Featured Adafruit Google+ Community Project
(Note: Google+ login required.)
Many thanks to Russell Miller for sharing his Door Access Device project this week in our Community! Russell includes a detailed explanation of the project and says he’ll post the code up on github eventually.
This is a door access control device I’ve been working on – it’s actually complete now, I just have to figure out some programming edge cases so it’s reliable.
Its core is a cheap power supply from one of those ebay keypad systems. It’s the box on the right. To the left is an arduino yun with a custom shield, with a DC-DC converter on the bottom so the Yun doesn’t fry (I already fried one). The terminal strip on the bottom handles internal connections, the one on the top connects to the door strike and RFID reader. (read more)
Featured Community Project from the Adafruit Blog
Chuckz shared an awesome antique piece of engineering project his father made on the Adafruit Forums!
I was looking at a home made electric motor made by my father made out of wood, metal and wire.
Where did hobbyists get their electronic parts before 1921 or 1892?
The middle is actually a nail if you had not noticed.
I always looked at the parts as a piece of junk but the engineering is more important than looks.
I wondered where people got their parts before Radio Shack, General Electric and RCA.
