Today, I'm going to teach you how to build a working, life-sized, phone-controlled Starwars BB-8 droid! In this tutorial, we are only going to use household materials and a little Arduino circuitry.

`

My Christmas Gift For Dad: One of my dad's hobby is being a toy collector (Hot Toys, Enterbay & Etc..). He grew up watching movies from the 80's, including Starwars! He is a really huge Starwars fan. When the Sphero BB8 was announced, he wanted it so badly! The Sphero toy cost $150 online, $210 in our country (Philippines), not to mention that they ran out of stock easily! It's not the typical toy that you would buy impulsively. Knowing with my past experience in building robots, I figured I could build a life-sized version of the Sphero BB8 for less than $100. I also saw this as an opportunity to spend some father-and-son time with him. This is what we ended up building in the week of Christmas! Anyway, my mom and I also got him a Sphero BB8 and used it as our reference for building this project. For him I guess, the best gift was the time we spent building it together.

`

Why Household Materials?

Due to the limitation of materials, I resorted in using the materials around me. (deodorant roll-ons as ball bearings, canvas as fiberglass, Christmas balls as the eye & etc.. ). A lot of people could relate to this. My approach on building the project doesn't require 3D printers, CNCs or Milling Machines!

Step to be written soon!

please tell us how to connect mp3 module to Arduino Uno (connection) and code<br><br>and I use L293d motor shield so what changes should I do in this bb8 code
Hey, please could yo send the dimentions of the various wood components and artwork.<br><br>I am thinking of getting this 3d printed so any othe spec documents woud help<br>
<p>steven.jowell@gmail.com</p>
Can you send me the pdf file pleasethank you martin_tanya_ivanovi@yahoo.com
<p>hello, anyone can send me pictures of how you wire the electronics?<br>my email is vanessa.axl@hotmail.it</p>
<p>Greetings, I'm making this project and I have a couple of doubts, on step 27 you show a wooden disk, I'd like to know the size of it, and on step 36 there are some wooden supports shown on the photos, I'd like to ask for their sizes, thanks in advance</p>
Hi dude I can't able to download the arduino files .......where can I find that
Im afraid it might crack when I cut it. Has it cracked for anybody? I used a beach ball, newspaper, canvas, and wood filler. Do you guys think it will crack
<p>help please</p>
<p>P.S. I made the whole thing and will post pictures. I made my own program and templates and design. Just need to put the batteries together and I'm done.</p>
<p>Hello, I was wondering what kind of wires should I buy for this build? I only need wires for the motor (i have the same one as in the video) and some from the bluetooth module to the arduino.</p>
<p>Just use 20 AWG to 22 AWG hook up wire. just as any other electronics project ; )</p>
<p>Alright, thanks for the help!</p>
<p>Hi, I'm building this too and was wondering if you had the design templates or the wood measurements? If so, it would be great if you could send them my way! gretchentw517@yahoo.com</p>
<p>Can you please send me the wood measurements and the design for the bb-8 my email is sphhobbie0@gmail.com thanks!</p>
<p>Could you email the pdf files to therealbb87@gmail.com? Thanks!</p>
<p>could u send me the PDF of the templates please </p>
<p>You have to use android. You can buy a cheap tablet. The app takes hardly any storage.</p>
Surely there's a Bluetooth app for the iPad that ppl could use if they didn't have Android.
<p>can you explain it to me too? The measurement on the wood cut </p>
<p>by any chance do you know the dimension on the wood cut outs? </p>
<p>hey thanks</p>
<p>I made it. Here are the images: It cost me over 1000 USD and I'm 13.</p>
Thanks so much! I'm in the same situation as you. I wish this guy would fix the instructions so they made some more sense.
<p>I know. It was very challenging.. Good luck to anyone building this, and may the force be with you ;)</p>
<p>Hey, could you tell me what wires i should get? Also, could you email me the PDF (mail4brando@gmail.com)? Sorry about all the help i need(i'm a noob lol), but could you also help me out with the broken arduino code? Is there an easy way i could fix it?</p>
<p>Use jumper wires. They are cheap and easy.</p>
<p>Ok, thanks for the tip :)</p>
What did you do for wheels. I can't seem to find any online.
Tamiya 70111 Large Diameter Wheel Set
<p>Hi,</p><p>I resorted to the Pololu wheels after buying the hubs that were compatible with the motors. I bought them off amazon, but you can buy them on Pololu's website.</p>
Hey, thanks for all of your help. Is it possible that I could have a link to where you found these wheels. I am having very little luck.
Hey arnav<br>Please tell me how did you make a switch and the charging ports
<p>Here is the inside, the templates and the finished ball.</p>
Hey, I have heard that there is an error in the code for the arduino. Is this true, and if it is, how do you fix it?
<p>What made it cost so much?</p>
<p><a href="https://docs.google.com/spreadsheets/d/1X1660RH9u0zMqX6ZIQGvnTYxJhE51bQaxhcSPcqM8zY/edit?usp=sharing" rel="nofollow">Here is the expense sheet.</a></p>
<p>Wow 188 for the battery? there are much cheaper options out there</p>
<p>The batteries were used to power a 12v amplifier because the sound wouldn't carry through the fiberglass.</p>
For future projects, look into rc lipos. You can get the same capacity for less money and they'll be lighter
<p>Thanks for the breakdown - I find the China sites great for supplies like these at a fraction of the cost of the more usual shops, (at the expense of 3 to 4 week postage times) - this is a good site and would have most of the electrical, painting and magnet items on your expense sheet.</p><p><a href="http://www.banggood.com/">http://www.banggood.com/</a> </p><p>There are even cheaper sites (like aliexpress) - but I prefer the above as its just the one seller you are dealing with.</p>
<p>banggood is a good alternative to amazon and pololu.</p>
<p>i'm frm INDIA......I'm an able find Motor Shield and Metal Gearbox-.......can i get other way to build it???</p>
<p>Arnavk do you have the pdf file for BB-8s artwork?</p>
<p>I free handed it. </p>
<p>Yes. Adafruit is a great alternative. You can also use Arduino's Motor shields and compatible motors.</p>
<p>thanks for your advice :).</p>
<p>No Problem</p>
<p>are any of these motor shields compatible with raspberry pi</p>
<p>A raspberry pi is a computer. I would suggest digging into that. Good Luck :)</p>
