Before starting it’s good to know that Tesla Coil is not a toy at all and can be very harmful. When you power on DO NOT TOUCH IT WHILE ON UNDER ANY CIRCUMSTANCES. We don’t take any responsibilities for hurting yourself or others while building this machine. In this tutorial you will learn how to build yourself a TESLA COIL.
Step 1 – Gather all the materials needed to build a Tesla Coil
Total can go up to $30
As for the Secondary Coil:
A length of 1.5″ PVC (if is longer is even good)
About 300 feet of 24 AWG copper enameled wire
1.5″ PVC screw-thing (as in pictures)
1.5″ metal floor flange with threads
Spray on enamel
Circular, smooth metallic object for the discharge terminal
Base and Supra-base
Various pieces of wood
Long bolts, nuts, and washers
About 10 feet of thin copper tubing
6 Glass bottles (Snapple bottles is recommended)
Oil (I used canola. Mineral oil (horse laxative) it preferable as it doesn’t mold.)
Lots of aluminum foil
And a HV power source such as a NST, OBIT, or other transformer that gives off at least 9 kV at around 30 mA.
Step 2 – Start building the secondary
Make sure to wrap one end of the wire around. Slowly and carefully begin to wrap the coil, making sure that you don’t overlap wires or have spaces. This step is the most difficult for many of you and most tedious part, but taking a lot of time will yield a very nice coil. Every 20 or so turns, put a ring of masking tape around the coil to act as a barrier if the coil starts to unravel. Once finished, wrap a tight piece of tape around the top and bottom of the coil and spray it with 2 or 3 coats of enamel.
Step 3 – Prepare the Bases and finish the Primary
On this step you should align the metal stand in the center of the bottom board and drill holes for bolts to go through, after that attach the bolts upside down. This will allow to put a base for the primary on top of it. Then bolt the primary’s base in. Take your pipe and wind it into a pretty upside down cone (not the flat spiral in the pictures). Then mount it on the supra-base.
Step 4 – Build yourself capacitors for Tesla Coil
This can be a tricky part if you don’t know exactly what you’re doing. Please pay attention when building the capacitors using salt water, oil and aluminum foil. You should wrap the entire bottle in foil, and fill the bottle with water. Pay attention to the quantity of water. You should have equal amount of water in each bottle. It will keep the power output at the same level. The maximum amount of salt you can put in the water is .359 g/mL, but this ends up being a lot of salt, so you can tone down the amount a lot (I used 5-6 grams). Just make sure that you use he same amounts on salt and water. Now put a few mL of oil slowly into the bottle. Punch a hole in the top of the cap and put a length of wire in it. You now have one fully functioning capacitor, go make 5 more.
Step 5: Wrap Everything UP
Please pay attention to the schematic. Keep in mind that the seconday ground cannot be put on to main ground, this is extremely important.
Step 7: See the Tesla Coil in action!
For the first run, if you’re not sure of what you’ve made, please go with the entire machine outside and take all the necessary precautions to avoid putting yourself or others in danger. Now, toggle the device on and enjoy the light show.
A friend of mine asked how he can convert the favorite songs to plain songs without lyrics. I’ve found a way and I want to share it with you guys, even if most of you are not so techie. With this method of removal you can convert your songs to Karaoke ready songs. You should know that with this method you won’t be able to get rid of the singer completely but it will be suitable for your Karaoke song collection.
Step 1 – Download Audacity:
Search on google for this software, download and install in on your computer.
Step 2 – Open the song:
Click on file, select the designated song to have the lyrics removed. Please make sure this song has the both bars (is stereo) otherwise it won’t work.
Step 3 – Split the stereo track
With this method you will split the stereo track in two different tracks for left and right. Don’t worry, nothing is broken …yet 🙂
Step 4 – Invert Right Audio Track
First of all, please make sure the song is not playing for this part. Now you have to invert the audio in the bar placed on the right. Just click anywhere on the grey part of the bar, go to Effects from the menu and select invert. On completion the right track will look changed.
Step 5 – Change to Mono
In this step you will have to change both left and right tracks to MONO.
Step 6 – Enjoy the song.
Well, you have successfully edited your first song and remove the lyrics from songs. I am sure you will have many others to edit from now on, but you did it. If you want you can save the song to WAV or MP3 and listen with your favorite media player software.
The most easy way for anyone to create a USB devices who’s able to boot, will be described in a few steps. When you will complete this steps, you’ll be able to work with your new USB stick.
You will need the following:
1. An empty USB stick (at least 8 Gb)
2. A computer with an ISO image ready to be written on the USB.
3. This software who is going to help you building the Bootable USB device
Ok, now you should unzip the newly downloaded archive and start the software.
Please make sure that Create a bootable disk using: option is checked, this is very important, otherwise your PC won’t be able to boot from the USB drive.
When you press the START button, it will start working. You should wait now until the process is finished. The waiting time may vary based on the size of the ISO image used. It may take from 2-3 minutes up to 15 minutes to finish. This method works with both Windows and Linux image ISOs.
And that’s it. If you want to make sure the newly created usb is bootable, you can read this post and find out how before you can try the USB on your PC or laptop.
Well folks, today I’ve encountered a big problem trying to upgrade a LENOVO H500S bios. First of all, you have to know that Lenovo support is missing, at least for this model. But I’ve found out a solution so you can upgrade the bios and be able to boot Windows 7, Windows Vista, or Windows XP on this machine type. Here is a photo of the old BIOS model:
For some reasons, Lenovo doesn’t put too much effort in releasing a hassle-free method for the user. But here is what I’ve found, and if you are in the same situation (Bios upgrade) and want to install another operating system, just follow these easy steps:
Download the Make_PE3_48.exe file (don’t worry, it’s virus free, but for your peace of mind, scan it anyway).
Start the file
Select where you want to create your ISO file (all the content will be extracted from your current operating system if you don’t have an iso at hand – which was my case).
When the entire operation is completed, download the RUFUS bootable USB maker from here
Select the ISO previously created by the Make PE3 file, at the step 3 and make the USB bootable.
Well, I’ve encountered yesterday a problem. I’ve made a bootable usb for a friend and even if I’ve followed all the steps required for this process the stick didn’t wanted to boot the device (a laptop in this case). I’ve searched the web for a solution to check before rebooting and re rebooting the computer if the USB device is really bootable or not. The solution is simple enough for anyone and you can test if the drive is bootable before going all the nine yards. Here are the steps to take:
Open the archive and extract all its content to the designated USB device you would like to check
Open the path to the USB Drive and run the program with administrative rights (use mouse right click – > Run as Administrator)
When you start the program a dialog will appear asking if you wish to use the Qemu engine. Just say yes, of course. Ok, when you will do that, the software will test itself the USB to find out if it’s really bootable or not, without rebooting the PC over and over again.
Most people when hear about using command prompt will search other way, but creating a bootable usb pendrive using command prompt is not that hard as most people may thing.
This method is designated to be used by people who don’t have windows 8 installed on their computers. Don’t try to make it work on windows 8 machines, cause it won’t work. To make a bootable usb pendrive follow these easy to do steps:
1. Go where the ISO files are located (even if we talk about a CD/DVD content or a mounted ISO). Copy those files to a designated folder on your hard drive.
2. Insert your USB drive into your computer press the start button and in the search field type “cmd“. When a black box will appear on the search results, right click on it and select to run the program as Administrator. A new window will appear which is called the command prompt. On it, type the following sequence of commands:
diskpart (press enter)
list disk (press enter)
select disk (#disk number) – recognized by its size (press enter)
clean (this will erase the selected disk – press enter)
create partition primary (press enter)
select partition 1 (press enter)
active (press enter)
format fs=ntfs quick (this command will format the newly created partition – press enter)
When the format is over you still have to give some commands in order to make the usb pendrive bootable. Here they are: assign (which will assign a letter to your usb drive) and exit
Remember that i’ve instructed you to extract the content of the CD/DVD to a designated folder at the beginning of the article ? Now it’s time to go there and find the boot folder with the bootsect exe file
I have the following path: e:\cd win 7 sp1\boot\bootsect.exe/nt60 h: (where H is the drive letter of my future bootable pendrive)
All you have to do now is to copy all the files found here to your usb device.
Everything is in place right now, you can restart your computer and boot from your newly created bootable pendrive.
As you already know, you don’t need to be a professional IT engineer or IT geek to make a bootable USB Device. This method is valid if you have installed Windows 7 on your computer. You cannot do this using other version of Windows.
I will not insist on the file sources (from where you have them). I will try to explain as good as I can how to make the device bootable.
1. Get the Windows ISO files on your computer hard drive (even if you copy your Windows KIT).
2. Insert your USB drive in your pc, press the start button and in the search field write CMD. Right click on the first result (the one with the black icon) and select from the new opened menu selection “Run As Administrator”. A black window will appear, called “command prompt”. Now you should type the next commands one by one:
DISKPART LIST DISK SELECT DISK # (where # is the disk number – make sure you select the correct disk, check the disk size and make sure it’s the correct one). CLEAN (it will erase your disk, so please make sure you have selected the correct disk at the previous entered command). CREATE PARTITION PRIMARY SELECT PARTITION 1 ACTIVE FORMAT FS=NTFS QUICK (will format the disk using NTFS tables lightning fast 🙂
3. When the format is done, write the following command:
ASSIGN (the system will give a letter to your newly created bootable USB device). EXIT (it will exit the disk part program which helped you to create your bootable device).
4. At this point you should make the usb drive really bootable. Go to your previously saved kit and find the boot folder where you should locate the bootsect file.
5. In this case, i had to give the following command: CD e:\”win 7 sp1\boot” and after that E:. After that I had to type bootsect.exe/nt60 h: (where H is the drive letter)
When this step has been completed, you should be able to boot from your USB device like a pro !
I’m sure you’ve wanted to create a bootable disk or bootable USB at least once for various reasons. You should know that this method is not at all complicated, in fact is easier than you may think. Yes, I know it sound too geek but if you follow the steps from this tutorial, you can do it yourself even if you’re not a pc guru at all.
First step is to download the ISO Image (the disk image with Windows 7 or Windows 8 – your flavor). Next logical step is to install a cd/dvd burning software, personally I use the free tool called IMGBurn, which is more than I need. Well, the hard part has just been passed 🙂
I will assume that you already have the ISO file (image file for Windows).
1. First step is to download the tool provided by Microsoft on their webpage called Windows 7/USB/DVD Download Tool. This tool works very well even for Windows 8, don’t be fooled by it’s name. It’s intended to work with all their software.
2. Select the input files in order to create a bootable USB. Simply choose the ISO that you already have.
3. Device selection. On this step you should select the destination for your new bootable device (Bootable USB, Bootable CD/DVD).
4. Choose the USB port. First you need to connect the USB to your computer. Also, please make sure that your device is big enough to avoid making all the steps again with other USB Device.
5. Wait until the process finish. This software will format the USB drive first in order to make it bootable. When this process is finished, it will start to copy files on the device. Depending on your computer and USB port speed it may take between 10 to 30 minutes.
