Mikro računari raznih marki kako firmirani tako i oni bezimeni imaju svoje dobre i loše strane pa koliko para toliko i muzike...
Naravno u tom segmentu HP sada to več nije novi računar izdvojio se jedan mališan koji itekako dosta pruža i daje za svakodnevni rad.
Šta ga to izdvaja od drugih pre svega malih je dimenzija - male težine svega 1,7 Kg i naravno mala potršnja pod punim opterečenjem svega 75 wati - što u praksi znači jačine jedne klasične sijalice potrebna mu je snaga za rad.
Od ostalog ne manjka mu ni smeštajnog prostora za SSD a pored SSD-a takođe postoji i još jedan adut ovog mališana a to je Solid State Drive with NAND Flash and SATA interface.Tako da to praktično znači imate ovog mališana u SSF - faktor formatu sa recimo jednim hard SSD - diskom od 1 TB i naravno uporedo još Solid State Drive with NAND Flash and SATA interface takođe sa još 512 Gb do 1 TB brzog NAND drajva.
Naravno u sebi ima dva utora za maksimalnih 34 Gb - memorije ali u praski ide makisimalno 2x16 Gb SODIMM DDR-4 memorije što je više nego dovoljno.
Mališan koji sve to objedinjava u sebi je HP EliteDesk 800 G2 Desktop Mini Business PC.
To je računar iz 2015 godine sa procesorom Intel i5 6500T nominalne snage od 35 wati.Sam procesor je 6 generacije i radnog takta od 3,2 do 3,6 GHz.
Video memorija se uzima od sistemske ram memorije i u zavisnosti od sistema može da bude do 4 Gb.
Sve u svemu jako odličan računar idealan za tamo gde nema prostora sa solidnim procesorom a podržava intel i7 6700T radnog takta od 2,8 do 3,6 GHz.
Imperativ operativnog sistema na njemu je jedino Linux - distro o onom drugom ne trošim reči.
Tako ko može da nabavi ovog mališana odličan je deal napravio u svakom pogledu.

As ARM continues to make inroads in the personal computing space thanks to its more modern and streamlined instruction set architecture (ISA) and its reduced power demands especially compared to x86 machines, the main reason it continues to become more widespread is how easy it is to get a license to make chips using this ISA. It’s still not a fully open source instruction set, though, so if you want something even more easily accessible than ARM you’ll need to find something like these chips running the fully open-source RISC-V ISA and possibly put them to work in a custom supercluster.

[bitluni] recently acquired a large number of CH32V003 microcontrollers and managed to configure them all to work together in a cluster. The entire array is only $2 (not including all of the other components attached to the board) so a cluster of arbitrary size is potentially possible. [bitluni] built a four-layer PCB for this project with an 8-bit bus so the microcontrollers can communicate with each other. Each chip has its own ADC and I/O that are wired to a set of GPIO pins on the sides of the board. The build is rounded out with a USB interface for programming and power.

There were a few quirks to get this supercluster up and running, including some issues with the way the reset and debug pins work on these specific microcontrollers. With some bugs like this out of the way, the entire cluster is up and running, and [bitluni] hints that his design could be easily interfaced with even larger RISC-V superclusters. As for a use for this build, sometimes clusters like these are built just to build them, but since the I/O and ADCs are accessible in theory this cluster could do anything a larger microcontroller might be able to do, only at a much lower price.

After the Orange Pi received a RAM upgrade just a few days ago, the Orange Pi 3 H6 is now a new version of the single-board computer. The Orange Pi 3 H6 is always equipped with an Allwinner H6 SoC with four A53 cores clocked at up to 1.8 GHz. Depending on the model variant, there is also one or two gigabytes of LPDDR3 RAM, with the versions being available with and without eight gigabytes of eMMC flash memory. The rest of the equipment is the same for all variants. An HDMI and CVBS output is installed, and a 3.5 millimeter jack allows audio signals to be output. The connection to a network is either via Gigabit Ethernet or via WiFi 802.11 a/b/g/n/ac, whereby the module also supports Bluetooth 5.0. Four USB 3.0 and one USB 2.0 ports allow external devices to be connected, and an IR receiver can also be used to operate the Orange Pi 3 H with a corresponding remote control if desired. Typical for development boards: The GPIO panel, equipped with 26 pins, allows the connection of sensors and actuators. The 90 x 64 millimeter board can be expanded with a PCIe card and, according to the manufacturer, supports Android 7.0, Ubuntu and Debian. The four model variants are now available for 30 and 35 US dollars with one or two gigabytes of RAM, respectively, with eMMC memory 35 and 40 dollars are called.

Orange Pi 5: New alternative to the Raspberry Pi starts with up to 32 gigabytes of RAM.
The Orange Pi 5 is a currently announced single-board computer, which - the name already suggests it - takes an example from the popular Raspberry Pi (affiliate link) and should therefore also be used to implement your own projects. The Orange Pi 5 can also be used as a desktop system or as a media server, but numerous connections that are particularly relevant for makers are built in - 26 pins are available for connecting sensors and actuators, with UART, PWM and CAN being supported, among other things becomes. Cameras can be connected not only via USB, but also via MIPI CSI, and two MIPI D-PHY connections are also installed for connecting screens. Conventional screens can be connected via HDMI and DisplayPort (via USB Type C). An RK3588S with four Cortex A76 and Cortex A55 cores is used as the SoC, an ARM Mali-G610 MP graphics solution and an NPU with a performance of 6 TOPS are installed. Depending on the configuration, the main memory is 4, 8, 16 or 32 gigabytes. In contrast to the Raspberry Pi, the Orange Pi always comes with a 32 gigabyte eMMC memory, a microSD card slot is built in. A USB 3.0 and a USB 2.0 port are available for connecting standard accessories. A single Gigabit Ethernet port is available for connecting to a network, the built-in AP6275P module supports WiFi 802.11 a/b/g/n/ac/ax and Bluetooth 5.0. The supply of electrical energy is possible with a round plug and five volts as well as via USB type C using the USB PD 3.0 protocol. There is currently no information on the exact date or price.

Orange Pi 5: An alternative to the Raspberry Pi will soon be available with 8K support, PCIe and costs well under 100 euros.

The Orange Pi 5 was announced months ago and now has a price and a date too. The model should be on the market in December and the version with four gigabytes of RAM should be available at a price of just under 72 euros. This information applies to direct imports from the Far East. The import duties should already be included in the price. The Orange Pi 5 is already listed on Amazon, at least in the USA. The predecessors of the Orange Pi 5 are not available from typical mail order companies in this country. The Rockchip RK3588S is used as the SoC in the Orange Pi 5. The Rockchip RK3588S is a trimmed and cheaper version of the Rockchip RK3588. The chip also has four Cortex A76 and Cortex A55 cores and supports real-time decoding of H.265 and H.264 material with 8K resolution and up to 60 frames per second. Consequently, the Orange Pi 5 also comes with an HDMI 2.1 interface, which also supports image output with such a high resolution. Depending on the model variant, the main memory measures four or eight gigabytes. In contrast to the Raspberry Pi (affiliate link), the Orange Pi 5 comes with a PCIe port that allows the installation of an NVMe SSD in M.2 2240 format. The PCIe slot of the 100 x 62 millimeter board corresponds to the PCIe 2.0 standard. In addition to a Gigabit Ethernet port, there are also several USB ports and dedicated ports for cameras and LCD screens. Sensors and actuators can be connected using the 26-pin pin strip.

Ovaj Orange Pi 5 ce biti odlican, Raspberry je postao bezobrazno skup.
Tacno El Comandante sve sto je ali uslovno do 100 dolara a tu mislim na ceo kit je pristojna cena.
Ali naglasavam ceo kit - kuciste - napajanje - eventualno wi-fi antena itd.
Da ima veliki broj ovih malih micro racunara ali je cena jako visoka a onda sve gubi smisao koncepta ovih malih masina jer sve ostalo je politika i interes.
Male dimenzije - mala potrosnja - relativno dobra prosirivost periferijama - solidan CPU i GPU a onda primeni i mogucnostima nema kraja.
Moj ugao gledanja na stvari je prevashodno Linux - odnosno sve sto je Open Source jer tu vidim datu svrsishodnost malih racunara a opet sve to objedinjeno Linuxom kao operativnim sistemom.
Pa sa tim u vezi dajem jedan primer cisto informativnog karaktera.
Tako da kada ste slobodni pogledajte glavnu stranicu klikom na linku ovde:https://www.asrockind.com/en-gb/
A onda moj favorit cisto radi nekog poredjenja on je na linku dole:

E sada sve ovo je fatasticno ali je bezobrazno skupo - mozda jedan od razloga lezi i kvalitetu za industrijski standard i specifikacije.
Ali sa druge strane a tu mislim prevashodno na FOSS je kombinacija nema im kraja.

Sada za neki svoj projekat ili DYI moze da posluzi i ovo znam nije nista specjalno ali probao sam Sparky Linux na ovom radi odlicno mala potrosnja male dimenzije kada se sve dotera radi ko Svajcarski sat.
Ja nisam koristio originalno kuciste ves sam upotrebio jedno od home cinema ricivera posto je slim i desktop - napajanje od 12V - snage 3A.
Jedino prosirenje koje sam uradio je SSD umesto HDD-a i 8Gb rama.
Licno sam zadovoljan jer kao sto rekoh Sparky je odlicno koncipriran za neke ovakve stvari.
A tu je El Comandante bio u pravu bezobrazno skupe.
To je link o tome sta sam upotrebio za samogradnju kao jedan od predloga.
Zadnja varijanta ovog klijenta je na linku:https://cdn-reichelt.de/documents/datenblatt/E200/IGEL_IZ3UD3_DB-DE.pdf

E sada drugari sa FOSS - a imam jednu informativnu poslasticu za vas radi se o AMR CPU gde jedna konfiguracija ima 96 odnosno 128 core stvarnih.
No da ne prepricavam postavicu vam link pa pogledajte primena video editing - rendering - cad - cam programi - graficki dizajn - muzicka produkcija itd.
Ampere Altra zapamtite ovo ime bice sve prisutnije u pogledu ovakvih racunara u buducnosti.

Odlična zamena za Raspberry pi sa mnogo jačim tehničkim karakteristikama i hardwerom.
Ono što je važno je da košta upola manje od pomenutog Raspberry pi sa cenom od 64 dolara.


Drugi je SBC.

AML-S905X-CC (Le Potato) 2GB.​

Libre Computer Board AML-S905X-CC (Le Potato) 2GB 64-bit Mini Computer for 4K Media.​

Sa 2 Gb rama ali je cena jako pristojna svega 35 dolara.

Tehnicka podrska.
Dobih ovih dana jedan Lenovo Idea Tab 100S.
Nista specjalno sa sadasnjim tehnickih karakteristika savremenih laptopova i netbook-a.
Na pomenutom racunaru je bio instalisan win 10 u 32 bitnoj verziji.
Ali na jednom od egzoticnih jezika vlasnik je to hteo da reinstalira sa novom svezom instalacijom ali kada je to krenuo da radi a desava se nestalo je struje.Onda je naravno pokusao ponovo da pokrene install ali bezuspesno.E onda je taj lenovo dosao kod mene.Sta sam uradio napravio sam boot usb sa Sparky Linuxom i uspeo da pokrenem instalaciju ali pri samom kraju iste sistem me obavesti da je doslo do boot error odnosno da nesto nije u redu sa grubom.U live Sparky linux radi bez problema ali install ne ide.Od alata tu su Ubcd i jos par analognih softwerskih alata.Mene zanima vase misljenje kako resiti dati problem.Sam spomenuti Lenovo Idea pad 100s nema hdd vec MMS od 32 Gb i 2 gb rama.A takodje i jedan slot za SD karticu.Da li od linux distroa postoji nesto specjalizovano sto moze da resi problem a ako ne voleo bih cuti vas komentar na sve ovo.Meni je problem interesantan jer ne moze pokrenuti windows install a pokrece linux pa bih ovo da resim uz vasu neku sugestiju a verovatno je mozda kazem i bilo slicnih pitanja u proslosti.
Unapred hvala svima na odgovorima.
