C-video to USB thingy

The software from Lumens that you use to control the DC160 — Version 1.1.2 from 2012 — does not install on Windows 10 (though I think it runs OK). You can make it work on Win 10 if you try hard enough.

I bought a very cheap RCA (C-Video) to USB adapter off ebay (“USB 2.0 video audio capture RCA adapter“), and wanted to see if that would work, to make it easier to use the camera on a wider variety of platforms.

Yes, is the answer, but not that well. DIP switch is the hint. On Windows 7 or 10:

  • Plugged in device into computer.
  • Windows installed some drivers.
  • Looked in device manager.
  • USB2.0 MIC appeared in Sound, video and game controllers.
  • Looked in Devices and Printers.
  • USB2.0 PC CAMERA appears — OK!
  • Set the DIP switches on the base of the DC160 to ON ON OFF ON (PAL, C-video, SXGA); switch 2 is the crucial one — if it is ON, the C-video works but the USB video that feeds the Ladibug software will not, so you cannot switch back and forth between the two without powering off the device and changing the dip switch.
  • Plugged the RCA cable into the DC160.
  • Turned on the DC160.
  • Put the miniCD that came with it into the drive; drive didn’t pick it up. Another computer did. Ran the FSC Player_en.exe file (runs in userspace, no need to install).

Onscreen Menu looks good, let’s me control the camera without a remote.

A bit pixelly. But very easy to use. It shows up as a camera in Zoom, Skype etc, so I can switch to it to show people what the camera can see.

But it works fine.

Webcam app

Logitech Capture (from the Logitech website — do not download from a third party site) — cannot see the camera. Other webcam software can, though (for example, Webcamoid).

See the manual Getting started with your Lumens document camera for the various DIP switch settings.

End result: Works better through the Ladibug software, but this kind of works. Not sure it is good enough to replace the Ladibug software.

OpenBSD on a Beetle

The Beetle is a low-spec machine. Very low. But OpenBSD works very well on it.

After the install comes customisation.

Key packages:

FLWM — the light but easy-to-use window manager

surf — the web browser that gives the modern web, JavaScript and all, without using all your memory (goodbye to Firefox, and I never said hello to Chrome)

bash — I have used it on Linux, and I just find bash easier

vim — my editor of choice

Ted — for that little bit of word processing

netsurf, links2 — for the web when I don’t need JavaScript

git — for the odd thing I want to install from source

mrxvt — my favourite terminal

alpine — for mail

All these except mrxvt can be installed using pkg_add. So I’ll just list the mrxvt prpocess:

  1. Download the source
  2. Extract it to a directory and go there
  3. ./configure --with-save-lines=65535 --disable-xrender --enable-xft
  4. doas make install
  5. In .profile, I just put alias mrxvt='mrxvt -sl 65535' to make it use all those saved scroll lines.

Done. Oh, and surf is really great. You don’t have to be an expert to use it. I just created a local page of very simple HTML with all my bookmarks on it, and then in .profile:

alias mysurf='surf /path/to/bookmarks.html'

So when I run mysurf, I get my page of links to choose from. It’s great. I have a Atom 230 chip and 512 MB RAM and I can edit a WordPress page and do all that stuff that really light browsers can’t do because they lack JavaScript. I mean, surf’s not fabulously responsive on a WordPress interface page, but it is quite usable.

Mercury (CCDC) on 64-bit Debian

Tried Mercury 3.6 on 32-bit Debian and the -mesa option got it to work. On 64-bit Debian (9.4), no such luck.

Eventually, tried the Windows version installed through wine. Note that I am running 64-bit Debian but wine is providing 32-bit Windows.

$ echo $WINEARCH
win32

$ wine mercurystandalone-3.6-windows-installer.exe

Nope.

ran winecfg; added the installer to the list of applications and set it to run as Windows 7.

Screenshot of the wine winecfg main window, showing the Mercury installer file added as an application.
winecfg main window

Then installer ran, but barfed.

Something about “ntlm_auth version”.

Search for “ntlm_auth” at https://www.debian.org/distrib/packages. Is it even installed? Well, can make sure easily enough.

sudo apt-get install winbind libnss-winbind libpam-winbind

Tried again with wine set to mimic (“wine is not an emulator”) Windows 10. Nope. OK, Win 7.

ntlm_auth error was now gone but got another complaint.

Screen shot of the error box. It says The visual C redistributable package failed to install. Software may not work. You should run C:\Program Files\CCDC\Mercury 3.6\vcredist_x86_2010.exe as administrator once installation is finished.
Error message on installing Mercury. Install finished after clicking OK and is seems to work…

But Mercury did launch. Guess I’ll use it till I have a problem …

Screen shot showing Meruryworking. Seems OK as far as I can tell.
