Parallax Open-source hardware #OHM2019 #oshwa @ohsummit #opensource #opensourcehardware @opensourceorg @ParallaxInc


Without Parallax, I do not think many/most of us would be here making and selling electronics, from being one of the first companies to bring electronics to educators, to being a pioneer for some many efforts and products in the world of educational electronics. Additionally, many of their products are made in the USA.


First up, who is Parallax? …. Wikipedia

Parallax Inc. is a privately held company in Rocklin, California. Parallax Inc. designs, manufactures, and sells BASIC Stamp microcontrollers, Propeller microcontrollers, microcontroller accessories (such as LCDs, sensors, RF modules, etc.), educational robot kits, and educational curriculum. Parallax is headquartered in Rocklin. The Rocklin office employs thirty-five people in research and development, sales, manufacturing, education, marketing, and technical support. Parallax Inc. has over seventy distributors around the world

And also check out the Parallax about page with more details and history of Parallax. They’ve been making electronics since 1986!


What else? Parallax released the Propeller 1 Verilog Hardware Description Language source code. If you’ve ever wondered how the Propeller chip actually works, this is it.

Parallax was one of the first companies that was doing educational electronics to start to release their files and more, specifically under open-source licenses.


There is an entire section devoted to Open Source Designs, which include…

  • Propeller 1 (P8X32A) Multicore Microcontroller Design Files.
  • Parallax Printed Circuit Board Hardware Designs.
  • Propeller Object Code.
  • And Open-Source Software Projects.


One other note, we THINK Parallax was one of the first companies to put the open-source hardware gear-community logo on packaging for retail use, we have a post about their packaging but will see if we can find the back with the logo.




And here’s some of the Parallax products/project we’ve either stocked or did projects with too.


Open source hardware month @ Adafruit:


October is open-source hardware month! Every single day in October we’ll be posting up some open-source stories from the last decade (and more!) about open-source hardware, open-source software, and beyond!

Have an open-source hardware (or software) success story? A person, company, or project to celebrate? An open-source challenge? Post up here in the comments or email, we’ll be looking for, and using the tag #OHM2019 online as well! Check out all the events going on here!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Join 35,000+ makers on Adafruit’s Discord channels and be part of the community!

Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

Join us every Wednesday night at 8pm ET for Ask an Engineer!
