With its complete power management and long-range ISM radio, Ardhat + Raspberry Pi are perfect partners for building IoT systems.
Ardhat is Moteino compatible,  so you can hit the ground running

I made a simple temperature & humidity monitoring system with a little modifying Adafruit project(https://learn.adafruit.com/dht-humidity-sensing-on-raspberry-pi-with-gdocs-logging/overview). I know it is nothing new, but I just made it for monitoring the temperature and humidity in my home, especially for my baby son :) I already upgraded the sensor from DHT11 to AM2302 and a function to notification to my Android phone, and planning to use SQL DB or Splunk rather than Google Docs.

요즘 개인적으로 진행 중인 프로젝트. 이름하여 사물인터넷+빅데이터 홈 오토메이션 프로젝트. 사물인터넷에 빅데이터를 접목시켜서 보다 나은 집안환경을 만드는 프로젝트다. 요즘 워낙에 이슈화가 많이 되어서 더이상 새로울 건 없지만 요즘은 생각하는 것보다도 실천하는게 중요한 시기인 듯 해서 학교 공부에 연구 프로젝트에 시간 내기가 정말정말 힘들지만 틈틈이 진행 중이다.
지금은 그저 집안 온도/습도를 측정해서 데이터를 내 개인 구글 문서에 기록하는 정도 뿐이지만 나중엔 SQL DB나 Splunk같은 빅데이터 플랫폼을 적용, 가습기 및 히터/에어컨을 자동으로 작동시키는 기능과 인터넷으로 일기예보를 읽어서 미리 온습도를 조정하는 기능도 추가할 생각중. 또 다른 의견 있으면 주시면 감사~
The project that I am currently working on in personal, AKA IoT+Big Data Home Automation project. It is not new recently but it is more important to do it rather than just think.
Now it just monitors temperature and humidity and send it to Google docs, but later I am planning to apply SQL DB or Splunk, control a humidifier and a heater/cooler, and control in advance with forecasting. It's welcome to give me any other ideas~:)

Oh, it is replicator, not a simple USB hub.. that makes more sense.

Upgraded the humidity and temperature sensosr from DHT11 to AM2302, much more accurate one(DHT11 was just a kind of cheapy...), and it can send a notification to my Android phone:) Next step is to make it turn the humidifier on or off if humidity gets lower than I set and use SQL DB or Splunk rather than Google Docs. Welcome to give me any other ideas!

온습도 센서를 더 정확한 걸로 교체하고, 온도나 습도가 너무 높거나 낮으면 내 폰으로 푸시 알림을 주는 앱을 만들었다. 다음 단계는 습도가 너무 낮으면 자동으로 가습기를 작동시키는 시스템 구축~

Since the S7-200 is a bit different then the newer S7-1500/S7-1200 PLCs it took a bit of work to get it working. The python-snap7 library was missing the connection method for the old TSAP method of connecting. So I forked th...

I'm trying to listen for continuous keyboard input and do something while certain keys are pressed down. Eg. if 'w' is held down, then run the forward() function.

I've linked my code here, but it doesn't seem to work. Can anyone point any mistakes and/or give me ideas to achieve what I'm trying to do?

SpirallLED uses Arduino code from http://bit.ly/messagetorch and Raspberry Pi DMA code by Jeremy Garff to create a '3D' display from a string of SmartLEDs without cutting them.
http://bit.ly/spiralled     #arduino    #raspberrypi   #ardhat   

[If you don't have your Ardhat yet :) , you can use this code on a standalone Pi with an external supply and through a 5V level shifter on the PWM pin]

Just got this working with a RasPiO Duino (programmed with a Pi and the Arduino IDE, of course). Thought it was pretty good fun. It's an old QDSP6064 7-segment display you might have found in a pocket calculator in the 1970s. You can get them from Pimoroni and Sparkfun do some great tutorials and software libraries. Everything worked first time :) Love it when that happens :)

Hi All,  I'm looking for a little project to play around with on my RPi 2.  I need a database and some means of putting webforms on top of it.  Basically, I'm looking for something like Oracle APEX (only, obviously, lighter) on the Rpi 2.  Everytime I start searching I ended up dropping down rabbit holes.  Thought I might tap into the Hive Mind here and see if anyone had any suggestions.  Thanks in advance!
Build applications using only your web browser. Oracle Application Express enables you to design, develop and deploy beautiful, responsive, database-driven applications using only your web browser. See how you can take advantage of this fully-supported, no-cost feature of the Oracle Database.

+Mohan Sundaram thanks for the advice. Node.js has come up several times in my searches, I must admit to being completely ignorant of it. I'd have to learn it from the ground up (which I'm not averse to, it would just slow the project down).

I've found a few promising looking alternatives, but whether or not they would be able to squeeze into the Pi is a different matter.
