Awesome project, Bob and I would love see you make a Giant Operation Game just like the kids board game. Now that would be awesome project to watch and fun to play with too.

“Gentlemen, we will chase perfection, and we will chase it relentlessly, knowing all the while we can never attain it. But along the way, we shall catch excellence.” ― Vince Lombardi Today, Bob, you caught Excellence, and that's ok! I like the struggles and you keeping them in there to show the how/why of your attempt to work around them. This is very true in almost everything we make, and it a great piece of the puzzle that I attempt to explain to my kids. It turned out amazing! Excellent!
Wow... this video is Perfection 😋 but seriously love all the different types of making that are in the video... electronics, woodworking, 3D modeling, 3D printing, CNC, even some foam!
You should write hidden messages and drawings on your whiteboard... like on Friends! Fun idea and great job, as always. Can't wait to get a 3D printer myself. :D
Great project in only 3 days! My first thought was to have a single sheet faceplate with the cutouts that moves back to flat against the back wall. The pieces would have to be thicker than the faceplate so they all fall out. You could use 4 steppers (one in each corner) with threaded rod to move the faceplate back creating the time up affect. And I’m sure MatterHackers has a few steppers and threaded rod there. A 3D Printer Arduino based board could have controlled the whole thing. Again, great project in only 3 days.
I get what you're saying. I think the problem was the lateral force against the flat end was too much for the solenoid to pull down. If it was on it's side, wouldn't the force be the same and it still not be able to retract?
It's kinda weird but if he put it on the sides it changes the application of the force. Also normally those type of set ups use 2 selenoids. At least thats what we had to do in the haunted houses for setting up stuff like that.
That is weird haha, interesting though. I did wonder if one on each side of the frame would've made a difference. And setting up haunted houses sounds like a fun gig, thanks for sharing. 👍
Awesome build!! An electromagnet door lock would probably have more than enough power to hold the rack back. When the timer runs out, power to the magnet is cut, the rack releases, and boing.
I think it's cool to see you use the tools you used. I've been working on a desk on and off for a few months. I live in an apartment so space is tight so I'm pretty much only using a circular saw, handheld drill, and orbital sander. It's an interesting puzzle to try to make due with what i have space for.
what an awesome project! this is such a large and complex project and with a time crunch no doubt. I totally understand how frustrating it can be to not have access to the right tools or the ones you are used to. BUT IT LOOKS SO BADASS! you really brought it to the next level.
Bob, the First Robotics Team I coached used a sliding door latch and a dc winch motor for a launching arm. Similar idea the winch motor wound against surg tube until the latch caught. Then.a simple servo released the latch. The force on the latch did not overdo the tiny servo
So Bob let me offer this, If you simply flip the rack over and mount it from the top it will cut down on the tensions you were getting . it will allow the solenoid to work. Great build Keep them coming.
Really digging this. I wonder if you could have used a small air compressor and tank to do the mechanism. When the game is started, the compressor begins to fill a tank with air. If the person fails, a valve release all the air under pressure, and out all the tubes. You could even have used a pressure gauge as like a “timer” and when the tank reached a certain pressure is when the game was over
You might consider using a pipe that can be pushed up and down using a servo (not those 9g servo's, but more powerful 1kg servos). That way, the PVC construction can get stuck behind the pipe and the pipe can be pulled down by turning the servo. It can't snap back very easily, but you could consider a button pulling down the pipe manually in order to snap the PVC construction back in place.
Maybe try a standard gate latch? The solenoid could easily pull a string/cable attached to the eyelet on it and there is a slope incorporated into the catch that helps start the forward motion......
Your discussion on the podcast inspired me to find a solution to my own project, on the principle of a mouse trap, for a pacifier trebuchet. Now my 1-yr old can get his binkie back without me going into his room!
Awesome Video and Awesome Channel! People like you make RUclips and the DIY atmosphere so much fun. You, along with 6 or 7 other channels on youtube have made me a better DIY'er and have also inspired me to start my own channel. Its always great to watch your top-notch content. Congrats on over 2 Million subscribers. Keep up the great work!
You can just use the para cord wit a ring or something on the end and a solenoid it can be hook to for the release and reset. set the solenoid on the side at the right spot so you can pull the para cord to it and create the tension on the pop out.. then when the timer is up the solenoid will release the para cord and the tiles will drop. just a little idea.. :)
Hey bob what you could do is put one of the flagpole/boating cleats so if one person was playing the could set it up them self and everybody else can work
You could try one of those electromagnet used to keep doors closed, it works with 12V and not much current (I use the 12V from an old PC power supply) and as long as the magnet and the plate are aligned, it is strong. And when you open the circuit, there is not mecanical friction.
Updates to make your ideas work (possibly) make the pvc piped that physically hit the pieces a tad longer so there is more travel to push the pieces out, as far as the latch for solenoid goes, use a small wheel that can spin with a bearing that catches on the latch, this way the friction is very low on the horizontal force from the wood and or 3D printed piece.
Have y’all tried using an 12v electromagnet to hold back the rack? I own and have designed and built all the rooms at Exodus Escape Games in Columbus, GA and those magnets are my go to for projects like this. If the rack is stiff enough, you’d only need one 600lb magnet (about $40) to replace that solenoid and the electronics can function more or less in the same way although swapping the mosfet for a relay might work better long term. Best of luck and thanks for sharing this video 😁
You can just use an electric magnet like the ones that can hold doors shut in place of the solenoid for the rack. They can hold a good amount of force when aligned properly.
Awesome project! If they’re planning on making some modifications to the game, may I suggest to make the patterns interchangeable for a change in difficulty and use pieces of wood as a grid to hold the patterns in place.
Looks like a fun addition to the office. Maybe a future video could be you helping them organize their tools! Really like the giant games, make some more... I'll watch them!
Awesome build, I would've used a "push" solenoid mounted horizontally at the bottom to kick the whole thing forward. Either that or go the over complicated route of using compressed air, regardless, awesome job
Nice Job Bob!!! I’m sad you decided to not use the solinoid, but I understand the concept of trouble shooting! Next time you should either use a relay to run a 110v solinoid( they are used for pinball tables and they are REALLY STRONG)! Also you could try some of the metal gear 35 Kg Servos! (I love those things!!) This inspires me to make a giant Connect 4 game with an arduino and neopixels!! Anyway cool job man!!!! Keep it up!! -Ava
I like how the game is about figuring it out before you run out of time, and you ran out of time before you had it fully figured out. You came really close though. It does look awesome and technically it does work, so good job to everyone who worked on it. I do feel your pain though, trying to do a project away from all of your tools. I have done a few things at my brothers house, 25 to 30 minutes away and I always try to grab what I can think of, but end up missing a few things. So I end up going to Home Depot with him so he can buy what is needed. Then it's his and I know it'll be there. Lol. Thankfully it's been small stuff.
Hey Bob, great video. Just a thought. Couldn’t you use the same idea of the solenoid and use an electric piston or something to push the rack laterally outward instead of latching and releasing with tubing. With a powerful/ fast piston you could control the tension and the push out in one mechanism.
I will be one of many using lots of time that you did not have to think of a better solution for the solenoid issue. No negativity here, you seem to have done the best with the time you had available. I would suggest trying a "fence latch" to hold the rack in place, with the solenoid pulling the release latch. This should place the tension on the latch and not require much force to release.
Maybe you should try to put a hook on your solenoid that would hold the reset rope in tension and release it when the time is up? That way you won't need someone to hold the rope while the game is on
Hey Bob, using a geared motor with and eccentric spiral motion similar to da vinci’s hammer machine should be able to drive the pvc frame under tension. It could just be 3D printed onsite @matterhackers.
Now hide a Murphy bed behind the next one, good for the extra long print sessions. Don't lie Bob, you chose that game because it was I Like To Make Stuff orange. I thought you would use a solenoid with a longer throw to push the frame, and the surgical tubing to auto reset it. Sucks that you guys didn't have time to prefect it, still came out cool though.
This was a lot of fun to watch and looked like a blast to build. I wonder if the solenoid could be used on the "handle" end of the reset cord. If the eyelets acted as pulleys and reduced the force on the flat side it might be able to retract easily? Just thoughts, if anyone has some insight on this I'm all ears haha.
Should have the solenoid outside where the string is, with a latch, so you can keep the tension off of the solenoid itself and still allow it to release properly
I love these videos! I have a suggestion, I think u should make more food related vids like how u did the ravioli rolling pin, I love those vids because there's food and they are always my favorite videos
Awesome game. What about using a magnetic lock to hold it in place? I’ve used magnetic door “hold opens” that release when power is removed. They are strong enough to hold fire rated doors open until the fire alarm kills power allowing the door to close.

Love this channel as an adult, but hated this game as a kid...so conflicted!!! Great job though! Suggestion: You could just have a servo pull down on the tensioning rope and release it when the time is up :)
Use a vending machine seliniod on each piece, from the kind of machine where the can just drops out of the bottom. It'll probably require a relay but it should have the throw and power you need.
Use a some kind of ram that sticks through the side to hold the cord handle under tension than pulls itself in to release the handle when the time is up. That is what I see in my head anyway.
Hi Bob, great channel. I have see all your stuff here on youtube, obviously you do a good job or I would not have watched everything. I was thinking of trying to make a Raspberry Pi CNC machine from scratch. I know you have a CNC already but when I look around on youtube for this type of project the others who have done it have made poor quality videos or worse a photo montage of a CNC build project. I really liked your Arcade build series and think you could make really good videos about building a CNC machine using a Raspberry Pi. I look forward to your future posts about any of the projects you take on.

To use the latch you need to turn it sideways and use the matching piece like it is in a door. That's the direction those were designed to operate at.

This video is really cool. What i would do for a bypass is add a high torque servo onto the end of the rope so that its still automatic.
The load on the latch is probably best reduced with a lever like mouse trap use.
It gets a little trickier to reset, but that should work, too.
Looks like a fun addition to the office. Maybe a future video could be you helping them organize their tools! Really like the giant games, make some more... I'll watch them!
pass on kudos to your sound designer. Music / sound really contributed & enhanced the viewing experience.
Thanks! ❤️✨
Congrats on two million
You can use a linear actuator. This way you can automate the timeout and the reset!
Hi Bob, great (literally) project. What if change the solenoid by a kind of electromagnetic device? I think this will gonna work!
How this video has not reached at least 3k likes is beyond me. Great vid
for longevity, might switch out that tubing for a light weight spring, since rubber dry rots
Finaly a project with electrics and stuff niceee👌👌
Congratulations for the 2 million Subscriber
Thank you!!
That was pretty cool. Great job both of you. I’ll see you next week. Bringing my wife so it’s going to be a blast.
Very cool. If I ever build one, I think a 12vdc Maglock would hold.
Needed a few more shots of it actually working. Can you keep us posted on the upgrade to the ejection of the pieces?

You could add a lock for the handle on the side as a release, instead of the back.
25 minutes! I’ll save this for later (gladly)
i am from Greece amd i watch ur vids aaaalways
Thank you or being real and showing how the game did not work as desinged but was still playable. Well done.

I remember when you weren't very confident on your welding abilities. Now you're building this kinda stuff and I'm a little jealous😋😂
This was a lot of fun to watch and looked like a blast to build. I wonder if the solenoid could be used on the "handle" end of the reset cord. If the eyelets acted as pulleys and reduced the force on the flat side it might be able to retract easily? Just thoughts, if anyone has some insight on this I'm all ears haha.
Magnets and relays is a good solution to the servo/PVC system problem. Next time you’re there! Or have them implement it!
When you use a normal power supply for your arduino (Which gives 12v), you can use vi (As a Volt in) for the 12v.
That's true, but the 5v supply also split off to run directly to the LED strips (so it didn't have to pass through the Arduino)
Really, really cool.
Should have the solenoid outside where the string is, with a latch, so you can keep the tension off of the solenoid itself and still allow it to release properly
I love these videos! I have a suggestion, I think u should make more food related vids like how u did the ravioli rolling pin, I love those vids because there's food and they are always my favorite videos
try solenoid valve and air compresser.
let the compressed aire pushes the shapes.
Awesome game. What about using a magnetic lock to hold it in place? I’ve used magnetic door “hold opens” that release when power is removed. They are strong enough to hold fire rated doors open until the fire alarm kills power allowing the door to close.
Wow! Great Idea I should make one of those😁👍🏼👏🏻
Nice Project!
You could replace the latch by a solenoid magnet 24vdc holding the frame thanks to a metal insert on it. De-energize the solenoid, it looses the magnetic field and releases the frame...
Eyelet on the reset string and have the solenoid catch the ring on the side instead of catching pvc round might work
Electromagnet came to mind. Might take more power and some pretty crazy magnets embedded in the pieces.
We had two of those in mind, but we didn't bring them. Good call.
@@JoshMakesStuff wait.. are you josh?
I can neither confirm nor deny the identity of "josh"
@@JoshMakesStuff haha. Good work, JOSH! 🙄
That's why I always came here. You are best bob.
That's very kind of you... thank you!
Could you use an electro magnet to hold the frame in position..? Then use the circuit for the old solenoid to power/release the magnet 👌
That is amazing!
I like the Skyrim waypoint market in the door next to the game at the end.
Love this channel as an adult, but hated this game as a kid...so conflicted!!! Great job though! Suggestion: You could just have a servo pull down on the tensioning rope and release it when the time is up :)
Wow amazing
Use a vending machine seliniod on each piece, from the kind of machine where the can just drops out of the bottom. It'll probably require a relay but it should have the throw and power you need.
I hope this goes viral.
