These Beautiful Electronics Pinout Diagrams Make DIYing a Little Easier

Thu, 07 Feb 2013 09:52:51 +0000

When you’re first getting started learning how to make your own electronics with the likes of Arduino, the process, pins, and everything else is a little confusing. Arduino forum member Romano d’Ezzelino wanted to make things a little easier, so they designed a simple pinout sheet to track where all the power goes.

I love it when someone takes the time to teach a broad audience something that most people who work on computer systems should now but probably don’t understand very well. Thanks SparkFun! [youtube https://www.youtube.com/watch?v=JJZOTtwpAjA&w;=560&h;=315]

Installing Google Go on Ubuntu 9.10 x86

Tue, 10 Nov 2009 21:38:15 +0000

This is for x86 processors. You need to change the 386 to amd64 if that’s your chip architecture. First create a bin directory in your home directory if you don’t have one already:

mkdir $HOME/bin

Then edit your .bashrc file and add:

export GOROOT=$HOME/go
export GOOS=linux
export GOARCH=386
export PATH=$PATH:$HOME/bin

Then reread your bashrc file:

source .bashrc

You’ll need some packages installed to build it:

sudo apt-get install bison gcc libc6-dev mercurial

Now check out the code and build it:

Infrared Sensor Data for Hal

Thu, 08 Oct 2009 15:01:31 +0000

I’m using an infrared range sensor for the real life Hal. The Sharp GP2Y0A02YK0F - Infrared Proximity Sensor Long Range -

[caption id=“attachment_498” align=“alignnone” width=“300” caption=“Hal 1.0”][/caption]

While testing his motions, I was noticing some pretty erratic behavior, so I decided to collect some data on the sensor values on a fixed object, while Hal was not moving.

This is a graph of about a minute of Hal moving the sensor from 45 to 135 degress in front of him and then taking a reading when the motion of the sensor stops. It’s at a wall, at a slight angle so the graph lines aren’t on top of each other at about 45 centimeters away.

I should know better than to leave home without paper and a pencil

I’ve been doing a lot of writing lately. I gave myself a deadline of today to finish an article I’ve been thinking of for a week and spent the whole day having writers block. As soon as I walked out the door to pick up our Chinese takeout for the evening, 100 ideas came swarming into my head. In my Jeep was a pen, but I cleaned it over the weekend and there was not a scrap paper in sight.

How to not bork up your startup

Tue, 01 May 2007 14:49:34 +0000

So you’ve done it. You quit your job and are working 18 hour days on a new venture. It’s great, you’re doing what you want, you’re scared and excited. It’s great.

You add some people to help. They are a virtual team because the best people out there don’t have to move to be part of the team and you want the best.

Then you loose your original vision in feature creep.
