Kreg Band Saw Fence

April 7th, 2012 1 comment

I got a nice used 12 inch band saw, but this craftsman model doesn’t come with a fence.
So I bought a kreg fence.  Normally the installation would be fairly quick, but my table didn’t have any holes.
To me every problem is just an opportunity in disguise.  In this case, a chance to show how I drill and tap holes in metal.

Please check out my other videos on my gallery page.

Learning to Braze Metal

March 1st, 2012 Comments off

I wanted to create a new tool by combining 2 tools into one. I used a technique called brazing.
It is similar to electronic soldering but at much higher temperatures. The result is very strong.

You won’t need all the tools I show here, but the right tools will make the job easier.

The first version of this video received some constructive criticism on the web, so I redubbed the audio.. enjoy.

How to Build a WAMP Server

November 26th, 2011 11 comments

Instructions

This is the best WAMP installation guide on the net.
If you follow these notes, you will have a WAMP server running in the shortest time possible.

What is a WAMP server?
It’s a web server running on windows which uses at least 4 components.

  1. Windows
  2. Apache
  3. MySQL
  4. PHP, Perl, Python

A Linux based web server is called a LAMP server.
Except for the windows operating system, all of the components of a WAMP server are free (open source).
Although it can be used as a production server, a WAMP server is typically used as a development server.
A WAMP server is the best possible development platform for web applications.
You don’t have to keep synchronizing (ftp-ing) to a separate machine to test each code change.
You have ready access to the greatest diversity of support applications such as photoshop, flash authoring, … etc.
A WAMP server offers the greatest degree of Rapid Application Development.

These instructions are NOT for installing a packaged WAMP server.
If you want to install a WAMP server manually, then you’ve come to the right place.
The main advantage of a manual installation is greater flexibility.
You can create a server which is tailored to your requirements.
For example, the following instructions also include Perl and ImageMagick.

The trickiest part of a manual installation is making sure your components are compatible versions.
For example, not all versions of ActivePerl will work with a particular version of ImageMagick.

Fortunately, I have already done the hard part and determined the most recent compatible versions for a WAMP server.
To save yourself time and headache, I recommend that you use the versions I indicate.

All of the packages necessary to complete this installation are available in the following zip file:

WAMP-Files.zip

STEP 1: INSTALL PERL

Install activestate perl ActivePerl-5.14.2.1402-MSWin32-x86-295342.msi. (7-Oct-2011)

Be sure to install into c:\usr instead of c:\perl.
That way, you won’t have to change the top of perl programs from the linux standard value of #!/usr/bin/perl.
And your perl programs will easily migrate between linux and windows.

You can find the latest version at http://www.activestate.com/activeperl, but I recommend you use the version above.

STEP 2: INSTALL IMAGEMAGICK

Install ImageMagick ImageMagick-6.7.3-4-Q8-windows-dll.exe (12-Sept-2011).

Be sure to check the perlmagick option.
The dll version is a better choice than the static imagemagick.
The Q8 version of ImageMagick is twice as fast as Q16 and is good for web images.
You may have to reboot for changes to take effect.
Find all versions at http://image_magick.veidrodis.com/image_magick/binaries/.

STEP 3: TEST PERL & IMAGEMAGICK

Confirm your installation of ActivePerl & ImageMagick by running test_imagemagick.pl.

STEP 4: Install .NET

Install .NET Framework 4.0 dotNetFx40_Full_x86_x64.exe
This is needed for installing mysql in the next step.
Find at http://www.microsoft.com/download/en/confirmation.aspx?id=17718

STEP 5: Install C++ Runtime

Install Microsoft Visual C++ 2010 32-bit runtime vcredist_x86.exe
This is needed for mysql install in the next step.
Find at http://www.microsoft.com/download/en/details.aspx?id=5555

STEP 6: INSTALL MYSQL

Install MySQL server mysql-installer-5.5.17.0.msi (24 Oct 2011).
Uninstall any existing MySQL installation and delete the mysql folder to avoid problems with previous root password.

  • skip check for updates
  • full install
  • server machine for work and developer machine for home
  • Set root password = monkey (if your WAMP server will be a public server then choose a more secure password)

You can find the latest MySQL binaries at http://dev.mysql.com/downloads

fyi: I removed the default anonymous user account, otherwise attempting to connect to localhost may fail for other user accounts.

STEP 7: INSTALL PERL MYSQL MODULE

Install perl DBD-mysql module with perl package manager (under activestate program group).
Be sure to click “view all packages” (not just installed packages) when searching for DBD-mysql.

STEP 8: CREATE TEST TABLE

Now we need to setup a simple schema and table so that we can test our installation.
Run MySQL Workbench.

server host = localhost
username = root
password = monkey (or whatever password you chose during MySQL installation)

Create new schema name “mydb”.
Create a table=table1, column=name, datatype=varchar(20).

Add a user with username=alan and password=please (under user administration).

Assign privileges for user alan to schema mydb.

Which database table engine should I use? InnoDB or MyISAM?
MyISAM is faster than InnoDB.
MyISAM only supports table locking.
InnoDB supports row locking.
Therefore, InnoDB eliminates database errors caused by concurrent access.

Note: you can mix InnoDB and MyISAM tables under the same schema AND you can readily convert tables between the 2 formats.

STEP 9: TEST MYSQL

Confirm MySQL is installed properly by running test_mysql.pl.
It inserts a record into table1 and reads it back.

STEP 10: INSTALL PHP

Unzip php-5.2.10-Win32-VC6-x86.zip (17 June 2009) the files to a folder at c:\php

I have already updated the php.ini file. This table shows you the changes that I made.
If you download a newer version of PHP then you will need to make the same changes so that MySQL extensions can be found.

php.ini-recommended php.ini
display_errors = Off display_errors = On
extension_dir = “./” extension_dir = “c:\php\ext”
upload_max_filesize = 2M upload_max_filesize = 30M
;extension=php_mbstring.dll extension=php_mbstring.dll
;extension=php_mcrypt.dll extension=php_mcrypt.dll
;extension=php_mysql.dll extension=php_mysql.dll
;extension=php_mysqli.dll extension=php_mysqli.dll

Add “;C:\php;C:\php\ext” to the windows path
OR if your a real geek you can use the perl package manager (under the ActivePerl program group)
to install the Win32-Env module and then run update_path.pl.

In either case, you need to reboot to have the change take effect.

The latest version of PHP can be found at http://windows.php.net/download.

STEP 11: INSTALL APACHE

Install Apache win32 apache_2.2.11-win32-x86-openssl-0.9.8i.msi (05 March 2009).
(I chose the version that includes openssl encryption, just in case I’d need it).

Network Domain: localhost
Server Name: localhost
Admin Email: your@email.com

Change install folder to C:\Program Files(x86)\Apache2.2\ (not necessary, but it’s less obscure)

If apache won’t start because of a conflict with port 80, it may be due to skype.
If you have skype running you can’t start apache on 80. Just stop skype, then start apache and then start Skype (it only blocks 80 if it is already free).

Open your browser and go to http://localhost/ and you should see “It works!”
You can also use your machines ip address like this http://192.168.1.119/ or http://127.0.0.1/ and get the same result.

Copy httpd.conf to C:\Program Files(x86)\Apache2.2\conf\ (or where your apache install is located).
Modify all “Program Files” references in httpd.conf to point to your apache install location.

These are the differences between the original httpd.conf and the one I had you replace it with:

http.conf (original) http.conf (my modifications)
Loadfile “C:/php/php5ts.dll”
LoadModule php5_module “C:/php/php5apache2_2.dll”
PHPIniDir “C:/php”
DocumentRoot “C:/Program Files (x86)/Apache2.2/htdocs” DocumentRoot “C:/www”
<Directory “C:/Program Files (x86)/Apache2.2/htdocs”> <Directory “C:/www”>
Options Indexes FollowSymLinks Options Indexes FollowSymLinks ExecCGI
DirectoryIndex index.html DirectoryIndex index.html index.cgi index.pl index.php
ScriptAlias /cgi-bin/ “C:/Program Files (x86)/Apache2.2/cgi-bin/” ScriptAlias /cgi-bin/ “C:/Program Files (x86)/Apache Software
Foundation/Apache2.2/cgi-bin/”
#AddHandler cgi-script .cgi AddHandler cgi-script .cgi .pl
AddHandler application/x-httpd-php .php
AddHandler application/x-httpd-php-source .phps

Create c:\www folder (this is your server root).

Stop and start the apache server (look in the windows system tray for the apache server icon).
If apache fails to start, make sure the “program file” paths are correct in the httpd.conf file.
You can also check the apache error logs for messages.

You can find the latest apache binaries at http://httpd.apache.org/download.cgi.

STEP 12: TEST PHP

Validate the PHP installation and proper connection to MySQL.

Create folder c:\www.  Unzip php_test.zip to c:\www.
Open your browser to http://localhost/info.php
You should see the php info web page output with tons of detail on you PHP installation.

If the web page doesn’t appear, try rebooting to ensure all of the installs and changes have taken effect.
Also, check that the Apache server and MySQL server are running.

Go to http://localhost/mysql_test.php
You should see the output from mysql table1 (created above).

STEP 13: INSTALL PHPMYADMIN

Unzip phpMyAdmin-3.2.1.zip (09 Aug 2009) to a folder at c:/www/phpMyAdmin.

FYI: the config.inc.php file located in phpMyAdmin is already modified as needed
(it has the mysql root password set to monkey per above mysql notes).

Open your browser to http://localhost/phpMyAdmin.
You need to add a valid user and password using MySQL workbench and assign necessary privileges.

You can find the latest phpMyAdmin files at
http://www.phpmyadmin.net/home_page/downloads.php

STEP 14: YOUR DONE!

Your WAMP server is now ready for Perl, PHP, MySQL web development!
Please comment and provide feedback on this post. THANKS.
