Dream Bigger, Predict The Future

I’d love to tell you that I’m never wrong, but I’ve been wrong a lot. Remember the Arduino? When it was brand new, I thought it was some silly collection of libraries and a drop-down menu for people who are too lazy to just type out their own #include statements. Needless to say, it launched about a million hacks and brought microcontroller programming into the mainstream. Oops.

Similarly, about fifteen years ago, I saw an educational project out of MIT’s Media Lab. It consisted of a bunch of blocks that had LCD screens on them and would interact with each other when put together. The real hook, though, was that each block had an accelerometer inside, so you could “pour water” out of one block into another, for instance.

At that time, accelerometers were expensive, even in quantities. Even one of these cubes must have cost $100 at the time, much less a whole set. Accelerometers were so expensive that I wouldn’t have thought about incorporating one into a project, much less a dozen, so I ignored them for hacker purposes. Then came the cellphone and economies of scale. Today, even in chip shortage times, they’re readily available for around $2 each, making them useful for exactly this kind of “frivolous” use.

From the Arduino experience, I learned to never underestimate the impact of what seem to me to be “small” conveniences. (And maybe more so, the value of the tremendous common effort from the community.) From the MIT accelerometer story, the moral is that some parts will get drastically cheaper in the future, so you shouldn’t necessarily exclude the cool new sensor from your design repertoire. After all, ten years ago, nobody would have thought that we’d have laser time-of-flight rangefinders for less than a hamburger.

What new components are fantastically useful, or full of potential, that might be cheap enough in the future to make them also worth looking into? Swing by Hackaday tomorrow morning and join in the conversation!

Path To Craftsmanship: The Art Of Being Wrong

Every technical person knows, unlike artists and politicians, that they can be provably wrong; at least to a degree. Math tells the truth. Coupled with this knowledge is an ego which is often entirely based on our output. If our mechanism works, we feel good because we are provably good.

A disclaimer.
It didn’t stop Scott Adams from writing four books full of it and it won’t stop me.
from Dilbert: Advice

Unfortunately, unlike the robots we build or the simple minds we spin out of code, we are still human at the end of the day. When we feel the sting of being wrong we often respond poorly. Some of us slip into depression, claiming it all and dredging up a few other mistakes from our past along for the ride. Some of us explode into prideful rages, dropping our metaphorical shorts to show that this one fault is no fault at all compared to a history of personal majesty. Others become sullen and inward. Others ignore it all together. Others yet strike out at those around them leaving unpleasant barbs. The variations are endless, but I do think there is an ideal to be reached.

Despite the risk that the nature of the things I’ve learned will reveal exactly what kind of arrogant sod I am, I’ll give it a go anyway. I’ve made many mistakes, and I have many more to make, but these are some of the things I’ve learned. I’ve learned them all in technical fields, so I’m not sure how broadly the advice applies, but luckily this is Hackaday.
