Re: [sudo-discuss] giant laser for the robot

i was planning to just make an opaque, hinged privacy temporary-wall for when the robot is doing something dirty like that. It will help with ventilation too, which is a bigger problem than arc flash with the plasma cutter. but a plasma cutter is such an awesome tool, i think it's totally worth the annoyance of having to make it safe for puny humans. -jake On Thu, 19 May 2016, Adam Munich wrote: > You wont find an NIR blocking plastic curtain, unless it's black vinyl. > > - - - - Begin automatically generated footer - - - - > > Weblog: http://adammunich.com > Cell: +1-650-452-0554, M-F 10a - 8p PST > > PGP Public Key: https://pgp.mit.edu/pks/lookup?search=adam+munich > > > On Wed, May 18, 2016 at 11:41 PM, Patrik D'haeseleer <patrikd(a)gmail.com> > wrote: >> >> >> Cool!
