Oh super, das isses!

Comodo komplett ausgeschaltet: 5 Sekunden
Comodo Firewall an, Defense+ an, Antivirus an: 60 Sekunden
Comodo Firewall an, Defense+ an, Antivirus aus: 10 Sekunden
Comodo Firewall an, Defense+ aus, Antivirus aus: 5 Sekunden

Wunderbar, jetzt ists noch schneller - Vielen Dank!!  smiley

Hallo ans Forum!

Bei mir gibts auch das Problem unter Windows XP: Kompilieren dauert ca. ne Minute, Upload geht dann fix. Habe bereits allerhand deinstalliert - ohne Wirkung.

Jetzt habe ich herausgefunden, dass beim Kompilieren ein Prozess namens "cmdagent" extrem aktiv ist. Sobald ich den einmal mit dem Task-Manager gekillt habe läuft das Kompilieren bis zum nächsten Neustart des PCs super flott in 10 Sekunden!  8-)

Beste Grüße

Thats it! Deactivating comodo results in a 5 second compilation instead of 60 - thats so nice smiley

Thank you very much!!

I've been facing slow (about 1 min) compilation too, having Windows XP and an Arduino Mega 2560.

In a german forum thread ( http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1285102917/27 ) someone uninstalled MS Visual Studio and other stuff - but this didn't work for me.

I've discovered that on compilation a task "cmdagent" is very heavily using my cpu. After i killed that task in task manager compilation still works but is fast as lightning!  8-)

So i have to kill this task when i first compile after rebooting my pc.

Greetings

Actually I dont know :-) ... I wrote it only for reference ... so far I've seen piezos comming in two flavors: some with 1.3kHz and others with 2.9 ... but dont ask me :-)

Teensy looks very intresting! Maybe I will use one of them for future projects. Thank you! Thats very good to know!

Hello David,

an hour ago i've tested my cheap and standard 2.9kHz piezo (which has the same size and looks a lot like yours on the images you posted) with my belt pressing it above my eyebrow. ... kind of Karate Kid ;-)

I used Processing with the sketch from the following tutorial to visualize my eyebrow movement as a first step: http://arduino.cc/en/Tutorial/Graph

The sensitivity was very good! Also slight movements has been triggered.

Hope this helps. Sammy.

Hey there,

just a question: do you think these cheap piezos for about $1 could do the trick? Or do you have any special needs in terms of size, sensitivity, etc.

I've been playing around with these for a week now. The easy setup (I didn't even thought about amplification) really impressed me: http://arduino.cc/en/Tutorial/Knock
