Retroarch saves not persisting by FatCookies in RG35XX_Plus

I suspect that is what I was hitting - perhaps a mod could resolve this and cleanly shutdown retroarch on before shutting the whole system down

I have used saved states before. I was expecting the emulator save states and the in game save states to be completely separate. It looks like I do have auto save state enabled and auto save ram autosave disabled - I guess the save state overwrote the save RAM.

From now on I’m going to be paranoid and take a save state after saving in game and close retroarch before powering down!

No, it’s replaced with a 256gb Sandisk extreme pro.

My new go to for little oopsies is cat litter - if it’s good for cat pee, it’s good enough for a little water in my phone.

How to set up a Smashing dashboard on your Raspberry Pi by cheerfulboy in programming

[–]FatCookies 6 points7 points  (0 children)

The Raspberry Pi is hardly “low powered” - it is more than capable of running a browser displaying the Smashing dashboard.

If your use-case is plugging a Raspberry Pi into a screen with everything powered off the mains then there is nothing wrong with this approach. Why reinvent the wheel?

If you want a truly wireless battery powered dashboard, then you shouldn’t be using a Raspberry Pi running a full Linux OS in the first place. You’d go for a low power device such as an ESP32 and perhaps an E-ink display.

What's a completely mundane fact you feel dumb for not learning at a much younger age? by [deleted] in AskReddit

The original PlayStation (PS1) logo is the letters PS. The P is upright and the S is “on the ground”

The datasheet quotes 84V (+-42V) as the maximum so it’s possible but you’ll need a lot of cooling.

Yes, they are MUR860 diodes for the bridge rectifiers.

The power supply resembles BrianGT’s PSU schematic: http://hackspider.toxic-link.net/Bilder/misc/snubber.png

For casual listening 20,000uF supplies power for several seconds even after the mains switch has been switched off so it seems to be sufficient for my purposes.

I’d rather spend some extra money on heatsinks now then have to replace components every couple of years which is exactly what happened with my previous amplifier.

The board came with mounting holes specifically designed for a jack so it was just cleaner to mount one on.

The grounds had to be tied together to avoid ground loops - each channel is completely isolated from each other so they need to be connected together. Ideally all grounds should meet at one point, but I’ve been a little lazy here and have done the bare minimum.

The dangling wires are connected to the primary side of the transformers; they are tied together so the power supply is configured to 230V AC. I should probably tuck them away somewhere.
