently not, if the stories of the sudden demise of Insteon are to be believed. The cloud-based home automation concern seems to have just disappeared — users report the service went offline at the end of last week, and hasn’t been back since. What’s more, the company’s executives removed Insteon from their LinkedIn profiles, and the CEO himself went so far as to remove his entire page from LinkedIn. The reasons behind the sudden disappearance remained a mystery until today, when The Register reported that Smartlabs, Inc., the parent company of Insteon, had become financially insolvent after an expected sale of the company failed in March. The fact that the company apparently knew this was going to happen weeks ago and never bothered to give the community a heads up before pulling the switches has led to a lot of hard feelings among the estimated 100,000 Insteonhub users.
Then again, with a comet the size of Rhode Island heading our way, a bunch of bricked smart bulbs might just be a moot point. The comet, known as C/2014 UN271, has a nucleus that is far larger than any previously discovered comet, which makes it a bit of an oddball and an exciting object to study. For those not familiar with the United States, Rhode Island is said to be a state wedged between Connecticut and Massachusetts, but even having lived in both those states, we couldn’t vouch for that. For scale, it’s about 80 miles (128 km) across, or a little bit bigger than Luxembourg, which we’re pretty sure is mythical, too. The comet is a couple of billion miles away at this point; it may never get closer than a billion miles from the Sun, and that in 2031. But given the way things have been going these last few years, we’re not banking on anything.
From the “Answering the Important Questions” file, news this week of the Massachusetts Institute of Technology’s breakthrough development of the “Oreometer,” a device to characterize the physical properties of Oreo cookies. The 3D printed device is capable of clamping onto the wafer parts of the popular sandwich cookie while applying axial torque. The yield strength of the tasty goop gluing the two wafers together can be analyzed, with particular emphasis on elucidating why it always seems to stay primarily on one wafer. Thoughtfully, the MIT folks made the Oreometer models available to one and all, so you can print one up and start your own line of cookie-related research. As a starting point, maybe take a look at the shear strength of the different flavors of Oreo, which might answer why the world needs Carrot Cake Oreos.
And finally, since we mentioned the word “skiving” last week in this space, it seems like the all-knowing algorithm has taken it upon itself to throw this fascinating look at bookbinding into our feed. We’re not complaining, mind you; the look inside Dublin’s J.E. Newman and Sons bookbinding shop, circa 1981, was worth every second of the 23-minute video. Absolutely everything was done by hand back then, and we’d imagine that very little has changed in the shop over the ensuing decades. The detail work is incredible, especially considering that very few jigs or fixtures are used to ensure that everything lines up. By the way, “skiving” in this case refers to the process of thinning out leather using a razor-sharp knife held on a bias to the material. It’s similar to the just-as-fascinating process used to make heat sinks that we happened upon last week.
A while back, [Emiel] aka [The Practical Engineer] created a hands-free Oreo dispenser for his shop. This was a necessary addition to his fleet of handy tools, and allowed him to multitask much more effectively by using a sander, for example, at the same time that he needed to eat a cookie. Of course, this time-saving device was missing one crucial element: milk. [Emiel] is back in this video to show off his milk-dispensing upgrade to his original Oreo dispenser.
A few ideas were considered before [Emiel] decided to build a separate unit for the milk dispenser, so as not to create a gigantic mess any time an Oreo was delivered, and also to maintain some decorum in the shop. He rebuilt the Oreo dispenser with a 3D printer and then also 3D printed the milk dispenser. The chin-activated switch inside the device turns on a small pump which squirts milk into the user’s mouth, presumably after an Oreo has been delivered.
There are a few problems with the build, but most are easily solved by replacing non-food-grade parts with plastic that is more safe for being around consumables. The only other thing we can see here is that it might be a little hard to keep things clean, both inside and out, but most Oreo-related builds like this one have at least some problem with cleanliness that isn’t impossible to keep up with.
Here’s a portable, well-built Oreo separator that still manages to border on ridiculous. Instead of just ditching the creme filling, it dispenses the cookie and the creme separately. Ostensibly the two creators like different things. One enjoys the cookies while the other only likes the creme. Of this division was born the professional-looking snack divider.
Unlike the hatchet-based system shown off in the first episode this machine has a hopper into which several Oreos may be loaded. The demo cookie is like none we’ve seen before because the top portion is pushed off as if it took no effort at all. The creme is then softened with a stream of hot air before the gooey creme is blasted into the other creators face. Some of it may even have entered his mouth. The final step ejects the remaining chocolate cookie by launching it straight up into the air.
Our favorite part of the video after the break is the “DO NOT ATTEMPT” subtitle that flashes on the screen whenever the apparatus is launching food into the guys’ mouths.
Look, we understand the need to find a project to occupy your time and interest. So we’re not going to ask the wrong question (why?) for this one. This guy hates the creme that connects the chocolate cookies to make an Oreo. So he built a complicated system to separate the cookies and remove the creme. Check out the video after the break for a hardware overview (where we catch a glimpse of an Arduino RBBB) and a complete demonstration.
Although the project is a marketing gimmick for the company, we really love the fun they had making the video and the device actually works! Drop a cookie in the chute and it will be lifted into position for cleaving with a hatchet (we’re unsure what the string mechanism on the hatchet is for). The two pieces are then grabbed by some servo-powered grippers and transferred to a CNC router bed where a Dremel tool removes the residual creme before dumping the cookies out into your hand.
Once again, marketers should take note of this style of advertising. Notice the two main features achieved here: including a product in something we’re genuinely interested in and not being annoying (we’re looking at you Head-On).
