a step closer to robots

well, I'm back.

"back with a 3d printer" kind of back.

took a week off earlier this month for a stay-cation, and during this time of peace, I decided it was the right time to get my hands on one.



behold, the Monoprice Select Mini.
thoughts so far:
- very inexpensive for today's standards (got it for $200)
- produces great prints
- very non-proprietary

this review convinced me in the end that this printer is the one.

by the way, the above picture shows the 3d printer with the "sample filament," which I soon realized was way, way too little to do anything.

I honestly didn't know what I should do with it at first, trying to find 3D models to print in the internet, until I stumbled into this.

an open-source, 3D-printable robot.

it's always been a dream of sorts for me to build a controllable hand.
it was my intention to build something like that during one of my college projects, but it ended up being something else (software) that is controlled (the glove controller remained).

now, this printable robot offered a printable hand (and forearm, and bicep, and shoulder, and head...).

at this point, I've actually already printed a lot of parts and am pretty well-into the process of building this.



I will elaborate my progress so far in the next post.

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 ...
