Cheap 40W Laser Engraver from China

I have wanted a laser engraver for quite some time but the price has always been prohibitive for me. Recently though, I found some engravers from china on Amazon for about $500.00 USD and free shipping. Plus, I contacted the vendor and found that the unit would ship from California. I read all the reviews and they all agreed that the machine is great. However, the downside of these machines was the software that is included. After carefully considering all the relevant information I decided to purchase one.

Conquer the Divide - Faster Integer Division

Conquer the Divide - Faster Integer Division

Introduction

How to implement C-style integer division on a microcontroller that doesn't provide appropriate instructions? In school we learn how to divide long nunmbers [1]. Wikipedia tells us that we can do better in certain cases [2]. However, these algorithm are only better for numbers longer than a certain limit. For C operations they don't give any advantage. This article presents an algorithm based on piecewise polynomial approximation to implement this operation.

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:
