Rpi O w mobilized: 15ah battery and 250ma solar panel

Its aliiiiiive!

Thats a raspberry pi zero - W epoxied to a 15 amp hour battery (allpowers brand), on the back you cant see is a 250mill-amp solar panel. The pi takes about 100 mill-amps.  So ill get 100± hrs before depletion and the solar panel can run the pi and charge the battery simultaneously, assuming direct sun.

I was going to build one onto the back of my tablet case but it was too heavy.

I connect from any android device via wifi or bluetooth (using vnc over ssh with bVNC app). But i wont drop it cause its not glued to a phone.

Power button + usb port.

Battery can be charged at wall and also has an open 2.4 amp usb power socket.

Cost
25$ battery
25$ rpi 0 W
10$ cables

Never have to plug in again: priceless.

Pi zero w built onto samsung s5 vnc via ssh to use.

Samsung s5 with hyperion extra size battery with built in pi zero w.

Turn on hotspot on the s5

Connect to the hotspot.

Using internal ip address,

Vnc over ssh to the pi.

With the pi youll want xvbf and x11vnc. They help autoconfigure your pi when theres an incoming vnc request. For correct names refer to the options under bVNC at the bottom under advanced vnc options.

I use the bVNC app for vnc/ssh together, but JuiceSSH is also helpful.
Configure the services on their own (ssh - keys in proper folder locations on the rpi) (get your vnc working without ssh). Then use them together.  Make sure to set passwords for ssh and vnc on your pi.

Only alteration to phone was my power  wires wired into the spot where the battery terminals meets the phone.

On s5, from left to right, the first pin is power and the third pin is ground.

Ive also wired in a switch you can see in the photos.

Two final options: a 4-port usb hub or 1-port usb. I opted for the 1 port because there may not be enough lightning juice in the shock-keepers to power too many usb devices. So far had it (both devices) running 5 hrs and im at 45% battery (mobile data off).

Im happy to answer questions.

Leave a comment in that case.

Update: used daily 8 hrs for a week, works fine no issues.

Update : dropbox fix: im using BitTorrent Sync to sync a folder from  the pi to the android, then the phone runs Dropsync app periodically. Result : cloud-synced data on the pi with little interferance from me with a lot of control.

That means my projects and scripts are cloud-saved! Love it. Ive got btsync just doing one folder which has all my linux stuff and scripts,every 30 mins.

Review: raspberry pi 3 b by new non-linux user after 4 days tweaking and learning

Amazon didnt like my review and they can go bleep thembleeps. Heres my full review after 4 days of successes and mistakes.

Never did linux. Bought 1. In love. Bought 3 more from loverpi. This is not a desktop computer. You can do things but this is a development platform and you can expect to be editing config files and learning linux console commands. I would say i am 'skilled' in computers, dos, can program a bit of lua and javasvript.

I have adhd and refused to read documentation until im in the middle. Dont do that. Read as much as you can and try and figure out afew good apps. Wicd wireless gui util saved me after 4 days of berryboot vs raspbian fighting over my internet connection. Again if i had read docs i wouldnt have wasted that time. In about 30 seconds i had berryboot with raspbian running with wifi and ethernet and it has gui controls.

But holy cow i could configure this thing with my eyes closed for Internet. I know how it works well, now!

Tip: do not repeatedly unplug your cord from the pi, this wears out micro usb port on it which is delicate

Use blueman to configure your bluetooth.

Ok - hey, youre up and running, got your wifi and ethernet and maybe vnc set up. Now stop and backup your operating system. If you snafu your customized os with an advanced operation, youll have a backup with your work intact. Good news is, firmware is on the sd card and not in the chips or whatever.

Youll want to read a starter guide. Be careful to add '2017' to your google search questions because people have been trying to configure these things since like 2010 and youll hit old articles you dont want ti follow. Youll find a lot of forum kiddos advising each other. When you can, go to official sources for help (rasbpian, berryboot, linux) websites. Also youll find the occasional high quality tutorial for college level students.

And lots of very good other tutorials, easy to find. Lots of possibilities! So i bought 3 more.. So far.

Anyway, some more tips

A) when you glue on your heat sinks, peel the tape and then remove the glue with acetone. Use a real heat-exchanging paste for real cpus, youll thank me. Some people said their RPIs ran 10 degrees celsuis cooler without the heat sink at all. Remember if you live in the north, the heat sink works better (maine: summer day 60-80 degrees, nights 50-65 degrees).

I suspect in warm climates they dont do as good a job. Even 5 - 10 degrees F of room temperature can improve function of any computer.

The programming languages have a built in interface that will run several kinds of code. Since i know lua im looking forward to all kinds of coding projects. You can really customize your os with code.

Do not think you are getting a 'cool customizable os'. It is that. But its really not going to be as pretty to look at or have the fancy menus of windows.

What it is is simple menus - powerful menus. At first glance youre like 'oh its just a shitty computer'. But after afew minutes of poking around i knew i preferred linux over windows. Its simple, but its also complex and powerful.

So,you can buy this. You can set up wifi super easy if your not using berryboot but instead using Raspbian by itself. You can download abiword and write documents, you can write and test code super easily. You can browse the web, get email. Only 1 gig of memory so, try not to have more than 3-4 windows open if theyre browsers.

But heck thats a lot of functionality for a 40$ computer the size of a deck of cards.

I love it. Im setting up media centers for my family soon. (google: kodi) and also a retro gaming system (retropie).

With berryboot you can install several OS without having to d/l files and write disk images.

Got a 12 yr old kid who loves computers? Get her this. She will impress you.

Are you skilled with computers but not sure what to think of rpi? Get it. Get 2.

Do you just need a barebones pc for reading the news or writing drafts? Get it.

Some things you have to improve yourself:

Case comes with gaps for machinery,but is tight around usb fixtures (its a good case.) I epoxied metal screens over these gaps to protect from animal hair (i have cats). See photos.

Audio output from the headphone jack is staticy. There are probably some things you can do to get proper sound. I bought a usb sound card for 7$ that will supposedly work better from what ive googled. Im dont know anything about circuits - actually was hoping to learn and it looks like i will get the opportunity.

Thank you liveRPI, about to make 3rd purchase. Watch out - i ordered 10 lbs of coffee and the amaxon packers threw my pis and sd cards loose under 10 lbs of instant coffee containers. My first purchase from loverpi was fine because i did not order food. Fair warning.

But luckily the pis are well packaged, inside a boxboard box and inside a waxpaper-like bag. At first I was like, a bag? I love it. Anyway everything survived, thank you loverpi.

Just don't click "group my shipments together" i guess when buying electronics. Have not tested the crushed sd and usb cards.

Ive replaced the scotch tape with epoxied screen.

Incidentally if you want heat sinks, get the aluminum ones that flare outwards. I was comparing temperature reduction reports and the flared out (looks like hedgehog, only 1 on amazon) and the flared ones perform 20 degrees celsuis more cooling than the ones sold by loverpi on amazon. 

Buy it. Have fun! Then buy 5 more.

The origin of water

When the sky becomes a fountain,
I am a droplet I believe,
falling sky onto a mountain
I rest upon a tree’s green leaves.

I am a mote of nature’s wrath,
long before I reach the stream,
seeking but a single path,
I own myself a single dream,

I fall unto the forest floor
and ever journey down and down,
towards the ocean evermore
leaving the mountain’s rocky crown

Now I am a forest brook
coursing always down the slope,
changing from the form I took,
to be the drop again, I hope

But now I am a river, raging
and becoming ever larger,
a downhill warpath I am waging
as the rain falls ever harder.

I travel far throughout the wood,
growing always ever wider,
I am the flowing river god,
I am the splashing mountain rider.

I etch the hills with winding scrawl
eating ‘way at rock and bone,
I am now a waterfall,
falling, flying, stretching down.

And when I, the river, reach the sea,
we combine and I am gone,
full of salt but finally free,
forgetting I was a drop of rain.

But when the waves stir up my soul,
I leap and rise above it all,
in my travels I see the whole,
I become again the droplet small.

Now I am the ocean spray,
rising on the breeze to height,
evaporating on the way,
I am mist in sailor’s sight.

Up and over the dark blue bay,
as a fog I rise above,
reaching for the Milky Way,
completing the cycle that I love.

I travel far from ocean chop,
and when the clouds begin to pour,
I am again a tiny drop,

fated to be the river once more.
