      Current state of vpsBoard   02/04/2017

      Dear vpsBoard members and guests:

      Over the last year or two vpsBoard activity and traffic has dwindled. I have had a change of career and interests, and as such am no longer an active member of the web hosting industry.

      Due to time constraints and new interests I no longer wish to continue to maintain vpsBoard. The web site will remain only as an archive to preserve and showcase some of the great material, guides, and industry news that has been generated by members, some of which I remain in contact to this very day and now regard as personal friends.

      I want to thank all of our members who helped make vpsBoard the fastest growing industry forum. In it's prime it was an active and ripe source of activity, news, guides and just general off-topic banter and fun.

      I wish all members and guests the very best, whether it be with your business or your personal projects.

  1. The revision 1.2 of the Raspberry Pi 2 has now a BCM2837 CPU with up to 900 MHz and includes 1 GB RAM. Looking at the Raspberry Pi 3 with it's 1.2 GHz, the main difference between them is the the WiFi and Bluetooth module. Some might think that this is a stupid idea, but their are some advantages: RP2 on the same 64bit plattform RP2 with the same amount of RAM RP3 as an upgrade if someone needs Wifi and/or Blueooth (and UART issues) For me the Raspberry Pi 3 had two major issues: Heat - looks like the > 1 Ghz need active cooling First on 64 bit - not that good for software support Both checked with the new revision of the Raspberry Pi 2.
  2. I am using Armbian for my head-less servers. Currently this setup is running on a Raspberry Pi 1, a Raspberry Pi 2 and a Olimex A20-OLinuXino-LIME. Installation is quite simple.

  4. I know we have guys with Pi's and wide interests. With the holidays, some of us actually get some peace and quiet, and it's a great time to get that idle gear you bought this year doing something useful. Raspberry Pi's are probably sitting around unused by many of us, so I thought why not promote getting them doing something . Nice little devices, with the right software. So, we all know Pi's can run Kodi and related AV TV zombie causing tasks. Blah. There is other stuff, that's what we want here. Ready to download to copy to SD card and BOOM the Pi becomes useful. Accepting recommendations from others to append to this list.

  8. Well, I've been putting it off for too long and had to jump on the Raspberry Pi after this Reddit article resparked my interest in it: http://www.reddit.com/r/AskReddit/comments/1f607z/owners_of_a_raspberry_pi_what_do_you_use_it_for/ Some really awesome examples of just what this tiny device can be used for. Twenty minutes and a few clicks later, I should have my Pi here tomorrow. Thanks Amazon Prime! Curious what everyone here uses their Raspberry Pi for.

  12. This is the fourth part of my RaspberryPi tutorial series. You can find the first part You can find the second part You can find the third part We now add some additional GPIOs to the Raspberry Pi: The Raspberry Pi does have a limited number of GPIO (General-purpose input/output) pins. If you want to support more LEDs/buttons or other components you can easily get out of pings. But the Raspberry Pi is supporting I2C (Inter-Integrated Circuit) bus which allowes to connect integrated circuits with only two pins. We will now add a MCP23017 chip as an I/O expander to our Raspberry Pi. 1. Enable I2C bus sudo nano /etc/modules Uncomment following lines: i2c-bcm2708 i2c-dev sudo nano /etc/modprobe.d/raspi-blacklist.conf Comment the blacklist entries #blacklist spi-bcm2708 #blacklist i2c-bcm2708 2. Install i2c tools sudo apt-get install i2c-tools 3. Connect the I/O port expander to the Raspberry Pi If you look at the chip its pins are numbered from the top left: The first pin is marked with a small dot. Connect pins 9 and 18 to power (3v3) Connect pin 10 to ground Connect pins 15, 16 and 17 to ground They are used to configure the I2C address - so if you have a chip with a fixed I2C address you can change the one of the expander Connect pin 12 to SCL Connect pin 13 to SDA 4. Search for the address of the I2C component sudo i2cdetect -y 1 The "y" parameter will set the number of the I2C bus. The latest revision of the Raspberry Pi is using the address "1". Older version use the address "0". Output will be: 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: 20 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- 5. Work with the I2C port expander So we now know that we have to use the bus number "1" and the address "0x20". The expander does have two "banks" of GPIO pins. They are named "GPA" and "GPB". "GPA0-8" does have the address "0x13". "GPB0-8" does have the address "0x14". Each bank does have 8 ports. A byte is used to code the address of each port. So we have to think in bits to know which port is enabled: Activate GPB0: 0x01 Activate GPB1: 0x02 Activate GPB0 and GPB 3: 0x07 A byte looks like this: 00000000 If we want to call the first pin we have to set the address to: 00000001 which is 1 in decimal If we want to call the first pin and the second pin we have to set the address to: 00000011 which is 3 in decimal Only thing we have to do is to convert the bit numbers to decimal numbers. So if we want to activate GPB0 and GPB 3 we have the bit number 1001 which is 7 in decimal. The format of the ic2tools is: i2cset -y [bus] [I2C Address] [Target] [Value] Example: i2cset -y 1 0x20 0x01 0x00 Like any other GPIO pins you have to set the direction. So you have to tell the expander if you want to write or read values to the GPIO pins. This can be done with the addresses "0x00" and "0x01". Bank A output i2cset -y 1 0x20 0x00 0x00 Bank B input i2cset -y 1 0x20 0x01 0x01 If you set the value to "0x00" the GPIO bank is set to output - e.g. used to blink LEDs. If you set the value to "0x01" the GPIO bank is set to input - e.g. used to read state of buttons or switches. Example to light up two LEDs connected to port GPB0 and GPB2: #Set Bank B to output i2cset -y 1 0x20 0x01 0x00 #Set Bank B value to decimal 5 to activate ports #0 and #2 i2cset -y 1 0x20 0x14 0x05 That's it. We can now use the port expander to work with 16 additional GPIO pins.

  15. We have a new product - a Raspberry Pi based servers. Our internal development and testing is complete, now I need two external beta testers. The two beta testers should be respected community members and should test the service for some time and report any problems they find directly to me. The two beta testers will receive 50% discount for life (or as long as they want to keep the server). Our standard 7 day money back guarantee applies too. Please PM me if you are interested. Now about the offer: It's a server based on a Raspberry Pi - a 700MHz ARM processor, 512MB RAM (usable about 490MB), 32GB USB storage (usable about 29GB). The features include remote power control, automatic reinstalls from the client area and rescue mode. Each server comes with one IPv4 address. IPv6 (/64) is available on request. The regular price for the service will be $10/month (+20% VAT for the poor souls from the EU). This is the order link - https://www.fitvps.com/members/cart.php?a=add&pid=35 However PLEASE DO NOT ORDER THIS BEFORE CONTACTING ME. We don't have stock. Only the two beta testers can order this, after contacting me and i will give them the discount code for 50% off for life.
