This isn’t a specific project, so much as a pointer to a budding new site. Puppet Circuits is the project of [Raphael Abrams], one of the co founders of NYC Resistor. As you can probably guess, he has been posting about the circuits he uses in his animatronic puppets. I faces all kinds of problems since may of the systems are to be worn and have to endure some pretty rough treatment and still perform well. Very interesting stuff to read about.
I faces spealing probmels too
Wow at the half way point does that get hard to read/understand or is it just me.
I believe OP-AMPS are under utilized.
Modern hackers usually opt for a digital solution that is often more expensive, more complex (overkill), and may end up taking longer to program.
Why do you think this is?
My theory is that digital solutions align more easily with human thought processes.
Perhaps digital is more a science and analog more an art and those into electronics tend to favor the former.
(incidentally I never got very good with Op-Amps and stopped using them a number of years ago, but I’d like to get back into using them again.)
@simonious
why even bother? attiny’s are like a buck each.
@Simonious: Because for some reason, nearly anything analog scares the hell out of people. I don’t know if it’s because you have to think a bit more, or put the work into making a robust design, but this seems to be the general case.
@mrgoogfan: That’s exactly the problem. What’s ‘easiest’ is not always the ‘best’. What about the cost of labor to write the program? Debugging? Noise isolation, etc? What if, 20 years down the road, they stop making attinys altogether? Serviceability? These issues don’t seem to be taught anymore..
I really enjoyed Op-Amps in college and was looking forward to using them more after that class, but after that professor retired they were never really talked about again and I haven’t come across many people using them since college.
