Instructables user grandpapaning has built this pretty neat tap-dancing robot. In actuality, it serves no purpose whatsoever. In practice though, it’s a great way to teach people about the different areas of science – Electricity, electronics, mechanical design, turning electrical signals into physical forces. In general, lots of stuff. It’s all pretty neat really. There’s still time left in this Christmas vacation. Maybe you should look at building this useless thing.
This isn’t your dad’s Periodic Table. This isn’t even your meme’s. This is something different.
Makendo from Instructables has built this really neat cylindrical periodic table lamp. It’s pretty ace if you ask me. Unfortunately, it requires access to a 3-D printer, or some really insane skills with a Dremel/router/bandsaw.
I like Hexagons, they are cool elements (pun intended). I’m not that big of a fan of the color scheme he chose, but this is his lamp, so let it be.
I think it’s pretty neat that he’s attached vials containing the actual elements to each hexagon. He only has 20 of them filled in right now, but it’s a great idea. I do not like the way he has them protruding from the lamp. It’s easy to get things tangled up on them. I would have attached them horizontally across the middle of each hexagon. Again though, this is not my lamp.
It’s neat, unfortunately, I don’t have the full means to build something this complicated just yet. Maybe one day though. I can add it to my collection of other things I have no place to display.
No doubt about it, electric trains are cool. They are expensive though. And you could get called “a nerd.” But really, those people are just not cool, so there.
Follow the simple 4 step instructable to make “The Simpliest Electric Train“. Now, watch the video of it in action. It’s quite cool. Except the jumps, that part sucks, don’t build this expecting to get some sick jumps. You’ll be dissapointed.
If your kid, or brother, or friend wants a Train for Christmas. A. Get them one, (if they’ve been a good child that is). B) If they like trains, then they’re probably interested in science. Why not spend $20 and make this with them. It will be cool and get them interested in science.
This Instructable will show you how to make your own Gallium Spoon. Unlike the trick spoons from the movies, this won’t form back into a spoon when you take it out of the water, or soup. Also, I’d make sure you have lots of extra soup, because while gallium might be non-toxic, I don’t think most people would be ok ingesting it.
I’m not sure exactly why someone would do this, but this is America, you can do anything you want. So Insturcables user mikeurus used his ingenuity to power a blender with a chain saw. It’s a great conversation piece, but it’s not something you’ll keep on your counter at home, too much toxic exhaust to keep around the kitchen I think.
Instructables user darbinorvar put together this really cool LED lamp that lights up like stars. You can watch her build the whole thing in her YouTube tutorial of the process below if you want. It’s better then going through all the photos individually and remember, I’m lazy.
I really like the random way she marked where the stars should be. It gives it a much more natural look. I’m not 100% sure that she needed all of the LED strips she used, but hey, it works, and it only uses about 6W fo it’s all good.I’m very happy that she used warm-white light, it’s muchnicer then the harsh white light.
Yes, a 3rd lamp post this month. Sue me. Instructable user Trask River Productions has put together a very comprehensive 34 step instructable on how to make this really good looking Log lamp shown above. Honestly, it looks very well made, which makes sense considering the person/company. I’m impressed with cutting out all the wood from the base to get the the electronics to fit. I would have expected it to be in an attachment to the base. I bet they could (and hopefully do), sell these for $100, there’s quite alot of work that’s gone into them.
They used a regular log and cut it into sections:
After the pieces are cut, holes are drilled in each one to run the tube:
I was going to show more photos, but why bother when you’re better off reading the Instructable yourself. This way you get all the correct information straight from the source. If I had a place for something like this, I’d make it, but I have no room anywhere, so it’s not worth it, not yet anyway. The one change I would make is instead of a regular light bulb on the top, I’d continue the LEDs up there. Make the whole thing LEDs, it’s better. They have warm white LEDs too, so it’s all good.
Instructables user Jazzmyn has designed her own pieces for a marble machine. They’re pretty basic parts, curves, switches, and Ys. But they all connect together and in whatever way you want to combine them. You can download the parts on Thingverse, but you will obviously need a 3D printer in order to build your own.
Here’s a video of the finished machine. It’s pretty nice, but there is some room for improvement in future
This is pretty neat, if a bit useless for the average person. Instructables user MaskMarvl has put together a quick 7 step guide to making your own sugar cubes. Granted, it needs to use brown sugar so that it can stick together, but I’m sure you could eventually figure out the recipe for making your own white sugar cubes.
The whole process is actually quite easy and could probably be completed without the tools asked for, just two pieces of wood, and a drill. The sugar cube isn’t needed, make it whatever size you want, this is America after all.
Part of the fun of bubbles is not knowing what you’re going to get. Not knowing how many, or how large, or how long the bubbles are going to be. They are unpredictable. Gordon Kirkwood decided to take the unpredictability out of them. He made what he calls the CNC Bubble Iris. The entire thing is so overly-complicated that you will wonder what it is if you didn’t see it in action. He has a whole 19 step Instructable on his build. I’ll give him credit for making it very detailed, but still, it’s bubbles. Why does this much effort need to be spent on it?
Here’s a video of the Iris in action:
All that being said, I have to admire the engineering behind this. This is very well thought out, and very well made. Professionally made. I just question the necessity of it. But then again, many of the greatest things have no practical use, they are just cool. And with as much negativity I have had towards this, I think it’s cool.
