Graham Prophet @ eedesignnewseurope.com discuss about a 18W USB power supply reference design. This joint reference design describes an 18W, USB PD compliant, AC-DC power converter. The design, titled DER-567, pairs the WT6630P USB Type-C PD controller from Weltrend with Power...

Lukas Fässler from Soldernerd published a project showing how he built a PIC-based beacon keyer: This is likely the first ham radio related project that I document here on this blog But my very first PIC project was a beacon keyer that I made for my father, HB9BBD. That was in...

Current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 Op-amp, ½ of  LM358 op-amp used as an amplifier for low voltage  and 2nd 1/2 LM358 op-amp used as comparator which provides over current TTL output, trimmer potentiometer...

Michael Dunn @ edn.com has compiled a list of software that most enginners should be aware off. We're living in a golden age of software, where many useful programs are available – for free! Let's survey some of what's out there that just might interest an engineering crowd...

by Max Maxfield @ eeweb.com: A little while ago, it struck me that I was getting tired of explaining what FPGAs are and how they work their magic to those of my chums who — thus far — have worked only with microcontrollers (MCUs), so I decided to write a three-part mini-series of...

Susan Nordyk @ edn.com: A single-chip 2.6 A driver for brushed DC motors, STMicroelectronics’ STSPIN250 targets battery-powered portable and wearable applications. This low-voltage, energy-efficient driver integrates a power MOSFET bridge and fixed off-time PWM current controller...

by Susan Nordyk @ edn.com The MAX17055 single-cell fuel gauge from Maxim not only eliminates battery characterization, but also keeps SOC (state-of-charge) error to within 1% in most scenarios. With its ModelGauge m5 EZ algorithm, the device provides tolerance against battery...

The 6 Channel RF Remote Controller designed using CC2500 RF Transceiver modules and PIC16F1847 micro-controller from microchip. Transmitter provided with 6 tact switch, 4 Address Jumpers to pair multiple unit so they don’t interfere with each other. Board provided with power LED,...
