Netgear is wireless adapter. Ordered a 22000 batterie pack, hopfully is pass-through. Tried Rpi2, power consumption is same as Odroid.

i was just thinking lately how to make more money, and i think the solar energy is very cost efficient

we can setup something like an altcoin miner, and then pay the profits in nxt or ardor, that can boost nxt's price doesnt it?

Hi Zuqka,

nice to see this clever setup of a nxt forging rig!

i have some questions about the new setup (24w + 22ah powerbank)

how long is the rig independ from the power grid ?
do you have to recharge your powerbank ?
how big is your sdcard on the rig ?

keep forging

Hi Pazor,
Am glad you like it and hope we all help and spread the word about Nxt with whatever we can best.
The SD card on Odroid is 16Gb: http://www.hardkernel.com/main/products/prdt_info.php?g_code=G145636129743

The solar + powerbank combo is 24/7 off the grid! It's only struggling to keep up on the first sign of light I guess and I found one morning that powerbank even shut down although it had juice left.
Gonna watch it next days but my goal is to keep it 24/7 off the grid.

hi zuqka,

i think it is quite diffucult to keep the rig 24/7 off the grid. you need bright light days to charge the powerbank.
but i am very interessting in your results.

let us known the development of the solar powered nxt forging machine

I have come with a solution that keeps it running for the 7th day off grid. Got an additional powerbank, EC Technology 22400 mAh:
https://www.amazon.de/gp/product/B00F5Q4F0U/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

and this one doesn't allow charging/discharging simultaneously which is a good thing in my case (charging on solar/discharging at night). The EC Tech powerbank is charged constantly during the day from the solar panel and after the sun is out it charges the Ravpower powerbank which delivers constant electricity to Odroid. We had lately quite a few sunny days and I will monitor it on cloudy days.

so you have now 22ah + 22ah power capacity on both powerbanks.

your solarpanel delivers 5v @ 2.4a on each usb connector = 12 W
on 6h sun = 72wh

i suppose your forging device need around 85wh per day = 17,3ah running 24h a day

so if you have 2 or 3 days cloudy days ... your powerbanks running out of power.

am i to pessimistic ?

a good blog post is:
http://www.voltaicsystems.com/blog/powering-a-raspberry-pi-from-solar-power/

of course, i am very curious about your experiences

We were blessed with almost constant sunny days last weeks. One and a half cloudy day didn't bring it down. The Rpi2 consumes less power than odroid, that's for sure. Keeping it up in late autumn and winter it's probably pretty utopian.

please continue post your development !

can you check via a usb multimeter the consumption of the odroid c2 while its forging ?

Am afraid I don't have such a device to measure the power consumption while forging but I found some data on internet so we get the idea:
• Idle: 0.33 ~ 0.35A
• Heavy Load CPU/GPU (Antutu benchmark): 0.84 ~ 0.88A
• Kodi main menu on Full-HD(1080p) TV: 0.33 ~ 0.37A
• Kodi FHD 1080p movie Ethermet SMB play(1080p TV): 0.45 ~ 0.50A
• Kodi UHD 2160p movie Ethermet SMB play(1080p TV): 0.55 ~ 0.65A
• Kodi UHD 2160p movie Ethermet SMB play on real 4K(2160p) TV: 0.60 ~ 0.75A
• iperf ethernet: 0.47 ~ 0.48A
• iperf 2.4GHz Wifi: 0.49 ~ 0.50A
• iperf 5Ghz Wifi: 0.67 ~ 0.72A

So we can say the system consumes around 1.8~4.0 Watt for general use cases.
