The Simplest SMT Component… In The World
Stephen’s CNC steps closer to being completed! Parker receives a newsletter that has the simplest SMT component in the world.
Taking Pictures with Magnetic Flux
Two major topics this week! Major Box Truck updates and a flashback when Parker was introduced to digital photography through the Sony MVC-FD5.
We discuss the different seasoning, boil and soak times, and building an inexpensive boil pot from materials and supplies Stephen already has.

- Our Guest this week is Kwabena Agyeman who runs OpenMV (Figure 1).
- The OpenMV project is about creating low-cost, extensible, Python-powered, machine vision modules and aims at becoming the “Arduino of Machine Vision” (Figure 2).
- Parker is using an OpenMV camera for the first iteration of the Semi-Automatic Inspection Machine.
- The great thing about Open Source is that you can fix bugs.
- OpenMV started as a Kickstarter.
- The original OV2640 Omni Vision camera sensor was discontinued and gray market parts where found but didn’t work. Replaced with the OV7725.
- KeySniffer sniffs cheap wireless keyboard protocols. We should take a page from BSG and go all wired to prevent Cylon infiltration.
- Facebook has a new Area 404 Hardware division. Could see some interesting hardware come out of this? Possibly similar to Bell Labs of ole?
About the Hosts
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 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.
