I try a project using motion sensor.
if motion detected, turn on a LED.

Program write in Python.

#!/usr/local/bin/python
# -*- coding: utf-8 -*-
import time
import onionGpio
from datetime import datetime

# LED GPIO
led_pin = 0
pir_pin = 9
sleeptime = 100000
led_light_up_time = 1

led = onionGpio.OnionGpio(led_pin)
pir = onionGpio.OnionGpio(pir_pin)

led.setOutputDirection(0)
pir.setInputDirection()

while True:
    value = pir.getValue().rstrip()

    if(value == "1"):
        print datetime.now(),
        print "motion_detected"
        led.setValue(1)
        time.sleep(led_light_up_time)
        led.setValue(0)

It seem work well.
but a problem is when press Ctrl-C to stop running,
then try run again, some time cause ”Resource busy“ error.

root@Omega-6F83:~# python motion2.py
Traceback (most recent call last):
  File "motion2.py", line 17, in <module>
    pir.setInputDirection()
  File "/usr/lib/python2.7/onionGpio.py", line 158, in setInputDirection
    ret         = self._setDirection(_GPIO_INPUT_DIRECTION)
  File "/usr/lib/python2.7/onionGpio.py", line 134, in _setDirection
    status      = self._initGpio()
  File "/usr/lib/python2.7/onionGpio.py", line 46, in _initGpio
    fd.close()
IOError: [Errno 16] Resource busy
root@Omega-6F83:~#

May be onionGpio not release some "Resource" after Ctrl-C.
How can I fix it?

Sorry for replay late, I try to debrick , because I am quite busy and try many time but still not work.
it seem hardware not stable. see following describe. any thing wrong?
(btw, I backed 2 Omega2, hope go smoothly!)

1. Usually only show following message then freeze.

I am give up!

@Gabriel-Ongpauco Thank you so mach. I just got the Expansion Dock. I will try to debrick the Omega ASAP.

@Gabriel-Ongpauco I still not get the Expansion Dock, is it still on the way?
or any other new way to debrick the Omega?

@Gabriel-Ongpauco Thank you so mach.

@Boken-Lin Sorry, about how long to get "ethernet expansion"?

@Boken-Lin My address still the same. Thank you so mach.

@Boken-Lin Thank for replay.
I was initially use a phone charger, I check the current only 30-100 mA.
but 2nd day I can't browse and ssh into Onion and can't find it on LAN with tool "fing".
so I trying serial connect to see what happen.
the TTL output reboot was on the case using serial connect, it connected Notebook PC USB and OMEGA micro USB.
Today I try use powered USB hub (HUB with 2.5A power supply ), unfortunate I still can't start httpd.
I think if only current 30-100 mA, Notebook PC USB power is enough.

Thanks! & Merry Christmas!

@Boken-Lin because I can't start httpd. so I try to find problem.
what is "serverip=192.168.1.100" meaning? the Omega ip?
I set PC ip to 192.168.1.111 and ping 192.168.1.1, .100, both no reach.
than I try ping from Omega self, and found it "not alive".

how can I make Omega work. is it any way to use USB serial to make a solution?

I try it, still can't start httpd.
Also it is stranger, why ping self-ipaddr got

Error: ping failed, host 192.168.1.1 is not alive!

I try building my own Ethernet expansion, it look good, PC LAN port LED start blinking.
but httpd command not work, I try reconnect the Ethernet cable and try again. It still same.
any way I can make sure the connect ?

Thank you so mach.
I just order breadboard and jumper... kit, I will let you know once debrick the Omega.

Yes, I follow the links tried to Using-USB-Storage-as-Rootfs but can't mount and not continue,
because I try to plug USB storage in but nothing happen. not found any under /dev/sd*
https://wiki.onion.io/Tutorials/Using-USB-Storage-as-Rootfs
https://community.onion.io/topic/159/install-lamp-ftp-and-phpmyadmin-on-your-onion-omega

I don't have an ethernet expansion, neither 2nd Omega.
I do have Raspberry Pi B, if it help building my own ethernet expansion...

Nothing, Actually I try many combination. Not any work now.

1. Omega + Dock + Relay Module (only 1st day work)
2. Omega + Dock + Relay Module + 8G USB storage (Ext4)
3. Omega + Dock
4. Omega + Mini Dock

Yesterday I turn on Onion with dock, connect to net and make update. anythinglook OK,
Just I try to plug USB storage in but nothing happen. not found any under /dev/sd*
Today I try again, but I can't browse and ssh into Onion
Last I try serial connect, just saw boot loop message forever. even I hit Enter,...
