  • Farevalue Final Prototype
  • This past summer we were really busy prototyping a smart, enhanced store value card capable of powering up an e-paper display, for a socially-focused urban planning company called Urbanscale. This is the final working prototype we engineered and fabricated together with our engineer wizard collaborator Todd Bailey and was meant as a feels-like, looks-like, works-like […]

  • GROUND Lab in Tanzania
  • In January of 2011 GROUND Lab traveled to Tanzania to visit the island of Zanzibar and to assess network coverage on the island and mostly on mainland where the lions migrate to, after they leave Kenya. While in Zanzibar we ran tests to collect GPS data from that area using different cell carriers in Tanzania. […]

  • Device X v 0.3
  • We have been really busy and excited at the Lab because we are now finishing the first full version of the prototype for the mobile health device for health clinics in Uganda in partnership with UNICEF. New prototype. New prototype on, example of a menu screen with ATM style buttons. This version, finally includes all […]

  • GROUND Lab on OpenSource.com Part 3
  • OpenSource.com, a wonderful online resource for everything open source related, asked us to share our thoughts about how the open source approach influences and affects our business model. In the third part of this analysis Justin shares his thoughts on how open source can be successfully applied to many fields such as wildlife conservation and […]

  • GROUND Lab on the Arduino Blog
  • Thanks a whole lot to our friends at Arduino for posting about GROUND Lab’s recent trip to Kenya and Tanzania to test their latest development in the open source lion tracking collar project. One of the tests involved using an Arduino Mega board to test out the GPRS connectivity and speed of local cell-phone networks. […]

Since one of the most important things we learned from the experience of testing a datalogging platform in health clinics in Uganda was that paper records were very important but also very limiting. The current paper logging process is painfully time consuming and requires lots of time spent processing the data and sending the data to its locations, which causes dangerous delays. The cell phone data collection processes used on mobile phones does not offer an option to print the data instantly, and this seemed to be a really huge issues for health care workers and volunteers currently employed in mHealth projects.

In a very short amount of time, leveraging a lot of our existing knowledge, we built a first prototype of ‘attachment’ to any regular Serial thermal receipt printer and compiled some of the most basic functionality the device needs to have in order to properly control the printer mechanism, and this is a small demonstration video of the first prototype of a GSM logic board we designed (open source) attached to a regular off-the-shelf thermal printer during its initialization routine.

And here’s a demo video of the device receiving an SMS text message and printing its content on the printer.

And here’s a video of the basic syntax of the device. In fact, typing the format “P#” means “Print # of copies”. P2 Hello World! will tell the device to print the body of the SMS message twice, as you can see here.
