Beer Can Collection

When I finish my work and return home on a Friday, I'm often in need of relaxation, after all I've worked hard all week. I've found drinking beer to be an excellent form of relaxation, however this activity can meet with numerous pitfalls. For example, it would appear, the bottomless beer can has not yet been devised by our scientists, or inventers. The work around to this problem is usually to store a set amount of beer in individual containers, often made of aluminum, with a convenient opener on it's top side, which doubles as a mouth piece.

Kirchoffs Voltage Law and Current Law - is there easier math for this?

I think I understand the simple examples for this law, thought the math (algebra) is a bit daunting as its been many many years since high school, and I wasn't very good at it then. The more complex examples make me dizzy.  I have to believe there is an easier way to understand and use this law in my robots circuits. Or is this something that I will rarely use? Is there an easy "rule of thumb"?

Here is an example from the class, not even terribly complex, but seems that way for me.

Building strapping

Im not sure what it's called, CTC can you enlighten me? But it's cheap and easy to work with. I've used it on Retro bot for the extra battery holder http://letsmakerobots.com/node/8004 You should be able to get it from you local building supplies store. Easy to bend, and cut it with tin snips.

The Parallella Board?

I was wondering what people think of this board and the supercomputer that this guy built with them.

The Board:

https://www.parallella.org/board/

This guy built his own supercomputer with 8 of them (each with 18 cores) wrapped around a gigabit switch and a couple of Intel I3 NUCs.

Personal assistant robot

Hi all,

I have plans for a robot for a college project: in short, this is a personal assistant robot. It should be able to use Wolfram Alpha (just like Anna) to get information on spoken search terms (I.E. voice recognition) and output them using text-to-speech. This is all for now, as I want to have a working base that I can develop of my own accord.
