alcohol sensor (and some patience)

Soldered the alcohol sensor into something that is connectable:


I tried to connect this to the Arduino, as I had the appropriate circuitry, but I did not get any legitimate output from it. 5V going in, 5V coming out with no variations. Nothing seems to be awry in wiring, as the circuit seems to be grounded properly (and the 5V current is flowing). 

There are a couple of potential factors as to why I'm not seeing any results:

- I'm using a 10k ohm resistor, while some guides (and the datasheet for the sensor) asks for 100-200k. However, there seems to be a good amount of people using 10k and getting at least some kind of result. A batch of 100k ohm resistors I ordered is on its way, so I guess I can try with them when they come.

- This site claims that these sensors take 24-48 hours for its signals to be stable. It also tells me that I should not be powering the sensor directly from the Arduino, which I have been doing, out of concern that the power draw of the sensor might damage the board. I did receive the voltage regulator required for a secondary power source, but I'll also need a capacitor and a 9V battery connector, which are both on its way.

Let's hope I didn't get a dud and wait for the parts to arrive.

websockets and mobile networks and ssl

Gahhh. Just going to ramble on this one: Websockets is unstable going through cellular networks Searched Google and solution seems to be SSL connections Tried to implement, and it works to some extent,  but realized that I'll have to have both Apache, which was running my web front end, and Tornado both listen to 443 which cannot happen Realize finally that Tornado is a SERVER just like Apache Try to implement web client through Tornado It works but Websocket server and the web client still different instances so still can't have both listen, or that's what I'm thinking but I don't have time to think about it at present. Gotta sleep.

GPIO testing

Since the environment of the client-server-target is currently quite functional in the messaging standpoint, I decided to try connecting a simple LED light to the Raspberry Pi to see if it could "open" a door when the command is received. Installed the RPi.GPIO module (a Python module that gives the user command of the GPIO--General-Purpose Input/Output--ports in the Raspberry Pi) and connected the LED light to a GPIO pin. When the target received a request message, it would signal the GPIO pin to drive a current to the LED to light it up for 2 seconds. in main: if __name__ == "__main__":   GPIO.setmode(GPIO.BCM)   GPIO.setup(17, GPIO.OUT) in the on_message's request-received logic:      GPIO.output(17, True)      time.sleep(2)      GPIO.output(17, False) The video is a weak visual result. You can a click when the LED lights up; that was the sound of the key being pressed that sent the request message. Now, tim...

pwm..

I just realized that the RPi.GPIO library (for programming the Raspberry Pi's input/output) already has PWM control, giving me a much more efficient control of duty cycles... At least the previous exercise ("duty cycle testing") refreshed me on it. PWM control on RPi.GPIO: http://code.google.com/p/raspberry-gpio-python/wiki/PWM
