I think AtP is in a dead tie with Robert’s “New Products” (don’t head back to Chernobyl just yet). That’s one of the first things I check for every Friday morning, and I’m disappointed if it’s not there right away. It makes my day.
Actually, all the SF newsreels are great. Keep them coming!

Well, if kind Mr. 408458 (below) is right, there may be hope. That function generator feature is a great addition. And I do know it’s faster. Given that the old scope’s full retail price was about $160, and went on special at $89, then maybe if Parallax puts this new one on sale occasionally too, I may snap it up. Miskatonic’s right, in that it’s a good everyday scope.
They’re using the excellent Parallax oscilloscope. But naturally, they discontinued it. They used to offer it on sale for about $89, and was even at $49 at close-out. It uses your PC for the display. It’s not for really high frequency stuff, but for troubleshooting signals between chips (or LEDs, as here), it was fantastic.
They’re offering a new version, but it’s a lot more expensive ($200), and out of stock at present.

Sure. I put the executable in the same directory. You’ll need the .NET runtime unstalled to run it. It assumes you’re in COM port 13 (that’s just where I’ve been testing), so you’ll get an error at startup (unless you happen to use 13 as well). Just keep going, and set the port to whatever you are using.
If you want to tweak the code, I included the whole C# project too. It was done under C# Express, so to compile it under regular Visual Studio, you’d just have to start your own project, and copy in the files. If that’s a pain, I could also produce one for that version too. I think I still have it around.
Here’s a link to an Arduino program I wrote that reads the wind speed and direction, and sends it back to the PC via the UART in readable text. The device works great, but the provided documentation isn’t much (to put it kindly), so even if you want to develop your own code, this might clear a few things up (or make it worse!).
I also have a C# program that reads the COM port, and logs it all to a disk file (with time stamps) for later statistical processing (or whatever). Let me know if you’re interested, and I’ll post that.
No public wish lists :(
