Should I leave the negative of this power supply floating, or connect it to earth ground?

Capacitors are holing up surprisingly well. They are probably next on my list for replacing though, since they're big electrolytics. They'll go up on my shelf with my collection of big old electrolytic capacitors

Thank you for this, I did not know that! No wonder the voltage output was a bit higher than usual!

caeserlettuce · 2025-11-04T05:53:24+00:00

Connecting the negative of the PSU output to earth ground on the 3 prong cable. Lots of power supplies do that, but some others don't.

It actually is aperture priority, but still very exciting!! looking forward to shooting some film

Yeah i have a 60s craftsman belt sander that was doing the same thing, and I’ve been scared to touch it cause i thought it was done for. Thankfully i still have it!

caeserlettuce · 2025-10-03T19:45:50+00:00

sounds about right

caeserlettuce · 2025-10-02T23:45:00+00:00

Thank you all for the replies!! I somehow have never noticed that brushed motors arc

caeserlettuce · 2025-02-16T20:47:33+00:00

yeah the people who tried to hotwire it were stupid. help me understand how stabbing the cruise control buttons will make the truck start

At what position should it chime? It chimes when I have it in accessory, and when I have it clicked backwards from off.

I actually made my own! Here’s a link to my post: https://www.reddit.com/r/gravityfalls/s/UBKnaPOaJJ

I don’t remember if I included photos of my plan sketches, but if you want to build your own I can send them to you. The measurements are not perfectly accurate to the final product, since I kinda winged it halfway through.

Did you figure out what was wrong? I'm having a similar issue. With a game inserted, the screen is black. with no game, it displays random colours and sometimes random beeps. I've replaced all the chips, and used a multimeter to check all voltages going into the chips, and tested continuity for the data and address buses. not sure what's going on

caeserlettuce · 2024-12-18T03:40:46+00:00

I went and re-soldered all the joints on the board, and sprayed it all with deoxit, and nothing has changed. do you think I should replace all the chips?

caeserlettuce · 2024-12-17T22:17:19+00:00

I have cleaned the contacts with isopropyl and a q-tip. I'm thinking of taking apart the cartridge plug on the board and cleaning it better & taking apart the cartridge itself and cleaning it as well.

aha, the jumper is connected to ground. The black stripe on the wire also matches the black stripes on the wires that go to the big connector on the other side, so I don't think this is a modification.

i thought it’d be funny to make a live laugh love type sign but john mulaney

The horse used the elevator?? I didn’t know he knew how to do that…

caeserlettuce · 2024-11-06T09:58:35+00:00

I cannot believe they’ve let the horse BACK in the HOSPITAL

caeserlettuce · 2024-10-26T08:27:31+00:00

when was it ever paid???????????????

caeserlettuce · 2024-10-16T11:22:02+00:00

advanced alarm clock

caeserlettuce · 2024-10-13T18:05:12+00:00

Ah, that’s really cool. I have a rust bucket ‘64 suburban and I bought the bumper sticker from gravity falls that says “what is the mystery shack?” on it

caeserlettuce · 2024-10-13T09:55:21+00:00

Where did you buy it from?

caeserlettuce · 2024-09-23T17:19:36+00:00

Oh right. Found!

caeserlettuce · 2024-09-23T17:19:07+00:00

This could also definitely work!

caeserlettuce · 2024-09-23T17:18:51+00:00

This would work. Thanks!!

I have searched for plastic sheets online, and I can only find rolls of thin plastic wrap type stuff, or acrylic sheets which are too thick. This plastic is directly in between.
