About Me

I have been a developer for 14 years programming in Java, Groovy, Python, C#, C and several other languages. I currently work for The Babcock and Wilcox Corporation where I develop boring Enterprise Technology, specifically creating and managing customizations to a large proprietary J2EE application. In my spare time however, I work on all sorts of projects using many technologies from writing C for AVR microcontrollers to Java web based applications for automating my home. This blog is a way for me to show off my projects and how I built them.

Recently I have been spending a great deal of time CAD modeling in solidworks the individual pump units for the Mixer Elixer. I do this for two reasons. It helps me reason through the mechanical design of the pump unit. It also allows me to design the custom parts that I need for each unit. I am then able to 3d print the custom parts for each unit. Below is my current (incomplete) design for a pump unit.

Each pump unit has a single servo which drives two threaded rods connected to each other with a gear. There is also a smooth glide rod next to each threaded rod. (I have not yet learn how to model the threading) This was originally going to be hooked up to a scissor arm to actuate a syringe which would pump the liquids for a drink. I started to worry about the flexing in the scissor arm and then decided to simplify it a bit to just two beams which would transfer the rotary motion into linear motion. There are several easier ways to pump liquids for a drink machine, but I figured this design would have a sort of mad scientist feel for the laboratory.

Below is the 3d printer cabinet I built which is currently printing parts for the Mixer Elixer. I havenít yet had time to properly attach the door so I duck taped it on so that I can get my Halloween projects moving along. I will have some future blog entries on the 3d printer cabinet design. The reason for the chamber around the 3d printer is to improve the print quality on my prints. Supposedly this is supposed to help with warping.

Below is a closer picture of the bracket the 3d printer is currently assembling...

Last picture for today... The lab is in full swing for Halloween!
