• Eagle : Export PCBs quickly with this script  |  2018 Sep 24

#electronics  #elecFab 

Exporting image files for milling PCBs is a tedious operation. Fortunately, Eagle has a built-in scripting interface. Customized scripts, spanning multitudes of operations, can be launched from the file menu. The following script, based on this one, will output two PNGs, one for traces and the other for the outline and holes. The PNGs can then be coverted to milling tool paths via Fab Modules. DISPLAY ALL; RATSNEST; DISPLAY None; DISPLAY Top Pads Vias; SET DISPLAY_MODE NODRILL; SET PAD_NAMES OFF; SET PALETTE BLACK; EXPORT IMAGE /*/pcb_traces.png MONOCHROME 1500; DISPLAY None; SET DISPLAY_MODE REAL; DISPLAY Pads; EXPORT IMAGE /*/pcb_outline.png MONOCHROME 1500;...


• Environmental monitoring with online data logging to Thingsv  |  2018 Mar 31

#coding  #electronics  #pureImagination  #microCode  #comm 

Over the past few months, I have continued to develop the electronics and programming aspects of this project. I now have a system for evualating power potential and environmental sensing, and logging all that data online to Things Speak, an open Internet of Things Platform. Previous to using Things Speak, I was logging data to an SD card. However, with an SD card, I need to periodically pull the data from the card. Extra work. Using Things Speak, the data is available to me and everyone else instantly, everywhere. There have been some issues with wifi stability and internet connectivity...


• Distributed Version Control : GIT  |  2018 Feb 14

#coding  #pm  #tutorials 

Git is an actively maintained, free and open source, distributed version control system originally developed in 2005 by Linus Torvalds (Linux). Distributed version control systems help software development teams collaborate on projects' source code by maintaining a full history of file changes across a decentralized file system. The distributed architecture maintains a full history of all changes in every developer's local working directory, aka repository. Redundancy. Git is flexible. Git works across all platforms, supports branching and tagging as first class citizens and operations within, such as merging or reverting. Open sites such as GitHub or GitLab are fantastic for...

• Inventory  |  2017 Jun 28

#pureImagination 

Following is a list of prices and quantities for the second prototype Pure Imagination build. Many of the materials, ie. acrylic, electronics were donated to the project from the fablab, others as part of the Fab Academy inventory/ session resources. For those materials, I checked online sources. The most expensive parts of the build are the chemical components and, shockingly, the silicone for the concrete mold. The silicone mold survives however, and that price would "decrease" with each successive cast. The bioelectrochemical system needs to be optimized for electricity output and material cost, perhaps alternative materials could be found for...

• Hessian/ burlap/ crocus composites  |  2017 Jun 28

#composites  #pureImagination  #mold 

To make the composite surface, I will combine hessian with a two-part resin which takes about thirty minutes to set and five hours to cure. This job is messy business and I did not have gloves or time to get gloves. That was a bad idea, first, not many photos. Second, the resin gets very hot in just a few minutes, trial by fire. Finally, it is nearly impossible to get off your hands. After countless soapings, I resorted to scrubbing my hands with coarse hair brush/ soap combo and then wearing (different) gloves for the next few hours because...
