Detail of a single chip calculator IC from 1971, arguably one of the first microprocessors or microcontrollers having a RISC instruction set in ROM and with RAM. This complex IC was drawn out by hand on Mylar film and photo-reduced 400X. Calculators became the largest market for ICs by the mid 1970s.

Homemade Sprinkler or Universal Timer

Microchip announced from Electronica in Germany an expansion of its 8-bit PIC® microcontroller (MCU) portfolio, with the peripheral-rich, low-pin count PIC16(L)F161X family. These new MCUs introduce and expand the offering of Microchip’s Core Independent Peripherals (CIP), which were designed to reduce interrupt latency, lower-power consumption and increase system efficiency, and safety, while minimizing design time and effort. These peripherals are designed to reduce system complexity by eliminating the need for additional code and external components. Hardware-based peripherals offload timing-critical and core-intensive functions from the CPU, allowing it to focus on other critical tasks within the system.

Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced its partnership with Silicon Integrated Systems Corp. (SiS) to provide customers with complete projected-capacitive touch (PCAP) and 3D-gesture interface modules, which will lead to faster development and lower costs. The modules will make it easier to design multi-touch and 3D gesture displays with Microchip’s award-winning GestIC® technology, which offers a hand tracking range of up to 20 centimeters (cm) from the display surface. Hand gestures are universal, hygienic and easy to learn. In addition, they enhance safety by reducing the need for precise hand-eye coordination.

To learn more about Microchip’s GestIC technology products, visit www.microchip.com/pagehandler/en_us/technology/gestic. Additionally, SiS modules with Microchip’s GestIC technology will be demonstrated at Microchip’s Consumer Electronics Show (CES) Booth MP25656 in Las Vegas, from January 6-9, 2016.

Fishing line power transmission.

 

The first time I saw the Timescapes teasers I knew I would have to build a camera slider and explore the timelapse world for myself.

After a lot of research on this forum and a lot of late nights I have finally tested my motorised camera slider.

Lego gearset (don't laugh it works a treat) fishing line power transmission, aluminium door frame extrusion, Arduino micro controller and a 12v stepper motor. Note the termination of the fishing line with stainless steel thimbles and cotton covered hair bands, this takes up any harsh speed changes or direction changes.

All my demo timelapses have worked just fine.

The attached photos might explain the build better.

mixed up with Microcontrollers

Most of microcontrollers work within 5 volt environment and the I/O port can only handle current up to 20mA; therefore if we want to attach the microcontrollers I/O port to different voltage level circuit or to drive devices with more than 20mA; we need to use the interface circuit. One of the popular method is to use the Bipolar Junction Transistor (BJT) or we just called it transistor in this tutorial. For more information please visit www.ermicro.com/blog/?p=423

Microchip announced from EE Live! and the Embedded Systems Conference in San Jose the PIC16(L)F170X and PIC16(L)F171X family of 8-bit microcontrollers (MCUs), which combine a rich set of intelligent analog and core independent peripherals, along with cost-effective pricing and eXtreme Low Power (XLP) technology. Available in 14-, 20-, 28-, and 40/44-pin packages, the 11-member PIC16F170X/171X family of MCUs integrates two Op Amps to drive analog control loops, sensor amplification and basic signal conditioning, while reducing system cost and board space. These new devices also offer built-in Zero Cross Detect (ZCD) to simplify TRIAC control and minimize the EMI caused by switching transients. Additionally, these are the first PIC16 MCUs with Peripheral Pin Select, a pin-mapping feature that gives designers the flexibility to designate the pinout of many peripheral functions. The PIC16F170X/171X are general-purpose MCUs that are ideal for a broad range of applications, such as consumer (home appliances, power tools, electric razors), portable medical (blood-pressure meters, blood-glucose meters, pedometers), LED lighting, battery charging, power supplies and motor control.

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.

Microchip announced the expansion of its Low Power PIC® microcontroller (MCU) portfolio. Features of the new PIC24F “GB6” family include up to 1 MB of Flash memory with Error Correction Code (ECC) and 32 KB of RAM, making it the first 16-bit MCU in Microchip’s portfolio to offer such a large memory size. Also featuring dual-partition Flash with Live Update capability, these devices can hold two independent software applications, permitting the simultaneous programming of one partition while executing application code from the other. This powerful combination of features makes the PIC24F “GB6” family ideal for industrial, computer, medical/fitness and portable applications that require a long battery life, and data transfer and storage without the need of external memory, such as electricity metering, HVAC control, fingerprint scanners and gaming.

The Digilent I/O Explorer USB is a USB peripheral device that allows programmatic access from a personal computer to various external Input/Output (I/O) devices.

 

The I/O Explorer provides a number of I/O devices on the board itself, as well as RC servo connectors, and Digilent Pmod connectors that allow access to devices external to the I/O Explorer.

 

In addition to its use as a dedicated USB peripheral device, the I/O Explorer can also be used as a microcontroller development board. It features two Atmel® AVR microcontrollers, one having USB device capability.
