@sstallion Hi! Yes, the PowerBlock does some software debouncing. Please contact me at contact (at) petrockblock.com and I can send you a firmer with the momentary button support disabled. I have this, in fact, already prepared.

@StuMcBill Glad to hear!

@Retro-Arcade-Fan The shops listed on the pi website are approved resellers and are reliable. I would then compare them to see which ones charge less shipping.

@lister-of-smeg said in Red Light Power Flickering:

I would start by checking the rest of the peripherals (you mentioned having another pi - use that with the exact existing setup) That should let you know if the original board is faulty or not

If the board is randomly shutting down I suspect it will need replacing

Alright, I'll try that later today. Yeah I also figured it needed replacing.

Just thinking of how to prevent a repeat, could a split-second power outage have caused the Pi to die? While I was playing on it weeks ago, there was a quick power outage a week ago during a thunderstorm, not long enough for the PI to lose power or immediately cause this problem, but maybe that could have fried the electronics? Maybe I need to use a UPS or regulator

@mitu Oh, gotcha. I'll try that out.

Can you post the info requested here? It will help to troubleshoot your issue. https://retropie.org.uk/forum/topic/3/read-this-first

Also may want to take a look at this post. Specifically the pi 4 section.

So, I have mounted the PowerBlock and I have tested it for some days. It works almost as expected, spordically it shows unexpected behaviour. I will create a separate thread explaining my observations.

Anyway, thanks for supplying me with a replacement device.

none of the above. I think? I might have changed some settings that were suggested in the github article about reducing input lag, but AFAIK I only did that in the NES core

@urko948 Use the official Raspberry Pi power adapter or whatever the Raspberry guys recommend.

I had this problem on an old atari, I think i needed to drop from 12v to 9v, I just bunged enough diodes in series to get a big enough voltage drop, worked well.

However, that doesnt take into account the prviously mentioned issue of if the voltage is ac or dc and if the amperage is enough, which it almost certainly is not.

@jonnykesh you are right. I am an idiot. And i set that every time i set up a pi so i should have remembered that.

@sgtjimmyrustles
Already have a backup that I update regularly and it seems to be the best thing to do.

In case sd gets corrupted, just write the image and done..

Or get the proper raspberry pi power supply

Could someone suggest to me a plug that is 5.1v and at least 3a?
I am having a hard time finding one that is good enough.
