After the hack attempt occured some months ago, we lost many of forum messages. Most old messages was lost and couldn't be restored from backups... because backups was also corrupted. That was really dissapointing to many of us... so i was searching a way to retrieve these messages. Finally after hard work with old databases we managed to make this work... I am happy to announce that the majority of old posts are restored We have back most of messages and you can search again your old posts If you notice any problem, don't hesitate to contact me..

There was a code injection hack on the site yesterday. I have cleaned the files and I have taken protection measures. Now everything should be ok. I am sorry for any trouble it may caused. Please report any problem you may notice browsing the site.

The forum is back to normal after fresh installation and a little bit of securing. Thanks for your understanding and support on this issue. As for internet explorer "not responding", seems a local problem to me. What version of ie do you use?

Hackers hit the forum and injected malicious code on some files. I have cleaned forum files and everything seems to be safe now. Soon Electronics-Lab.com site will be marked as safe from Firefox. Did you still experience delay when typing?

Problem fixed, please try again.

That's true Hero999. After database examination i see that message body of all posts before 24 Jan 09 are replaced with "

Maybe deleted by a moderator for a reason or for posting in wrong board. Feel free to post it again.

Last days there was a problem on server that caused slow response. Today the site loads really fast as checked from my end. Do you still have problem accessing the site?

There was a problem with server last days. I am trying for the best resolution. Thanks for your patience.

That's true, i have to remove the ebooks. Sorry, but there was no other way.

Illegal content (ebook/magazines/software) will be deleted without any notice. Thanks

The photos on the project page here in Electronics lab are with the 10K resistors. I agree that are high and i should test a lower value. About the collector resistors these are calculated to produce a white color when all leds are on. That means that we don't need all led to power on maximum. Some of them will be used below specifications to achieve better efficiency on the produced colors.

I think that a Power Electronics board is a good idea. So i moved on creating such a board. You can find it here: http://www.electronics-lab.com/forum/index.php?board=33.0 Thanks Gazza for the idea!

Hi you can find cheap 2x16 LCD here: http://home.exetel.com.au/marknac/displays.htm He sells 13$ each

I think that the reason is that the main advantages of SMPS are underutilized in such applications. That means that we don't need a high cost and difficult to design PSU for a home audio amplifier that powers from mains voltage and has a noticeable volume, nor on a lab power supply. Having efficient of 70-80% and up doesn't offer much in these applications (instead offer much in battery powered applications). Among all these parameters, we add the non existed problem (on linear psu) of EMI/RFI emmitions that can be attenuated using filters and shields but can't be eliminated. In many cases the switching frequency is in audio spectrum or a little above and that makes the problem more complicated. So, we gain more than we loose not using SMPS in such applications. That's the reason!

;D ;D ;D Thanks all of you ;D ;D ;D That's true! Today i become 24 (that's a nice number!) and i feel really lucky receiving greetings from all of you! I will try to do my best and wish peace and creativity to all nice people like you!

Ok, then. Here is the new Moderator's board: http://www.electronics-lab.com/forum/index.php?board=32.0 Hope this to take us a step further in communication. Mike

Steven, maybe the topic was moved/removed from original location for a reason in the meanwhile (until you read the email) and for that's why you couldn't find it. Also, please give a try again to contact audioguru and report back. I didn't undertand what was the problem contacting audioguru.

I am confirming that site was hacked today due to a security hole. Appropriate measurements taken to avoid future problems. Hacker's ip adress reported for abuse and blacklisted. Forum attachemnts affected and hope to restore them from backup as soon as possible. Thanks for your understunding.

Hi Ante Upload capability has do to with many things as your internet connection speed (becuase the time thershold is limited). I have tryed to make some arrangements on the server's settings, hoping to solve those problems. Please make some test uploads now.
