[edit] Michigan Tech Open Source Hardware Enterprise

The Open Source Hardware Enterprise (OSHE) will develop open source hardware solutions specifically to address problems of our project partners, while sharing the solutions in the commons. Open source hardware consists of physical technologies designed and offered in the same manner as free and open source software.

[edit] Spring 2015

[edit] 1/19 to 2/9

Prusa i3

  • Status Update: The thermistors are on order and should be the last component needed to complete this printer. Estimated completion date: 1 week after transistors are in.
  • This is our second small scale 3D printer, which we will use to fulfill print orders for customers inside and outside of the university. The printer is nearly done mechanically, but it still needs the electronics wired up. It will also need significant calibration to get the print quality up to our standards. The members working on this project are Lucas Wilder (talk) 11:24, 19 January 2015 (PST), Tabeauch (talk) 13:49, 26 January 2015 (PST), and Mdholt (talk) 14:14, 26 January 2015 (PST).
  • Instructions for the build can be found here: http://reprap.org/wiki/Prusa_i3_Rework_Introduction.


  • The Gigabot is even closer to being finished than the i3. The only thing missing from the machine is the extruder assembly and a large print nozzle to reduce the lengthy print times. This project must be finished by the February 9th deadline. If any parts are still needed, please email Dr. Pearce and copy me on the message. Ian Peoples will be leading the Gigabot team, with Greg Chamberlain and Walker Nelson also working on the project.

Rekhi Enterprise Funding Challenge

  • Status Update: The thank you letters are written and will be sent out tomorrow (2/17). The keychains are printing, and instructions for contacting us will be sent to the large donor so that we can create their custom print. Estimated completion date: As soon as we receive a response from the large donor.
  • Last semester the OSH Enterprise competed in the Rekhi Enterprise Funding Challenge and earned around $1400. The donors must be sent their rewards according to the plan we laid out prior to the competition. The Physical Bitcoins must be prepared, and the donors who unlocked the custom 3D print reward must be contacted. In addition, each donor needs a personalized thank-you letter. This must be taken care of as soon as possible. Lucas Wilder will be working on this along with Ian Peoples and Patrick Rice.

[edit] 2/9 to 3/2

Open-Source Lab Equipment Project

  • Once the i3 and Gigabot are finished, we will be splitting everyone into teams of 3 to work on a piece of lab equipment. Each team will take either an existing open-source lab equipment project and significantly improve it, or come up with a new idea for the project. Examples of existing projecs from the last semester's Open-Source 3D Printing course can be found here: 777 OSH Science project 2014

[edit] 3/2 to end of year


[edit] Marketing and Recruiting

  • Once all 3 printers are up and running, we will start promoting our printing business hard. Michael Holt, Lucas Wilder (talk) 12:00, 19 January 2015 (PST), and whoever else is interested will work together on this.

[edit] Semester-long Projects


  • Progress update (2/16/15): Missing parts including mirror mounts, a focusing lens, and CAT5 cable have been ordered. The mirror mounts and focusing lens have arrived and need to be put together to finish the optics portion of the design. The electrical team is beginning the process of connecting all electrical components and interfacing with a computer. Known parts that still need to be ordered include: a laser water chiller. A definitive final location for the lasersaur has not yet been found.
  • This is the open-source laser cutter table that we have been cobbling together since the beginning of the Fall semester. The rest of the parts need to be either located or purchased as soon as possible so that construction can continue. Olin Johnson will be leading the project, with Steven Abramczyk and Andy Schaub also working on it. Once the i3 build is completed, one of the EE students will be assigned to the project to oversee the wiring and controls portion of the build. As always, if anything needs to be purchased, let Dr. Pearce and I know ASAP.

Induction Furnace

  • Progress update (2/22/15): The coil was shaped early in the semester and measured using a LCR meter to find the inductance of the coil. The capacitance needed to resonate the LC tank circuit in the range of 15-30KHz was then calculated. The oscillator board, and the crucible break detection circuit have been soldered and tested. On the mechanical side, the water-block for cooling the IGBT modules was modeled, parts for the water-cooling and pneumatic were purchased. A housing for the system was prepared, cleaned, and stripped of electronics.
  • This project was commissioned by Dr. Pearce himself. The team made good progress during the Fall semester, and should have the furnace melting down cans by the end of the semester. Patrick Rice is leading this team, with Olin Johnson, Lucas Wilder, Gregory Chamberlain, Walker Nelson, and Nicholas Kasza also working on it.

[edit] Grades

This semester, forward progress is the top priority. We want to be an Enterprise that people join because we get things done. Deadlines must be met. At the end of each 3 week period, the teams will be evaluated based on progress and individual contribution. As long as everyone is contributing positively, grades will be positive. However, dead weight will not be tolerated and grades will reflect that. I don't anticipate that being an issue with anyone this semester, so stay focused and you won't have anything to worry about.
