My comment is that I have both -- the Canon VIXIA HF-G40 (brand new as it was only released 1-FEB-2016) and a Manfrotto tripod which is 10-15 years old now. I'll agree, 1080p does look incredible.

recording video and audio at VCF East
by Steven Michelsen 12 Apr '16

12 Apr '16

If the room you are video-recording in is using a mic and speakers, the audio should be OK. It won't sound like CNN but should be legible, like this one from last year... https://www.youtube.com/watch?v=sidooQfvH4I Introduction: I'm Steven Michelsen. I signed up to this list yesterday. I have been a freelancer in the A/V business for 35 years. I programmed multi-image slide shows for corporate meetings and such, back in the '80s on an "AVL Genesis" - either as a branded PC, or with a "Genesis card" in an 8-bit slot in an IBM, Compaq or clone. Now I do powerpoint for a living. Same show, different technology. In recent years I have had a fit of nostalgia for the business as it was back in the day, and of course the gear that I worked with. I am now surrounded by IBM 5155s, Compaq portables, and some AVL branded computers, all in various states of repair. Not to mention slide projectors, dissolve units, etc, etc. Here's my AVL page: www.stevenmichelsen.com/AVL Anyway, all this talk tempts me to bring along my video camera and tripod on Friday (I live in northern NJ). Afterwards I can hand over any video files via dropbox or whatever you like. Steve --------------------------------------------------------------------------- You're both right, but we are dealing with very limited resources here. Let's please NOT make this another "You guys should..." thread. We are all doing our best. It is an amateur event and that's fine.

Final class schedule for this Friday

It's certainly reasonable to ask presenters to post their abstracts, some may have done so already. Brian L. Stuart said: > My early class is Analog Computer Basics.

By age I'm the last of the engineers who might have even SEEN analog computers in use. I operated one and saw another in use to model a chemical plant. These are a different world of computation from digital logic. I suggest anyone interested in this talk, do a quick read about "differential equations" first. That's the equivalent of telling someone "learn Boolean logic before looking at TTL circuits". If that's too abstract, look up how a pendulum works, a bouncing ball, stuff like that are all differential equations at work. Herb change is good -- Herbert R.

On Tue, 4/12/16, Brian Schenkenberger via vcf-midatlantic <vcf-midatlantic(a)lists.vintagecomputerfederation.org> wrote: > Are there any abstracts available for these classes? I feel like I'm pulling an AOL "me too" with Ian, especially since his line about being abstract applies very well to me too. My early class is Analog Computer Basics. I plan to go though the basic idea of electronic computing without bits. The first few minutes will be a quick overview of key ideas in electrical engineering. The second segment will look at using operational amplifiers to create mathematical building blocks. The remainder of the presentation will go through an example of modeling a simple physical system and illustrating it on a Comdyna GP-6. The second session I'm part of is on the ENIAC. Evan and I are basically tag-teaming about the ENIAC. I'll let Evan speak to anything he wants to say about his part of the presentation. My part will focus on the technical details of how the machine worked. I'll also be talking some about how it was programmed (primarily in its original mode of operation, but as time permits I do plan to talk a little about the instruction set architecture implemented in 1948). Several aspects of the machine's operation will be illustrated with an ENIAC simulator I've been developing over the past few months. I'll also echo Ian's offter that I'll be glad to adjust the focus and emphasis of my talks to address things that are of most interest to the audience. Hope that's helpful to anyone trying to decide which sessions to attend. BLS

If memory serves, the Cromemco Cyclops camera used an uncovered DRAM for the optical sensor. If so, that would be the most interesting construction feature of this facsimile version. Herb Johnson -- Herbert R. Johnson, New Jersey USA http://www.retrotechnology.com OR .net
