All this month we’ve been posting about open-source hardware, some of the folks who make and share it, and some open-source hardware history. Today’s post is an example of wanting to build something, but not wanting to sell or manufacture it. However! What if you still wanted to share it? Open-source hardware and software, allows you to scratch that itch and avoid being on the hook for actually mass manufacturing something.

Some artists want to make the art and have others distribute it as an efficient and interesting form of expression which in itself is the art. Others want to make art that must and only be viewed in a gallery. And others just want to cause some problems and make you think.

10 years ago we tried to make an open source flash light to make us puke (video) –

“Do-it-yourself Handheld LED-Based Incapacitator: THE BEDAZZLER… Ladyada and Phil Torrone have just published an open source “Homeland Security” project, a non-lethal LED-Based Incapacitator: THE BEDAZZLER. After attending a conference where the $1million “sea-sick flashlight” (THE DAZZLER) was demoed by Homeland Security, the duo decided to created an under $250 version and recently released the source code, schematics and PCB files.”

Check out our full guide, and blog post from 2009.

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 opensource@adafruit.com, we’ll be looking for, and using the tag #OHM2019 online as well! Check out all the events going on here!
