      It kills me to see you hacking the paper with that blunt object you call a knife. PLEASE! Take a lesson from Mic Dundee and get a “real knife.” :)

      I’ve got to stop following your twitter feed. It’s like reading the spoliers before watching the movie. :-)

      Switched off the local analogue TV TX. The very same TX which is sitting behind you on the shelf! Time to dig it out and fire her up…

        That’s just an exciter, not a full transmitter…

          300W of Exciter. Even if it was 300mw it would transmit across the lab on the lab on a dummy load.

      That robot arm might be very nice for pick and placing large items like CD/DVDs for a home made disc duplicator or backup system.

        If it can lift beer cans and scratch my cat’s back then I want one!:)

      Dave – regarding backlighting the sign – I see some good ideas on the forum, like an LCD diffuser or lighting from the side.

      I also came across something the other day that I’ve been wanting to try. They make some sort of etching cream to add a frosted effect to glass. Not sure if it would work for other materials, but it’s worth a shot. If it does, it could give you a nice even lighting effect. Available at hobby/craft type stores, Walmart, etc.

      I saw it mentioned here: http://www.eetimes.com/author.asp?section_id=36&doc_id=1320712

        I’ve tried a diffuser and it’s still quite poor.

      Dave, are you using your new mic? The audio on this video sure sounds much more crisp than it usually does. The things you notice with studio monitors! :)

      For back-lighting the sign, have you considered using EL panels? They’re evenly lit across their surface, and you can get them in quite a few colours.

      Brilliant arm, but it’s open source so is there any where I can download the plans and programming code?

      When is the robotic arm vid coming?

      No word on where to get those cool lab notebooks? I’d love to have one of those Amp Hour notebooks with my name on the spine!
