TI glass breakage detector design and sample kit offer

TI is making samples available of of components used in their new glass breakage detector. This simple glass-breakage detector solution describes a simple glass breakage detector using the MSP430F2274 and was developed to operate at low power, allowing long battery life. The algorithm is based on the spectral analysis of a typical glass breakage signal […]

TI LDC1000 inductance-to-digital converter

Manuel Garbe draws attention to a new inductance-to-digital converter chip known as the LDC1000 from TI. This should eliminate the need for Hall effect sensors and magnets, providing contactless sensing with immunity to non-conductive interferences. Here’s a link to a good explanatory article from EDN. The datasheet can be downloaded from TI. Via the contact […]

Change HC-05 Bluetooth module settings via AT commands

TechBitar writes, “This is a utility that shows how to change the settings of the ubiquitous HC-05 Bluetooth module using the AT command set. The HC-05 comes with a rich set of AT commands to perform various tasks such as changing the module’s default settings including changing the pass code, the device name, and the […]

One dollar variable fan controller

Mountaindude has been spending some time lately working on 12V fan controllers and thought he’d share his experiences so far. “While trying out various computer and network gear, I quite often find the fans too loud. They are of course there for a good reason, but experience tells that the device usually works just fine […]

Breakout board uses HB100 doppler motion sensor

limpkin has been working on a dev board for the HB100 microwave sensor. He developed a breakout board that allows the module to operate as a motion sensor. “I’m sure you’re quite familiar with the Doppler effect: you send an RF signal at a given frequency to a target, and if this object/person is moving […]

With TI wireless devices being encountered from time to time in your hardware hacking it’s important to be able to recognize the types of chips and their associated capabilities. TI has a free Wireless Connectivity Guide available covering their offerings for various wireless technologies including mesh and IP networks, personal area networks, locationing, RF sub-1 […]

Diamond package from NXP, the world’s smallest logic package

Drone refers us to this short video from NXP on very small pitch parts (0.35mm) and the challenges in mounting them. NXP debuts their new Diamond package which they report is over 25 percent smaller than their XSON package (suffix GN), previously the world’s smallest package. The video point out that this design retains the […]

The MAX7219 LED display controller – real or fake?

John Boxall over at Tronixstuff has a detailed review of the differences between the real MAX7219 and the others: A few people have been asking me of late, and there’s only one way to find out … so over the last month I ordered eight random “MAX7219s” from different suppliers on ebay and will compare them […]

HackManhattan’s Nordic nRF51822 breakout board

Guan Yang of HackManhattan informs us of his efforts in working with a Bluetooth low energy component: This amazing component is the Nordic nRF51822 that was released last year and is now available for order from Mouser. It’s a Bluetooth Low Energy system-on-chip that includes a transceiver and a Cortex-M0 microcontroller. Here’s a breakout board […]

24VAC to 5VDC Conversion

Ray Wang wrote this post about voltage conversion from 24VAC to 5VDC. Voltage conversion from 24VAC to 5VDC is quite useful, because a lot of home automation devices use 24VAC, including sprinkler solenoids, home surveillance systems etc. Having a conversion module makes it easy to use a single power supply, without a separate 5V adapter […]
