USB Volume Control and Caps Lock LED
https://www.electronics-lab.com/usb-volume-control-caps-lock-led/
p_leriche @ instructables.com build a USB volume control which is simple, cheap and extensible. Check it out: I’m not the first person to publish an Instructable for a USB volume control, but I think this one is about as simple and cheap as it gets, and at the same time can be extended at minimal […]

pickandplace.wordpress.com writes: I started with making the TMP102 temperature sensor work. Nothing to say in particular, it’s just an other I2C-small-package-sensor. Or rather SMBus, but apart from the minimum speed clock requirements on the SMBus, the two protocols are alike. Designing a simple and cheap temperature logger – [Link]

30 Minutes HIV Detection Using USB Stick
https://www.electronics-lab.com/30-minutes-hiv-detection-using-usb-stick/
In partnership with DNA Electronics, Imperial College London researchers had developed a revolutionary USB stick that can detect HIV in the bloodstream. In order to detect the virus, it’s enough to use a drop of blood. Then the USB stick generates an electrical signal that can be read by a computer, laptop or handheld device. […]

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 […]
DIY USB 5V Solar Power Bank
https://www.electronics-lab.com/diy-usb-5v-solar-power-bank/
Abdulgafur tipped us with his latest project, a 5V solar powered power bank. The circuit consists of two stages, the first stage is the battery charger stage based on MCP73831 and the second stage is the step up converter based on LT1302-5 which converts the battery voltage to 5V. Solar energy is renewable, free, widely […]
MPPT Solar Charger Design based on PIC18F26J50
https://www.electronics-lab.com/mppt-solar-charger-design-based-pic18f26j50/
Lukas Fässler shares his Maximum Point Tracker Solar Charger Design based on PIC18F26J50: At the core of the design is a PIC18F26J50 in a 28 pin SOIC package. It’s capable of running at down to 2.15 volts and consumes extremely little power when running at lower clock speeds. And apart from that it features USB […]
