Retropie Briefcase
-
Hi,
I began making a briefcase project like I've seen around : a big LCD screen tightened in one part, and everything else nicely fit in the other part...I am using a 17" LCD screen, and as I unmounted it yesterday to only keep the necessary parts, I noticed that the outlet had a ground part, linked to the metallic bottom of the screen.
I now have this ground-cable unattached to anything, and wanted to ask you what are the risks of letting it like that. What should I do to make it safer ? If I attach the cable to the briefcase which is kind of metallic (aluminum), I am afraid I could get electrocuted while touching the case...Thanks in advance !

What was it originally attached to? Can you replicate that in your build?

The ground cable was originally attached to the metallic bottom part of the screen. The part that would reside on the desk, separated only by four cushions.
On each side of the bottom of the screen there was plastic parts so once the screen on the desk, it would be impossible to touch the metallic part.
If I try to replicate on my build, attaching the cable to the briefcase for instance, it would not be the same as it would be easy to touch the case...What I am thinking is to keep the metallic part of the original screen, and place it in the final build, behind the screen display but separated by something... I wanted to get rid of it to gain weight, but if I gain security it would not be that bad.
Heck, if I can remove the metallic part totally and not lose security, it would be best :-) -
@TheJuice Did the original screen have a power supply in the same case and the LCD? If so and you are keeping the original power for the screen, you should somehow encase that power supply in a metal box or maybe part of the original case. That could also block any RF that it generates from getting into your sound.

Indeed, the cable from the power outlet went to the original screen directly.
So using the original metallic part, or a metallic box as you say, I think I'll be safe.The RF part is important too, and I'm sure that if you didn't tell me that, and I had proceeded without enclosing the power supply, I would never have found why I'd have heard parasites in the sound :-p
Thanks !

@TheJuice Glad I could help. On a safety note, what I have done in a project like this is to get everything working before buttoning up the case and test it out. Plug it into a switchable power strip with it turned off, switch it on without touching anything on it. Then take a multimeter and ground one lead and touch any exposed metal to see if their is any voltage detected. Better to find out early than late!!
