1. die feit dat 'n PC maklik 300 Watt tot 600 Watt op "Base load" bytel, waat die Raspberry Pi slegs 2 Watt (Twee watt) gebruik om dieselfde taak te doen.

As jy Windows en 'n PC verkies (wat jy vir ander doeleindes ook kan gebruik) kan jy altyd kyk na iets soos die VivoMini - hulle gebruik ongeveer 7W as hulle idle.  Om inverters te monitor kwalifiseer basies as idle - daar is net nou en dan bietjie CPU activity.  Ek gebruik 'n UN42, dis 'n fantastiese stukkie ingenieursvernuf in 'n besonderse klein pakkie...

Dit is nou ʼn stukkie goeie advies. Ek gaan dit so bietjie ondersoek

Nou ja, met die website crash en die 2 dae oue backup wat restore is, het daar so paar posts verlore geraak...

Een van hulle is waar @fritserasmus gevra het of dit hierdie een is: https://www.webantics.com/asus-vivomini-un65h-i3-6100u-ultra-compact-windows-pc vir R7500, wel dit is nie hierdie een nie, maar een van sy voorgangers wat my destyds net onder die R1500 gekos het: https://www.webantics.com/asus-vivomini-un42-m023m-ultra-compact-barebone-pc-kit, maar hulle is blykbaar nie meer beskikbaar nie en ek sou nie R7500 betaal het net om die inverter te monitor nie. As jy hom vir 'n ander doel ook gaan gebruik kan dit dalk die koste regverdig.

En dan is daar nie net Windows Tablets vir +-R1500, maar ook Windows PC Sticks.

En hierdie: http://cloudgate.co.za/

Some bloody nice small devices coming out lately. Why are they so expensive I wonder?

The thing that caught my attention way back, with prices around R1500 - R1800, all in one device that has a screen, a battery built in, WiFi built in, onscreen kbd mouse, using the same power as a Pi if the screen is off, especially when I also get a built in camera to point to the devices that I can view them remotely (if I want), made tablets a no-brainer for me.

You simply cannot get a Pi setup at that price range: Pi + PSU + SD card + case + fan + UPS = easily over R2k.
Then you add a bigger external HDD, price goes up further.

Any case, use it don't, each to our own personal convictions, I am all for small tablets / Pc Sticks.

Pi, approximately R700. PSU, R130. SD-card, 60 bucks. Case, R120. Fan, what for? External HDD? We're not downloading movies here. UPS, run from inverter output, or get a DC-DC converter and run it from the batteries. IF you don't need an LCD you cannot really beat the Pi (Pishop has the Pi-zero now for under R100!). If you need the LCD, then the cheap tablets on the market make compelling arguments for your money.

.. what for?

From the post on the forum over time with people asking for help, using the Pi's more.

Fans for when Pi's overheated due to where they where installed.
HDD when they are used from more than just data reading, but also for downloading things - made a lot of sense.
UPS for where they got damaged / SD card got damaged, when inverters switched of under excessive loads.
Or when people forgot the Pi was on when they switched off the inverter.

Tablets can also overheat, especially if the CPU run high constantly and battery / charger can't keep up.

Tablet have limited space as well, the cheaper ones much less than the nicer, and more expensive ones. So a HDD + added USB OTG adapter would be needed to download things

I guess a UPS would be nice to have on a tablet as wellm especially after the battery stops working after 4, or so, years?

 

With mine, the solar app recording data does not affect the CPU. Even with other tasks, the small CPU idles. Wifi works lekker, one less wire.

The 32gig hdd I have has 14gigs spare for "files" so every morning I copy them "files" over to the QNAP for "use" later. Portable USB HDD is an option, quicker to copy large files than via Wifi, for I have a 7 port non-powered USB hub connecting to said tablet to get to the 6 devices and HDD connected.

As the tablet runs 24/7 off the 220v from inverter, the batt may last a long while and like with a laptop, towards batts end, if it just keeps it going got a few minutes to shutdown thereafter, one can get another year of so out of it? Once the batt goes, use it till the screen fails or HDD packs up or whatever happens. I recon 5 years easy.

 

I tell you, I don't understand how people manage to overheat an Rpi. It must be working in some seriously hostile environment or something. I've worked on three of these SBC things now, the CCGX (which is an ARM Cortex A8 Texas Instruments thing under the skin), the Beaglebone, and the Rpi. They don't need fans.

Was here on the forum that the problem surfaced. 

Think the one Pi was in a cupboard with the inverter if memory serves. No other option or place to install it.

Yeah, I remember that... that's ONE data point. I have 200 of these things in the field and the only thing that fails is the sd-cards.
