Re: Connecting RockBand Drums to GPIO

Since a piezo transducer has high output impedance, I would make the chain like this: Piezo -> trimmer -> filter ->A/D -> Pi The piezo also has very high output voltage compared to any EMS noise you may encounter, so I wouldn't worry about driving cables as long as you have a high input impendance t...

Re: Connecting RockBand Drums to GPIO

The GPIO pins are for digital data only. Commercial drum trigger modules use an A/D converter to convert the trigger output into digital data that the processor can manipulate. If you think, "That sounds simple enough," read on. Low cost drum trigger modules multiplex several inputs into a single A/...

Re: ddclient - no dyndns provider

First off, what are you trying to accomplish? Are you at a remote location and need to connect to your Pi over the internet? If so, is your Pi always connected to your server through the LAN cable? If yes, then give the LAN connection a static address and your Pi will always be available at the same...

Re: [HOWTO] Rasberry Pi as a wired router with webmin as web

Dammit! The ARM drivers for my SMSC based adapter must be screwy. Your Apple adapter uses an ASIX chipset, but ASIX's drivers don't support 64-bit OSX (last I checked). My SMSC adapter works great in 64-bit OSX however, and I can transfer around 220Mbs on my Mac. I can only surmise that the drivers ...

Re: [HOWTO] Rasberry Pi as a wired router with webmin as web

Are you actually getting above 50Mbs duplex? I can get 100Mbs+ half duplex (from the Pi or to the Pi), but never above 50Mbs across the Pi (one external machine to another external machine, with the Pi as a simple router between them, using a USB gigabit ethernet adapter and the built-in ethernet po...
