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.
Just got myself a new Arduino UNO. It took me just a few minutes to install the software and load an example program to test the board. Because its based on the C language and im familiar with that its very easy to write code for it. Look forward to using it in a project soon...
Microchip announced a new family of PIC32MX1/2 microcontrollers (MCUs) in 256/64 KB Flash/Ram configurations.

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

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.
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.
Two Nikon SB800 flash units controlled by an Arduino microcontroller. Triggered by a piezo sensor on the air gun.

Electronics = [Brohogan's] DIY Geiger Counter board.
Box: Velleman G1189BC, this is a roomy enclosure with a 9V/2xAA battery space. Currently using 9V NiMH, planning to upgrade to 2xAA + 5V boost converter (in the mail from China).
Buttons: On/Off, sound On/Off, a menu and up/down buttons to change items in menu.
Software is crude, main features are exponential smoothing for CPM and background measurement in menu to compare current measurement with.
The counter has a 1/8"/6.35mm TRS socket for removable probes, currently an SBT11A.
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.
This is 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 the microcontroller-based Pulse Position Modulation output to Pulse Width Modulation converter.

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.

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.

This is the link to the schematic of the model R/C tank I am designing on a gearbox + Tracks & wheels from Tamiya. Full details with schematic at www.5volt.eu
Most of the holes are drilled to 0.8mm, but some are 1.0mm. In particular, the programming header, the I/O port connectors and the reset switch need the larger hole sizes.
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. The DACs are ideal for applications in the consumer and industrial markets, such as wireless microphones and mp3-player accessories; and applications such as motor control, flow measurement, temperature control and light control.
To give you an idea of the scale of these little blighters, the texture you see them "standing" on is not anything fancy, it's just standard copier paper. I was surprised how much texture you could see on a close up view like this
