When found by the artist, this small oyster shell had a perfectly round hole drilled into it, perhaps by a predator. The hole was a perfect fit for a light-emitting diode.
It dimly blinks the “Arecibo message,” a transmission sent towards star cluster Messier 13 from the then-new Arecibo radio telescope in 1974. Though it was considered a “message to aliens,” the Arecibo transmission was brief, less than three minutes in duration, and was sent only once. It was a demonstration of the telescope creators’ technical prowess more than an earnest attempt to advertise humanity.

The chipKIT PGM is designed to work with the MPLAB® and MPLAB X development environments available from Microchip. This allows the chipKIT boards, for example, to be used as a more traditional microcontroller development platform using the professional tools available from Microchip. While the PICkit™3 programmer can generate programming voltages needed to program all Microchip PIC devices, the chipKIT PGM can only program devices that are programmable with 3.3V programming voltage. Further, the PICkit3 can source a small amount of current to provide power to some boards being programmed. The chipKIT PGM does not provide power to the board being programmed.

My company, AVIX-RT, develops and markets an RTOS for Microchip PIC24/dsPIC microcontrollers. Since the main focus is on software, for hardware I am always looking for easy solutions where I do not have to spend a lot of time reaching my goals. I found such a solution with Schmartboard. Schmartboard enables me not only to create a converter, making it easier to work with SMD devices. Schmartboards offer much more than this. These boards allow me to put complete circuits on a single board reducing footprint and ‘Time to Prototype’, this all with minimal effort. I really love these boards since they allow me to focus on my main goals. More information can be found at www.avix-rt.com
David presents an interfacing Arduino and Adobe Flash. Dorkbot crowd makes up a quick game called "Busy Proctologist" using some craft items, a pressure sensor, and the goatse image.
The crowd concluded after finding a latex glove, a styrofoam ring, some bubblewrap, and some red and brown felt, and a pressure sensor that the game would be called "Busy Proctologist."
Gameplay involves "examining" as many patients in the day as possible (measure by a 1 minute timer in Flash) without causing undue discomfort during the rectal exam (exceeding a moderate pressure range measured by the sensor and arduino.)
With a little twist.
Twiddle the knob to change the pretty light display.
(Believe me, I found that tricky enough to implement at first!)

This Arduino shield by Bulgarian company Olimex is a rather strange beast which incorporates an onboard PIC microcontroller to read serial data in and display it on the 16x2 LCD using a custom library (amongst other things).
I'd mistakenly read the manufacturer's name as Olimerx, not Olimex,

Talks and performances by people doing strange things with electricity
Fri 23 March 2012, 6.30-10pm with interval at the Showroom Cinema, Sheffield.
Dorkbot is a meeting of people interested in electric/electronic art in the broadest sense; robotics, kinetic art, microcontrollers, interactive art, algorithmic music, net.art... The only real conditions are that it is a bit strange and involves electricity in some way. It is really defined by whoever turns up, be it engineers who want to be artists, artists who want to be engineers, or the otherwise confused.
This MEGADORK event features a cabaret of talks and performances from among the UK's dorkiest, to entertain and amaze:
Paul Granjon - A strange performance from the world renowned self-styled robot artist.
Patrick Tresset - Talks about his drawing robot Paul (on show as part of the Alan Turing: Intuition and Ingenuity exhibition).
Daniel Jones and James Bulley - talking about generating live music from patterns of weather.
www.variable4.org.uk/about/intro
Sarah and Jenny Angliss - playing robot music from past futures.
spacedog.biz
Sergi Jorda - talks about the Reactable tangible tabletop music playground (which you'll be able to try out at the Central Library Saturday 24 March)
Dan Stowell - Demonstrates his use of the Risset illusion in techno music.
Silicone Bake - Live coded pop songs about love, death and counterfeit watches, where all lyrics are taken from spam emails.
Megadork is curated by Alex McLean.
Dorkbot started in New York, spread to London, and now dozens of cities around the world, including several active UK chapters; Sheffield, Bristol, Anglia, Newcastle, Cardiff and Alba (Scotland). Find out more at: www.dorkbot.org

Microchip announced a new addition to its PIC12/16LF155X 8-bit microcontroller (MCU) family with the PIC16LF1554 and PIC16LF1559 (PIC16LF1554/9) devices. The PIC16LF1554/9 includes two independent 10-bit 100K samples per second Analog-to-Digital Converters (ADC) with hardware Capacitive Voltage Divider (CVD) support for capacitive-touch sensing. This unique ADC configuration enables more efficient sensor acquisition and assists with advanced touch-sensing techniques for extremely noisy environments, low-power applications, matrix keypads and water-resistant designs.

Game controller with 2 microcontrollers inside (ATTINY85), both generating algorithmic music.
For each microcontroller, the 2-axis analog stick controls two variables of the currently selected algorithm, the switch of the analog stick cycles the algorithms and an additional switch is used to mute/unmute the sound.
Note: Nothing fancy here, this a just a demo with only 4 algorithms and the same program on both microcontrollers.
These days we are living and surrounding by many tiny computers called embedded products.

This was a later test to see if I could mill a tube, kinda like a little bullet casing. The answer is a resounding "kinda." It still suffers from the grain problem mentioned in the previous pic, wherein bars formed with crappy aluminum don't mill evenly as spun around beneath the end mill. Certain edges mill cleanly, while others seem to flake away, leaving lost, unsharp edges.
In the background you can see the DIN cable plug into a simple board I made that connects to a BASIC Stamp BS2p40, which is on the stamp dev board (with the green power LED). All it does it kick out a steady stream of rotation commands to slowly rotate the rotary table. In this pic, the table sits on the angle plate, which is just there to raise it up enough to give the rotary table's CNC motor (foreground right) clearance over the Y axis handwheel (out of frame bottom). On the rotary table is a 4-jaw independent chuck, which is holding the 0.25"x0.75" stock vertically for the milling. Using the rotary table, I cleared away the space around a little bar shaped piece, and then began milling the tube into the center of it. Obviously, I can't get much depth with that tiny 1/8" end mill, and moreover, this operation is far more suited to both a lathe (almost next on my wishlist), and better grades of aluminum, or other metals entirely.
Again, just another test. Note also the white copy paper and black electrical tape way-guards. I don't like getting shavings around the exposed Y-axis threaded rod, and I haven't made a fancier system yet. This works quite well for now.
chipKIT Pro MX4 : Embedded Systems Trainer Board
The chipKIT™ Pro MX4 is a microcontroller development board based on the Microchip® PIC32MX460F512L, a member of the 32-bit PIC32 microcontroller family. It is compatible with Digilent's line of Pmods, and is suitable for use with the Microchip MPLAB® IDE tools. The chipKIT Pro MX4 is also compatible for use with the chipKIT MPIDE development environment.
The chipKIT Pro MX4 provides 74 I/O pins that support a number of peripheral functions, such as USB controller, UART, SPI, and I2C ports as well as five pulse-width modulated outputs and five external interrupt inputs. Fifteen of the I/O pins can be used as analog inputs in addition to their use as digital inputs and outputs.

PmodWiFi: WiFi Interface 802.11g
The PmodWiFi provides Wi-Fi access through the Microchip® MRF24WG0MA Wi-Fi™ radio transceiver module. Users can communicate with the IEEE 802.11g compliant chip through SPI and achieve data rates up to 54 Mbps.
The stepper motor is being powered by a simple circuit from a BASIC Stamp BS2p40 microcontroller. You can see the black plastic handle on the red anodized aluminum hand wheel spinning. The motor has 200 1.8º steps (common for stepper motors). The rotary table takes 72 revolutions of the motor shaft to spin 360º, and that's 200x72, or 14,400 discrete locations. That works out to 0.025º, or 1/40 of 1º per step. Not too shabby! These unipolar steppers can be driven in half-steps, yielding 28,800 discrete locations at 1/80 of 1º intervals, but I haven't tried that yet.
Given the 4ms delay per step I set into the motors - any faster and there really isn't enough torque generated per step to fight the load of the rotary table's gearing - the 14,400 steps needed for a full spin works out to 57.6 seconds for a full revolution of the rotary table, which sounds about right. It spun slowly, which is a bit necessary to get smooth cuts on such light duty equipment.

Dit een gestripte versie van mijn DIY ArnoSync camera trigger. Deze versie is eveneens opgebouwd rond een PIC 12F675 microcontroller. Het is een versie met een lichtsterkere lens met een brandpunt afstand van 100 mm. Het apparaatje kan hierdoor een object in focus detecteren tot op 1 meter afstand van de camera.
Het is de bedoeling deze versie te gebruiken voor vogelfotografie. De gebruikte lasermodule is een IR (Infra Rood) versie welke ik nog beschikbaar had.
Alle onderdelen passen nog net op een mini breadboardje.
Het geheel is opgebouwd met een minimum aan onderdelen.
De aansluiting naar de Sony A6000 camera remote shutter input gebeurt nu via een robustere 3.5 mm chassis stereoplug. Voor de aansluiting naar de Sony A6000 synchro kabel is dus een extra 3.5mm naar 2.5 mm stereoadapter plugje nodig.
De voeding van het geheel gebeurt door een externe 5 Volt Mini Powerbank van 2600 mAh met schakelaar. Deze combinatie heeft een autonomie van ca. 100 uren. Door het gebruik van de on-off schakelaar enkel wanneer een detectie verwacht wordt kan er meerdere weken op een volgeladen Powerbank gewerkt worden.
-------------------------------------------
This is a striped-down version of my classic DIY ArnoSync camera trigger device.
This version is still build around a PIC 12F675 device. The mini system uses a better lens (100 mm focus) before the SFH309 phototransistor. The working distance to the object is now about 3 feet.
The used Lasermodule is an IR (Infra Red) type which I found in my junk-box.
All the electronics are mounted on a mini prototype breadboard. The connection to the Sony A6000 camera is done via a 3.5 mm stereo chassis plug. A 3.5 mm to 2.5 mm adapter is needed to mate the Sony A6000 external shutter release cable.
The used power supply is a small 2600 mAh Powerbank of 5 Volt with an ON/OFF push button switch. This allows power for more as 100 hours in continuous operation or several weeks when only switched on when an object is expected in the detection zone.
