So recently i have purchased a BadUsb ATMEGA32U4 USB as one in this image https://www.ebay.com/p/MicroSD-Virtual-Keyboard-Badusb-USB-TF-Memory-Keboard-Atmega32u4-Module/13011086107 and when i plugged it in it seemed to work fine until i uploaded a script to it and after that itll only turn on when i press the button on the usb i want to reset the usb so i can use it again

Hello, I've been playing with a small circuit for my Bunny... I've put three USB connectors on a small board, 1 for the Bunny, 1 for the Target PC, and a switched one for a small battery bank (I use a cylinder type). I have just run power from the battery bank connector to the Bunny and did not hook up power from the Target at all. With this setup, I can run attacks on USB 2 only devices; and, more importantly pre-boot the Bunny before the attack... Flip switch, wait for Bunny to boot, then plug into Target... I don't use the Bunny for keyboard injection, btw - I still prefer my Rubber Ducky for that. This kind of setup could easily be added to the base Bunny, or as an alternative hardware version - with a single usb jack on the back to accept the battery bank connector. A more sophisticated circuit could be setup to detect if power was available at the Target and allow the battery bank to be removed. Pre-boot Bunny, plug into Target, pull and palm battery. The only complication is that it would be a lot of torque on the Bunny's main connector if the battery had to be left connected for a USB 2 Target...

I have an idea for a tv-b-gone type device but I know nothing on circuits so I could use some help. I want to make a infrared repeater (Code name: The Black Mime). What I want the device to do is have a infrared sensor and save the infrared code onto a attiny85. If the switch for the sensor is off and a button is pressed then I want the infrared transmitter to send the last saved code. If the sensor is turned on after another code is saved then the attiny will reset itself and have no data on it then save the code received. That's basically what I want for this project. If this one gets built and posted then I will keep thinking of projects. Thanks, hypersonic5000
