Semaphore-Bot v3.1

Version 3.1



Semaphore-Bot 3.0 never saw an audience because his arms were too long/heavy for the motors. Last minute design change later, v3.1 was born.

A few thoughts on the review:

While I agree that the design/construction of the bot needs to be cleaned up a bit, and I may have to reconsider how I approach the flags, I think too much of my review was spent discussing the bot himself.

The piece is as much about the robot as a webpage is about the computer or a phone call is about the phone.

Before I next show it to people I really do need to finish the complete installation, that means create the key cards so that people who are intrigued enough by the motion will try to assertain the message. This will also give a hint as to the meaning of the flags.

On the subject of "why semaphore / why flags?" As far as I know semaphore is the most reciever invested means of communication. Maybe morse code is equally or more so... Morse code is definitely more recognized... this may require exploration.

One happy accident during the critique was a set of loose screws, combined with the occasional contact between arms caused one of the gear boxes to fall apart. While unintentional, this definitely falls in line with my thesis that the load of modern communication is destroying the value of communication itself. (The bot is communication incarnate.)

Triumph Breakfast

Saturday morning I woke up after a little over 12 hours of sleep. It was wonderful. Since I got back in town Monday I'd been sleeping 2-3 hours a night on my couch (knowing full well that if I slept in my bed, there would be no waking me). I'd get home at 5 am, crash, wake up at 8, and go back to the studio.

Toward the end of the week the combination of lack of sleep, and poor eating habits were really getting to me. I was moody, and at times a careless (see: I had a mental lapse and grabbed the hot end of a soldering iron.)

But it was all worth it. I got my piece finished in time and went through a fairly successful review. A lot of questions were posed that I wouldn't have thought of otherwise, and some fabrication errors presented themselves to bring a possible new direction to the project.

When I woke up Saturday, I decided it was time to celebrate. And in my world, there is only one way to celebrate: food. So I made spinach bacon eggs benedict!

Start with fresh home made biscuits, topped with spinach sauteed in white wine:

Biscuits topped with spinach

Add a couple strips of bacon:
Bacon!

Next: 2 perfectly poached eggs (ie: yolks still soft)
Mmmmmm

And finally coat in hollendais sauce:
Look at that!
(I let mine sit about 5 seconds too long and it started to curdle. Unfortunate, but still delicious.)

Soooo good.

My first contribution to the Arduino Playground

The Arduino: Playground has given me so much that I felt it was time to contribute back.

So I wrote this article: Arduino + PERL

Blogger Upgrade

Apparently blogger upgraded one of the backend pieces of their atom / rss feeds, migrating from OpenSearch 1.1 to OpenSearch RSS 1.0.

There aren't a lot of people this really effects, but since this blog is driven by a blogger feed, it screwed with me for a second.

Foul Mood?

I recommend maple bacon

Thanks for curing my grumpies Voodoo!

Semaphore-bot v3.0.alpha


Untitled from Andrew Parnell on Vimeo.


Semaphore-bot 3.0 is on its way!

I went through and rewrote the control code from the ground up in PERL, letting me eliminate processing from the equation all together and making everything run more efficiently.

I also built some gear boxes so that I no longer need to stack servos.

All in all, major improvements all around.

Tomorrow I rebuild the casing and get it ready for show.
