Hands-on with the BBC micro:bit
Hands-on with the BBC micro:bit
01.02.2017 · Articles · Microcontrollers
It’s been a long wait, but our latest single board computer for review is finally here! The BBC micro:bit, given free to every seventh-grade British child, has landed at Hackaday courtesy of a friend in the world of education. It’s been a year of false starts and delays for the project, but schools started receiving shipments just before the Easter holidays, pupils should begin lessons with them any time now, and you might even be able to buy one for yourself by the time this article goes to press...

Electrolytic Capacitor-Based Data Backup Power Solution for a 12V System Regulated from 5V to 36V Input
Electrolytic Capacitor-Based Data Backup Power Solution for a 12V System Regulated from 5V to 36V Input
31.01.2017 · Circuits
Data loss is a concern in telecom, industrial and automotive applications where embedded systems depend on a consistent supply of power. Sudden power interruptions can corrupt data during read and write operations for hard drives and flash memory. Often, embedded systems need just 10 ms to 50 ms to backup volatile data to prevent loss...

TI technology extends flight time and battery life of quadcopters and industrial drones
30.01.2017 · News
Texas Instruments introduced two circuit-based subsystem reference designs that will help manufacturers add flight time and extend battery life to quadcopters and other non-military consumer and industrial drones used to deliver packages, provide surveillance or communicate and assist at long distances...
High-fidelity triangle-wave generator consumes only 6 µA
High-fidelity triangle-wave generator consumes only 6 µA
29.01.2017 · Circuits
Ideal triangle waves involve infinite d2V/dt2, so high-fidelity triangle waves entail very high bandwidths. Micropower circuits have fairly low bandwidth, so generating good triangle waves with such circuitry becomes problematic. The circuits show two methods of generating triangle waves...
e2v reveals the world's first K-band capable Digital-to-Analog Converter
e2v reveals the world's first K-band capable Digital-to-Analog Converter
29.01.2017 · News
e2v announces the launch of the, a 6 GSps Digital-to-Analog Converter which can achieve clean signal generation up to 26.5 GHz. The new EV12DS460 from e2v is the world’s first DAC to perform signal generation directly in the K-band frequency, removing the need for signal up-conversion and the costly mixers that perform this task...

MOSFET-based Joule Thief steps up voltage
26.01.2017 · Circuits
A simple blocking oscillator circuit can be used to step up voltage using properties of coil inductance. Such a circuit is more commonly called a Joule thief...
Multiphase 60V Synchronous Boost Controller Provides up to 97% Efficiency with Input & Output Protection
Multiphase 60V Synchronous Boost Controller Provides up to 97% Efficiency with Input & Output Protection
26.01.2017 · News
Linear Technology Corporation announces the LTC3897, a multiphase synchronous boost DC/DC controller with input surge stopper and ideal diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus the single-phase equivalent...
