<body class='hmmessage'><div dir='ltr'><font style="" face="Tahoma,sans-serif" color="#000000">I realize it is a fun project to play with software and hardware but is it really worth all this effort to just turn a fan off and on? I run muffin fans on all my nodes but they stay on all the time. With some I have reduced the speed with a resistor - 10-50 ohm 1/2w. <br><br>Is the object here to save energy? Extend fan life? Why not just leave it run all the time? If you really want to protect from heat you would use a thermostat attached to the heat sink. A timed fan really has no idea what the temperature really is and so many other things enter into the equation like ambient temperature. Many transceivers get hot even sitting in receive in high ambient temperatures. <br><br>If you have something better to do (and I do) save yourself the trouble and just leave the fan run. DC muffin fans draw very little current and last a very long time.<br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">Date: Tue, 30 Aug 2016 18:28:59 +0000<br>To: arm-allstar@hamvoip.org<br>Subject: Re: [arm-allstar] Fan Control Using URI (or RIM) I/O<br>From: arm-allstar@hamvoip.org<br>CC: n7jys@yahoo.com<br><br><div style="color:#000;background-color:#fff;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173"><span id="ecxyui_3_16_0_ym19_1_1472579863420_4310">After following all the instructions I find this script does not start on a keyup.</span></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173"><span><br></span></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">In doing some hacking on the app_rpt_fan.sh I can make it work by replacing</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">PTTSTATE="/tmp/RPT_TXKEYED$1" with</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">PTTSTATE="/tmpRPT_TXKEHED42285" (42285 my node) and</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">FANON="/usr/bin/asterisk -rx \"rpt fun $1 *880\"" with</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">FANON="/usr/bin/asterisk -rx \"rpt fun 42285 *880\"" and<br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">FANOFF="/usr/bin/asterisk -rx \"rpt fun $1 *881\"" with<br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">FANOFF="/usr/bin/asterisk -rx \"rpt fun 42285 *881\"" <br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">The file that get's written and removed from the tmp directory is</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"> [events 42285]</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">touch /tmp/RPT_KEYED42285 = s|t|RPT_TXKEYED</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">rm -f /tmp/RPT_KEYED42285 = s|f|RPT_TXKEYED</div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr"><br></div><div id="ecxyui_3_16_0_ym19_1_1472579863420_4173" dir="ltr">work fine.

So I downloaded the latinovoip distro maintained by KP4TR, unzipped it, loaded it on a fresh micro SSD card, and booted it. I then went looking for the /etc/asterisk/local folder... but it does not exist in that version, either.
