Spotting Arduino Clones

Arduino Clone Board

Open Source Hardware (OSH) means not only releasing devices, but all of the documentation associated with them. For some projects, this may include the actual CAD files used to produce the device. For example, the Arduino team produces not only schematics but the Eagle PCB CAD files for each of their boards. The great thing about such disclosure is that one can easily tweak the existing design for their own purposes. The downside is that nearly anyone can submit the exact same files to their own production house and have immediate clones.

Flickr changed their API, so the callouts are gone…. Sorry about that. -James

Even when some people choose to do this, as have some eBay (and now Amazon) sellers, differences crop up from “real” boards and the clones (aka “fakes”). Click on the above photo for a Flickr-based “spot the differences” game!

BinBoo – Binary Clock

Status:  Completed
Hackster.io Project Page: https://www.hackster.io/baldengineer/binboo
Github Code:  https://github.com/baldengineer/BinBoo

BinBoo Binary Clock made out of Bamboo
Binary + Bamboo = BinBoo

 

Abstract

Binary + Bamboo = BinBoo.  This project is my first attempt at making a laser-cut enclosure.  Ponoko was used to cut the project which holds itself together.  The LEDs are driven by an Arduino-based clock that incorporates a RTC1307, FTDI chip, ATmega328, and TLC5940.

Binary Clock Control Board

Assembled control board. The processor is an ATmega328, RTC is DS1307 RTC, and LED driver is a TLC5904. There is also a FT232RL on the back side for USB to Serial connection, however, it doesn’t appear to be working.Next I’ll need to turn on the RTC and make sure it can actually keep time.
