Power USB devices from a vehicle
https://www.electronics-lab.com/power-usb-devices-from-a-vehicle/
Automotive accessories such as PNDs (portable navigation devices) usually receive their power or charge using a simple adapter that a user plugs into a cigarette lighter. Sometimes, however, you may want to power or charge two devices at once. The circuit in Figure 1 can handle that task. IC1 generates 5V from any 7.5 to […]
Meet Binho Nova – the Multi-Protocol USB Host Adapter
https://www.electronics-lab.com/meet-binho-nova-the-multi-protocol-usb-host-adapter/
While it has become a norm for embedded firmware developers, tinkerers, and DIY electronics hobbyists to have multiple adapters for different communication protocols, the challenges associated with moving around with all the adapters can be quite the drag. The new Binho Nova Adapter is trying to change this by serving as a Multi-Protocol USB Host […]
Dual USB Host/Hub Output with Constant Current Limit/Protection
https://www.electronics-lab.com/dual-usb-host-hub-output-constant-current-limit-protection/
This project has 2 outputs that enable us to power up 2 USB devices simultaneously from an input supply of 12-30V DC. The idea of this project is to have safe power for USB powered devices.

The super tiny USB Rubber Ducky
https://www.electronics-lab.com/super-tiny-usb-rubber-ducky/
We’ve seen several Security-based hardware projects from Koko (@justcallmekoko) in the past, including the Masterkey keylogger which we explored a few days back. Looking through his projects on GitHub today, I stumbled on another security-based project called the Tinyduck. A cheap alternative to the popular Rubber Ducky, the Tiny Duck is an Attiny85 microcontroller-based pentest […]
