- August Hardware & Electronics Engineering Meetup by MacroFab & Mouser Electronics event is live! Come grab some food, beer, and socialize if you’re in the Houston area.
- Joseph Broms
- Joe received his B.S. at the University of Illinois in Computer Science
- He has worked in numerous industries including, medical device, security, professional audio, broadcast, and education
- One central theme to Joe’s career is successfully turning ideas into sellable products
- Has worked on many projects ranging from an FDA-approved cardiac simulator to a critically acclaimed instrument tuner, APTuner
- Joseph is releasing a product called ProtoBricks on Indiegogo
- Protobricks are LEGO-compatible building blocks to lower the entry-level of how electronics work
- Purpose is to remove how much ancillary gunk is needed to understand how it works
- It has been Joesph’s hobby for the past seven years with many different revisions
- Mold design and plastics
- LEGO stud pitch is 7.986mm, 2.54mm on solderless breadboard = exact factor of pi difference
- Used modified LEGO bricks as initial tests
- 3D printing has gotten good enough to prototype injection molding
- Electrical Contacts
- Copper tape and sheets pressed into the plastic did not work
- Spring-loaded pogo pins everywhere!
- QUANTITY DICTATES EVERYTHING
- Protobricks are LEGO-compatible building blocks to lower the entry-level of how electronics work
- Stephens Game – Room for balloons. How do you get rid of them?
- Joseph – Blowtorch
- Stephen – Pull a vacuum on the room
- Parker – Throw cats into the room
- Combination – Flamethrower vacuum cat

About the Hosts
Parker Dillmann
Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.
In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.
In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.
Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.
Stephen Kraig
Stephen Kraig began his electronics career by building musical oriented circuits in 2003. Stephen is an avid guitar player and, in his down time, manufactures audio electronics including guitar amplifiers, pedals, and pro audio gear. Stephen graduated with a BS in Electrical Engineering from Texas A&M University.
