Passive power supply (PicoPSU clone) in HP Proliant MicroServer

Server messagesThe HP Proliant Microserver was a hit when it appeared on the market. Due to its capabilities it is still a perfect candidate for a low-cost SoHo server, NAS or HTPC. Most users who replaced the stock power supply had problems with the noisy fan and simply fitted a new 1U PSU or swapped the fan itself. For me this was not an option.
After a day of drilling, soldering, screwing and testing I am really happy to announce my next achievement: I successfully installed a passive 12V power supply instead of the stock one in a HP Proliant Microserver!

My passive beer can solar furnace

Do It YourselfIn the cold winter days the temperature in the storage building can fall below freezing point. I could use the spare electric oil heater I happen to have, but keeping it running for long months would cost a fortune. It did not take long until I found the famous passive soda can / beer can / pop can solar heaters / furnaces. This is just an other DIY, sharing my experiences during the building process.

Delphi 7 and Windows 10

Delphi 7I recently managed to crash my development machine so hard that not even a recovery was possible. After the OS the next thing to install was Delphi 7 and I had to face with the usual compatibility issues.
Had enough of researching, it's time to put all necessary steps at one place to make this 15-year-old software to work on a modern system, like Windows 10!

P400 battery repaired

Do It Yourself
Of course the salvaged battery had a shorted cell, so I had to improvise. The good news is that it's fixed and working! I also managed to reflash the BIOS with a non-official mod, enabling 3 Gbps, hot-swappable hard drives on all ports. Hail the high availability!

Small server outage for performance improvement

Server messages
Today I had to take the server offline to test a salvaged P400 RAID controller. Although the components were not in use for a really long time, a low battery charge seems to be the only issue so far. A SFF8484 to SATA cable is on the way to be able to harvest the advantages, which includes improved data transfer speeds (lower page load times) and complete data redundancy.

Windows Batch Scripting - Elevate.cmd

ScriptingI already made this mistake several times. UAC is turned on and I launch a Command Prompt to perform some activities. However, some actions will eventually fail as we don't have Administrative privileges.
In the past I launched a new Command Prompt (elevated, this time) and navigated back to the original folder to try again. Today I proudly present a script, which will do this for you!

Random outages

Server messagesRandom outages of all services were happening in the past two days. The reason behind is a failing UPS which has been temporarily bypassed until the issue has been resolved. Please keep in mind that until the faulty device has been replaced, even a short power outage will cause the system to reboot, resulting complete unavailability for a couple of minutes.
Thank you for your understanding, sorry for the inconvenience caused!

Scheduled power outage

server.jpgDue to renovations of the electric system, there will be a scheduled power outage from 2016.03.25 08:00 until 16:00 CET. During this period all devices will be turned off, which means the server and the website will be unreachable.
I am sorry about the inconvenience, thank you for your understanding!

Server outage

server.jpgDuring the upcoming weekend I am planning to move the server hosting my services to a different location, which will result inevitable outages. However I am glad to announce that the useable bandwidth will be increased by 100% and due to the completely different infrastructure I am expecting the availability to be increased as well.
Please be patient, everything should be back to normal until Monday, 15th of February.
