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.
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.

My laptop, Arduino, H-bridge driver, stepper motor and belt-driven disk. It's a rig that I'm working on for a couple of future projects.
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.
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.

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

The CX-85 keypad (ca. 1982) was designed for the Atari 800 computer. It turns out to be extremely simple to interface with modern elecronics.
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.

This is an laser cut enclosure for mobile arduino prototyping. I will start selling this soon. A bit more testing is needed.

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.

The Ethernet PICtail™ Plus Daughter Board provides a cost-effective method of evaluating and developing Ethernet control applications. The board is designed for flexibility and can be plugged into Microchip’s Explorer 16 (DM240001) development boards. The development board is populated with Microchip’s 28-Pin ENC28J60 Ethernet controller which interfaces to the RJ-45 female connector. When used in conjunction with the Microchip TCP/IP stack (free download below) the Ethernet PICtail Plus daughter board allows a developer to connect any Microchip 16-bit product to the Ethernet.
Features
IEEE 802.3 Compliant
10BASE-T Ethernet
RJ-45 Female Ethernet Connector
Plug in compatible with the Explorer 16 Development Board (DM240001)
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.

A pwb course exercise. I had to lay out a circuit in Orcad, I wanted to try a certain clock generator and I've been thinking of putting some of the 8515's on a board. So I threw something together. Two sided board, plated vias, milled with some machine. Kind of tricky to solder. Larger pads and holes would have been welcome in hindsight.
Picaxe microcontroller project: thermostat. Bottom view with SOIC Picaxe 18X, programming jack to the left of it, and various 0612 size resistors, two for the programming circuit, one a pull up resistor for the temp sensor, one to the reset pin on the 18X, another current limiting for the LED.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced its expanded MiWi™ Development Environment (DE), which is a complete ecosystem for designing star and mesh wireless networking products. The MiWi DE is comprised of Microchip’s free, proprietary MiWi P2P, MiWi and MiWi PRO star and mesh networking protocol stacks; the 8-bit Wireless Development Kit (WDK) and ZENA™ Wireless Adapters (2.4 GHz, 868 MHz and 915 MHz); and the multi-purpose Wireless Development Studio (WDS) with cross-platform support for the Linux, Mac OS® and Windows® operating systems.
A few more steps towards a usable system!
* Programmed FPGA to blink LEDs (the most important thing in any project)
* Wrote initial firmware for microcontroller, and it's now able to read/write the onboard flash chip, as well as program the FPGA all by itself :)
Next: some more work on the FPGA and probably initial motor control pretty soon. Well, that or smoke.
Enables serial communication with arduino or other microcontroller for control of external devices (like servos used as projector shutters) or sensor input to control elements in VPT
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.
Microchip Technology's MCP4706/16/26 non-volatile Digital-to Analog Converters feature buffered 8-,10- and 12-bit voltage output options and integrated EEPROM, and are offered in a miniature 2 mm x 2 mm DFN package, as well as a 6-pin SOT-23 package.
