Raspberry Pi Weather Station

 

Yes you can purchase weather stations that are ready to go but where is the fun in that? The Raspberry Pi Weather Station is designed for people who like to take control of their technology. 

 “WeatherPi is a solar powered Raspberry Pi WiFi connected weather station designed for Makers by SwitchDoc Labs. This is a great system to build and tinker with. All of it is modifiable and all source code is included. The most important functions are:

  • Senses 20 different environmental values
  • Completely Solar Powered
  • Has a full database containing history of the environment (MySQL)
  • Monitors and reports lots of data on the solar powered system – great for education!
  • Self contained and monitored for brownouts and power issues
  • Can be modified remotely
  • Download your data to crunch it on your PC
  • Can be modified to do SMS (Text) messaging, Twitters, webpages and more
  • Has an iPad Based Control Panel”

DIY Home Automation Box

DIY Home Automation Box

 

If you have a spare Arduino that is looking for a purpose this DIY Home Automation Box might be something interesting to build. 

“A DIY project that is a home automation box created with what as brains but pcduino and arduino combo. Nice! This home automation box allows the maker to turn on or off the lights in a room or select color of a hacked oil diffuser (the oil diffuser also created by the maker and made compatible to this project), project the indoor or outdoor temperature and humidity ratings from an arduino node by using RF transmission 433Mhz or create the simple handle for alarms. Like any other amateur DIY, this one too leaves plenty of scope for your imagination.”

Arduino Gas Sensor Project

Arduino Gas Sensor Project

 

Eric William made a Gas Sensor Project that uses an Arduino to send out spoken words to a cheap transmitter that can send the current levels of the sensors direct to a radio. This is a very adaptable idea that could be used for many things, best of all the parts of the project are very affordable!

 “Using the Arduino I was able to easily measure the gas levels. Using the Talkie library I was able to then translate these values into true synthesized human voice (with NO special boards/modules) The transmitter accepts the voice output and directly transmits it out on 433mhz to ANY receiver. It is sending this as an AM transmission- but surprisingly any FM receiver such as scanners/handy talkie radio, ems radios etc have no trouble receiving the clear voice values.”

This Robot Bug is very elegant. It has an Arduino for a brain and PING sensors for the eyes. 

“Software is quite straight forward, a giant state machine, that takes input from the sensor, every now and then. halfbug has 5 different movements, one regular forward movement, one turn (left and right) and one turn hard (left and right). In addition to that halfbug has a head movement (left-right-straight) or looks left when turning left. Both, leg and head movement is controlled by separate sub-state machines.”

Bug Zapper Illuminated Bike

 Bug Zapper Illuminated Bike

 

Steve from Rimstar.org has build an illumination system for his bike. Most of us would use a battery and a light right? Well Steve is using the bike power to generate thousands of volts and spark gap to warn people that a bike is coming. It has the added benefit of keeping people from wandering too close to the front of the bike!

“Want to make your bike create sparks as you drive?

One way I found is to add on a Wimshurst machine, an electrostatic machine that produces sparks. The cool thing is that the Wimshurst machine works by rotating two disks, normally using a hand crank… but connect it up to your bike pedals and now you rotate the disks as you pedal! To make it cooler, this one even uses a 3D printed sprocket!”

Capacitive Touch LED Table

 

This Capacitive Touch LED Table by uses an arduino to drive a neo pixel strip and uses the capacitive touch library to allow the aluminum trim to become a mode switch. The code is available to you can build your own if you like. She cut a hole in the top of an old table and mounted the electronics under glass. Looks great and the effects are nice.
