40+ Epic DIY Gadgets To Build For Geeks







We all love geeky stuff. But only Hardcore Geeks venture out to build geeky stuff. Today it is easier than ever to build your own gadgets at home! With tech parts & tools cheaper than ever (cheaper than a tank of gas at least by comparison lol) and tutorials a plenty out there – almost anyone can build cool stuff from home! Today we want to help you out and point you in the right direction with some of our favorite geeky DIY gadget projects we have seen so far.

What Is DIY?

DIY Stands for “Do It Yourself” if you didn’t know, here is what the wiki says about that

Do it yourself (DIY) is building, modifying, or repairing something without the aid of experts or professionals. The phrase “do it yourself” came into common usage in the 1950s in reference to home improvement projects that people might choose to complete independently.

In recent years, the term DIY has taken on a broader meaning that covers a wide range of skill sets. DIY is associated with the international alternative rock, punk rock, and indie rock music scenes; indymedia networks, pirate radio stations, and the zine community. In this context, DIY is related to the Arts and Crafts movement, in that it offers an alternative to modern consumer culture’s emphasis on relying on others to satisfy needs. The abbreviation DIY is also widely used in the military as a way to teach commanders or other types of units to take responsibility, so that they’d be able to do things themselves just as a preparation for their own future.

So are you ready to get your hands dirty and build some cool stuff? GOOD. Today we have everything from turning your old broken VHS into a toaster, all the way up to creating a real life talking Potato GLaDOS. Pretty insane eh? All of these things you can do yourself (with the right tools) and pretty much all of these have really good instructions on how you can obtain these tools and assemble them together to create these awesome things! NOTE: Be careful, some of them look fairly dangerous to attempt, be sure to read the disclaimers in the tutorials and follow the directions carefully – don’t want any infinigeeks out there losing their fingers :D . Also some of these are very kid friendly, so do them with your kids and teach them how to be a true geek!

Enjoy!

Make A DIY Steampunk Flashlight

Because regular flashlights are for newbs! Man up and build yourself a Steampunk Flashlight with these awesome instructions! You will never have hoped harder that the power would go out anywhere you are so you can use it all the time. *power goes out* “Oh nice flashlight, you must be some kind of a badass” :D

Build a DIY Tesla Coil In 9 Easy Steps!

As you know, Nikola Tesla was a BAMF. You can be a BAMF too by replicating a home made version of his Coil to impress your dog! When Nikola Tesla built his Coil, it was in an effort to provide the world with “Free wireless electricity.” He spent a fortune constructing Wardenclyffe Tower, a huge Tesla Coil in New York. His plan was to channel the electrical discharge emitted, to the earth. Through this approach, he believed he could electrify the Earth. With the Earth electrified, people around the world would be able to channel electricity by simply pounding some sort of metal rod into their yard. Wardenclyffe Tower was never fully operational, and was demolished in 1917. Many modern scientists are skeptical that this idea would’ve worked. But he was still badass, and inspired generations of Scientists after him. So yeah give this little DIY Project a try, but be careful!!

Build a Light up and Talking PotatOS from Portal 2

This is probably one of my favorite DIY Gadgets! So EPIC! As many of you do, I also loved the portal games, Portal 1 and 2 – this would be the perfect toy to have on your desk, just so awesome (and GLaDOS is hilarious.) This one actually lights up AND TALKS!! SO COOL.

DIY Kids Mega Man Costume

Ok this isn’t *really* a gadget, BUT, its geeky, awesome and adorable so deal with it! plus it does involve some LEDs haha :D I actually have a little guy about that size that would love this costume for halloween! If you are a geek with geeky-centric kids then perhaps consider making this for them this year! (or something similar) Looks awesome!! Can’t beat retro, classic Mega Man!

How to make a DIY VHS video toaster

This is just awesome. I know you all have a VHS player laying around somewhere collecting dust (I used to watch maybe 1 VHS a year until YouTube pretty much replaced my need haha). Now you can breathe new life into your old abandoned VHS tech. Make it a Toaster! Toast it up! (coincidentally enough I Have “The Brave Little Toaster” on VHS haha – remember that movie? It was great.)

Build An Earthquake Detector

This is really awesome if you are interested in earthquakes, or live in an earthquake prone area (such as California, as the girl who created this mentions in her video) if nothing else its a neat little project to do with the kids or on your own for some geek DIY experience (street cred? haha)

How To Build A R/C Steam Turbine Tank

Speaking of awesome. THIS. is awesome. Part geeky, part artsy, and full on WIN – this thing really does run on STEAM, and yes, it is a TURBINE. At this point you are drooling, so check out the video on this one and if you feel so inspired as to build your own, you can! Go do it! Have fun!

How To Build A Retro Futuristic Nixie Tube Geiger Counter

Not sure where this would come in handy, but it looks AWESOME. I just want to build this bad boy, and take a trip to Chernobyl and let the good Geigers roll lol. If nothing else it would make an excellent conversation piece!

DIY PVC Pipe Clock

Awesome! I love minimal designs on pretty much anything, and the way this PVC Pipe Clock is made is really simple and minimal, and I love that. This is a rather simple tutorial compared to some of the other DIY Gadget projects with massive instructions or required tool lists.

DIY LED Matrix Glasses

Wow, these glasses are the hotness. Be the coolest geek in the club with these LED Glasses – check out the video for some of the slick animations it can do! Looks like a pretty complicated process according to the directions but is definitely a do-able weekend project!

NINJA TURTLE OOZE!

Build Your Own Speaker From Scratch

This is really cool if you are interested in how speakers work (i’ve always been fascinated by them myself). Get your hands dirty and build one from scratch! I can already think of a ton of scenarios that you could use this as foundational knowledge to build something bigger, and more awesome than just a speaker!

Create An Arduino Powered “ButtonHero” Game

This is pretty cool if you are into DIY Electronic & Arduino stuff. Basically this D-I-Y gadget involves the use of buttons, LEDs, wires, and resistors. In this game, you have to hit the corresponding button to the light that is randomly selected before the light changes. You start with 5 lives and missing or being too slow subtracts one life. The high score at the moment is apparently 56. haha

How To Build A Steampunk Keyboard

Another one of my favorite DIY projects – especially of the steampunk variety. So Cool. I would like to have this as my keyboard, this timeless design would never get old! It looks like it would be fun to type on as well with all those curvaceous circle buttons! If you are a steampunk geek into tech and other gadgets, this is a must do DIY project!

The Ultimate Nerf Vulcan Mod

Oh man this one is awesome, I’ve actually been wanting to do this one for a while myself, its a little old (its from 2008, so old by internet standards haha) but still worth mentioning as I believe they still sell the gun in stores (last time I checked), as its one of my favorite nerf gun modifications EVER. Ever since I saw this thing in action in a youtube video (seen below) I was having a hard time controlling my saliva glands.

Portal 2 “Pillar Button”

This is another awesome portal related DIY Gadget. I could see this being an awesome lamp or some other type of light source for around the house, maybe next to the TV :D Love it!

How to make a Portal Gun

Ohhhh sweet mother of god. Really nice Portal Gun replica tutorial! Would make a really great cosplay accessory or go with a costume for Halloween!

The Word Clock – Arduino version

I am a big fan of word clocks like this – if you are too, then you can build your own! I love the minimal and functional design – this would make a really great addition to any room! Do it for yourself or do it for a gift for someone! Geektastic!
