Just a reminder, using this kind of equipment in the US does require a license from the FCC! It is a radio transmitter and as such it does require compliance with the rules. Had a furniture factory that used RF heating for setting glue, worked great, BTW, but there it was, an FCC station license right on the side of the power supply.

Installing libncurses5-dev may help in this case. BTW: with the "deb-pkg" make target (instead of make; make modules_install; make install) one can create a handy Debian kernel package that can easily be installed with "dpkg --install linux-image-*" or removed later on with apt-get. $ fakeroot make deb-pkg You can also add a your own version string to the kernel image/package with e.g. 'KDEB_PKGVERSION="3.18" EXTRAVERSION=".9-rt4"' to differentiate it from other installed kernels of the same release version (3.18 in this case).

This seems to be a good idea especially if you config many machines. Let me first get the thing going and then I will look at making a package.

This page is very interesting and informative: http://www.richieburnett.co.uk/indheat.html I think that somewhere I found a full schematic for a circuit that handles the sequencing etc, but I rather suspect that the way to do it now would be with an Arduino or other simple-to-program microprocessor. I have started to find that nearly any electrical circuit can most easily be realised with a ?7 Arduino Nano rather than matrix board and components. I got as far as buying most of the components, and also have a suitable frequency generator chip. But then something more interesting came along. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------ Message: 5 Date: Thu, 12 Mar 2015 07:46:13 -0400 From: Mark Wendt <wendt.m...@gmail.com> Subject: Re: [Emc-users] OT: Allen Bradley PowerFlex 40 question To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Message-ID: <CABWWDmrg3ua37yPBxXp793b3yqo2wSnD=ykfkux1xyt4hhp...@mail.gmail.com> Content-Type: text/plain; charset=UTF-8 On Thu, Mar 12, 2015 at 6:27 AM, andy pugh <bodge...@gmail.com> wrote: <snippage> > > I got as far as buying most of the components, and also have a > suitable frequency generator chip.
