Can't launch DC Thunder rocket launch from Raspberry Pi

I recently bought a Miss Cheeky Thunder sniper rocket and I want to control it from my raspberry pi.

Using retaliation code ( https://raw.githubusercontent.com/codedance/Retaliation/master/retaliation.py ) I was able to write a small Python script to send commands to Thunder. The move commands and the "stop" command work fine and actually move or stop the thunder. However, when I send fire command "0x10", the launcher does not start and the connection to it is terminated.

I am using standard raspbian os. Has anyone else experienced this problem, and if so, how did you resolve it?

Are you using a powered hub or are you directly connecting the thunder to the pi? I had the same problem and found out that the pi is not putting out enough energy to fire the darts. I have a powerful USB hub and it worked like a charm.

Late answer here ...

The Pi isn't drawing enough current out of the box. However, you can add max_usb_current=1

in /boot/config.txt

and reboot to provide enough current to run Miss Cheeky Thunder Missile Launcher (tested on Raspberry Pi 2). Make sure you have a large enough power supply.



Check the settings with vcgencmd get_config int

.
