DAGU CNC mill controller - first prototype

I've been developing a CNC controller for DAGU. The project originally started late 2012 but got shelved because of other projects. Now we've dusted it off and plan to finish it in the next 6 months. Unfortunately blog post don't support video so watch the video that explains the basics by clicking on the link.

Controlling powerful motors

Hello guys,

 

I want to control a powerful motor not like the ones used (servo motor) I need something of the ones which work on 110\220

 

I am not sure if it is possible using picaxe, if so is there any tutorial or has anyone done this before?

 

Obvioiusly it should be powered externally and controlled by picaxe

 

If this is not possible what can the strongest servomotor provide me? Can it for example to move the steering wheel of a car?

Attiny 2313/4313 servo driver

Hello everyone!

Attiny85/45s are great for small projects because nearly all pins can be used to drive servos simultaneously.

However 5 servos are nice but not enough. I found out that I have bought some Attiny4313s a while ago. They 20-pin chips that can be programmed via arduino. Now I am wondering how many servos it can control. There already are different approaches:

T'REX controller now available from Sparkfun

Good news for anyone wanting to control big motors up to 24V with stall currents as high as 40A. The T'REX robot controller is now available from Sparkfun.

https://www.sparkfun.com/products/12075

The controller is basically an Arduino Nano 328 with a switchmode power supply and high current motor drivers with electronic braking and current monitoring.

T'REX robot controller

 

The T'REX robot controller makes controlling robots easy!

The Arduino compatible controller comes pre-programmed with sample code that lets you control it with a supplied Android app, Radio Control or with an external controller via I²C.

theory vs. soldering

Well...my robot is far from being able to be presented.

In fact I try to build/solder some parts on my own, which seems to be more challenging than expected. Actually I´m soldering a h bridge with its controller based on oddbots h bridge - without the current sensing part - and I just hat to face, that it doesnt work. I guess its not due to oddbots design, but to my soldering skills and or adapting to a simple board design, since I solder though-hole.

I hope I can figure out the problem soon...

Beginnings

 

May 19, 2013

I am building a robot controller board using a Zilog Z-80 processor.  For those who don't know, the Z-80 was one of two major CPU chips in the late 70s and early 80s, before the IBM PC ruined ruled the world. The other was the 6502.  I hope you will follow along as the project progresses.  It will be fun.  Why on earth would I want to do such a thing?  Glad you asked.

It's a remote control for a Stewart Platform. Soon it will be a 6DOF HID joystick

A hexapod for my son to ride on - a big experiment

After seeing the weblink by bdk6 "inspiration for Hexapod builders" I was inspired. The video is of the "Mantis" turbo diesel all terrain hexapod.

Ok, I cannot afford to build a 2 tonne turbo diesel hexapod but I can build one big enough for my 8 year old son Shi Sen to ride on. My plan is to have almost the entire robot laser cut from 6mm plywood.

Spider controller

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.

New Micro Magician V2

The new improved Micro Magician V2 is here! It has all the features you loved in the original Micro Magician but with an ATmega328P and improved power supply. The new black and yellow PCB looks great and is easier to read.

You can now download the manual from here: https://docs.google.com/open?id=0B__O096vyVYqUjNXVV9RMmFuNkk

Prototype animatronic head

Well my boss is involved in organizing a robot head building contest in China and asked me to make an example to inspire the contestants. I know many will just be made from cardboard and wood but I decided that if I was going to spend time on this project then I wanted to make the most of it and develop a new product.

wild thumper + wild thumper motor controller how do i let it start driving?

hello,

im new t building robots and i got a question.

i have brougth the wild humper 6 wheeled chasis and a wild thumper motor controller.

 

everything is ooked up propperly, 

now my question is ow that i uploaded the standard program from my laptop on the controller(only changed to serial instead of rc as i want to drive it via my laptop). what code do i need to change to let the servos start driving?

myself i thougt this peace of code :

 

 

Jameco now sell the Micro Magician robot controller

Good news everyone, the Micro Magician is now being stocked by Jameco as well as Rocket Brand Studios.

Fancontroller

Right, back again with an update on my idea for a kick-ass fanctroller. So far, I've been coding away and right now, I'm up to the point where the actual fan control is implemented (I've already written the LCD-commands, several input functions, a setup and a menu.) But I'm having some problems.

Micro Magician robot controller - I can finally tick the project complete box!

I started designing this controller in December 2011. After 4 months and 2 previous revisions it will finally be shipping out April 2012. I think this is DAGU's best Arduino compatible robot controller yet!

Designed for small robots using small batteries, the Micro Magician is a 3.3V controller running at 8MHz.
Working from 4.5V to 9V means this constroller can run from a single LiPo cell or 3x NiMh batteries.
Reverse polarity protection means no blue smoke if you get your power wires crossed (reverse polarity diode rated at 3A).

My first PCB

Hi guys,

I started on some unfinished projects again but I could use some advice. I'm trying to build a board for the mini reef that can switch 6 devices (solenoid valves) at 12v DC with the PIC/Prop controller. I'm using diptrace for this as this seems to be the favorite choice. So far I love it.

I came up with the below but I'm running into some problems with the traces. Maybe someone can point out the right direction as I think that it must be possible to cross over a line (with some electonic component maybe)? The red circles are the problem areas.

Dagu Rover 5 & Arduino Uno /Help

Hello everyone.

I'm trying to make a robot for experimentation, something i can use in my studies aswell. I'm studying Electronics & Computer engeneering, first year, and i want a platform that i can improve in the years to come. 

I started playing around with LEDs and an arduino some time ago, this week i bought a Dagu Rover 5 with 4 motors and 4 encoders. The problem is i don't have the 4 channel DC motor controller. 

The mother of all fancontrollers... Hopefully

So, I'm the process of making the -in my opinion- ultimate PC fan/pump controller for use with a water cooling system.

The idea is to make a bracket which fits into a 5.25" bay and holds an LCD, some type of input (probably joystick) and an arduino, so the temperature responses are completely programmable. It should have three fan/pump channels and 3-6 (however many ADCs I have left, at least 3) temperature sensors.

How do you use a L293D Motor Controller with an Arduino MEGA?

I have recently received my order from ebay. A L293D Motor Controller for my first robot. I read the datasheet and other guides but i can't figure out how to use it, please help! I didnt order 2 so i only have 1, if it fries, i cant get another one or i have to make one. :(
