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.

Help to convert a blank ATmega328 into a speech synthesizer chip for under $5

Introduction:
Some time ago when I was looking at the cost of speakjet and other hardware speech systems I remembers that back in the 80's there was a program call S.A.M. (software automated mouth) that ran on my Atari XL. It was also available for the C64, Apple and possibly some other systems.

Burn the bootloader or write sketches directly to the MCU
The Arduino and Arduino compatible boards all use a small program called a bootloader to take serial data from your computer and store it in the Arduino's memory. … Read more

Topics for Lumi's next photoshoot

Occasionally Lumi does a photo shoot with some very pretty girls and is good enough to share with us. I would like to get suggestions for Lumi's next photo shoot. There is no guarantee he can or will do it but we can still ask.

Max's gifs often make me wish Lumi could do a photoshoot like that. Hopefully Max can post a few here for inspiration. This was my inspiration for this post:

Please post suggestions of what you would like to see as a theme for Lumi's next photo shoot.

This is a forgotten robot post that sat in my [Drafts] folder for a couple of years.     I want to experiment with mapping an apartment and having a robot … Read more

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.

Specifications:

Increase torque or reduce noise in DC brushed motors
By default, most Arduino pwm outputs are set to about 490Hz or 980Hz. These frequencies work quite well with small dc brushed motors but can cause unwanted noise or … Read more

Updated instruction manual for Mini Driver

The Mini Driver was released by DAGU some time ago. It is essentially our Magician controller in SMD format. Unfortunately the engineer who designed it does not have very good English so I was asked to re-write the manual. You can view/download the manual from here: https://drive.google.com/file/d/0B__O096vyVYqczRjX1k5LTRkcjA/edit?usp=sharing
