10 DIY Electronics Tutorials You Must Try!

There are a lot of things in electronics that you can do by yourself. You don't need to be a pro and you don't need to know the subject in depth. Of course it helps if you do, but you can simply follow directions and make your own stuff. Here are 10 do-it-yourself projects that you can have fun with!

1. DIY Contact Mic - Collin's Lab

It's amazing what a little disk can do ... when it's layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp - a basic circuit used to match the piezo's signal to levels compatible with modern audio gear inputs. The resulting piezo/preamp combo can be used for electrifying an acoustic guitar or simply exploring the lesser-heard world of small sound around us.

2. DIY LED Light Bulb

LED is the latest trend. So, create your own LED bulb with the help of this video and lighthen up your space.

3. DIY-Make A Secret Hidden RC Hard-Drive

This circuit makes a hidden emergency HDD to be controllable only by your key,regardless of how many people use the same computer. This HDD should be used only for copy and paste, because of low power of relay batteries, if you want it to work longer, add more batteries using parallel connection. Or use a stronger RC Circuit. This is an electronic Hack to protect the data from Software Hackers,or some-one you don't want him to access your data.

4. DIY Mini Quadcopter Scratch Build Introduction - 3D Printed Frame, Cheap Electronics, and MultiWii

The Blade mQX Quadcopter is the inspiration behind this project. The maker was frustrated by expensive replacement parts as well as how difficult they are to get. So he decided to experiment with a DIY scratch build using 3D printed parts as well as parts that are easy to find.

5. Cool DIY Solar Tracker Self Powered No Electronics - How it Works

This is a brilliant simple idea for a homemade solar tracking model using a few easily available components and minimal assembly at almost no cost. It makes sense by powering itself and without using electronics or sensors. Presented here as a sixth grade instruction and explanation set for a science project with clear animations and scientific explanations of the physical principles with diagrams behind the workings of the model that were readily understandable and motivating to young students. The video ends with food for thought to encourage creativity and problem solving with more diagrams and animations of how to scale up the model into a low cost practical do-it-yourself device to produce alternative energy. This also inspired indirect student interest in producing this video as a technical presentation to explain the idea using MS PowerPoint, Movie Maker, and Google Sketchup to make 3D models and animations.

6. DIY Body Scanner Electronics

The video shows how the capture hardware was constructed for the DIY body scanner.

7. DIY Electronic Drum Pads for Midi and simple drum kit

Here's a video that shows how to build an electronic drum kit for really cheap, using pie pans and pizzi transducers.

8. DIY Audio Amplifier

This video shows you how to build a simple audio amplifier that can be connected to any device with an audio output jack (such as an iPhone).

9. DIY Electronic Eyepiece for telescope

This is a quick tutorial on how to build your very own electronic eyepiece for your telescope.

10. DIY Series: Repurposing a CD Drive

The maker of the video says, "The desktop computer has moved past many milestones in its evolution towards perfection, upgrading from one version to another and based on increasingly sophisticated components. An old computer is usually sold part by part and replaced by a new one. It turns out that a part that is almost always left behind is a CD drive, which will provide the basis for our device. To operate, the drive will need a power supply. Well, we could use the original one used in the computer. However, old computer power supplies are notoriously unreliable in the long run, which is known to have caused many motherboards to inflame. In this case I used a power supply from an old DVD player that somehow managed to escape the dump. Power supplies in such devices are often preserved fully intact. Its design allows connecting the computer drive with a standard adapter cable that doesn't need to be adjusted or reworked in any way. Also, the supply is included in the player as a separate unit with its own connectors. The only thing needed is a casing for the power supply. Here you are free to use your creativity."
