I think you guys will appreciate this scene from Iron Man 1. 

SmartRap, build has moved forward

Between job stuff and family priorites, my SmartRap doesn't build by itself.

But little step by little step, I have nice progress :)

The build itself is ready, I started to plug and test things.

This evening, I flashed the Marlin firmware and tested the head servo.

Enough for a tired man todey, hope to continue to plug the rest of the cables soon.

Why I Hate Arduino

The title of this blog entry is going to make a lot more enemies for me. Not that I need any help there. But perhaps the content will take some of the edge off of it. I really don't hate Arduino, but there are a lot of things about it that bother or concern me, and some that just downright irritate me. And, to be honest, many of the things that bother me about Arduino is how people (try to) use it beyond it's reasonable capabilities. But the Arduino does little to alleviate that, and that again annoys me.

R1D1

This is my first robot project.

I am an electronics and computer systems engineer with over 20 years experience.

The Mailman

 

Long time no see...

I just wanted to share with you something I worked on during the month of January. I particpated in a robot competition here at M.I.T called MASLAB. My robot and team ended up taking 1st place. The details can be found on my website.

I'm sorry that I don't have the time to write a proper robot post about it on LMR.

Learning Electronics Via The J5 Obstacle Avoidance Robot

Hello to the LMR community. This first blog post is basically just an introduction for me and what I am about.

 

Creating a Picaxe 08M LCD Driver ( 2 wire Driver )

A few weeks back I decided to make another attempt at driving an LCD using picaxe. My first attempt was almost a year ago, however when the $6 LCD failed to display anything I wrote it off as defective.

But after a long night where i found it hard to sleep i stumbled on a  site that should me clearly how to power up and set the contras with backlight on. 15 minutes in and i was hooked. LCD light boxes displayed as i adjusted the contrast using a 1oK pot.

3D Printed Linear actuator

Here is a custom 3D printed Linear actuator for activating a lever or push/pulling something or other.

It uses a Cost effective Stepper motor (we all know which one).

From a previous static test i knew that the motor in this worm screw configuration could push close to 2Kgs of force (as measured against my kitchen scales)

The bugbear was thinking of a way to attach a feedback potentiometer to the worm screw...

....I tried linear potentiometers however they were limited in length...

Pixy Out of Box

Well, it finally came in, the Pixy CMUcam5.

I'm still working with it, but wanted to make a real quick note about a few things.

SmartRap received

Here we are: I received all the parts to build my own SmartRap

For the moment, just a quick unboxing:

LMR in Google

I am replying to the message Frits posted on the start page.

I did a qick check about the google presence and there is no sign of disappearance. I am sure it just had a small hickup due the website changing (owner) and/or registration.

As we all want LMR to be the #1 I am also putting links whereever I see fit. Please do the same but do not spam other forums, just place the link where you think it's appropriate.

 

Dagu Robotic Arm 6DoF - Bacuri02 Project

I recently received my Dagu Robotic Arm 6 DOF with Arexx control board 32 servos.

My original project is to use an Arduino Mega to control the arm and then make a wifi connection joystick control.

As I have not received my Arduino Mega board, I started tinkering in Arexx control board that I received along with the robotic arm. Along with the kit also came with a CD ROM which I believed the program to be installed on the computer to control the arm.

Graphene Rocks

I have been searching for some conductive ink for some projects for some time now, its not so easy to get and very expensive.

I have been following :- Robert Murray Smith he is a prolific designer .... of all sorts....

Luckily for me he is currently working on a series of Graphene based products - one of which is conductive ink (just what G needs)

 

Thanks!

Two days back I got a parcel. It was from Thailand,and to my surprise it contained 5 pcs of TQFP32 to DIP breakout boards. First of all I was confused as Ladvien resides in US and he told me that he might send something.

Thanks a lot ladvien,will post pics soon. This is my first SMD soldering. Have soldered three MCUs on them. I shall be glad if I can be of any help to you. Thanks again.
