My Repscrap: DC motors and rotary encoders for Z-Axis too?

 

 I took a few pictures this morning, to give me something to think about while I was at the cottage for the weekend.

Why I Respect my Robot Elders

I've been forced to take holiday from work, Bek has closed my lab until June 1st, and I don't do down-time well.  Given I'm without a lab for the moment, I'm forced to seek other outlets for my brain.  So, I thought I'd write a few reflections regarding my experiences at LMR in the last two years I've been a member.

I thought I'd write about something I've noticed about LMR in regards to the influx of knowledge: Respect for our Robot Elders.

What's a Robot Elder?

newbie

Hello guys and girls,I am a new user and would like to gladly greet you all.I am terrible with robots but will improve with the LMR community.This blog entry contains a few ideas I will soon use to create some robots . Idea number one is that my first robot will be a line runner.I have not come up with a design but I know it will be very simple.The whole point of creating the robot is to improve my skills with robotics. My second idea is a navigator robot which will lead to the destination that is pinpointed.

beware of sainsmart!

some of you know about my experience with sainsmart some of you do not. and some have had their own.

this is a warning to all new people that may be interested in buying from them . DO SO AT YOUR OWN RISK

Just when you thought your robot costs are out of control...

Saw this on the Robotics Tomorrow website. When you watch the video, at first you might think he's a cute little guy, but actually, he is rather large, and EXPENSIVE! Starts at $50,000  
Makes the cost of what we make seem so affordable. Next time your significant other complains of your robot expenses, show them this bot... (he is rather cute though...)

I am a giant!

     Because as you know your height is the same as the distance from  fingertip to fingertip.   And the distance between my fingertips is over nine miles.

     And that means you have to be careful when using butcher knives.

     But don't panic, it was only about mm lost.  But that’s not to say i wasn't attached to that particular mm.

     So before using any kind of cutting tool think of the worst case scenario and don't have your fingers there.

A Military Science Exhibition/Competition - MSTC

Hello there guys. Long time no see. I was wrapped in a US college application season this year so got a bit busy with things.

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.

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.

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.

Long Live LMR   .....................ALABTU !!!!!!!!!!!!

I hope it's a phase

Lately I can barely bring myself to look at the lab.

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.

Now that was FAAAST!

Hey there guys,

A week earlier, our fantastic LMR member Lumi was kind enough to sponsor me a gripper arm and a pan tilt bracket (for 3DOF). I was planning to use it in a project for a local exhibition. More on that soon! Let's see how the shipping went.

Kossel Build

03/11/14

I'll fix pics when I get home.  Was trying image hosting to relieve Juliette.  Didn't work.

Well, post came.

I finall have "all" the pieces for my 3D printer.  I sourced a few of the major parts and ended up buying the rest from www.builda3dprinter.eu.  And today that order came in.  So, let me review.
