[Jack], a mechanical engineer, loom builder, and avid sailor wanted an autopilot system for his 1983 Robert Perry Nordic 40 sailboat with more modern capabilities than the one it came with. He knew a PC-based solution ...
Australian Personal Computer Arduino project: USB foot-operated mouse switch Australian Personal Computer Arduino microcontrollers can easily be used to power fun projects like robots and even sending tweets to Twitter, but they're versatile enough...
Following on from my previous post about implementing MQTT-SN, I have been playing with the model and state machine to get something that works. Here are some notes, diagrams, and thoughts on the situation so far.
This project is all about creating a simple game to test your memory. I’ll be using a Teensy 3.0 board. If you want to know more about this board please click here to read a Getting Started Guide I’ve created a few days ago. This project is also 100% compatible with the Arduino.
Most sous vide cooking is done in sealed plastic bags. One exception to this is eggs, which are cooked in their shells. Other recipes (such as butter-poached lobster tails) call for the food to be immersed directly in the cooking liquid. To make the sensor safe for contact with food, cut a length of food-safe heat shrink tubing and shrink it around the sensor as below.
This is a long delayed post. I am glad I finally finished making a video for it, and it’s time to introduce SquareWear 2.0 — an open-source, wearable Arduino microcontroller board. At heart, SqureWear 2.0 is an Arduino running at 3.3V and 12MHz. It has built-in mini-USB port for uploading programs, charging lithium batteries, and creating a serial communication channel. It comes with a lot of useful built-in components, such as a color LED, a general-purpose push-button, a buzzer (yup, you can make it sing a tune), light sensor, temperature sensor, three MOSFETs (to drive high-current load).
Looking for a first project to try out on a Raspberry Pi, I though what better than a Spectrum Analyzer? (Sometimes this display is erroneously referred to as a graphic equalizer--that let's you change the sound, not display it)
We all know that wearable computers will need to be small and Intel has obliged by unveiling Edison, a new computer housed inside and SD card that has built-in Wi-Fi connectivity and that can support multiple operating systems.
After many student-day years messing around with Arduino boards, then migrating to PIC microcontrollers, before returning to AVR chips, I found that t... (Make your own Arduino testing board! made at Techshop!
My latest project involves a candy dispenser from Sharper Image. I found the dispenser at Goodwill and bought it for $2.99. It didn't work as originally designed but that wasn't a problem because I wasn't planning on using as it was designed.
Eben Upton hits back at claims free Raspberry Pis aren't being used (If you were furrowing your brow at some press comments about us from Fri, here are actual stats on why they’re wrong: http://t.co/HEKsO1eSe9)...
So this is to announce a new “DIJN” series of weblog posts, describing how to set up your own Wireless Sensor Network with JeeNodes, as well as the infrastructure to report a measured light-level somewhere in your house, in real time. The end result will be fully automated and autonomous – you could take your mobile phone, point it to your web server via WiFi, and see the light level as it is that very moment, adjusting as it changes.
Gregory Crawford's insight:
The entire JeeLabs blog is a "must read". Informative, fascinating, well written, and wonderfully documented.
