As you know Computer Dudes does its own research and development. For the last year we have been working on server solutions that use significantly less power and generate less heat.
We are now proud to announce our first line of Server Products under our brandname "Newline MicroServers".
The initial MicroServer is built with 8 Raspberry Pi 4Bs in a plexiglass case that smaller than a loaf of bread. We named it "Chico" because of its size. Chico is portable too when run off 5 volt USB power packs.
The first version is for office and datacenter use. New models will include additional features to allow them to be a security router, network scanning antivirus tool, WiFi extender or access point, advanced email server, live streaming audio-video server, and a whole lot more.
Additionally our servers are already setup to monitor and control factory machines and printing presses... just about any project with motors, sensors, and communications.
Now it is time to talk to some local and regional companies about reducing their Data Center power bills by 2/3rds with our Newline MicroServers.
Each Newline MicroServer has 8 processors and uses a maximum of 125 watts of power. Compared to eight standard rack mount servers that use up to 4000 Watts!
Be sure to check out the photo, it really is smaller than a loaf of bread. :)T

Today we invented a new "Mail-able" Computer that tracks itself as its being transported, measures radio channels, temperature, pressure, motion, speed and "calls home" when it finds an open network.
Sorry, it is proprietary technology and not for sale at this time, but maybe soon. - Todd ;)
A cluster of "Pi" offers new hope in decrypting Ransomware. A cluster of 4 Raspberry Pi 4B's we named "Chico" because it is smaller than a loaf of bread.on 15 Sep 2019 Posted by Administrator Category: Security News
Ransomware has become an annoying problem here in Florida and the Southeastern United States. Many small companies and government agencies are not prepared and have no defense against the attacks. They also have no money to get new computers or repair the security problems that let the Ransomware in.
Below are some of the things we are looking at in addition to Decryption Projects as well as how we plan to setup the cluster for maximum efficiency.
1) Already making mods to the original configuration. We found a Windows Utility that will Format an SDCard in FAT 32 up to 2 Tb. (far past the Microsoft limitation of 32Gb) We used the fastest Camera Grade SDCards we could find with 64 Gb each.so a 4 Pi cluster has 256 Gb of Solid State Camera Grade SDCards as its primary Hard Drive.
4) The WiFi and Bluetooth are great but for pure computing strength we will shut them both down and use the Gigabit Ethernet Port. Every un-needed driver, program, or function shut down and removed increases the computing power of the Raspberry Pi 3 and 4.
5) Next we will be shut down devices and functions not used to save computing and electric power. More on that here: https://learn.pi-supply.com/make/how-to-save-power-on-your-raspberry-pi/
6) Then we will setup a RAMdrive and set the software to load the RAMdrive from the SDcard and then booting from the RAMdrive. (Because it is much faster) https://www.domoticz.com/wiki/Setting_up_a_RAM_drive_on_Raspberry_Pi?
7) When the cluster is complete it can be used as a high speed webserver. In fact, the Raspberry Pi manufacturer uses a cluster of Pi's to host their website and support sites. Very heavy, interactive websites with all sorts of multimedia too. https://www.techrepublic.com/article/low-cost-raspberry-pi-4-cluster-hosts-official-pi-website-handles-record-traffic-for-pi-4-launch/
Update for Monday, September 16, 2019
Today we reviewed memory device speed for the Raspberry 4B.
USB 3.0 vs MicroSD Storage
Since Raspberry Pi 4 now comes with two USB 3.0 ports, which support ~100MB/s read/write speed, Connecting a SSD USB 3.0 Drive gets even better speed..
But before you settle on one of those devices check out the transfer speed of the DDR4 on the Raspberry Pi 4.

Update for the Week of October 7th, 2019
The first successful field test was conducted at an office building and residence near downtown Tallahassee, Florida.
We boosted Chico's Hardware configuration up to 7 Raspberry Pi 4B's and we had to order a cable to add the 8th one NEXT week.
The onside tests were successful. No problems with heat, power, batteries or networking.
Next Week we are going to work on the clustering and ramdisk to increase the speed of all operations.
More soon. - Todd :)
