Re: That PI2 unboxing: Unmistakable Odor of fried circuitry?

I just received two new RPi 2B boards. Yes they smelled like they were burnt. But both worked just fine.

All of the latest RasPi boards seem to have this burnt smell.

Basically they just do not get much time between production to boxing them up. The smell just does not have time to go away I guess.

Re: PRICE CUT! RASPBERRY PI MODEL B+ NOW ONLY $25

No the CHIP price does not include tax or shipping. Or the $20 extra shipping to send it out of the U.S., according to their kicksatrter page. I am glad someone in the U.S is getting into the game! I wonder if they, or their sellers, will hold the price point after it goes on the market. The Foundat...

Re: Cnet is Creating False Information about the Raspberry P

Earl Grey hot; 2 3/4 hours to print the cup. Then the tea will probably be cold. LOL. One point this discussion has missed, is that a whole lot of the projects people do on RasPii are headless. This means a video board is not really necessary. Composite out for initial setup is more than adequate fo...

Re: I`m watching a Pi powering via USB, not Micro USB.

Back-powering on RasPii has been working since the early boards (B and A) it ended with the B+. The A+ back-powers just fine. I have tested it on an A+, no problem. Back-powering is no more, or just as dangerous as powering by GPIO. It just depends on the quality of the power. What should not be don...

Octopi with Cura plugin on Pi2

I just finished getting OctoPrint (Octopi is the Raspberry Pi version) with the CuraEngine working on a Raspberry Pi2b. This is not a full version of Cura, just the engine. This allows you to drag and drop .stl files directly onto the Octopi webpage and have them "sliced", automatically rather than ...

Re: Stable power from car battery on ignition

Yes there are 12V UPS available!
Check out some at Mini-box. They specialize in car based computer systems. I am sure there are other places also.

Edit: many of those boards allow a 5V setting so no power adapter would be needed.

Re: Will there be a Raspberry Pi 2 B+?

I think the one thing that has been missed in the "PI" series is a keyboard. A version embedded in a keyboard would bring the Raspbery Pi back to its roots, the BBC micro. It seems like it should not be too hard to work with the foundations partners to get a embedded keyboard version out! maplin.co...

Re: Future PI hardware request: USB port

On a B+ you could remove one of the two USB connectors. Then you can solder in your own pin headers. I have modified a couple of B's to have header pins before. You chop up the USB with a set of side cutters, then de-solder what is left. I used 1/10" header pins. You have to work them in and they wi...

Look on Hobby King for your Speed Controllers and motors. They also have frames. Many of the motors will tell you their potential thrust.

If it has Apache2 installed the web page is needs to go into /var/www. There should be an index page there already.

We need to know if it is a default Raspbian install or not. We need to know what is installed for your web service.

The belts typically used on the 3D printers are "GT2" toothed belts. Usually 6mm to 7mm wide. You can find them on Amazon with the appropriate drive gear included. Mostly they use a stepper with a 5mm shaft.
