Absolutely! The RGB lock would have way more security, and I had some white high-brightness LEDs that I was tempted to toss in there. The photoresistors would just have three different thresholds, which would just be a little change to the code, but the small effort for more security is definitely a bonus!I had a friend who told me to make guides for the crystal, and we even discussed a 'card' that could be hitched to a motorized track so that it could scan the card over a set interval to get a ridiculously secure lock. You can't pick it because there's no indication of success from any visual or auditory queues! Unfortunately it does require some more precise manufacturing methods.
I totally agree! That would be so cool to see
Thank you! You have some crazy cool projects yourself!
