Re: [PLUG] Backup RPi SD card

[Chuck Hast]

Tomás
Sorry I should have got  back on and told you I found it, but the charge
rate
is only 1.5 amp, the other unit is 2.0 amp. The RPi doing the WeeWx stuff
pulls data every 60 seconds, writes to the DB and then sends it out to WU,
CWOP and Findu.com. When it does that it pulls a wee bit more current
that usual. So I am going to give the other unit a try as I have the PSU for
it. I will also power the Acurite console off of it.  If this works I have
a whole
boat load of places I am going to do that trick. Indeed if we do not move
out
of this place, I am going to put an RPi up on the  ridge above the house
with
a AT LTE modem on it, AT has an offer of 250GB/mo @ $60/mo or 500
GB/mo @ $100/mo. They just came out with the offer last month, it is
directed
at some states back east, but people are calling and getting the offering
every-
where they have put in LTE. At this time I have 50GB @ $110/mo with Hughes
net, and they suck royally. So I can put an RPi up on the ridge and run
about
500ft of fibre down to the house let the RPi handle the cell modem and get
rid of Hughesnet. Whattavampire they are. That one I will power with the
"kludge" as it will be a much better option there. May even try some solar
to see how much the batteries will keep up that way. Use an RPi to monitor
that too.

If I get the job I am angling for I will not need to worry about it, but I
can
always find something for an RPi to do.

Re: [PLUG] monitor drops to lower resolution after OS upgrade

[Tom]

Hi Randall,
I am glad that you got your graphix card working.
Would you be able to share what you had to do for the old HD 5450 to
get it working?
I have unused laptop which I would like to donate to a friend and I
believe that it has the same graphics card HD 5430/5450/5470. I will be
reinstalling it to 42.2 this or next week before handing it over, and
your experience could save me time researching the same issue.
Thank you, Tomas

Re: [PLUG] Backup RPi SD card

[Tom]

Follow the second link, scroll down to product description about half
way through the page, and check the Duo-Charge Section:
 Product description

 








  












  

   

  

  



 Offer Type:19200mAH

  
  


  

  




 
   
 

 
  
 
   

 




TeckNet PowerTitan T2 19200mAH External Battery:
Save time when charging! 

.
.
.
Duo-Charge:
The Duo-Charge function enables charging of the PowerTitan while it
recharges a connected device such as an iPhone or iPad.
 ...
Besides the battery capacity, there does not seem to be functional
difference between the chargers. Either of them should keep mostly idle
RPi running for at close to a day. I have 6500mAh USB charger running
RPi + PWM hat + WiFi dongle + a few sensors on a robot cart for about 8
-9-hours straight. The Pi lasts much longer than the other battery pack
feeding the motors.
I should have mentioned it in my original post, I thought that it is
obvious:
If your RPi consumes close to or more than the charging current max 2A
(depending on your actual power supply) - about 10% to power the
charger = ~1800mA --> your battery pack will not recharge after the
outage. In such case you would have to come up with different UPS
solution.
Best luck, Tomas

Re: [PLUG] Backup RPi SD card

[Chuck Hast]

Nat,
I have a kludge system that i am going to use until the passthrough charger/
battery arrives. It is ugly and being a kludge it is just a gell cell and a
power
supply, the battery is floating on the PSU. On power loss it picks up the
load
on the USB ports.

Re: [PLUG] Backup RPi SD card

[Chuck Hast]

Tomas,
The second selection looks more like what I am looking for but the first one
will certainly work. But I do not see mention of pass through charging or
charge while charging.

Went ahead and bought the first selection.

Re: [PLUG] Backup RPi SD card

[Nat Taylor]

I use something like that second battery to power my pi, it's just a cell
phone charger, I'm not sure what running it while plugged in does to it's
life.   One could put it on a timer so the power cuts, it drains the
battery for a while, then charges back up if that was advantageous for
battery life...

Re: [PLUG] Backup RPi SD card

[Tom]

There are probably other USB power banks which can be charged and
discharged together. Here are two examples:
https://www.amazon.com/TeckNet-Universal-16750mAh-Output-PowerZen/dp/B0
0FAU7ZB2/ref=pd_cp_107_1?_encoding=UTF8_rd_i=B00FAU7ZB2_rd_r=0JMM
HXMXK7RYWY9K361K_rd_w=712hM_rd_wg=6mOCV=1=0JMMHXMXK7RY

nology/dp/B01B534D4Y/ref=sr_1_1?s=wireless=5713662011=UTF8=1
491729627=1-1
Based on recommendation from this guy: 
http://raspi-ups.appspot.com/en/index.jsp He used older model which is
no longer available.
I wonder how smart is the circuit in avoiding the charge/discharge
battery cycles when the power is on - it relates to the battery life.
