Re: RPi as configurable touchpad

Reaper not only has a built-in webserver for what you'd like to do, but also runs on the RPi.

Re: PIXEL FOR PC AND MAC

From the viewpoint of someone who has been running LXDE / Debian (lubuntu as well as Debian's own spin) on old iron for years, my initial reaction to the Pixel for PC announcement was "Does the world really need yet another Linux distribution?". My more positive second reaction was that more FOSS i...

Re: Gradiometer for archaeology

I've had a look, but the part that's missing escapes me. The company clearly wants to sell pre-programmed pics as there's no info apart from basic sensor info. Given you have two pulse outputs (from 2 sensors, or from one double sensor like the PGM-2, 0 to 20 KHz)), the necessary calculations are mi...

Ik snap het inderdaad niet. Waarom zou je zender én ontvanger van een draadloze afstandsbediening op één RPi aansluiten?

Dat klinkt niet "compatibel" met het idee "draadloze afstandsbediening".

Misschien heb ik gewoon wat meer uitleg nodig wat je precies probeert te doen :D

Re: Resistance on motor Raspberry pi

If you don't want to do PWM, just put three or four diodes in series with the motor. They'll drop 0,7 V each and combined with the drop from the transistors in the L293 it'll be OK. Using diodes to drop voltage has exactly the same issue as using resistors -- you are wasting a lot of power, which g...

Intel is a monopolist. No trick is too dirty, but they are balancing because they need to keep AMD alive or face legal problems.

Re: Resistance on motor Raspberry pi

Don't worry. A 3V DC motor will run fine on 6V if you use the L293 for what it's supposed to do: PWM. Don't go over 60% duty cycle or so. That's probably easier to do than build a reliable drop down regulator. The back-emf from the motor might just destabilize the regulator, unless you're careful. I...

Re: Mac OSX

FWIW: XNU, the underlying kernel for Darwin, the open source OSX-without-a-gui, is available for ARM.

It's ARM V6, so presumably, it wouldn't work for the Raspberry 2. And there are a lot of missing pieces, so it would be a gigantic undertaking, imho.

Re: Which Motor do I want for autostop?

Some car window motors have a current sensing stop mechanism, for obvious reasons.

Another avenue is a friction coupling, but these are harder to find and usually a lot more expensive. And the cheaper ones tend to slip after some wear.
