Last night the Wif needed to do a little bit more studying when I cane up the hill to commute home. Knowing full well that the minute she walked into the house that she would loose all motivation, she wanted to go to a coffee shop. She was thinking the nearby one, the one with junkies and crackheads, the loud one, the one with show service. Don’t get me wrong, it’s perfectly good coffee, just a crap place to study. With my inability to estimate distance, I recommended we go to Ada. In every way it’s a more conducive place to study.
As always even we get there, I end up wandering through and looking at all the kits and books. The Wif loved the Useless Machine. Definitely glad I showed get that one.
The important thing is I got me one of the Sparkfun Parts Boxes. I needed a small parts box, and I needed a grab bag of parts. I had just been looking online at them, figured they had everything I needed and other things that might be fun at a later date. So I payed a bit more, didn’t have to wait, didn’t have to pay for shipping, supported independent business, supported local business. In other words, win.
Now I knew there was a 555 in the box, and I figured that the 555 was the root of my problems, especially seeing as how, without anything hooked up I should see continuity from pins (3 to 5? I wrote it down somewhere), and I wasn’t. When I got home, I took a look at my new treasure and did a fast invento… there’s two 555s. And then I realized. In a previous useful part pack, the Mintronics Survival Pack I believe, I thought I had gotten multiple 555s. I hadn’t. My reading comprehension failed. When I get home tonight, think I’ll swap out an LM358 for a 555.
I need to build a illuminated monocle.
Peter's stuff.
