Pro tip for repairing things with #3dprinting: flatbed scanners! You probably still have one somewhere, they allow for precise measurements of complex geometries, and can usually fit larger objects than your printer. It often works even if the bottom surface isn't perfectly flat. Most of them shine light from the side, so rotating objects to get better contrast may help.

German Elections: Did the Eastern Bloc Vote Radically? Not Exactly

The German parliamentary elections were held on Sunday. At first glance, it may seem that former East Germany has become radicalized, but this is quite a distorted view.

CenterNegative is quite common on traditional Japanese Electronics.
The car makers in Japan just kept going with it for a few years after Ford&Crysler went to ChassisOnGround.

@scy @__michaelg I wonder why center-negative is so common in audio equipment, my guitar pedals all have center-negative...

@elly
"chassis-ground on plus" was the standard for cars, trucks and tractors in the US into the 1950ies, so did the (at that time) non-stereo-car-stereos ;-) which were tube radios.
Companies with "car radio" roots just reused their existing schematics/function blocks for guitar amplifiers.
And since "preserving/remodeling the good old xyz-sound" is a thing on guitar amps, keeping the legacy designs of the 1950ies alive as much as possible is a thing i can relate to.

@Peetz0r @__michaelg Are there still some of those around? Old Japanese electronics made in the 1980s sometimes had center negative. Are there modern laptops wired like that?
Show threadPeetz0rNov 1, 2024

@mike805 @__michaelg This is an HP Onmibook from 1996.

But I have an Casio keyboard (CTK-481) that has a center negative barrel jack.

And a Brother labelmaker from 2017 that also has a center negative barrel jack.

Show threadWyatt (🏳️‍⚧️♀?)Nov 1, 2024

@Peetz0r @__michaelg i just never take anything for granted and take things apart to probe known ground pins for continuity with the jack, but tbh your idea is better

also many old japanese things use that polarity; famicom, mega drive/genesis, master system, roland mt-32, roland sc-55, snes/super famicom
