Hi @jbobrow, bellow is the what worked setup for me on my Linux Mint 18.3, feel free to clean it up and use it in future documentation if you so wish.
Step 1: download Arduino IDE from www.arduino.cc (32bit for 32bit Cpu or 64bit for 64bit CPU)
Step 2: Untar the file into ~/Arduino-X.X.X (Where X.x.x is the version number)
Step 3: Open the terminal and run: ./arduino-linux-setup.sh USER (Replace USER with your linux username)
Step 4: In the terminal run: sudo service udev restart
Step 5: In the terminal run: sudo udevadm control --reload-rules
Step 6: In the terminal run: sudo nano /etc/udev/rules.d/99-USBtiny.rules, when nano opens type the following: SUBSYSTEM==“usb”, ATTRS{idVendor}==“1781”, ATTRS{idProduct}==“0c9f”, GROUP=“adm”, MODE=“0666”
Then press Control + X followed by y then press enter to save
Step 7: reboot the computer
Step 8: Get the Blinks Dev SDK from: www.move38.com/letsdothis and follow the instructions
Happy Blinks Deving,
Lee
