Introducing ChipHeadBang

There are a number of widely used methods to connect microcontroller projects to USB, all of which are not entirely satisfactory: The commonly used FTDI chips are somewhat expensive, and their manufacturer has made some unpopular decisions with their driver support (although technically, the FTDI drivers work quite well). Atmel also offers microcontrollers with built in USB, but those also tend to be a bit ...

Liquid Cooling Moves onto the Chip for Denser Electronics

Using microfluidic passages cut directly into the backsides of production field-programmable gate array (FPGA) devices, Georgia Institute of Technology researchers are putting liquid cooling right where it’s needed the most – a few hundred microns away from where the transistors are operating. Combined with connection technology that operates through structures in the cooling passages, the new technologies ...

Heart On-A-Chip Beats

PORTLAND, Ore. — Living beating hearts on-a-chip were recently created from pluripotent stem cells discovered by 2010 Kyoto Prize Winner, Shinya Yamanaka. Bioengineers at the University of Berkeley aim to create all of the human organs on-a-chip then connect them with micro-fluidic channels to create a complete human-being on-a-wafer. "We have learned how to derive almost any type of human tissue from skin ...

A data-acquisition system on a chip

Multifunction data-acquisition systems have been around for a long time as stand-alone instruments, plug-in cards, cabled computer peripherals, and embedded in systems. Such systems are often designed with separate ADCs, DACs, and digital I/O devices. Many microcontrollers include ADCs and DACs, but that locks you into using that device. The AD5592R from Analog Devices combines all of these I/O functions, l ...

Dual 3A PSU on a Chip

Intersil have introduced a single chip just 9 x 6.5 mm which contains just about all the control features (including the output stages) needed to build a dual 0.8 to 5 V power supply with 3 A per channel output capability. The ISL8203M can also supply 6 A in current sharing operation. The ISL8203M is an integrated step-down power module optimized for generating low output voltages down to 0.8V.  The input s ...

Microchip Technology

Summary The MCP6V01 auto-zeroed op-amp features an ultra low offset voltage (VOS) and high common mode rejection ratio (CMRR), which makes it applicable to temperature measurement. The MCP6V01 thermocouple auto-zeroed reference design demonstrates how to measure electromotive force (EMF) voltage at the cold junction of the thermocouple in order to accurately measure temperature at the hot junction. The diff ...

Standalone Arduino chip on breadboard

If you're like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects. The problem was that I'm such an electronics newbie that I didn't know where to start. After reading through many web pages and forums, I was able to put together this Instructable. I ...

General Instruments SP0256-AL2 English Phoneme Speech chip & an Arduino

The GI SP0256 chip is an early 1980s bit of technology. It's a 5V (to 7V) NMOS chip which is compatible enough with the 5V TTL circuity common in that era. 5V TTL disappeared for a while, then came back with the Atmel _28-based Arduino boards, many of which run at 5V. The SP0256 chip contains a [crude] electronic model of the human voicebox, and the -AL2 variant comes with 59 English language phonemes built ...
