“Finally got the linebot working reliably. I’ve uploaded 3 images and a movie. I also included the modified Arduino script provided for the “method 1” servos and “V2 Adafruit_Motorshield” I’m using. My sensor board image shows the original 5 sensors described in your “Arduino Robotics” book, but you’ll notice now only the three middle sensors have signal wires, to match the 3-sensor script you provided. “

“I’m always looking out for new ways to add more shields and components to my Arduino, and this felt like a natural experiment, so I gave it a shot: it’s an Arduino, Potentiometer, accelerometer, compass, Lithium Backpack, and TouchShield Stealth wired through a fairly large turkey :)”

“At first a few months ago I saw this Veear EasyVR speech recognition module, and I bought one on ebay because it looked pretty cool. When I got it I thought it might be a cool idea to control my room with it, and the idea was born to make my bedroom controlled by voice!”

“I’ve been working on creating a cheap, time-lapse camera that people could use to ‘sense’ the world around them. The cost of such a device would be around $10, when all is said and done, and having multiple of these devices would open up options for public computing that people have not considered – a world where people are willing to deploy “personal, public” electronics throughout their environment with the same ubiquity, recyclability and reusability as paper.”

“9 Volt batteries extensively used in various electronics measurement equipment. Powering these devices with rechargeable batteries can be a cost effective solution. In this post a simple Lithium-ion 9 Volt Battery Charger design with overcharging protection will be presented. Charger is based on PIC16F876A microcontroller and uses its A/D module to monitor current flow into the battery.”

“The Shuttle XPC has one major limitation when it comes to accepting two PCI-Express devices when one of those is your typical double-slot graphics card. Although you can find single slot cards these have a tendancy to either be economoy cards or ones that require additional cooling with water. “

“The temperature and relative humidity of indoor air is an important parameter that can influence indoor microbial survival, abundance, and community structure. Temperature and relative humidity can also be used to infer other information about indoor environments, such as whether or not it is being heated or cooled.”

“Stubby is an evolving hexapod robot which I am making, with contributions from my 6 year old daughter and a co-worker. I have long wanted to make a walking robot, thanks to shows like Stargate SG-1. While Stubby is not the same, it has been a very entertaining and educational project to work on.”
