So last week I did a write-up about my ISEB6, parts of which ended up making the rounds on various maker / tech blogs. I noticed a lot of people were wondering why someone would bother doing this? Why ‘waste’ so much time, money, energy, and effort making something like this?
The simplest answer is, for the fun of it.
Sure, there’s a level of enjoyment to be had from simply having the finished product, from using it. There’s the utility of it – it was designed to do a thing, and it does that thing. There’s the sense of novelty, that one might get from any new toy, be it a cellphone, computer, tv, or whatever. In this case all that is augmented or magnified by the fact that I built it myself.
When you build something yourself, you have the sense of achievement, in seeing something through from initial concept to final build. You have the knowledge and experience gained, from learning the hows and whys and whats. And you have the pride of knowing that you made something – you set a goal for yourself, and you accomplished it.
And there’s the sheer fun of solving problems and challenges. Physical computing projects like these give you the opportunity (or the challenge) to work with very limited resources. How many functions can you include, how many features can you code, when you are limited to 32kB in which to fit your entire program? And when you have only 2.5kB of RAM in which to execute that code?
Wearable projects add two more dimensions of limitations: Size and Power. How many features / peripherals can you add without making the whole thing too big / heavy / unwieldy? And how much power does everything draw? How long will it run before you need to recharge, or do you need bigger batteries?
I’ve seen a few comments that basically asked, why not just strap a smartphone to your wrist? The simplest answer there is, that’s not what I wanted. That might work for some people, of course. Find something that someone else has built that’s close enough, or good enough, buy it, settle for it.
Why settle though? I live in a world where if you want a specific product to do something the way you want it, if noone else has built exactly what you want, you build it yourself. Build it yourself and you have exactly what you want, the way you want it. And if it ever breaks, you have the know-how to fix it.
(A close runner-up is, buy something that’s mostly there, then hack it to make it perfect. Add those features, fix those functions, and get exactly what you want that way.)
Stuff does break of course. Especially when you’re building and experimenting and learning, all at the same time. Sometimes it’s part of the fun of the challenge, sometimes it’s less fun but you still roll with it. Last week the OLED screen died, I never figured out why but luckily I had a spare so I just replaced it.
Two days ago the Micro-USB port snapped off the LiPo charger. I consider that a component failure since it’s supposed to withstand plugging and unplugging. I didn’t have a spare charger board, so I’ve contacted the manufacturer to ask about a replacement, and in the meantime I did some delicate solder-surgery to enable me to keep using the broken one, for now. (That was less-fun.)
And since that write-up last week, I’ve made a dozen revisions and upgrades to the software, changed / improved some of the leather work, switched out the dull dark hardware for shiney brass, and added brass snap closures to keep it on my wrist instead of the elastic string I had started with. I still plan to redo the top leather layer to make it more attractive.
That’s part of the fun too – projects like these are never really finished. You can go on improving them, enhancing them, upgrading them, until the next big idea comes along.
