MyLaunchPad

 

This is my blog on the TI LaunchPad. A new platform for me to experiment with.

Note: The structure of this blog itself is a bit of an experiment. I will make posts to the forums with 'MyLaunchPad' in the tags, and include links to my posts in this blog. So the blog will be a collection of links to forum posts.

Steampunk Robot

I attended the 2010 Steampunk Worlds Fair in Piscataway, NJ.

This bot took first place at the Mad Science Contest.

Here is a less dramatic, but more in focus picture.

Yard Gnome Blog (was Mobility Scooter!)

 

 

 I am building an outdoor robot named Yard Gnome to help around the house. I'm starting from a mobility scooter, kettcar and other parts.

Update 2011-07-10

 

I was asked to bring Blind Lemon along to appear with me on Make: Live this coming Wednesday. Poor BL had been sitting in a box, and was a bit worse for wear from my kids playing with him.

Update 2011-07-13 (in the wee hours of the morning)

Mr. Suspense

Just starting a build blog for the Mr. Basic Challenge II.  When I get some more progress I will post pics and make a robot page.

I'm still developing ideas, but I liked Gareth's work on a suspension system for the original Mr. Basic Challenge, so I'm starting with that.  My suspension will use steel cable instead of polymorph for a flexible power transfer system.  Ultimately,I want to try a four wheel independent suspension, but I will start with the front axis being on one suspension platform and the rear on another.

Nobody's perfect, least of all me.  Here I intend to record some of my roboting mistakes for my own good.  Perhaps you can learn from my errors, or even contribute your own.

Steam Punk Robots

I was visiting my sister this past weekend. I showed her son Alec some of the great bots here on LMR. Alec has a couple of interesting model engines, and has been trying to generate electricity with them. His dad actually does this on a bigger scale with diesel engine running biodiesel and a generator.

Anyway, one of Alec's engine models is a Stirling engine. He has this model.

Mr Boston

This is a concept for a drink server robot, Mr Boston. My initial concept is to build him out of an ice cooler, adding wheels, sensors, actuators, etc.

Some initial thoughts:

Yin and Yang

This is an idea for a pair of matched robots, "Yin" and "Yang".  This pair will be almost identical in phyical construction, but very different in programming.

Yang will be aggressive, and constantly seek to attack Yin.  Yin will be passive, but not defenseless, preferring to dodge and avoid rather than directly confront.

Slip Ring

To support my idea for building a 360 degree range finder, I want to build my own slip ring assembly.

I'm thinking of using a copper clad board to create concentric rings. I found a manufacturer that uses this technique. I posted a picture from them below.

Pablo the Pool Toy

Introduction

This is a concept for a robot to monitor and manage my swimming pool.

Design Goals

My Shopping List (feel free to ignore)

Why would you care what I'm shopping for?  Well, you probably don't.

Still here?  Go build a robot!  Here's what I'm shopping for to build some of my own.

September 2009

I need stuff for Mr. Suspense!  Plus maybe some other goodies.

My Robot Habit

My robot calls to me. 

It says, "You don't need sleep.  You need to rebuild my chassis.  It's too hard to replace the batteries, and I'm down to 4 volts here."

Just finished my own Start Here Robot

I'll post it under Robots soon.  I had to dust off a few brain cells, as it has been a long while since I've done any programming.  There are still some flukes in the code, but it runs and navigates simple scenarios.

Yeah!  I am officially a Picaxe programmer.  Thanks to Fritzl for his excellent documentation.

Emergency de-soldering braid

So I need some components from an old modem board for a new project. I'm trying to rescue a DPDT relay and an LM386 op ap for a mouse bot.

However, the soldering job on this board is really well done, and I'm having trouble.  So I need my de-soldering braid. Is it in the basement with my soldering kit? No.  I must have used it up.

Where's my old de-soldering bulb?  Lord only knows.

What to do?

Old coax cable. Strip off the outer insulation. Pull off the braid. Flaten in vise. 

There you go.
