Botboarduino drivers

Ok guys it's been a while since I've been on I'm glad everything is picking back up.

I recently had to wipe my computer after getting a virus. Which means I lost all my drivers and code and etc. I managed to get arduino up and running but my botboarduino needs drivers to work. I'm kinda freaked out about catching another virus and I can't seem to find the correct drivers for ft232 uart. I tried one place but it keeps asking me for a password to open it. And when I point the device manager it refuses to see the zip file.

My artificial neuron approach

February 12, 2015

A single artificial neuron can represent some simple Boolean functions like OR, AND or NAND and some like XOR not, because a single artificial neuron can only learn linearly separable mappings.

Example. Perceptron for the AND function:

walks on two legs using four servos

What questions to ask during an interview

More and more I find myself interviewing new staff for our company, with the remit being - find another you. I am currently overloaded justnow because i am multidicplinary, but i cannot seem to find anyone else who is - they are either, mechanics, programmers, electronic engineers or mechanical engineers. What kind of questions can i ask to dig up the real interviewee? The boss wont let me base my decision to hire on the ' do you own a raspberry pi? Or have you ever wanted to build a lifesize dalek?
