Nitroglycerin Recipe
Like all chemists I must advise you all to take the greatest care
and caution when you are doing this. Even if you have made this stuff
before.
This first article will give you information on making
nitroglyerin, the basic ingredient in a lot of explosives such as
straight dynamites, and geletin dynamites.
Making nitroglycerin
1. Fill a 75-milliliter beaker to the 13 ml. Level with fuming
red nitric acid, of 98% pure concentration.
2. Place the beaker in an ice bath and allow to cool below room
temp.
3. After it has cooled, add to it three times the amount of
fuming sulferic acid (99% h2so4). In other words, add to the
now-cool fuming nitric acid 39 ml. Of fuming sulferic acid.
When mixing any acids, always do it slowly and carefully to
avoid splattering.
4. When the two are mixed, lower thier temp. By adding more ice
to the bath, about 10-15 degrees centigrade. (Use a
mercury-operated thermometer)
5. When the acid solution has cooled to the desired temperature,
it is ready for the glycerin. The glycerin must be added in
small amounts using a medicine dropper. (Read this step about
10 times!) Glycerin is added slowly and carefully (i mean
careful!) Until the entire surface of the acid it covered with
it.
6. This is a dangerous point since the nitration will take place
as soon as the glycerin is added. The nitration will produce
heat, so the solution must be kept below 30 degrees
centigrade! If the solution should go above 30 degrees,
immediately dump the solution into the ice bath! This will
insure that it does not go off in your face!
7. For the first ten minutes of nitration, the mixture should be
gently stirred. In a normal reaction the nitroglycerin will
form as a layer on top of the acid solution, while the sulferic
acid will absorb the excess water.
8. After the nitration has taken place, and the nitroglycerin has
formed on the top of the solution, the entire beaker should be
transferred slowly and carefully to another beaker of water.
When this is done the nitroglycerin will settle at the bottem
so the other acids can be drained away.
9. After removing as much acid as posible without disturbing the
nitroglycerin, remove the nitroglycerin with an eyedropper and
place it in a bicarbonate of soda (sodium bicarbonate in case
you didn't know) solution. The sodium is an alkalai and will
nuetralize much of the acid remaining. This process should be
repeated as much as necesarry using blue litmus paper to check
for the presence of acid. The remaining acid only makes the
nitroglycerin more unstable than it already is.
10. Finally! The final step is to remove the nitroglycerin from
the bicarbonate. His is done with and eye- dropper, slowly
and carefully. The usual test to see if nitration has been
successful is to place one drop of the nitroglycerin on metal
and ignite it. If it is true nitroglycerin it will burn with
a clear blue flame.

How to make Potassium Nitrate
Potassium Nitrate is an ingredient in making fuses, among other
things. Here is how you make it:
Materials needed:
-3.5 gallons of nitrate bearing earth or other material
-1/2 cup of wood ashes
-Bucket or other similar container about 4-5 gallons in volume
-2 pieces of finely woven cloth, each a bit bigger than the
bottom of the bucket
-Shallow dish or pan at least as large in diameter as the bucket
-Shallow, heat resistant container
-2 gallons of water
-Something to punch holes in the bottom of the bucket
-1 gallon of any type of alcohol
-A heat source
-Paper & tape
Procedure:
- Punch holes on the inside bottom of the bucket, so that the
metal is"puckered" outward from the bottom
- Spread cloth over the holes from the bottom
- Place wood ashes on the cloth. Spread it out so that it covers
the entire cloth and has about the same thickness.
- Place 2nd cloth on top of the wood ashes
- Place the dirt or other material in the bucket
- Place the bucket over the shallow container. NOTE: It may need
support on the bottom so that the holes on the bottom are not
blocked.
- Boil water and pour it over the earth very slowly. Do NOT pour
it all at once, as this will clog the filter on the bottom.
- Allow water to run through holes into the shallow dish on the
bottom.
- Be sure that the water goes through ALL of the earth!
- Allow water in dish to cool for an hour or so
- Carefully drain the liquid in the dish away, and discard the
sludge in the bottom
- Boil this liquid over a fire for at least two hours. Small
grains of salt will form - scoop these out with the paper as they
form
- When the liquid has boiled down to 1/2 its original volume let
it sit
- After 1/2 hour, add equal volume of the alcohol; when this
mixture is poured through paper, small white crystals appear. This
is the posassium nitrate.
Purification:
- Redissolve crystals in small amount of boiling water
- Remove any crystals that appear
- Pour through improvised filter then heat concentrated solution
to dryness.
- Spread out crystals and allow to dry
things. Here is how you make it:

How to recover MOST of scratched CD data discs
I learn an old thecnique to how to recover damaged or scratched disks
with some lost of data. In this case i have one borrowed game - MAX PAYNE 2
with a chunck of 4 mb lost with a scratch in CD1 Install. Here we cover some
special thecniques of how to create a full working CD from the scratched one.
First some tools will be needed:
1. Alcohol 120%
2. UltraISO
3. Windows XP/2000 (not tested on 95/98/me)
3. Small piece of cotton
4. Dry cleaner paper
5. Finally, oil for cooking.
First step - preparing the CD
Get the cotton and drop some water, start cleaning vertically the surface of CD.
Do it 3 times and dry the water with a piece of dry cleaner paper. With a new piece
of cotton, drop some oil for cooking and start to wet the surface like you are
washing the CD with the oil. Dry carefully now. Some particles of oil will stay on the
microsurface of the scrath. It's okay. Seems the oil helps the laser of the CD/DVD driver
to read the surface again. Sure this will work with small unreadable scratchs - some hard
scratchs loose parts of the surface of the CD where we have data and it's lost forever.
But if it is loosed try anyway. Whith this tip 80% of the small scratched CD's coud be
recovered.
Second Step - testing the CD
With Alcohol 120% make an ISO - image making wizard - and lets see if the app can
read the loosed surface. In my case Alcohol 120% had recovered 60% of the data.
This is not enough. Have tryed other appz, they do not recover all the data. But the
CD/DVD driver laser CAN recover all data in this case. the data is still there, what we do?
third step - making the new CD
With the main copy system of windows explorer you can do it. Just create one folder
with the same name of the CD label for future burn reference, and copy the CD content
to the folder. When the CD copy process find the scratch, in majority of the cases, it's
slow down the reading and will recover ALL loosed data.If not, it just tell you there's
an unreadable sector. In this case your CD is lost. But it's not my case, finally
windows explorer got all the data from the scratch and made a copy in the folder.
with the ultraISO, wrote the original CD label, drop the content of the folder and
save as Iso. You can Test the new CD just mounting the iso in the Alcohol 120%. In my
case i did ISO of the two discs from MAX PAYNE 2 and tested installing from the mounted
ISO. Works like a charm. I got the 4 mb lost again. So, I have burned the CD and now i
have a working copy from the scratched one.
Sounds too bizzarre, but works. Course you can jump the cleaning process and try to copy
the content with Windows explorer. But in my case did not work without oil...

Beep Code Manual
BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix.
Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.
AMI Beep Codes
Beep Code Meaning
1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard.
2 beeps Memory parity error. The parity circuit is not working properly.
3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory.
4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard.
5 beeps Processor failure. The system CPU has failed.
6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
7 beeps Virtual mode exception error.
8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card.
9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty.
10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS.
11 beeps Bad cache memory. An error in the level 2 cache memory.
1 long beep, 2 short Failure in the video system.
1 long beep, 3 short A failure has been detected in memory above 64K.
1 long beep, 8 short Display test failure.
Continuous beeping A problem with the memory or video.

23 Ways To Speed WinXP
Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.
1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.
2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.
3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.
4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.
The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.
Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.
Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.
5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.
6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.
7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.
8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.
9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.
10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.
11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.
12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.
13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.
14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.
15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.
16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.
17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.
18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.
19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.
20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.
21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.
22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.
23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.
Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.
1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.
2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.
Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.
Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.
5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.
6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.
7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.
8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.
9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.
10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.
11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.
12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.
13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.
14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.
15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.
16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.
17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.
18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.
19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.
20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.
21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.
22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.
23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.
Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.
