I recently bought a pair of the Macetech RGB LED Glasses and, after playing with them out of the box for a while, decided to start modifying the source code to display my own patterns. Unfortunately, I am only able to upload some of the time (sometimes I hit the "upload" button and it works, sometimes it does not and I try and unplug and replug, etc.). I keep getting the avrdude stk500_getsync(): error. After some research, according to the official getting started on hacking document put out by macetech, the USB cable shipped with the glasses can sometimes be too thin for the computer to detect the glasses on the serial port. It says you can fix this error by either using a bigger cable, or turning the brightness down on the LED's. Unfortunately, I got to these solutions too late, and have already put the program in a bit of a stall where the LED's are stuck on full brightness whenever I plug the glasses into my laptop. I have a thicker cable, but it does not seem to upload unless, I assume, I turn the LED brightness down (which I cannot do until I reupload the program to fix the glasses). The arduino used is an Arduino Pro Mini 328 (5.5V). Any help or guidance torwards a solution would be much appreciated. Thanks!
