Hello There,

I hope this is not taken as too much of an ad - but i thought this forum might fit well for our project.
We are a software company who uses the raspberry to display company visitors and such on regular TVs. Now we have been powering the PI thru the USB Power of the TV - and every time we shut of the TV or Raspberry hard shut down and corrupted the SD Card.

Since we couldnt finde any affordable solution we decided to make a raspberry pi usv which is easly addable to a raspberry pi and is absolutley affordable. After we installed a bunch of these boards on client sites we have been asked repeatedly wether we could offer the solution to a larger crowd - so we did.

you can watch the video on http://www.piups.net we do ship to the UK and the US.

Our software and hardware team will monitor this forum constantly and we are happy to answer to your comments right here in this post.

i hope you enjoy our solution.

cheers,
jonas

Hi.
Might be a good idea to do an English-language version of that page so we all know what you're talking about.

Oh my! Thanks for your comment.

There was a bug, when the page was called with the 'www' subdomain, the german version popped up.

I applogoize sencerly. The page is now available in english!

Looks nice. Wanted to buy one. But, only Bank Transfer? No other payment methods?

Hey 65coupe,

Thanks for your reply!
We are integrating Visa / MasterCard as we speak. That method of payment will be available later today!

Also I Just had an inquiry with a few questions, i figured this might be intresting for all of you.

Will the Pi UPS allow the Pi to continue to operate until the batteries are down or will it always initiate a shutdown once the main power is removed?
-> Absolutley, this is configurable thru the software shipped with the product. the PI can stay up until the batterys are low and will then be shut down correctly. you can also configure it to shut down right away (makes sense for in car applications)

Is the shutdown process configurable meaning can it wait to shutdown until a certain amount of time has passed or only when the voltage reaches a certain level?
-> As mentioned above. Thats also configurable via an easy to use software interface shipped with the pi. (also via commandline for more advanced users)

Also will there be a USA distributor?
-> Yes, we are in final nagotiations with two distributors. you will therefore have a direct contact person in the US.

Hi your project is really interesting, I'd have a couple of questions:

1. is the PI UPS software open source or do you plan to release it under an open source license?
2. do I need to have soldering skills or I can just connect the wires with a simple plug to the GPIO interface?
3. is it possible to use rechargeable batteries and if the answer is yes will they charge during normal operation?
4. if batteries do not charge, how can I know when it's time to replace them?

Thanks in advance!

HI Joe,

Please excuse the late reply we have been extremly under water -

but if you believe it or not - we are ready to ship the second shipment starting wednesday next week.

here the answers to your questions:


1. is the PI UPS software open source or do you plan to release it under an open source license?
-> Yes its open source
2. do I need to have soldering skills or I can just connect the wires with a simple plug to the GPIO interface?
-> nope its plug & play please check out the new video
3. is it possible to use rechargeable batteries and if the answer is yes will they charge during normal operation?
-> yes, we will be providing a optional adapter which lets u even connect a power bank
4. if batteries do not charge, how can I know when it's time to replace them?
-> when using regular batteries it depends very much on your usage if you just use it to shutdown your raspberry pi safely when the power source is gone, you should have multiple months if not years of operation.

I was searching for something allowing me to plug/unplug the power cord of my raspberrypi without having to manually shutdown the system.

I thought about something that would command a relay when the raspberrypi is shutting down, but this UPS is very interesting : I just have to unplug the power supply, and it will automatically shutdown.

However, I would like some precisions :

1. As asked before, how will I know when it's time to replace the batteries? Ok, if I use them only to shutdown the system, they will last long but... I will have to replace them anyway.
2. Will the batteries be charged when the power supply is connected?
3. Do you accept Paypal as a payement method?

Thanks for your answers.

If the PiUSV monitor is open source, where can I find the source code of it? I have bought the PiUSV and downloaded the software, but have not found the source code.

Hi,

And what does the Pi UPS do when the power goes back on when the Pi is in the process of shutting down ? Does it wait for the Pi to shutdown and the reboots it or do one need to reboot the Pi manually in that case to get it back to the OS ?
Best regards
Szafran

I use a USB mobile charger rather then the 6 batts for the Pi UPS:

Why does my PC throw a red flag at your link as suspicious?

This came across my inbox today: http://www.ebay.com/itm/371084804707?var=640249857744

VERY affordable ($6 at time of posting) IF it powers the pi and automatically switches to the battery as soon as it is unplugged. It has 1000mA output, and a 1350mAh cell capacity and an 800mAh pack capacity, which means it should power the pi long enough to manually shut it down. Heck, one could even crack it open and put a bigger battery in there, and some voltage detection circuitry to send info to the pi to shut down when it senses a voltage drop.

I just ordered 15 of them for my digital signage pi's, so I will have an extra one or two to play around with in my free time. I will report back when I test them to see if they work properly to keep powering the pi when it loses mains power.

So they seemingly work, but I've had issues with 2 of them so far. This may be why they are so cheap.

They were able to boot the pi, but sometimes it caused the NIC to fail. The connection lights were lit on both the pi and the router, so I am unsure of what caused this. I have tested a 30 second power off, and it kept the pi on just fine. When I resumed power, it was as if the power never went away. Neato!

So for the 2 that I had issues with, it would boot everything just fine, but eth0 would not be active on my network. When I replaced it with another one, it booted just fine, network worked and everything. My guess is that it is not providing enough amperage to power the NIC fully. Other possibility is that it is not providing a full 5V, and if it is, it could be a very unstable signal.

I have not had a chance to tear one apart yet, but I will soon. They are on sale again for $6, this time at rakuten: http://www.rakuten.com/prod/enercell-13 ... 39936.html

I will report back when I have more progress on the following:

  • Output voltage of both working and defective units
  • Output amperage of both working and defective units
  • Tear down: battery specs, internal electronics, etc
  • How long it keeps the pi after power loss
  • Any side effects from loss of power
  • Any side effects from fully draining battery after loss of power

If you can think of anything additional that I should test, please let me know and I will try my best.
