Hi all,
I had a lot of trouble with motor driver boards and my Wild Thumper 4WD chassis - in the end I bought a more expensive motor controller said to handle 60A. I am controlling the paired (left/right side) motors by PWM signal and it now drives forward/backwards/left/right etc.
Hi all,

I have an Uno controlling a 4 channel Dagu motor controller with encoder support. Got this a month ago. (It's the red PCB version).
Although it works, I have read that I shall not power the motors before powering the control logic.
But does that really mean that if the controller voltage dies out in the field, and there's still juice in the motor batteries, the Dagu controller will burn ?
I saw OddBot said this might be the case, at least if you powered it up in the wrong order.
A small autonomous robot that wonders around. It's built out of parts I recieved for Christmas, such as a Rover 5 platform w/ driver board. It currently doesn't run. The only thing I need is jumper wires, which I'm gonna pick up at Radioshack tomorrow. I'll update when I can get it moving.
This challenge is simple. Build a robot that can play naughts and crosses (Tic Tac Toe) against a person. It does not matter how. points are awarded for originality with bonus points if it can win or be drawn every time.
You can use any processor from a picaxe 08M to an IBM BlueGene/Q super computer. You must post video of the robot playing again a human for 3 games in a row.
The due date is 1st of February, 2013.
There will be 3 prizes:
I will judge the contest.
As mentioned in my blog, "Multipurpose Mini Machine" DAGU wants to develop a low cost CNC machine kit. The models shown here will not be the final product, they are simply what I used for testing the quality of the components.
Part of the kit will be an Arduino compatible controller. Ok, I know, nothing new so far.
The 12 DOF hexapod kit from DAGU is one of the simplest hexapod kits ever!
Quick and easy to assemble, the body only consist of 12 leg segments, 12 foam rubber feet, 12 servos and a base plate with a hole pattern that allows controllers and sensors to be easily mounted.
The DAGU Red back Spider controller is an Arduino Mega (1280) compatible controller that is especially designed for driving a large number of servos. All 70 I/O pins are terminated in servo compatible 3pin male headers as well as the standard female header and the power supply is a switchmode power supply delivering 5V @ 3A from an input voltage of 7V - 32V.
The new improved Micro Magician V2 is here! It has all the features you loved in the original Micro Magician but with an ATmega328P, improved power supply that can work at lower input voltages and both 5V and 3.3V LDO regulators for powering all your sensors. The new black and yellow PCB looks great and is easier to read.
