Here is a quick update video to let the viewers know what is happening with the Bob-O-Vision project, formerly known as the Bob-O-Scope. During the process of bringing up the system and producing the video series, gremlins creep out of the woodwork. Labguy does his best to stomp them out as he goes. But, the little beggars can be tenacious. We take a look at the current head scratcher and a few images of the project progress thus far.

Enjoy!
Labguy out!

    It's impressive how much detail is shown in the video on such a tiny screen!

    Hey Rich, Been a while since I’ve communicated to you. Think the last email was like 2 years ago about a Sony HVM 100 unit. Was just wondering if you had anything like a AVC 3200 or any other tube cameras that you’re thinking of selling. Can’t seem to find any on the market so I’d figured I’d go ahead and reach out. Now I gotta say the craftsmen ship in this is absolutely fantastic from all the transistors to your board. Glad to see it ALIVE! Working on a project of my own as well involving a KY 1900. One of the tubes died and somehow I found a nos replacement so that’s currently on my plate. When is the next video coming out? Been a bit! Great video as always! Adam c.

    No need to buy a low value capacitor, make one! Two insulated wires can be twisted together and trimmed later for length. Allow about 25mm per pF. Sometimes called a "Gimmick" Capacitor according to Wikipedia.

    Dam Gizmo in the works ! Still looks good to me ,i am always confused as i thought its not possible to display this line rate without lines over lapping on a small crt like this but i see the image is pretty crisp ,I have plans on trying it on mine to see ,i was going up to 240 line but would be easy to try 525 or 626 line

    It's looks great. Maybe you will try to show on a bob o scope yourself with camera or something else

    “Parasitic” conductance and capacitance fixes the linearity?! Who could have guessed?

    Hey!! I'm about to buy a Sony AVC-3400 portapak and have a big question!! The seller sayd it powers on but when they press any of the buttons, the machine just makes a clicking sound.. Do you think that's because there is no tape in the machine??
