The ESP8266, wow, I'm impressed, such a cool LITTLE device. 32-bit processor, lots of RAM, lots of storage, WIFI, serial port, and 3.3V.
I've managed to get a couple of the Arduino demos working with it, it's not what you think, Arudino 1.6+ has support...

If you are a developer and you work in public hotspots you have indoubtable ran into an issue where you try to pull down a repository from Github through the
git:// protocol and you get this error:

I've finally did it. I got the Da Vinci 1.0 and the E3D hot end working. Well it isn't the E3D, but a Chinese clone working. I've decided to use a different method than I described in my Da Vinci 1.0 E3D Conversion post.
The first thing that I changed...

One neat trick that I found out about Capistrano 2.0 was the ability to run sequenced tasks via the command line. An example is this blog, first I run
bundle exec cap build then
bundle exec cap deploy. I don't want to add the
build task as a dependency...

With me getting the lazy susan setup for the XYZ Da Vinci 1.0, I've finally started to work on the motherboard side for the E3D conversion. I've also got the new stepper motor installed, but need to finish up the new wiring of the printer.

Newest modification is a lazy susan roller bearing to spin the Da Vinci printer around my table. The table that I'm currently setup with only allows access to the printer from the front. My solution to this issue is to install a cheap Lazy Susan roller...

I've in the process of converting my Da Vinci 1.0 over to a E3D. I'm going to use a bowden extruder and I didn't want to modify much of the existing extruder setup, so I ended up buying an extra stepper from RobotDigg to use for the conversion.

I've been tring to get into the performance groove lately and understand the memory allocations that occur in our Ruby applications. This has lead to look into using
jemalloc to reduce fragmentation. There has been many discussions on the positives...

I've been working on a project to reverse engineer a keyboard matrix. This keyboard came from when I used to volunteer for FreeGeek back in college. The controller board was long gone, but the pins were still there, so interfacing with AVR was rather...

At my employers we recently switched from using Google Hangouts to using Slack. We like the power it gives us with the ability to extensionize it. So for the first extension, I've decided that it would be nice to keep everyone in the loop with recent...
