Because I wanted this life-size prop to match the dimensions of the original tiny toy, Josh made a 3d model of the LEGO piece and scaled it. You can also do this on paper by mathematically calculating the ratios and drawing out the shape. He measured the walkie talkie with some calipers and scaled the model to fit an adult hand.
Now that the shape of the full-sized toy was made, he used a plug-in for Fusion 360 made by Shaper to get a 2-d image of the faces. We printed out those templates on sticker paper and placed them on our material.
I know, I know, you made be asking, "why did you use a 3d model to make a paper template to cut things out by hand?" And the easiest answer to that is, because not everyone has access to 3d printers or CNC machines, and honestly, I think it is faster to cut the layers out of thinner wood. The model was scaled so that we could make this toy out of 3 layers of 1/4" MDF. I cut the blocky shapes with the bandsaw, but a jigsaw would work just fine.
The antenna was made from 3/4" scrap wood turned on the lathe to match the toy's profile. This could have also been done in the same sandwiching method as the rest of the body and rounded-over with a router bit. The larger LEGO studs were cut from 3/4" MDF using the drill press. I clamped the board down to the drill press table and first hogged out the middle with a 1-1/4" forstner bit. The outsides were cut using a 2-1/8" hole saw. All of these pieces were simply CA glued together and the face snapped on with some small, but strong, magnets.
To make the toy buttons actually work, I planned on adding some small microswitches inside the walkie talkie. To press them, I planned on using some squishy EVA foam that looked like the actual buttons. I punched out the circular buttons with a metal piece of scrap pipe, pressed into the foam. I simply cut a rectangular piece of foam for the larger paddle button.
In order to make this prop remotely control a Twitch stream, I had to add some electronics with Bluetooth capability. I used the Adafruit Feather microcontroller to act as a simulated keyboard that would send key commands wirelessly to the computer running our Twitch setup. There is a really simple code setup on our Github page if you are interested in recreating this on your own. Also
I soldered three separate small, tactile buttons onto the board as inputs and connected a small LiPo battery to power the whole thing. Using hot glue, I mounted the board, battery, and buttons inside of the painted Walkie Talkie and snapped the lip closed. I hot glued on the foam buttons and the Bluetooth life-sized LEGO Walkie Talkie Twitch stream controller was ready to test.
The basic concept for this controller is quite simple. I used a piece of software called OBS to capture video feeds from separate cameras set up in my shop. This software allows you to switch from camera to camera by using hotkeys. I can assign a random keyboard button to control individual cameras. So, if I were to press the letter A, then I can make a camera in the metal-working area the live image. This LEGO Walkie Talkie and its three buttons will send those keyboard commands to OBS instead of pressing the buttons on my keyboard.
During our weekly live shop build on Twitch, I assigned the hotkey commands to the three LEGO buttons and it almost worked. The small tactile buttons I soldered to the board weren't responding consistently, so I swapped them out with some larger microswitches. These new input switches worked much better and the toy remote was super responsive and switched the cameras around perfectly!

About I Like To Make Stuff:
We have lots of projects including woodworking, metalworking, electronics, 3D printing, prop making and more!
These videos are our attempt inspire and empower others to make the stuff that they want to have. Hopefully you'll see something here that will inspire you to make something that you're passionate about!
Buttons are always hard to figure out when you're doing electronics. I really like using mechanical keys from actual mechanical keyboards. You can pick up 50 switches for like £10 on eBay. They feel nice a lot nicer than the little clicky ones that come in most electronics kits, they are easy to surface mount and it's easy to find 3d printable models of keycaps which you can customize to look however you want.
I made some keycaps that had a space for Adafruit Neopixel chips inside them so they could light up depending on how you program whatever is controlling it. I used these in a console for my Blackmagic ATEM video switch so it showed the button for the live cam in red and the button for the cued up camera in green. Works great!
That's a really good tip, thanks!
This is awesome!
I hope people appreciate that the minfig in the thumbnail is an ORIGINAL spaceman with the actual broken helmet, not a "Benny." We go all out for thumbnails. FIRST!
The P.I. Workshop YES!
I have an organizer full of broken space helmets! All colors.
All of those minifigs are mine from the original sets. But thanks!
Definitely appreciated!!
On my phone it says you commented this 1 day ago.... you time traveling majestic wizard. I love you
Love it! The full scale LEGO building has begun!!!!!
Walkie-talkie is classic. The space gun/megaphone was a good one too.
Sorrrrrrry Bob! HAAAA! The walkie talkie was on my list, but now I don't have to make that. =D
Id like to see a build off competition. You each have to make the same lego part.
We know is not true Bill 😋😁
You can make LEGO style armor to go with your sword and helmet
Wow, thanks Bill!
OoOoOoOofff
As always great project! I worked with MDF a few weeks ago and found that flooding the “I end grain“ of the MDF with wood glue before painting, really help get a very uniform Appearance on the final result. Not necessary but just a quick tip for all you makers out there. Great project Bob,
That's a good tip, thanks!
I’m literally a twitch streamer who builds legos. This is awesome!!!
Never knew that existed but i will check you out!
Vid Rogic @ brickatecture
For me this is nostalgia. As a child I played with lego for hours and hours. It was a pleasure to watch this video!
Great, I still play with them for hours.
@@Iliketomakestuff Honest, me too! My children have lego and sometimes I play together with them. A man always remains a bit of a child hahahaha
Magnets are always the answer!! 🧲 🧙♂️
I Love your videos!
But how do they work?
Can magnets fix my parents failed marriage? :(
@@Bbistheman_ only flex tape can do that
Great way to turn a repetitious task into a fun project.
You know you’re a clamp champ when you clamp your clamps... that are already clamped to clamps
clamps 4 life bro
Hey, just wanted to say thanks to you and a few other woodworking UA-camrs for inspiring me to make a start on my own stuff. So last week I ordered some wood glue, some spreaders and a band clamp to help fix some chairs we bought that have come apart at the back joints. They were never glued originally so didn't last long, but they're nice chairs. Chair #2 is currently sitting all clamped up waiting for the glue to dry!
I really like the 3 direction / tool breakdown towards the beginning - detailing which tool you were going to use for which part. Something about the way that’s broken down really clicked for me. I think it’s a helpful way to think about a project whether one has the particular tools you are using or not. Cheers!
Awesome! My three favorite Maker things in one video: electronics, LEGO, and woodworking!
Where is the r2d2?
I love how you approached this using tools everyone will have. Great job Bob!
Thanks!
Yea bro because every body carries and table saw In their pocket
RumbleLab lathe? Table saw? Band saw? Belt sander?
What kind of people do you know? There are more people with 3D-printers than people with all of these power tools combined.
That is so cool. Magnets.... never thought about using them to hold stuff together. Thanks Bob
That's so cool, Bob! So trippy at the end where it is basically Bob-Ception.
I love these kinds of projects... Thanks, Bob!
This is sweet. I teach industrial technology, lead a Makers Club, and lead a video broadcasting group who uses OBS too. We’ve been looking for something just like this. Looks like I’ve just found the latest project for the makers club 👍. Thanks, Bob. It’ll be the second of your projects we complete. The first being the mini retro pie arcade, of course.
What a cool build. Makes me want to create some kind of remote just for fun!
More lathe action on the channel is always needed!
Man, dats a naice paint jaib, Baib
Wait...he clamped a clamp
You take risks when you're the clamp champ
that's how you champ the champ!
Clampception.
Don’t question it
clamps 4 life
*Thank you Bob, very cool!*
THE CLAMP CHAMP!!!!
Be sure to test the polarity of your magnets before gluing them in. This is the voice of experience from a tabletop wargame miniature hobbyist. If you forget once and aren't on the side of 50% lucky, you'll never forget this step again.
Just wish that I had these types of tools at home so my dad and I could work on some projects and spend time together. Love your videos and can't wait for the next one.
This whole project can be done with really simple tools.
great video Bob, I very rarely want to re-create the project that you are showing, but CANNOT miss anything you put out, very entertaining. PS i think that you do adds the right way during your videos and i think everyone should follow suit, talking head while showing simple tasks in the background is much easier to watch than totally breaking into an add. Keep it up!
Great build, Bob. I introduced my girlfriend to the channel over the weekend with this video. She was like "I never would have chosen this on my own but I love it!"
That came out very cool. Sweet paint jabe! Well done!
I remeber looking back at old videos looking at his clamps then compared to them now
You /could/ still make the Lego sword and add your own spin by embedding electronics like in this project. Maybe accelorometers to trigger sound effects when swinging?
You should both make a sword then have a meet up & dual it out. Put some electronics with sound in your sword to make it cooler than Bill's.
Bob is back with walkie talkie♥️♥️♥️😍😍
I died laughing at the clamp scene. I've always wanted one of these wood working channels to do that, and someone finally did it. I can die happy now.
Great job again! Thanks for staying away from the 3d printer and using wood and everyday tools. Love how you make it so that anyone can do it
This thing is awesome! This thing is better since it’s part of your team.
Honestly I was expecting a 3D printer project. But cool. I appreciate you doing it with "normal" tools.
Awsome, maybe make the stud pieces 2 speakers?
Cool idea
Everything is awesome! nice one Bob
My #ClampChamp
My son just asked to make one!!! No choice I need to make it!!! Good job Bob!!!
As much as I've been enjoying the renovation videos, it's definitely nice to get back to something a little more fun than functional. Great vid!
Agreed.
Love this! Awesome idea and project!
I'm From Czech and every time I see walkie talkie i start to laugh lol
great job slipping that sponsor in there, I sat through the whole thing for once watching the background
Great build! 👍🏼 full of tips to pick up and LEGO!! 😎👍🏼
Great project Bob! I noticed the Code Resources link for Adafruit in the description accidentally goes to an Amazon product. And thanks for helping me discover kit.com, which looks like a great resource. -Donald
Always innovative and to the point thanks alot for the great and enriching ideas bob.
I’ve been here since 2013 and I’ve never missed a video
Thanks for the support!
I Like To Make Stuff no problem also could I get a shoutout I’m really close to 100 subs and it would mean the world if I could get there
I love how you could have just taken your fusion model and just 3D printed the whole thing out and called it a day, but instead made this with tools and materials that most people have. This was fun to watch! Also it's always fun to see some electronics end up in your project! This is some very engaging content and I just had to share my reaction 😉. Keep up the great work man!
Thanks man 😀
This is awesome man!!! Love the functionality! I'm wanting to get into more prop and nostalgia stuff. Maybe old cereal box toys 🤔
If you don't have a band saw use your CNC.
Bob you should check out the elgato stream deck you can add pictures to see wich scene you want to press and it has i think 12 programmable buttons which helps switching scenes.
2:30 that clap champ though
Nice!! Can you make a Lego Spaceman Helmet? I bet Bill Durant won't think of that one lol. 😉
This video has given me a way to make my wireless fireworks igniter I’ve been wanting to make much cheaper and more custom thank you. Love your videos
I always wait for the Bloopers, it's awesome that you add them. Not only does it keeps your views going, but it shows you're human too LOL. Maybe a Bloopers/Outtakes only sometime?? Keep it up man!!!
A cool way to get more precise parts on a wood lathe (especially complex curves) is to cut out the negative of haof of the bluprint. Then you basically have template of the curve, you can hold up to the part the check how accurate you are
Put those heat shrinks on the crocodile clips!
Hai, I bet you can slide de two peces away. But one side with two small dowels and on the other side two holes would prevent that. Rob.
I like to make stuff and Mike Boyd were literally the two channels I first subscribed to! This felt weird :p You guys should do a crossover episode! Mike learns to make a closet and you learn a new skill and see how long it takes!
Love this! Sooooo many ideas now!
I need to make one of these.
You should make a huge lego hand to use as a dock for it
Love your channel. Keep on assembling.
Ya did a great paint jeorb there, Bob!
Great techniques Bob, particularly like the making of the rings
Nice one! I'll be ordering one of those boards!
Hella cool project Bob, nice job!
Great video as always :) one thought on the magnets, if possible, you could put half of the magnets in at half depth, and the other side in at 1.5 depth, then the magnet acts a little like a dowel to resist sliding which can be an issue when using magnets for closures like this, but they still touch keeping your box shut. Just thought of this while watching as i have had an issue with sliding in the past.
I believe you should make de "mini" figure.. I love the astronaut too
Thought for sure from the thumbnail it was 3D printed, nice work using MDF it fooled me!
Very Cool Sir.
12:53 so many layers.
Am I dyslexic or did anyone else read this as Lego Walkie Talkie Switch Controller and get mad excited
Does the handle magically change shape at 7:43 ?
Just ended up getting a lot more sanding until the inside was pretty much flat. Cut for time! ✂️
Thanks so much for this video. I’ve been trying to find a way to build a small hotkey remote for use with some art programs on iOS. I’m a relative beginner when it comes to electronics and I knew something like that was possible, but I didn’t really know where to start. The internals of your project are exactly what I needed and now I’m sure I can modify this to fit my purposes. Thanks again!
I was thinking about the foam being a different material and how to fix it. you could make a thin ring or "shell" for the foam buttons so that it looks a bit cleaner but still has the squishiness to it for when you press the button. Hope that helps :) Love the video and cannot wait to see what you make next :)
my favorite!
We need a challenge of you only using hand tools on a project!
Awesome job, dude! 😃
Thank you!
Looks awesome
*LEGOMAN LEFT THE GAME*
Very cool! You are so creative.
when you realized peter mckinnon intro was playing and you freak out! xD
Mannn this is a cute project!
I recently found out about black hot glue. If you wanted to have the charging port accessible I bet that would be a good way to fill the gap around it/hold it.
Good call!
Nice! Great vid Bob 🙂
The fact that the handle isn’t accurate pisses me off more then it should 😂😂 this is great tho I’m just petty about legos 😂
You should ask bill to mold and cast his sword.
Would love to see the CNC in action. Norm Abram never apologized for the tools he had!
Norm also didn’t ha e to read the comments under his shows 😉
This is awesome
da clamp champ is back!
Hey Bob, I totally enjoyed this build... but I have to say the music was really good! You always have awesome music playing in the background of your videos... unlike others. But what I’m mostly curious about is what type of music are you into? Like top 5 Bob’s I like to make stuff music playlist??!🤔😆 later dood ✊🏼
Excellent stuff, as always! But the antenna seems a weak spot prone to snapping away. I'd probably pin it with a dowel.
Really cool! 👍🏻👊🏻
Hey, Bob.
I would have added wireless charging! And make the inside neat.
