I love the colorful light switches! Again I'm glad you felt inspired to create your own. I also developed 3 other prototypes before settling on this design so it's fun to see that you're also creating multiple iterations!

Amazing, thanks for sharing this! I'm glad that you got inspired to create your own unique design with flashing LEDs and a buzzer. Hopefully your idea inspires someone else to create *their* own version :)

Thanks for the positive feedback! Your design has inspired many people to build their own :)

Agreed, adding big plug-in wires would help young kids experience how a circuit is formed! In this design, I decided to avoid anything that my toddler could put in his mouth, especially since the plug-end of the wire would be electrified.

Great resources! And if you don't have access to local laser cutters, you can search for a company that will ship custom laser cut files to your home. Try using the search phrase "custom laser cut files shipped to home"

The only other material I've used is MDF but I don't recommend it's not as strong as plywood 👍

I've never heard of a terminal block, this sounds like a great idea!Agreed, the box can be assembled without a laser cutter! If you or anyone else has ideas on how to make the cutouts using manual tools, please add to this thread 👍

Thanks for drawing that diagram - upvoted! I'll keep this in mind when I do revisions to this Instructable.

Made an edit: CA glue is only intended to be used for the screws for the large acrylic window, not the battery cover.

It's true, I'm very fortunate to have access to a laser cutter. If you don't have access to a laser cutter or 3D printer, then please take this Instructable as inspiration to build something using the tools at your disposal, rather than a rigid step-by-step guide. In the video you'll see that my first prototypes were made of cardboard and hot glue!

There's a link to a specific Amazon product in the Instructable :)

The propellers are hard to make, I recommend buying prefabricated propellers with a metal hook and plastic craft stick mount.

Good catch - fixed!

So cool! Thanks for sharing :)

Wow thanks for sharing! It looks like it turned out great. You can reduce the blackened edges by either 1) lowering the power of the laser until it's just strong enough to cut the wood, or 2) speed up the laser. I recommend lowering the power and keeping the speed lower as well for best results. You can find more of my projects at STEM-Inventions.com. Cheers!

Good luck! Share a photo if you create one!

Hello! Yes it's possible to break up the tiles into pieces. The paths are not grouped. Just delete the green paths, draw new tiles, then select the parts you want to move and relocate them to your separated tiles. Hope that helps!

Hi! I'm not sure what's going on. I've only experienced that when the battery is old or has low charge. You could try a new battery, or wiring two 9V batteries together so the valve opens faster. Feel free to share a photo or video, I might be better able to help!

What a fun use for this project! Thanks for sharing.

This robot is not likely to work with 3mm chipboard unless you use glue to hold it together.

Way to make it work for you, and thanks for sharing! So cool to see that you've created your own Cart Bot!

Hey that's fantastic! Thanks for sharing :)

That's incredible! I hope you were able to fling things far!

Hello!Thanks for your feedback, and for sharing a photo of the completed project! This Instructable is quite old, but fortunately I just updated it on my site MadeForSTEAM.com. I've also revised the images and some of the text to make it more clear. Hope that helps in the future!

Hi - I'm not sure if the steering mechanism on that car is strong enough. My guess is that it would probably work, but you may need to make the trap trigger extremely sensitive. Good luck!

Hello, thanks for reaching out. I'm glad the project was a hit! This project needs to be thoroughly updated. The video and the pictures show two different ways of building it, depending on the tools and materials you have available. The washer is to be placed between the stand and the base to reduce the amount of friction between the cubes. The syringe adapter can replace the wood cube that's glued onto the end of the syringe. Sorry this is confusing for you and your students. I'll make a note to update this Instructable in the near future.

This used just 2 rolls of tape, one for the main color and one for the accent color. If you make one please share a picture here!

Honestly, it probably costs about as much as a store-bought Kayak (high quality duct tape and dozens of PVC connectors aren’t cheap!). However, what you can’t buy in the store is looks of bewilderment from onlookers. That’s priceless.

Thanks for the high praise! I'm glad you liked seeing the prototypes - I think it's important to talk about the process, not just the final shiny product.

Thank you! :)

Thanks! I think it's interesting and important to show some of the process, and not just the final product.

Hey that's me! I wrote Duct Tape Engineer :D

Thanks for alerting me. It's fixed!

Thanks for alerting me. It's fixed!

The green wood cubes are just 1/2" craft cubes. You can find them here: https://www.amazon.com/gp/product/B00XV13944?ie=UTF8

Hi - I don't know anything about that, but you can contact Instructables here: support@instructables.com. You can also find downloadable files on my website, https://www.madeforsteam.com/project-plans

Hi - You can hot glue a wooden cube with a hole in it to the syringe plunger instead of using a special adapter, like these ones: https://www.amazon.com/Wood-Cubes-Holes-Unfinished...Happy making!

It depends. For an adult, maybe 10 minutes. For a 6 year old, maybe 25 minutes.

Hello, sorry I don't know of any vendor that just sells the adapters. If I find one I'll be sure to link it here!

Looks like you need to make the sling to hold a projectile. You can find more details here as well: https://www.madeforsteam.com/slingshot

Hey, this is fantastic!! Thanks so much for sharing :)

Hello! I've long since discarded my templates - sorry. To create them, I just printed out silhouettes of images I found online, then traced them onto thin cardboard and cut them out for students to use. Have fun!

I recommend limiting the sticks to 40 or so, otherwise it's possible to make super-heavy robots that are difficult to move!

Hi - you may want to contact the Instructables team about how to download PDFs of Instructables. I don't have an answer for that.

It took about 30-45 hours, including the time to design the frame.

Hi - glad to hear these resources have been helpful! Here's how I support safe glue gun use: First, buy glue guns with an insulated tip and use only 10 watts. Introduce how it works. Point out the parts that get hot (the tip and the freshly melted glue). Demo how to use it (always put glue on the bigger of the two objects being glued together, keep hands clear, wait 15-20 seconds to dry). Explain how to handle burns (put burn under cold water immediately for as long as it hurts). When not using glue guns, keep them out in front of you. I like to draw simple houses on cardboard and tell kids to keep the glue guns in their house when resting.As they start using glue guns, make sure to coach them on proper technique and safety.Good luck!

It looks like the wheels are in stock again: https://amzn.to/2KMqcL3
