Botanicalls opens a new channel of communication between plants and humans, in an effort to promote successful inter-species understanding.

The Botanicalls project is fundamentally about communication between plants and people. We are empowering both by inventing new avenues of interaction. Plants that might otherwise be neglected are given the ability to call and text message people to request assistance. People who are unsure of their ability to effectively care for growing things are given visual and aural clues using common human methods of communication.

It's meant to replace the existing controller board in any standard servo (~.78 inch servo width). With this board you can control a servo entirely with I2C/TWI commands rather than PWM, meaning that multiple OpenServos can be controlled with just two lines! The OpenServo firmware also offers some interesting control features, such as querying a servo with an unknown position, setting control gain discretely and on-the-fly, and even querying the destination of the actuator before it reaches it!

BSODomizer Port

BSODomizer is a small, battery-powered, mischievous electronic gadget that interfaces between a laptop or desktop and VGA monitor and flashes a fake BSOD onto the monitor at random time intervals or when triggered. Here's my (Etharooni's) port of it.

BBBoost PTH Breadboard Power Supply

This is a switchable 3.3V / 5V breadboard power supply that boosts up from a AA battery. Based on Ladyada's Mintyboost

All the JeeLabs designs are CC-By. He has some nice ideas about making Arduino clone peripherals more modular. And his boards are real purty :). Most recently the AA->3.3V power supply is pretty nice looking. If you don't feel like DIY, they're available stateside from Modern Device.


3-In-One Laser (Need someone to design driver)

I am making a 3-in-one (red, green, blue) laser and I need a driver that has these features... -driver for red diode, blue diode, and green module -individual pot for a red diode, a blue diode, and a green module to set the current -a mode for all the colors to be on at the same time -a mode for all the colors to pulse at the same time -3 modes for each color to be on separately -3 modes for each color to pulse separately

    • powered by 4 14650 batteries**
    • host has two buttons (one for power on/off, one for modes)**
    • I will pay whoever can design me a working laser driver**

I am putting this driver in a flashlight host called the Fenix TK-45. The existing driver that came with the flashlight is a circle that is 1 5/8" Wide & Roughly 1/4" Thick
