SMD version - Bluetooth Module Supply and Booster board for tube radio
Caldeira Oct 09,2024
The SMD version of my Tube Radio Bluetooth Module boardsThe definitive Bluetooth Module PCB to seamlessly add BT to a tube radio, with no buzzing noise, and signal booster. It also incorporates the magic eye switch, that automatically switched off the supply to the board when listening to radio.The board takes power from the radio's heater supply, and provides power to a commercially available module, while boosting the output from this module to match the level required at the Phono input of a ...

Magic Eye Switch for Bluetooth Boards
Caldeira Aug 14,2024
Magic Eye Switch for Bluetooth BoardsThis is an add-on to allow the Bluetooth Boards that I designed previously to be switched on or off using the magic Eye tube's B+ signal. The Magic Eye is normally ON when radio is selected, and OFF when Phono is used. This allows us to only switch the Bluetooth Module ON when Phono input is being used, to reduce noise pickup when listening to radio.

Advanced BadUSB with WiFi and SD Card Storage
Ekşi Jun 03,2024
When an ordinary BadUSB is plugged into a computer, it executes previously specified commands. It provides the user with limited access and does not allow additional commands to be added later. Additionally, the biggest problem is that the computer does not recognize the device as a USB flash drive. This allows a conscious user to easily realize they've fallen into a trap.With the Advanced BadUSB project, the user can remotely control the BadUSB thanks to the USB communication and WiFi/Bluetooth...
