Troubleshooting Rule #3: Is it working as designed?

wie ist trading212 Sometimes you start by troubleshooting assuming something’s broken, when really it’s just not working the way you expected. Put another way, it’s “working as designed” - but you and the designer miscommunicated, or disagreed.

New robot chassis

So, when I scored $40 of credit on their recent Free Day, I bought it and the relevant accessories. كسب المال مع موقع الويب الخاص بك read more...

PICkit 2 automator

binary options uk trading strategy Since I made my first mod to the PICkit 2 applet source, Microchip completely rewrote the applet. They use .NET, which I consider to be pretty much a virus, but I was considering getting all the MS development tools installed and getting up to speed with C# to work with it.

PIC-based solar engine (PICSE) 2007

My PrayBot project last year needed a “solar engine,” and the quickest thing I could come up with was based on a PIC instead of the more usual BEAM-style solutions. This year I wanted something more efficient. But it still ended up with a PIC, and it’s much more efficient than any of the BEAM designs I’ve tried. Online apotek Atarax read more...

Troubleshooting Rule #2: Is it turned on?

While troubleshooting, another embarrassing discovery is that the thing in question isn’t working because you didn’t turn it on. This rule could come first, as in some sense it’s more basic than Rule #1, but for the simple AC-powered appliance, you have to plug it in before you can turn it on, so I list it second.

Again, there are lots more useful ways to think about whether you’ve turned something on. For instance: http://www.remedy-stores.com/?straysjatina=il-migliore-autopilot-per-seguire-opzioni-binarie&aaa=ac il migliore autopilot per seguire opzioni binarie read more...

Troubleshooting Rule #1: Is it plugged in?

The first in my series of troubleshooting rules:

A surprising number of day-to-day problems are solved when you realize that the thing just isn’t plugged in. Oops.

The obvious sense of “plugged in” is “plugged into the mains supply” - the AC wall outlet.

But there are many other useful senses to look for: anyoption paypal read more...

Weber's Troubleshooting Rules

These rules certainly apply to electrical engineering, and software, but they are also basic enough to apply to interpersonal issues, group dynamics, etc.

  1. Is it plugged in?
  2. Is it turned on?
  3. Is it working as designed?
  4. What’s changed since it worked?
  5. What don’t you know?

Robot Taxonomy

Having been playing with various electronic gadget designs that might or might not be considered “robots,” and recently thinking about buying a Roomba, I was wondering what my own working definition of a robot actually is. Here’s what I came up with while washing the dishes. 24 opzioni binarie read more...

PICkit 2 modifications

piattaforma opzioni binarie demo Note: This page is obsolete, but I’m leaving it up for history. My current solution for automated control is here.

Microchip’s PICkit 2 is a good, cheap PIC programmer. One nice thing about it is that they’ve made the source code available. So you can tweak it if it doesn’t suit you.

In order to integrate it with the SourceBoost IDE, I added this command-line option: buy Viagra online in sweden read more...

Here’s some PIC assembly source code (MPASM) for reading a quadrature encoder. It’s fairly raw and simple, but it works. opcje binarne w złotówkach read more...
