Receiver showing signs of life in its new "Arduino-free" environment.
Note that I'm using a different LCD panel as I was experiencing some difficulties with the original one.
No evidence of any power rail decoupling there - however I seem to have got away with it.
The yellow wire disappearing off to the top left is the data line from the out-of-shot MSF receiver.
The LED is "repeating" the data signal as a confidence check that valid data is (probably) being received even before the software has made sense of it.
The LED being ON corresponds to the RF carrier from MSF being OFF.
The final project will hopefully be slightly better engineered!
This is a JeeNode SMD from that friendly Dutchman at JeeLabs
It was partially as a challenge, the reduced size was a bit of an incentive, but at €10.50 it was impossible to resist!
So just to prove you can solder SMD devices with nothing more than an 18Watt Antex soldering iron (with a 0.5m tip), a bit of plumbers flux (a small paint brush to apply it), some flux remover spray to clean it up later and a bit of desoldering wick for those bridged pin moments...
To give you an idea of scale, the pins on the far right, and all those little gold plated through holes, are 0.1" apart. 2.54mm.
I wasn't that confident of success, so I actually ordered two of these little kits, but the first one worked, so I've now got a second one to build if I'm feeling brave...
Shot with an SB800 off camera commander remote to left, and a bit of white card to the right to bounce some back. I think I should have deployed a second flash, but you get the idea :-)
Both pieces should wrap around to the other side. The lower left leg of the microcontroller will connect to the negative (-) terminal of the battery; the upper right leg to the positive (+) terminal.
The veroboard layout and cut-plans for my variant of the HIDKeys firmware-based USB keypad controller. (See decarchive.org/~prd/2010/02/attiny2313-based-usb-keypad-c... for more details.)
Wiring of the LEDs in the bumpers. A short half of a servo extension lead makes the bumpers detachable for cleaning.

This six-member family of 32-bit PIC32MX5/6/7 microcontrollers provides the same integrated Ethernet, CAN, USB and serial connectivity peripherals with new, more cost-effective memory options. Additionally, design enhancements have been made that provide lower power consumption of 0.5 mA/MHz active current, higher Flash memory endurance of 20k read/write cycles and better EEPROM emulation capability. And, by maintaining common pin outs, the PIC32 portfolio provides designers with a seamless migration path to achieve the correct balance of memory and cost for their high-performance applications.

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.

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

Die shot of an 8-bit microcomputer (basically a microcontroller) from a sewing machine. Most of the program data was stored on a separate chip. The long two blocks at the right are rom too, but there’s only 8kb worth on the die.

The DMC 60 is a powerful and compact motor drive/amplifier designed for robotics, electric vehicles, or any application where easy bidirectional control of DC brushed motors is needed. The DMC 60 is controlled using a standard hobby servo PWM signal - the same output from RC controllers and also easily generated by microcontrollers or FPGA boards. The DMC 60 is approved for use in the FIRST Robotics Competition (FRC) and is designed to be electrically and mechanically compatible with the Victor SP motor controller.

Having found that the ATtiny85 didn't have enough memory to hold my brainwave visualisations code, I put together a little Shrimp circuit to hook up the LED matrix and Bluetooth dongle. Attention data levels is visualised as red LEDs and meditation data levels as green LEDs.
The stepper motor on the barn door tacker is controlled by the Arduino microcontroller, right. The Arduino interfaces with the stepper motor through the A4988 Stepper Motor Carrier Driver on the breadboard, left. The microswitch is the 'home' sensor that is mounted on the hinge.
On power-on and reset, the control system opens and closes the hinge while monitoring the state of the home-sensing switch to locate the home position, when the actuator is extended at nominal zero millimeters. Thereafter, the controller extends the actuator to open the hinge to match the earth's rotation. (The resistor on the Arduino isn't part of the circuit. I'm using its lead to access the Arduino's Pin 8 ditital output.)
Missing from this circuit are:
- The kill switch that will shut off the motor if the software
looses its mind.
- The circuitry to microstep. As shown, the stepper motor
resolution is 1/200th of a turn per step instead of the
intended 1/3200th of a turn per microstep.
- The 12 Volt battery pack that powers the control system and the stepper motor.
- The DC-DC converter that steps down 12V power to 5V
required by the control system.
I might expand the Arduino's functionality to implement an anti-dew system, too. I have a 12V supply that can deliver plenty of current. Perhaps I'll implement an adjustable PWM output on the Arduino to drive a transitor that will control a heater for the camera lens. It doesn't take much energy to drive off the dew.
Freeing the microcontroller from its Arduino shackles.
One could simply lift the micro from the Arduino board and build the key additional components required around it.
However I wanted to use a "fresh" micro, but this required the Arduino bootloader to be burned onto it in order to allow it to be programmed from the Arduino ...
It's all a bit of a faff, but that is kind of "the point" of doing it!
This fabric-based microcontroller project has been taking up more and more of my life. Every corner turned, every goal reached, opens up a thousand new possibilities and a thousand new tests to make.
Here I am with presenting at Maker Faire NYC. Thanks to Chris Cummings for the photo!
Sanguino is an open source Arduino-compatible microcontroller board that is based on the Arduino, and inspired by the Boarduino form-factor. It uses the atmega644P chip which has 4x the memory, ram and 12 more GPIO pins than the Arduino's atmega168.

Jay, my partner in crime, is learning how to work with the basic stamp. This is his latest project, multiple blinking LEDs.

A fun and easy way to get started with programming and hardware interaction. The Inventor Kits are used for classes and special programs in the Lee Innovation Lab.
My first microcontroller (Parallax BASIC Stamp) project is successful - the red and green LEDs are blinking back and forth (alternating, although you cant tell that in this photo). I've turned off my desk lamp so you can see them more clearly.
