HI Capacity – MakerBot Adoption and Quick Start Instructions

Hello everyone!  I’m donating my MakerBot Thing-o-Matic to HI Capacity’s makerspace.  Hopefully it will see a lot more use than what I’ve been putting it through (ahem…. I’ve been putting it in the corner and letting it collect dust..).  To help HI Cap makers get started with this machine, I’ve put together a video that I think would help with getting started.  To tune the machine however, that may require a visit to the  Makerbot Wiki to handle all the different tweaks you can do.  If you’re interested in using the Makerbot, here’s the quick start video:

HI Capacity Arduino Night IV: Temperature Sensing

Here’s the files for a presentation that I put together for HI Capacity’s fourth Arduino night on October 11th, 2011!  To recap the night’s activities, we went through five popular types of temperature sensors that you can use with an Arduino.  Each of the sensors has pros and cons.  The major differences were in software processing, hardware signal conditioning, and temperature ranges you can measure.

The answer isn’t necessarily an obvious calculation. So for your reading pleasure, I took some time to figure out two easy paths to the answer.

GPS NMEA 0183 Checksum Algorithm

NMEA 0183 Message Format
Written by Jeremy Chan on May 23rd, 2007 for Team Daedalus

Reposted from the Daedalus Archive: While working on one of my first EE projects back in 2007, I encountered a GPS checksum which I couldn’t find an algorithm for. After searching online, I found a few forum posts on how to do it, but the directions weren’t clear. I wrote this article for those like me, who understand C better than they understand vague documentation. Continue reading
