Re: Hints Please: 40+ flashing LED project

The shift registers seems like a good place to start for info. The LED strips are cool, but not what I have in mind. I want more flexiblity on placement and number. Plus at more then $1 per light it is a little on the steep side. My background is programming, so the more suggestions the better. Anyt...

Hints Please: 40+ flashing LED project

Here is my project idea: I want to replace the christmas light strings that run along the shelves in my living room with a series of LED's with a Raspberry PI controlling when they come. Having accomplished that task it would be nice to have individual control to flash them on and off in different p...

Re: Is the A+ the Smallest PC in the World?

Phiffftle on both of you. :-) Again, I have to wonder at the insistence on pidgin holing something and then defending the fact that it should stay there. My original contention that the A+ can be considered a PC still stands. You can plug in a keyboard, mouse and monitor, you can obtain a pre-flashe...

Of course it does. One need only plug in those devices. The board mentioned above would require soldering of connectors to get the job done; although I was still willing to consider it as a possibility once those connectors were put in place. Seriously, where does the joy come from attempting to pok...

Re: Is the A+ the Smallest PC in the World?

Going analog is an interesting concept but it would be disqualified for two reasons. First would be that there has been no analog PC built [citation needed]. And second is the size. Both the Antikythera, and Harmonic Analyzer were considerable larger than the A+. To the people continuing to quibble ...

Re: Is the A+ the Smallest PC in the World?

Nope you are all wrong... Except maybe Texibunny.

I conceded to the discussion a little with "general purpose" computer, but my quest re...

All computers before 1960 would be disqualified because of their size, so discussing other qualifications is a waste of time...

Sorry again, Android anything is disqualified. While the format is far more open than iOS it is still limited by design. And again, while you may be able to plug in periferals such as a game controler, the architecture rally doesn't support the idea. A PC does not need to be a descendent of the firs...

Re: Help setting up a "Headless" A+ over wifi

Agreed. The A+ is not the place to start for a newbie. But the B/B+ would both have the problem I am describing. HDMI monitors are still relatively rare and fairly expensive compared to their VGA counter parts. You also have the issue that most TV's with HDMI inputs are either located in places wher...

Re: Help setting up a "Headless" A+ over wifi

Nice. So it seems like the USB-TTL cable is the way to go. I would still like to find a non-invasive solution for the PC. Something that would help out the newbie who got one as a stocking stuffer.

Re: Help setting up a "Headless" A+ over wifi

Both of those are entertaining, but while a virtual machine probably doesn't qualify as invasive, it is definitely akin to using a sledge hammer to drive in a finishing nail. The USB to TTL adaptor is a good second choice. It requires and extra piece of hardware, but it is a cheap on. The big questi...
