The Axial SCX10 Dingo chassis with the master light controller unit in the open receiver box. It *just* fits on top of the HK3000 receiver from HobbyKing.
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 Tara O'Con, presenting at Maker Faire NYC. Thanks to Chris Cummings for the photo!

As the electronics hobbyist one of knowledge that we have to be familiar with is how to make our own printed circuit board (PCB). Making our own simple single side PCB actually is not require a sophisticated technique and technology as you might think, instead most of the required materials is already available at your home.

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 is a view of the electronics inside the model R/C tank I am designing on a gearbox + Tracks & wheels from Tamiya. The radio is Hitec and two receiver servo outputs feed my microcontroller-based Pulse Position Modulation output into Pulse Width Modulated power output to the two motors.

This is all you need to get a microcontroller running. In fact, even the clock crystal and reset button are optional.
Building a simple and easy microcontroller based robot is always a fascinating topic to be discussed, especially for the robotics newbie enthusiast. On this tutorial I will show you how to build your own microcontroller based robot which known as a photovore or you could call it as the light chaser robot using the simplest possible circuit for the microcontroller based robot brain, locomotion motor and the sensor.

This is an MSP430G2001 microcontroller from Texas Instruments, part of their new value line. The die badge reads MSp430F2011D.
Would be interesting if we could make our microcontroller to sing for us not just beeping or blinking; this project is all about using the powerful AVR ATmega168 16-bit PWM feature to produce accurate musical notes such as playing the child’s favorite Twinkle-Twinkle Little Star song or we could say beeping with style.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced its first instrumentation amplifier, the MCP6N11. The new instrumentation amp features Microchip’s unique mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means to control offset drift, which results in higher accuracy across time and temperature. The MCP6N11’s low-power CMOS process technology enables low power, while providing a gain bandwidth product of 500 kHz, and it features a hardware shutdown pin for even more power savings. The device’s low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.

This is a backup board (the proto-board versions come in sets of three anyway) showing the components. The large IC is the PIC16F887, an 8 bit microcontroller with 38 IOs (including 10 A2Ds if desired - all output pins are programmable on the fly). The small IC to the left is the Dallas Semi conductor Real Time Clock chip, which is interfaced to the PIC with a I2C serial bus. The large disk to the left is the battery used to keep the RTC alive when the unit is not powered. The white header next to the battery is for the hand controller and autoguider (ST4) interface. Above the PIC is the In-Circuit Serial programming interface. To the right of the PIC are the two daughter boards that drive the steppers in any of the various modes (from full to 32 microsteps) Under the daughter boards there are jumpers which can be used to configure the main board to use either these (based on a TI chip) or similar boards (full to 16 microsteps) based on the Alegreo driver chips. The crystal for the processor is 20mhz, giving an instruction cycle time of 2e-7 seconds. When both axes are running at the full planned rate (960X sidereal) less than 50% of the CPU time will be used. The board will also support one of the PIC18F chips with a 40mhz clock with more performance and memory. All through-hole technology for ease of repair and assembly.
The new PIC32 Ethernet Starter Kit (part # DM320004, $72) was designed to enable easy Ethernet-based development with Microchip's three new PIC32MX5/6/7 families of 32-bit microcontrollers. For more info visit www.microchip.com/PIC32.
Russ connected an MCP4822 dual 12-bit digital-to-analog converter (DAC) to the fine Tektronix 2213A oscilloscope. A program (sketch) on the Arduino microcontroller drives the DAC and generates the image by steering the scope's CRT beam along the lines in the drawing (vector-scan). en.wikipedia.org/wiki/Vector_monitor

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.
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.
