UsbSafe² – Programmable dongle for protecting USB devices from USB hosts and chargers
https://www.electronics-lab.com/usbsafe%c2%b2-programmable-dongle-protecting-usb-devices-usb-hosts-chargers/
USB connections can transfer both information and power. UsbSafe² is a device for protecting USB-connected hardware from both excessive voltage, current and unauthorized data access. Unfortunately, the practice of “juice jacking” (accessing data from a device connected to a public charging station), has become all too common. UsbSafe² provides a unique combination of an anti-juice […]
iBreathe, A Breathalyzer Based on Hexiwear
https://www.electronics-lab.com/ibreathe-breathalyzer-based-hexiwear/
Knowing the amount of alcohol you drunk is becoming easier using the iBreathe Breathalyzer project by Dave Clarke. You just have to blow in the alcohol sensor, then it pings the result to a smartphone app and to the cloud to document it as a table so you can see alcohol intake through time. This […]
A Multi-Use Mini Sensor Platform
https://www.electronics-lab.com/multi-use-mini-sensor-platform/
While developing a smart hardware project, such as control and automation systems, you will almost need to use different types of sensors for collecting and gathering necessary data. LastSamurai had designed a platform that aims to simplify the use of digital and analogue sensors. The platform was developed based on MySensors Hardware, hardware components that […]
ATtiny85 Light Sensor – I2C slave device
https://www.electronics-lab.com/attiny85-light-sensor-i2c-slave-device/
Paweł Spychalski build a photoresistor based daylight meter sensor connected via I2C bus using ATtiny85: I love AVR ATtinyx5 series microcontrollers. They are cheap, easy to use, they can be programmed just like Arduinos and comparing to their size they offer great features. For example, they can be used as remote analog to digital converters […]
Regulator offers independent outputs

Susan Nordyk @ edn.com writes: Housed in a 15×9×2.42-mm over-molded BGA package, the LTM8049 µModule dual-output DC/DC converter from Linear Technology is configurable for a combination of SEPIC and/or inverting operation by simply grounding the appropriate output rail. All that is needed to complete the design are input and output capacitors and a few resistors—a […]
Program AVR Using Arduino the easy way
https://www.electronics-lab.com/program-avr-using-arduino-easy-way/
rik @ riktronics.wordpress.com show us how to program AVR microcontrollers using an Arduino board. Advanced hobbyists like me (and you, of course 😉) love to play with microcontroller. And the most famous microcontrollers for beginners are AVR series from Atmel™. Almost all beginners in microcontroller-world have their Arduino boards lying on work table. Because it is […]
