    Patcher got a reaction from Wolf2000 in For our get all the data fre..ks :)   
    Well i know some of u like to watch data .....
     
    Came allong this git, and is pritty awesome 2
     
    check it out here: http://netdata.firehol.org/
     
    Worx fine on a bana-armbian (if moderators dont like gifs just remove it np)
     

     
     
    Edit: tweaks for embedded devices
    Running netdata in embedded devices
    Embedded devices usually have very limited RAM resources available.
    There are 2 settings for you to tweak:
    update every, which controls the data collection frequency
    history, which controls the size of the database in RAM
    By default update every = 1 and history = 3600. This gives you an hour of data with per second updates.
    If you set update every = 2 and history = 1800, you will still have an hour of data, but collected once every 2 seconds. This will cut in half both CPU and RAM resources consumed by netdata.
    You can also disable plugins you don't need. Disabling the plugins will also free both CPU and RAM resources.

    Patcher got a reaction from petrmaje in Lamobo R-1 Sata power   
    Nothing to add, just a breadboard a 4.7K res on a base of a transistor (picture TKasier) and that  petrmaje didn't give up on the R1, makes me smile.  
    I geuss Goethe is right again : "In the realm of ideas everything depends on enthusiasm... in the real world all rests on perseverance." 
     
    Currently i´am on a D.V.R. with R1 and zoneminder (ipcamera) project, no problems, and damn the A20 still keeps surprising me.

    The whole idea is crap. The person supplying additional power used the wrong Micro-USB connector (USB OTG and not power-in).
     
    You always have to keep in mind that this is not a Raspberry Pi (where you can insert power easily through GPIO pins since its power scheme is totally different) but an A20/AXP209 device. And the PMU (AXP209) decides on its own where to take power from if there is more than one source available.
     
    In case you use kernel 3.4 I would suggest installing RPi-Monitor with the sunxi fixes since this immediately shows you thermal values for SoC and PMU and the power used from the three different available sources (power-in, USB-OTG and LiPo -- for the latter not exactly when you connect a PSU to the LiPo connector since the voltage can't be read out and my sunxi fixes then assume 5V).
     
    I delivered one R1 recently to a customer. Runs vertical, no heat sinks (one on the SoC but a crappy one that doesn't help at all) but some sort of convection and a small fan that jumps in if the PSU's temperature exceeds 55°C. Uptime while being totally stable for 30+ days. Temperature was a problem a few weeks ago when ambient temperature exceeded 30°C (since inside the enclosure it were 7°-8° above and then the PMU's temperature exceeded 55° -- might be ok if it gets higher but I decided to let then a fan cool down both SoC and PMU since the fan is just a few cm above both)

    :-) I was in the same situation several months before. Lamobo can work perfectly, as both of my lamobo does, but you must: (thanks to Igor, Patcher, Tkaiser etc...)
     
    - Operate Lamobo verticaly
    - put high profile heatsink to BCM switch (under the harddisk)
    - put heatsink to A20
     
    If you use ordinary HDD with consumption 500mA, no USB, no WiFi, no HDMI and you have good USB power cable, you don´t need secondary power via battery connector.
     

     
    :-) It works )))

    FYI: Running the very same test (" cd /mnt/sda/ && stress -t 900 -c 2 -m 2 -i 2 -d 2"), first time with the R1 being powered through the LiPo connector and second run through the crappy Micro-USB power-in (consumption peaks and voltage drops down to 4.7V -- the PSU provides 5.0V and with just 20 cm cable and Micro-USB we loose between 0.1-0.3V idle/load)

    Patcher got a reaction from petrmaje in R1 overheated?   
    Hi petrmaje
     
    With my farmer logic its probly your Broadcom BCM53125 chip that sits right under your HDD.
    Your prbly dont have a HDD attached that funktions (@here) as a very luxury cooling plate with additional data parking space.
     
    My sollution :
     
    If your using the standard acrlyc housing loose the sides and put it verticaly like tkaiser said. There is enough space between the acrylic housing backplate to fit in a small cooling element/plate. Always cool the A20 but thats not the problem imho. Well i dont have it build like Tkasier but its realy stable 2 altough i might paint it black 2
     
    see pictures
     
    loose the side panels
     
    cool your BCM53125 chip

    FIRST OF THX iGOR FOR YOUR GREAT WORK AND HANDS-ON WORKING IMAGES
     
    Sata powering, no nonsense, just inject the power 5 Volt into the LiPo battery connector and your ready to go.
    Its idd poorly designed, and there are different solutions about, this 1 suits me fine.
     
    I found the solution on a forum, if i find it again ill post the 1 who came with this solution. Credits due to that person who experimented, without risking his/your warranty.
    The battery charger will shut off above 4,2 volts, and i was not using it anyway.
     
    Because of another design flaw, watch the temperature of your hard-disk, its 40+ because it sits on top of something hot.
    Especially if your using the closed acrylic case that comes with it.
     
    Besides the hardware/design flaws in this board it will make a kick-ass router.
     
    Edit: after injecting the 5 Volt to the LiPo socket press power on button
