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.

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.

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 ...
