But i thought i’d share it. Let you guys maybe see what it cost to build one of these things. So let me uh shrink my little picture down here and get more interesting things up to my my face. Come on got it so here’s my spreadsheet and, as you can see across the top here, i um i named the columns right. Of course you have to know what the part is quantity of that i bought. Now the quantity is the packages. If you look in the part, sometimes it’ll explain to you that you know there’s 50 in a bag or whatever, like that. So when you’re looking at the quantity, you have to look at the part description in the in the quantity, column, kind of combine the two unit price and then the total price. Okay, because if i you know if i bought more than one of course, it’s gon na double the price right, shipping taxes and the total per item, but i just wanted to break that out. I was curious. You know, because you see a total cost and you say: well: i’m. I’M uh. I paid this much for it, but in reality you paid a little less, but you would charge for shipping and you would charge taxes and i thought it would be kind of nice to know how much of what i actually spent that money on and then the Last column here i i highlight for you is the store i bought it at okay.

Of course, this stuff was bought. You know shipped to me and so you’ll see that most of it was from aliexpress or bought from ebay, but there are a couple items in there that are specialty items you know bought from the uh the store. So let me go down to the bottom of the college here: i’m, not going to bother to to go down to each one of these parts that i bought the bill of material i’ll show you i’ll show you how i base this here in a minute anyway. So going all the way down to the bottom. I tally up my my columns here. You can see my total price is 1. 929 shipping was 169. taxes, 126 dollars for a grand total of 2 25. Now i i had a luxury that i was lucky to have and that i had to model trains, and so i went on ebay and i sold all my model trade stuff and collected that cash. And so, since i had the pocket of cash, i ordered the bulk of my bill of materials. At the same time, my thinking was then i don’t have to wait for anything, and you know i don’t pay as much in the shipping. If i could do it. Some of that combined shipping to keep that cost down, so that that was my goal, and i was a little bit surprised that this was a little higher than i thought it would be, but those servos they cost a little bit of money so that they were Probably the they were, the most expensive things other than the little mini pc.

They were by far the the most expensive things and, as i as i use some of this stuff, i’ll i’ll explain why i chose this pc or or this video screen so i’m not going to go into those details now. But how did i come up with this build material? I went to the in move website. Okay, you can see it up. There highlight it for you, that’s the that’s, the main page for in move for the whole shooting the whole mess. Okay, just go here and you can find all the different forms and get togethers. So i went under build yours and there you have hardware map and bill of materials. This is where i started. So it starts off first by mapping the hardware for you you’ll get more of this, as as we build a robot, but this is really the i o assignment um. What was connected to what pin on the arduinos and so forth. So it gives you the the spreadsheet layout and then it gives you kind of a basic schematic of of what he did there, and this is the opposite side, a basic uh layout of the test diagram here, how he was testing things. Let me pop that up a little bit bigger how he was testing things and he used the six volt batteries there that you know for servo power and he used the arduino mega for the control i’ll. Be using that shortly that this configuration to test my finger.

I almost have everything i need to do that finger so that’ll be coming up pretty quick. Then it gives you a kind of a basic pictorial overview of the hardware. You know left side right side. All this is available to you on his site. You can download a copy of it and then it gets into the bill material, and you see here the last time he updated. This was 2016, so it’s getting a little age on it, but it goes down through here and he tells you okay here here. I use these countersunk screw screw heads right and it gives you the uh the dimension and about how many of you used. So this began to form my bill of material and he goes into the uh hand in the forearm left and right. So i i went through this and i i tallied up all all the servos, all the nuts and the bolts and everything – and i came up with with the total number of parts needed that’s. How i accomplish that so i’m not going to spend a whole lot of time going through here. You can of course, call this site up. You can look at his bill of materials. You can study my spreadsheet. I hope my spreadsheet gives you a more consolidated idea of what you’re looking at and what to buy. It goes to the the what type of speaker he bought and how he hooked it up to his audio amplifier.

Then he goes into the stubborn, the ribbon cable lights. This is nice to know these. These approximations i wouldn’t, as he says in his videos. You wouldn’t set these in concrete, but they’re good guidelines to kind of let you know how much you need to buy now. One thing i i didn’t do i didn’t buy this ribbon cable. You won’t see that on my bill of material – and i i held off on that until i got the the connectors because in his explanations he’s showing the pitch that ribbon cable is uh. Two point: uh of the connectors is 2.54 for the pitch. Then he gives you a link to where he bought the ribbon cable from, but when it pops up it’s it’s popping up to a 1.27 millimeter pitch so i’m, pretty sure it’s a 2.54. But i just held off on it since i live in the big town of houston, i can rent up to my uh electronic parts store and buy my ribbon cable locally, so i’ll save on the shipping and i’ll be sure to get the right right style on That, too, goes to the latest configuration of the nook right connected devices. What what’s connected to mrl, okay, that’s, my robot lab that’s, the software that used for the development and control of the robot. So what he’s saying is all these things plug into the computer and run through the the software? So this is what he saw is everything that that was in there.

Some people have added more. Some people left things out: it’s it’s a hodgepodge, but what do you want your robot to do, but this is how he’s developed his older configurations uh this. I wish he would actually remove. I found this more confusing than helpful since um nobody’s doing this since he’s. Not even recommending it anymore personally, i i think it would be better to remove it. Uh power pack – okay, this is just uh it’s like a battery pack. Okay use it for remote powering. You see it used a lot for recharging cell phones and things like that. Substitute possible tablets – and it might have been helpful to some – i would have taken it off the bill of material and put it on a separate. You know maybe just a link to it, here’s, something that i thought was interesting, something that might be worth to point out. His connect is being powered off a battery pack. Now, if you notice the battery pack holds 10 batteries, not eight standard non rechargeable batteries are 1.5 volt. So, to get 12 volts, you don’t need 10., but if you’re using rechargeable cells, they’re 1.2 volts not 1.5, so you do need 10 of those to get you to your 12 volts. So just something to point out why this was done on things he’s abandoned again. I would have put this on on just a link his you know, past history type thing, severals of pr that he used in his preferences alternatives.

Then it goes back into the bicep, shoulder and torso, okay in the eyes and the stomach, and we drop down to people leaving their comments now he’s in france he’s a frenchman. He did this website in french and i had uh google translate it to english. For me, so when you get down to the comments, you start seeing things coming up in french, they can be translated his funny. His responses are in english, but so that pretty much covers what was uh in the bill of material that he provided. I went a little bit deeper and, as i was studying and watching some of the the videos and and the tutorials on how to build these different components he would mention you know. I used this many screws here or there or different things like that, and – and i captured some of that in my build material – to help me get a better number, so that’s that’s, basically what this uh this one’s all about. This video is all about, but i i just thought i’d. Also let you see what uh my blog looks like if you call it up and and look at the silly thing right this this one will always be on the top. This is kind of my introduction. Uh calibration is one that i i just recently did to show you how i calibrated my my printer and then, of course, the next time you look at this there’ll be one on here for my bill of material which i’m making for you now now there’s video Links on on this page that are actually on youtube, so you can follow me two ways you can either go to youtube.

Follow me there or you can follow the blog. Now i may be putting stuff here on the blog, and you know in written text that you might might not get to see on youtube i’m going to evaluate this combination and make up my mind. Is there enough distinction here to to keep both going? You know i’ll probably have to keep the youtube going. If i keep the blog going because the size of these videos, i can’t upload them to the blog directly. So i put a link to youtube, but if, if i don’t see enough activity or use in in the blog, i may just end this and just continue to use youtube directly that’s a determination i’ll make as as i go through this process. So hang in there check them both out. You can see up here. This is the the link to my uh, my blog, if you type that in you’ll come up to this page.
