Portable temperature, humidity and ambient light datalogger
https://www.electronics-lab.com/portable-temperature-humidity-ambient-light-datalogger/
Jesus @ jechavarria.com pointed us to his latest project, a portable temp, humidity and ambient light datalogger. Hi all! I’m continuing here with the last board I design and now I’m continuing testing. It’s a battery-powered small datalogger based on a PIC18F2620 microcontroller. The idea comes a few months ago, talking with a friend. He […]
Single-chip end-to-end security for IoT devices connected to the Amazon cloud
https://www.electronics-lab.com/single-chip-end-end-security-iot-devices-connected-amazon-cloud/
Max Maxfield @ embedded.com discuss about IoT security and single chip solutions to this issue. The Internet of Things (IoT) has the potential to change the world, but only if it’s secure. Securing the IoT is currently one of the greatest challenges for the creators of IoT devices and the providers of cloud services. In […]
openSip+Puff for people with limited mobility
https://www.electronics-lab.com/opensippuff-people-limited-mobility/
Low-cost, open-source “sip-and-puff” interface to enable new methods of expression for people with and without limited mobility. by Jason Webb: Commercial sip and puff devices have been available for quite some time but are generally prohibitively expensive, highly specialized, limited in expressivity, require poorly-written and restrictive software and rely on clunky, out-of-date hardware that makes […]
SunDuino – Run your C application using solar power
https://www.electronics-lab.com/sunduino-run-c-application-using-solar-power/
SunDuino is a Single Board Computer with integrated Battery Charger, Voltage Regulators, I2C, Digital and Analog IO. It’s main benefit is that it can run a compiled C app for years on a small battery or forever using built in solar charger. A background RTOS provides SLEEP functions for reducing operating current to 100ua while providing 125ms periodic wakeups. […]
FemtoFET – 20V 500mA 0.6×0.7mm MOSFET From TI
https://www.electronics-lab.com/femtofet-20v-500ma-0-6mm-0-7mm-mosfet-ti/
Texas Instruments “TI” recently announced FemtoFET series. There are N-channel MOSFETS like CSD15380F3 and P-channel MOSFETS like CSD25480F3 and CSD23280F3 in this series. These transistors are SMD (Surface Mount Devices) available in a very small package, the land grid array (LGA) package. To explore this family we will highlight the FemotoFET MOSFET CSD15380F3. It has […]
Zener Diodes In Theory and Practice
https://www.electronics-lab.com/zener-diodes-theory-practice/
David Jones made a tutorial on the fundamentals of zener diodes over his EEVblog youtube channel. David started the tutorial comparing between zener and regular diode. Both have the same characteristics and same I-V chart, but zener is designed to work in the negative voltage region.”In theory” the regular diode can work in the negative […]
Magnetic field sensor using AD22151
https://www.electronics-lab.com/magnetic-field-sensor-using-ad22151/
Magnetic field sensor project using AD22151 IC from Analog Devices, The AD22151 is linear magnetic field transducer. The sensor output is a voltage proportional to a magnetic field applied perpendicularly to the package top surface. The sensor combines integrated bulk Hall cell technology and instrument technology to minimize temperature related drifts associated with silicon Hall […]
