Automatic Raspberry Pi board revision detection: model A, B1 and B2 #piday #raspberrypi @Raspberry_Pi Posted: 08 Feb 2013 02:00 AM PST Now that there are a range of Pi (and Frank declares "Now that I know how many there are, it kind of makes me want to collect them all") resources like his chart of revision codes are handy to plan for differences from model to model for your software and hardware solutions. From Raspberry Alpha Omega: When the raspberry Pi model A was announced a few days ago, I ordered one straight away. With three different models of raspberry Pi now available (or four, if you count the red Chinese variant), working out the capabilities of the board is becoming increasingly important. It's vital for anyone involved in making hardware or software for other people to use, and it's even pretty important for personal projects – you never know when you might want to use your hardware and software with a different board… Read more.

Re: Speed control of a 24V with Arduino Posted: 08 Feb 2013 01:45 AM PST you say you are not an electronics expert; but you are going to remain there if you do not experiment . its acuallty pretty easy to understand . all you need to know is the working of a transistor, and a dpdt relay.

Controlling a servo motor with the Raspberry Pi #piday #raspberrypi @Raspberry_Pi Posted: 08 Feb 2013 01:00 AM PST Check out this great project from the most recent meeting of the Pumping Station: One workshop "NERP" (Not Exclusively Raspberry Pi), shared by Drew Fustini: During the last embedded systems meetup at my hackerspace in Chicago, Pumping Station: One, we did hands-on activity where we went through a couple of Adafruit's wonderful tutorials.  First, we learned how to read a photoresistor without an ADC using Adafruit's Basic Resistor Sensor Reading on Raspberry Pi.  Next, we hooked up typical 5V hobby servo motor to the Pi per Adafruit's Raspberry Pi Lesson 8. Using a Servo Motor (written by element14 member simon.monk!): The red board atop the Pi is the Pi Crust breakout board by Pumping Station: One member, Joe Walnes.  It's a compact and low-profile way to interface with the GPIO header.  Alternatively, the Pi Cobbler breakout board is shown in the Adafruit tutorial.  Note: the current Raspbian image doesn't have the Adafruit's PWM kernel module, so it is necessary to run Adafruit's Occidentalis image for the servo tutorial to work.   Fellow hackerspace member, Jay Hopkins, had the great idea to wheel over the oscilloscope to demonstrate how the pulse width of the signal on the Pi's PWM pin corresponds to the degree to which the servo rotates. (The spining red board on top of the servo motor is just a spare Pi Crust.  It's only function was to make it easier to see the servo was moving.)   The Adafruit servo tutorial has a great explanation of how the position of a servo motor is controlled: The position of the servo motor is set by the length of a pulse. The servo expects to receive a pulse roughly every 20 milliseconds. If that pulse is high for 1 millisecond, then the servo angle will be zero, if it is 1.5 milliseconds, then it will be at its centre position and if it is 2 milliseconds it will be at 180 degrees. Read more. Featured Adafruit Learning System Tutorials Adafruit's Raspberry Pi Lesson 8. Using a Servo Motor: This lesson describes how to control a single servo motor using Python. Servo motors are controlled by pulses of varying lengths. This requires fairly accurate timing. The Raspberry Pi has one pin that generates pulses in hardware, without having to rely on the operating system. Occidentalis includes an interface to make use of this pin for controlling a servo motor. (read more)

Re: Incubator project Posted: 08 Feb 2013 12:47 AM PST you need to explain better what you already did or post the code you have so far, otherwise probably nobody will help you... i guess good luck

Re: Disco LED Dancefloor + more Posted: 08 Feb 2013 12:44 AM PST I have no idea if 120mm is a hard limit; if so, the design I posted is a bit oversized at 124mm without accounting for an additional black border around it. So with the WS2811 pixels, you would either need to go 6x6 and fill in the edges diagonally as ...

Raspberry Pi Time Clock: Gaugette Time Clock #piday #raspberrypi @Raspberry_Pi Posted: 08 Feb 2013 12:00 AM PST Here's a great project using a bunch of Adafruit gear, as well as Occidentalis v0.2 and the Adafruit Fritzing library to solve a common freelancers challenge: it provides a visual reminder as to when you are recording your time spent on one project or another. This rather nice implementation might fit as happily on a lawyer's desk as a coder's or engineer's! From Guy Carpenter. This build combines a Raspberry Pi with a rotary-encoder, an RGB LED and an OLED character display to create a time clock that logs my time on tasks directly to a Google Docs spreadsheet. Motivation Whenever I have to record time against projects, I find it really hard to diligently keep my time records up to date. Maybe with a purpose-built time clock I will keep better records? Maybe. Overview The off-the-shelf components: Raspberry Pi model B Rev 1 – Adafruit has the Rev 2 board. 128×32 SPI OLED display – Adafruit Rotary Encoder – Adafruit 5mm RGB LED – Sparkfun Occidentalis 0.2 – Adafruit 6" Female/Female jumper wires – Adafruit 3" Female/Female jumpers wires – Little Bird Electronics or Adafruit I used a common cathode LED from Sparkfun. You could use Adafruit's common anode equivalent with minor code changes. The theory of operation is pretty simple: at start-up, it pulls a list of jobs from a Google Docs spreadsheet, rotating the knob scrolls through the list of jobs, clicking the knob logs a start time or end time in the spreadsheet…. Read more. Featured Adafruit Products Raspberry Pi Model B 512MB RAM: The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It's a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 128 or 256 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems. This is the Raspberry Pi Model B 512MB RAM model with two USB ports and a 10/100 Ethernet controller. (read more) Monochrome 128×32 SPI OLED graphic display: These displays are small, only about 1″ diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128×32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness! (read more) Rotary Encoder + Extras: This rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also include a nice soft-touch knob with an arrow in it, fits perfectly and looks great. This encoder also has a push-button built into it so you can press onto the knob to close a separate switch. One side has a 3 pin connector (ground and two coding pins) and the other side has two pins for a normally-open switch. (read more) Occidentalis v0.2: This is our second distro, Occidentalis v0.2. Rubus occidentalis is the black raspberry. It is derived from Raspbian Wheezy August 16. We have made a few key changes to make it more hardware-hacker friendly! (read more) Premium Female/Female Jumper Wires – 40 x 6″: Handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are a little over 6″ (150mm) long and come in a 'strip' of 40 (4 pieces of each of ten colors). They have 0.1″ sockets on either end and fit cleanly next to each other on standard-pitch 0.1″ (2.54mm) header. We recentlty updated these so they are in a 'ribbon strip' instead of individual wires. You can always pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses.
