Which side is the correct side? left, right, or it depends on the circumstances?Whichever side means you're not constantly swerving to avoid trucks.
If you were proposing some smart way of driving cross country to arrive sooner and use less fuel then we might listen but you're not. You're just saying that driving on the wrong side is possible under some circumstances.
Maybe so, but:
a) You're constantly dodging trucks (and one day they will get you)
b) You're not going to arrive at your destination any sooner, so why bother?
c) You're using more gas and wearing out more brake pads and tires. You'll get through more cars than people who just drive properly.
Have you noticed that all your analogies paint me as reckless? dodging trucks, and driving on the wrong side of the road. I would prefer it if you try to make up analogies that are less biased, because I dont like it when people try to passively insult me.
In your car analogy, do you drive half the speed limit, because its safer? it is safer isnt it, so why dont you drive half the speed limit. Are you unconcerned with safety? Are you a reckless person driving the maximum speed limit, or are you interested in safety, and drive half of the recommended maximum speed limit?
In the case of the charlieplexed RGB cube that uses no current limiting resistors (I assume this is what we are all talking about here...)
Its more like avoiding the traffic entirely, by taking the train instead. You can build this cube, and get it running in a very short period of time, it does not require any math, knowledge of ohms law, watts law, and you dont have to pour over dozens of datasheets making tons of calcualtions. It uses 2 different parts, LEDs and 1 microcontroller, so there are only 2 datasheets needed for the entire cube. Its not like dodging trucks, or driving on the wrong side of the road, its more like taking the train or flying.
Im not going to try to answer questions about someone elses project, its not my business, I dont have all the info and details that they have, so you should ask them, instead of me.

I would love to see 1000 beginners building charliecubes, we could have a lot more data to help build better cubes. Right now, I've only seen a few charliecubes on the internet, so there is very little data.
Making up numbers based on nothing but your feelings isnt really any data. I have 2 cubes that have been running for months, one has resistors (now...) the other still doesnt. Its a very small sample, but the only data I have looks pretty good so far. Durable enough to sustain thousands of hours of service makes this design viable in plenty of circumstances.
Right now, I am planning on setting up a test rig to run some LEDs with some transistors, because I cant figure out what size base resistor to use with a sot23 2n2222 transistor, yes very common part, being used in a very common way. I have researched and calculated, and come up with too many different answers, and very little confidence that any of it is accurate.
so, I'll spend the day building some stuff, measuring, changing, measuring, until I get a good idea of what the real world statistics, which are often end up very different than the calculations.
