A project log for FirePick Delta, the Open Source MicroFactory

Software Topology and Theory of Operation OpenPnP is the high-level brains of the machine, that does the seemingly-simple stuff like "pick up that part" and "put it over there".  Lots of libraries and sub-systems feed information to it, and it passes information to the various motors and actuators via other libraries and software modules.  It was created by Jason von Nieda, long before FirePick Delta was st ...

TMP006 Temperature Sensor Python Library using Raspberry pi,

Are you looking for an easy way to measure the temperature of something without having to attach a sensor directly to it?  Consider using a non-contact temperature sensor like the TMP006!  This sensor reads the infra-red radiation, or heat, emitted from an object and can be easily read over an I2C connection.  With the TMP006 Python library you can now use the TMP006 non-contact temperature sensor with your ...

Invisible dog trainer

With a pressure sensor, led and speaker you can turn your Pi into an invisible dog trainer that trains your dog to get off the couch. When the dog sits on the couch, the led blinks and the dog receives the command “Get off the couch”. When the dog gets off the couch it will hear the command “Good dog”. This application was featured in the Bitreactive blog. Step 1: Install Reactive Blocks Install Reactive Bl ...

Raspberry Pi 1- Wire Digital Thermometer Sensor (DS18B20)

While searching for a simple way to measure temperature using my Raspberry Pi I came across the DS18B20 1-wire digital temperature sensor. This promised an accurate way of measuring temperature with a few wires and almost no external components. The device only cost a few pounds and it seemed too good to be true … So I bought one. Within a few minutes I was measuring the temperature with it. It is so simple ...

Raspberry pi 2 water alarm with t cobbler plus

This is our first try with the raspberry pi 2 We wanted to create an headless water alarm Parts used: Raspberry Pi 2 Funduino water sensor 1k resistor Red Led Adafruit T-cobbler Plus Large breadboard (too large ;-p) Step 1: Setup of the PI 2 We only had one screen for 6 people. This meant we needed to create an terminal session to the Pi. We used putty and filezilla. The installation could only be performed ...

Cycle Chaser

Project animations from the rear of your bicycle. The framerate depends on the speed you are moving at. A couple years ago, I created a dynamic bike headlight with a Raspberry Pi and a small, battery-operated projector. I’ve been eager to explore what else I could do with a projector and a Raspberry Pi on my bike, so I created the Cycle Chaser. Made purely for fun, the Cycle Chaser projects animations behin ...

Laboratory ‘Weather Station’

This article describes how to make a network enabled weather station that may be used to monitor ambient air temperature, humidity, and barometric pressure in the laboratory. Usage Example When conducting experiments on the rotating turntable in the GFD laboratory it is often desirable to keep the mechanical forcing very small in order to operate in a low Rossby number regime. These experiments can be compl ...

Controlling an Effect with Real Sensors

For this lab you need your Satellite CCRMA kit, a laptop computer with Ethernet adaptor to program it, and some headphones with a mini 1/8" (2.54mm) stereo jack. You are also invited to bring the following optional items, but they are by no means required: Some of your favorite breadboardable sensors and LEDs. A set of small, battery powered speakers with 1/8" (2.54mm) jack. Note: In this lab, the images wi ...

Reading Analogue Sensors With One GPIO Pin

Unlike some other devices the Raspberry Pi does not have any analogue inputs. All 17 of its GPIO pins are digital. They can output high and low levels or read high and low levels. This is great for sensors that provide a digital input to the Pi but not so great if you want to use a sensor that doesn’t. For sensors that act as a variable resistor such as LDRs (Light Dependent Resistors) or thermistors (tempe ...
