Enables contactless temperature measurement in portable and consumer electronic applications

Developed through TI’s expertise in MEMS technology, the TMP006 is the first of a new class of ultra-small, low power, and low cost passive infrared temperature sensors. It has 90% lower power consumption and is more than 95% smaller than existing solutions, making contactless temperature measurement possible in completely new markets and applications.

Earlier this week we posted about Carlos Agell’s project which allows the acquisition of analog camera images by an Arduino. Carlos has updated this project for use with a Processing sketch instead of the costly LabVIEW required in the original design.

Using the Bus Pirate to read the SVP supervisor power on password off an IBM T30 Thinkpad: [via]

A friend of mine recently came upon an old IBM T30 Thinkpad at an auction for $40. Bringing it home, he found that there was a power-on supervisor password. This can’t be reset by removing the battery, as the pswd is stored on an EEPROM on the motherboard….. So it came to me!

I recently purchased a Bus Pirate v3 from Seeedstudio, and decided to give it a quick test run..

Dmitry Grinberg had a few PIC12F1840 MCUs lying around, and wanted to use them in some type of IR remote control project. He decided to construct a remote control mood light using the PICs in both transmitter and receiver. Four high-brightness LEDs (White, Red, Green, and Blue) are used to combine to form different colors in the receiver unit housed in a jar, along with a 38 kHz IR receiver module. The commands are generated by a PIC (housed in a gutted remote control housing) and transmitted via IR LED.

As detailed in this report, IBM has announced their first graphene integrated circuit. Graphene’s structure of one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice make it one of the thinnest semiconductor materials.

Further development using graphene should open the door to greater practicality of flexible electronics. While this technology is not expected to begin displacing conventional silicon circuits for a few years, when it does it should lead to bendable, transparent circuit boards revolutionizing the integration of embedded systems into common everyday items.

PocketPico Picoammeter is a new, USB-connected; very low current measurement device for DC current from 20pA to 2mA. Tiny (2.7” × 1.4” × 3.7”), lightweight (8oz) PocketPico Picoammeter eliminates harmful switching spikes and reads at a rapid 15,000 samples per second. Perfect for lab test setups, PocketPico Picoammeter’s high accuracy, fast speed, and single measurement range brings new features previously unavailable in other picoammeters, like small size, single 20pA – 2mA measurement range at 15,000 Sa/s, high accuracy (±0.5%) and resolution (4½ digits), protection against voltage transients, etc.

PocketPico Picoammeter is dedicated to the task of measuring very low electrical current in optoelectronics, ion and electron beam monitoring, materials resistance testing and more. When connected to a PC, PocketPico Picoammeter accurately measures current from 20pA – 2mA and displays it using the free Windows-compatible easy-to-use PocketPicoReader software on the PC’s display.

PocketPico Picoammeter is one of the easiest and most affordable ways of measuring a wide range of extremely low current. Simple to integrate with existing lab tasks, it avoids using bulky equipment simply to take low power measurements, especially for field use. PocketPico Picoammeter could potentially save users thousands of dollars on instrument costs, software licenses and expensive data acquisition equipment.
Applications for PocketPico Picoammeter include: photodiode current and dark current measurement, ion beam monitoring and measurement, SEM and TEM beam current measurement, optical fiber alignment, component, sensor, and device I-V characterization, materials resistance testing, leakage current testing, analog and mixed-signal circuit testing & analysis, teaching labs, product demonstrations, etc.

Oscium’s iMSO-104 hardware offers to turn your iPhone, iPad, or iPod Touch into a 12MSPS digital oscilloscope with an analog bandwidth of 5MHz. For folks like me with limited desk space & shifting work environments, that’s an interesting offer indeed. Oscium sent over a test model to take for a spin, so onto the spinning!

NEC and a researcher from Japan’s Tohoku University, Professor Hideo Ohno, are working on a power chip that solves a pretty big problem: completely eliminating electricity consumption of electronic devices that are in standby mode. The key piece of technology here is CAM, the world’s first content addressable memory.

This non-volatile memory will be built into the control circuits of TVs, computers and other devices and stores data even when the power is turned off. In other words, constant standby power to maintain data will not be needed anymore (the English press release goes into more technical detail). The picture above shows a prototype power chip.
