INTELIGENT POWER MODULE (IPM) BOARD FOR BRUSHLESS MOTORS
Posted on: 09 Jan 2018
Intelligent Power Module (IPM) board has been designed using FSBS5CH60 IC from Fairchild, which provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, over-current shutdown, […]
Lowest power magnetic switch uses nanoamps
Posted on: 07 Jan 2018
Crocus Technology is a developer of ‘exotic’ magnetic technologies – spin electronics and Tunneling MagnetoResistance (TMR) – for devices such as magnetic sensors, where its technologies can offer greatly increased sensitivity for very low power usage. The company is introducing its CT832 Digital Magnetic Switch, in the CT83X series, a multi- function switching device with […]
MP3 MODULE & RTC DS1307 SHIELD FOR 28/40 PIN PIC DEVELOPMENT BOARD
Posted on: 05 Jan 2018
MP3 Shield has been designed for various applications related to voice record and play using MP3 module with memory card storage, this shield can be used as standalone mode or Digital mode by serial interface. In standalone mode it can play 16 messages with couple of other functions, Standalone operation possible by connecting resistors and […]
2.7V to 38V/500 mA low noise buck-boost charge pump
Posted on: 04 Jan 2018
LTC3246 is a low noise buck-boost charge pump with integrated watchdog timer capable of up to 500 mA of output current. It uses multimode switched capacitor conversion to maintain regulation over a 2.7V to 38V input voltage range and produces a regulated 3.3V, 5V, or externally adjustable (2.5V to 5V) output. Internal circuitry automatically selects […]

Posted on: 03 Jan 2018
Opendime is a small USB stick that allows you to spend Bitcoin like a dollar bill. Pass it along multiple times. Connect to any USB to check balance. Unseal anytime to spend online. Hopefully everyone who needed an Opendime for Christmas has got it under the tree already, because we are now out of stock! […]
NetWorker – an advanced web server with a microcrontroller
Posted on: 02 Jan 2018
An Internet connection would be a valuable addition to many projects, but often designers are put off by the complexities involved. The ‘NetWorker’, which consists of a small printed circuit board, a free software library and a ready-to-use microcontroller-based web server, solves these problems and allows beginners to add Internet connectivity to their projects. More […]
Tiny Face Watch
Posted on: 01 Jan 2018
This is the third in my series of minimalist watches based on the ATtiny85. This version displays the time by drawing an analogue watch face on a miniature 64×48 OLED display. It uses a separate crystal-controlled low-power RTC chip to keep time to within a few seconds a month, and puts the processor and display […]
Build mobile & IoT apps without hardware or firmware development
Posted on: 31 Dec 2017
Based on Nordic Semiconductor’s nRF52832 Bluetooth low energy System-on-Chip (SoC), this development kit incorporates nine different sensors plus a microphone and speaker, and enables app developers to configure, test, and demonstrate Bluetooth low energy IoT devices linked to mobile apps and Cloud platforms without needing RF firmware coding skills or development tools The Nordic Thingy:52 […]
Bosch glue pen teardown
Posted on: 30 Dec 2017
Intro My cheap plug in hot glue gun died and looking for a replacement I found this: the Bosch GluePen What does it do? it’s a hot glue gun for 7 mm glue sticks that warms up in 15 seconds. Charges via micro USB. Much better than my old one that needed ~5 minutes to […]
RX/TX SEQUENCER
Posted on: 29 Dec 2017
Much like the beacon keyer presented here earlier, this RX/TX sequencer is a simple but useful little device. Its typical use is in ham radio applications when a separate power amplifier (PA) and/or a sensitive low-noise pre-amplifier (LNA) is used. Care has then to be take to safely transition between RX and TX states – and that’s where […]
