Here’s a cool blog I came across on our new wagg.it site.
It’s a custom application that will send email containing current external IP address to a specified email address automatically at set intervals.

Why do you need this?

I used to work as a network administrator at a company and had issues with DDNS (dynamic DNS) addresses where the domain name can change.
We used to use free DDNS services such as no-ip.com but this tool will allow you to bypass that and simply check your email to access your server. (Therefore keeping it even more secure…)

This can be great tool for embedded TCP/IP applications too.

What was that IP address again? How many times did you wish you had the IP of your crashing router on your home network to do a quick reset. I used to have a Linksys that would crash at least once a month at the most inopportune times and I designed this application to send me my network’s external IP address everyday or what ever intervals I wanted. Many ISPs with broadband give you a dynamic IP address and this helps you know that you are up and running and what the IP address is. It also is a nice monitor sending hourly emails for testing flaky connections. I have grown used to being able to view my external IP from my system tray and at the request of others with the same problems I created IP in Your Email application (don’t send me emails on the name).

Here’s a cool project that you can control your LCD with ethernet.

The simple “switch on/off a relay” circuit which was the only function provided by the avr web server until now did not require HTML-forms. I used simply 2 URLs http://baseurl/password/1 for switching on and http://baseurl/password/0 for switching off. This does not work anymore for the display as we want to type a text into a web page which should then be shown on the display. What is needed is a needed is a proper decoding of HTML form data.

Ah ha! Here’s a cool AVR LED Clock you can make that also syncs itself with the NTP
time server via ethernet! (We are going to have to make this too…)

Here’s a detailed instructions on building your own skype server for your home phone system.

One irritating feature of Skype is that it must be running on a computer for you to make and receive calls. That is, when your computer is off, Skype doesn’t work. Moreover, when you run Skype on the computer you use day in and day out, Skype’s performance (call quality, reliability and so forth) can suffer if you are doing other things that deprive it of the runtime resources it needs.

My solution was to build a Skype server that provides 24/7 phone service with the minimum of hassle and fuss. By dumping your regular phone company and taking back control of your home phone wiring using a Skype server, you will have not only a phone system with nearly the same capabilities as before-indeed, in some ways better-you will also save a bundle of money! In my case, I save a little less than $700 US each year (this year, next year, and the year after that, and so on), or about 82% off of my old phone bill.

Using a Skype server plugged in to the existing copper phone wiring of your home means that you can lift a receiver anywhere in your home, at any time, and get a regular dial tone. Incoming calls either from Skype users or regular phones ring all handsets throughout your home. Basically, you can make Skype behave like a regular phone line, but at a tiny fraction of the cost.

Here’s a cool ubuntu howto on a perfect server setup. Zedomax will eventually run on a ubuntu, well right now it’s running on fedora core 4 from aplus.net…

Yes, now we can go about 100 times faster I’d say since we are no longer sharing our website with bunch of other websites, we got own web server! It took 6 hours for me to move the site from shared host on bluehost.com to a dedicated server elsewhere.

Thanks to help from the tech support, I was able to troubleshoot the problem. When using phpMyAdmin to restore your Wordpress database, sometimes you will get errors if you try to restore the whole database with one file.

The best way I found was to take couple table at a time when backing up or “Exporting” from phpMyAdmin.

So if you are migrating to a new server and run into this problem, you will know what to do to fix it fast.

And then double-check that your tables are there and the number of items match with your older site.

UPDATE: If you are having trouble restoring your site, do not export wp_options table as this can cause lots of headaches. This happened to be the case with zedomax, which has lots of plugins…
NOTE: Please send any broken links (if there are any) to max@zedomax.com

Due to server update, there could be some missing stuff…

Thank you! Best Regards from all of us here.

Here’s a cool DIY on ethernet enabled servo motor control using CUBLOC CB220, XPORT, and Pololu Micro Serial Servo Controller by Thomas Edwards.

He also uses an Python Internet server to read the servo position information.

This was done in about 1 hour…pretty impressive.
