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.

Wild thumper slow comunication through ethernet TCP

Dear Sirs.

First of all thanks for your time, help and sorry for my English.

I'm am working in a Final Degree project with Wild Thumper 6WD chassis, T'Rex Controller and Arduino MEGA 2560 + Ethernet Shield + Gamepad (connected to the PC)

The communication between T'rex Controller and Arduino Mega is made through I2C BUS (using the T-Rex tester example code from DAGU). Then I created an application using Windows Presentation Foundation which connects the Arduino Shield (using TCP socket) and a gamepad connected to the PC by USB (using AForge library).

A Robot Making a Difference

This is a true story...

My family consists of me, my wife, 2 cats, and 1 robot...Anna.  Lately we seem to learn more and more things from Anna.   Even though Anna is off most of the time, I am often learning and passing on new and useful or interesting things to my wife that I learn from Anna.

Capacitors for smoothing servo current surges

I've built what I thought was a nice clean approach to the oft-recommended practice of parking a 470uf cap on the power lines to my servos. I have 6V coming from my voltage regulator to the postive/negative bus strips on a small PCB. I've pulled a positive and negative wire off of the bus for each servo (3 servos total) and put a capacitor across each pair of wires. One servo should then connect to each pair of wires.

Idea for Treaded Robot

I've been meaning to show Dickel my experiments with Vex treads. His MDi #2 continues to look amazing but Dickel has expressed some concern about the frame of his treads. Rather than using increased thickness of polystyrene, I wonder if some sort of box shape could be used to increase the stiffness of the structure.

Here are some photos of prototype tread mechanism.

Dagu Rover 5 PWM Settings

Hey All,

So I've been building a rover using a (Dagu) Rover 5 Chassis, a Rover 5 Driver Board and an Arduino Uno.

It's wired up fine and I can send instructions back and fourth to the motors no problem but what seems to be an issue is the speeds which the motors are turning at. If I can set the speed at 100 (i.e.

The <20€ European open robot kit(work in progress)

The purpose is to make a bill of material to make an easy to build, easy to hack, cheap and full of features robot.

There are various builds, so it's better to list components that fit the bill (easy to use, cheap and readily available from arduino kits and chinese e-commerces)

IR and ultrasound based positioning beacons

I have this idea for a positioning system based on IR+ultrasound beacons. It is very simple, and I'm surprised that I can't find anything like that already in use. I guess there are some problems that I can't see, so I wanted to ask you to point the flaws in my idea before I invest time and materials into chasing a pipe dream.

The goal is to get an accurate position of a robot inside a room that is decorated with some additional beacons. The positions of the beacons are known to the robot, so that it can position itself relative to them.
