The Connector Zoo: I2C Ecosystems
I2C is a wonderful interface. With four wires and only two GPIOs, you can connect a whole lot of sensors and devices – in parallel, at that! You will see …read more Continue reading The Connector Zoo: I2C Ecosystems

This Box Counts Your Blessings For You
It’s that time of year again when production in Shenzhen grinds to a halt. Lunar New Year has kicked off the annual month-long Spring Festival, and the whole country has taken time off to be with family and celebrate. One tradition of Spring Festival is that everyone gives each other …read more

Corporate Badgelife: Oracle’s Code Card
We tend to think of elaborate electronic conference badges as something limited to the hacker scene, but it looks like the badgelife movement is starting to hit the big time. Now even the “big boys” are getting into the act, and pretty soon you won’t be able to go to a stuffy professional conference without seeing a sea of RGB LEDs firing off. We’ll let the good readers of Hackaday determine if this means it’s officially post-cool or not.
[Noel Portugal] writes in to tell us about how he created the “Code Card” during his tenure with the Oracle Groundbreakers …read more
PobDuino Makes the Most of Grove
The chassis of a toy robot serves as the base of a robot built by [Jean Noel]. Called #PobDuino, the robot features two Arduino-compatible boards under the hood.
First, a Seeeduino Lotus, a Arduino board peppered with a dozen Grove-compatible sockets. The board, which is the size of an UNO, is mounted so that the plugs project out of the front of the robot, allowing ad-hoc experimentation with the various Grove System modules. Meanwhile, a custom ATmega328 board (the PobDuino) interprets Flowcode instructions and sends commands to the various parts of the robot: servos are controlled by an Adafruit servo …read more
An Interactive Oasis At Burning Man
An oasis in the desert is the quintessential image of salvation for the wearied wayfarer. At Burning Man 2016, Grove — ten biofeedback tree sculptures — provided a similar, interactive respite from the festival. Each tree has over two thousand LEDs, dozens of feet of steel tube, two Teensy boards used by the custom breath sensors to create festival magic.
Grove works like this: at your approach — detected by dual IR sensors — a mechanical flower blooms, meant to prompt investigation. As you lean close, the breath sensors in the daffodil-like flower detect whether you’re inhaling or exhaling, translating …read more
My Life in the Connector Zoo
“The great thing about standards is that there are so many to choose from.” Truer words were never spoken, and this goes double for the hobbyist world of hardware hacking. It seems that every module, every company, and every individual hacker has a favorite way of putting the same pins in a row.
We have an entire drawer full of adapters that just go from one pinout to another, or one programmer to many different target boards. We’ll be the first to admit that it’s often our own darn fault — we decided to swap the reset and ground lines …read more
