Hey everybody, it's Adam from Tested and we have a really cool unboxing today. It is in this box and oh, it makes me so excited. But before I crack this, show you what's inside. We're going to do a little bit of history. See, humans have always been interested in numbers and quantifying their surroundings. It's one of the ways in which we further understand the universe. And we have invented some very clever methods for doing it. In the beginning, of course, humans use things like an abacus, abacus, abacus, an abacus, this. They use things like this to do some fairly sophisticated calculations. Later on, of course, we move to things like the slide rule. This very make and model is similar to what the scientist for the Apollo program used to get us to the moon. And of course, we're all familiar with digital calculators. But this is a special digital calculator because it was the first mass market produced hand held digital calculator. And what Texas instruments did with this was not only bring about a sea change in computation for the masses, but they also killed. They killed dead, but may have been the most advanced mechanical calculator ever released to the public. And that's where this story begins. This is one of my favorite devices in all of the world. And it's called a curta computer invented by Kurt Herstuck. While imprisoned in a concentration camp in World War II, I'm serious, he came up with the idea for this calculator in the concentration camp and when the war ended, he went and built a few hundred thousand of these over several decades. This is a type one curta computer. It is a completely mechanical. You set according to this register, the numbers that you want to add, subtract, multiply and divide. And then you turn this little crank, the crank was the reason it was affectionately known as the coffee grinder calculator. And the results come up here on top. Now this is a type one and this is a type two. I am proud to own a pair of these in my collection because mechanically, they're masterpieces. There's over 600 pieces in this little baby. And that's where the unboxing happens. See, what's in here is a very special curta computer. About a year and a half ago or so, I became aware that there was this guy online, a Marcus Wu, who had endeavored to make his own curta on a 3D printer. Because the resolution of a 3D printer is fairly low, he was making it large scale, a giant, oversized curta computer. I think it's 3x sized. And I asked if I could purchase one from him and we worked out a deal and in this box right here is a 3x normal sized 3D printed curta computer from Marcus. Ah, can you imagine? Well, you don't have to imagine because we're going to open it right now. What did he do? Oh my God, there's a box. Ah, Marcus is clearly an obsessive and amazing crafts person for even endeavouring to make a curta computer, but low. He has, look at this. I don't even know which way to, oh, I guess this is how, right, okay. He's made an absolutely gorgeous doweled wooden box with a label here that says curta in the original logo of the curta computer. I'm, I'm feeling a little emotional right about now. Okay, here we go. Nice brass hardware. Oh. Oh, there's a lot of it. That's open all out. Now we actually have footage of Marcus assembling building this curta computer for me and that will be part of this video because it's an insane endeavour to put one of these together. There are so many tiny little parts, even at 3x scale, I'm certain there are some parts of surpassing tinyness and precision required. Not further ado, let us see what Marcus has. Oh my gosh, look at this. Holy cow. Oh, man. Oh, man. Marcus, you are a mad man. Look at the finish on this thing. Holy. I'm having trouble not using expletives. I'm so excited. Maybe you just blur my mouth for a second. Holy. There we go. You know roughly what I said. Look at this thing. It is, he's replicated a three time, sorry. I was just about to tell you some facts about it, but then I looked at the bottom and so on the bottom of a curta computer, this is what it says. Made in licked in shine, et cetera, et cetera, et cetera, et cetera. Here's what Marcus has put on the bottom of his. So full disclosure, Marcus came out while I was out on tour this spring and we spent an evening going over one of the rough interim builds of this and I saw it and it was magnificent then, but it doesn't even hold a candle to what this is. The finish is just as beautiful as it looks upon the first glance here. It's so pretty. Oh my God. Okay. So I want to run it through some paces here. Let's see. First there's, right there's that. That's the zeroing knob. The registers set just like on a normal computer. That is a long helical gear. Oh man, look at that. Okay. So if we take let's say 55, 550 and we turn the dial once, functions just like the real thing. Number 55 comes up here. Wow. And then if I want to erase that, watch this. Ready? You can take a look at all these. Isn't that crazy? I'm so terrified of breaking any part of this by moving it, but it's so beautiful. You know how much I love objects. This is a truly magnificent object. And Marcus, I applaud your insanity, your dedication, your perseverance and your actual building and finishing techniques. This is truly magnificent. And I am so honored to add it to my collection. Thank you.
