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.

dabbling with cylon

I'm playing around with Cylon JS whenever I have the time. in order to use the leap motion for control, the hand control will need to communicate with the pc that is connected to the leap motion device (leap motion does not provide an arm/linux driver). it seems that Cylon devices can communicate with each other through socket.io or http, and I am currently playing around with that.

interfacing alcohol sensor with the led

Programmed the Arduino to have the alcohol sensor play with the LED display. I had the display show either "open" or "lock" depending on the alcohol sensor level. Here is the result: Notice that this has a very notable flaw with respect to its potential use as a "breathalyzer lock": it stays "open" as long as there is alcohol present, which only then "lock"s. This means that currently, if you leave it alone (no breathing into it), it will keep the device unlocked. This is something I will have to resolve. code used for this: int del = 5000; int gasPin = 0; int value = 0; int lastValue = 0; void setup(){ // Serial.begin(9600); pinMode(12, OUTPUT); pinMode(11, OUTPUT); pinMode(10, OUTPUT); pinMode(9, OUTPUT); pinMode(8, OUTPUT); pinMode(7, OUTPUT); pinMode(6, OUTPUT); pinMode(5, OUTPUT); pinMode(4, OUTPUT); pinMode(3, OUTPUT); pinMode(2, OUTPUT); pinMode(1, OUTPUT);...

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 ...
