Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The well-known 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think about the robot should be. Although the robot that we are going to build here is still far away from the technologies shown on those movies but at least it will give you an introductory to the robotics world. for more information please visit www.ermicro.com/blog/?p=983
This is a full size mockup I put together to test some concepts for my LED array project. There are 16 RGB LEDs spaced about 2.25 inches apart, with scored and folded cardboard light separators. The final array will have 24 of these rows, with the same minimal spacing between all pixels (no 3/4 inch border). The LEDs are PWM controlled to any of 4096 brightness levels per color.
Microchip Technology's PIC18F87K90 8-bit microcontrollers (MCUs) feature nanoWatt XLP Technology, 1.8 - 5.5V Operation and CTMU Module for Capacitive Touch Sensing. The MCUs can also drive LCDs up to 192 Pixels.
This is the CC2530, an 8051 microcontroller with integrated 2.4GHz radio from Texas Instruments. As usual, this had to be rather cruelly compressed to fit on Flickr, even with a Pro account. Email me if you'd find the original to be handy.

This is an laser cut enclosure for mobile arduino prototyping. I will start selling this soon. A bit more testing is needed.
Check:
My Arduino, on a bamboo base-plate, connected to an Allegro A3982 stepper motor driver chip. The chip is surface-mounted on the other side of the PCB.
The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, I decided to use the PIC12F683 microcontroller to generate simple and yet fascinating laser light show from a cheap keychain laser pointer.

A good power supply is an essential subject to the microcontroller's base project; it's like a heart that gives a life to our microcontroller. Sometimes we take it for granted the important of having an adequate power supply to our microcontroller project and this can lead to the unexpected result or behavior from the circuit.

Just the SMT transistors to add on the back. Hand soldering the TQFP AVR microcontroller was interesting.

Arduino UNO was one of the first ever circuit portraits, way back in 2013. This is a new edition with an extra layer and a bit more finesse.

This is the replacement hardware. The core is a PIC18f4550 controlling everything with a 20Mhz oscillator to supply the PLL for the 48Mhz required to run USB should i ever get round to implementing that. The CPU runs at 8Mhz from the internal osc. There is a MAX232 to drive the serial port and some transistors to switch relays for the spindle and that is about it. the 9 pin plug floating there is just to allow me to debug the board when it is not in the machine. The screw terminals will be for the motor and the spindle encoder but the encoder is not implemented in code yet so I haven't connected it. Some fly back diodes for the relays, caps for the MAX232 charge pumps, transistor base resistors, LEDs for debugging, ICSP plug and some wire make up what is left. Not really all that much there. I will probably add another transistor and 2 resistors and a cap to this to amplify the PWM signal since the PIC gives out 5Vpk-pk and the PWM in the control box needs 0-10V in. (I know its a bit silly generating an analogue voltage from a PWM output only to use it to control another PWM drive but this way it is a direct board swap.)

Microchip Technology's 8-bit, low-cost, Enhanced Mid-range Core PIC16F1516/7/8/9 and PIC16F1526/7 (PIC16F15XX) microcontrollers (MCUs) feature eXtreme Low Power (XLP) technology for sleep currents down to 20 nA, which lowers overall power consumption and extends battery life. An on-chip 10-bit Analog-to-Digital Converter (ADC) with up to 30 channels enables mTouchâ„¢ capacitive touch-sensing keys and sliders, and high-resolution touch-screen designs. Up to two each of EUSART, I2Câ„¢, and SPI ports enable communication with on-board peripherals. They are ideal for cost-sensitive applications in the consumer (e.g. DVD players, cell phones, MP3 players); automotive (e.g. dashboards, gauges, on-board sensors), home appliance (e.g. washing machines, refrigerators, TV remote controls), and other markets.
Microchip Technology's Fanie Duvenhage (Director of Marketing, Applications & Architecture) accepts VDC Research’s annual "Embeddy" award for best in show, hardware category at the Embedded Systems Conference (ESC) in Boston on Sept. 28, 2011. Microchip won the award for the Sept. 26 announcement of its new 8-bit PIC10F(LF)32X and PIC1XF(LF)150X microcontrollers, which feature integrated configurable logic in 6- to 20-pin packages—enabling functionality that was not possible before with low pincount MCUs.
Microchip's PIC12LF1840T48A is the first in a family of single-chip devices that integrate an eXtreme Low Power (XLP), 8-bit PIC® microcontroller with a sub-GHz RF transmitter. The PIC12LF1840T48A’s combination of features in a single, 14-pin TSSOP package makes it ideal for space-, power- and cost-constrained applications, such as remote keyless entry fobs for automobiles, garage doors and home security systems, as well as a broad range of other home and building automation systems. Additionally, the device is optimized to run Microchip’s royalty-free KEELOQ® advanced code-hopping technology, a proven security technology used worldwide by leading manufacturers.

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

Sorry for the techno nerdy picture. The excuse is I purchased some extension rings and wanted to try it on something. This is an ESP32 (32 bit processor) board. We use these devices in some of our projects. The board measures 50mm by 28mm. The image is a focus stack of 10 images done in camera.

The 5V outputs from the Arduino are wired to a CD4050 hex buffer chip, which acts as a level shifter. The LCD (from a Nokia 1202 mobile phone) is entirely 3.3V.
Microchip Technology's MCP6401/2/4 Operational Amplifiers (Op Amps) provide lower power consumption in small packages. Featuring quiescent current of just 45 microamperes at 1 MHz, the MCP6401/2/4 devices are an excellent complement to Microchip’s eXtreme Low Power PIC® microcontrollers (MCUs), helping to extend battery life in a variety of consumer (e.g. music players, appliances and gaming consoles); industrial (e.g. barcode scanners and gas meters); automotive (e.g. signal conditioning for proximity and tire-pressure-measurement sensors); and medical applications (e.g. glucometers and portable patient-monitoring devices), among others.
