@RyanT besides the fact that we dont support 3rd-Party-Images as mitu mentioned: imo your advise is a bit of asking a crystal ball. If his Pi only shows the bolt with this new "prebuiltimagefromdahood" - and not with others...i guess it contains overclocking parameters by default. Without knowing the exact configuration it is impossible to recommend a specific PSU. Maybe the Image was meant for a watercooled Raspberry Pi with a 600Watt PSU - who knows?

@thestarglider said in SNES controller ghosting on Retropie/Kodi etc... An interesting find...: It would be interesting to know if anyone else had tried an alternative power source to their Pi when they've had issues with ghosting, because in all the threads I have read, I don't remember anyone else bringing it up. i kinda did :) https://retropie.org.uk/forum/topic/8187/gamepads-making-involuntary-movements-in-emulation-station the issue is power interference so it figures that changes to power supply or connection can influence it. however it won't fix it for everyone.

@emclinux thankyou I will give that a try tonight

Final Update: Turns out it was my charger all along . Here is what I ended up doing. From my Pi3 I run a DC Barrel Jack to Micro-USB B Male Connector (http://a.co/d/4yVdU3c) . Then from the barrel jack I have a normal power supply (http://a.co/d/7j0vMr3) . No voltage issues at all and everything seems fine.

@crazydude2 Yes, that would definitely cut the cost. I hadn't thought of doing it that way. But, then again, that's the point of being on this forum - getting other people's ideas as well as your own. Thanks

I'm using a Pac-Drive from Ultimarc for my LED buttons. @savetheclocktowr made a controller software for some nice sequencing effects. It's not needed for permanent lighting, the Pac-Drive will do that out-of-the-box in Retropie.

ok.. i was mainly curious if this was a standard, or decent way of doing things or not... seems a little wonky, but also works. since I do clear cabinets, it can all be seen :)

@suleske I found several inexpensive and simple circuits I could build. This little board has some added features (e.g. setting the key press switch delay), so I bought it: https://www.ebay.com/itm/262199569276

I suggest that you buy the raspberrypi charger wire as you will have no problem here is the one I have https://www.aliexpress.com/item/Raspberry-Pi-3-Model-B-5V-3A-Power-Adapter-Micro-USB-Port-Power-Charger-EU-US/32761294031.html?src=google&albslr=220568862&isdl=y&aff_short_key=UneMJZVf&source={ifdyn:dyn}{ifpla:pla}{ifdbm:DBM&albch=DID}&src=google&albch=shopping&acnt=494-037-6276&isdl=y&albcp=756822904&albag=35305934810&slnk=&trgt=68416666751&plac=&crea=en32761294031&netw=g&device=c&mtctp=&gclid=EAIaIQobChMIw_TNlLew1wIVmTUrCh0bLgcOEAQYBCABEgLoD_D_BwE

I also use the PowerBlock and it is well supported here. The guy who runs the place is a Global Moderator in this forum. Check the unit here: https://blog.petrockblock.com/powerblock/

So, the power source is really such an important point that in no case should not be neglected? And let's say if I want to use an external HD that does not have its own power, then it is desirable to buy a USB hub with its own power supply? But even so, I still can not understand what would be so terrible if the external HD is powered by the pi itself.

@Darksavior said in [Hardware] Power Help: Not sure what made you think it was Uk exclusive. I just assumed, given that the Raspberry Pi is made in the UK, so the power supply would be too. I ordered a powered USB hub from them for my Nintendo build, and it was UK exclusive. No biggie, thanks for letting me know! @TMNTturtlguy said in [Hardware] Power Help: @hansolo77 you mentioned microcenter before. Get the microcenter brand QVS 2. 5Amp micro USB. They have it with the pi3 stuff and it is made exclusively for raspberry pi 2 & 3. It costs $10.99 US. I have 3 of them on 3 units and have never had a problem. I've seen those QVS brand products. I've always been kinda shy to buy stuff like that. Sure, generic food and drugs is ok.. but when it comes to electronics I prefer to stick with a higher class brand. That said, I never even heard of this "iEssentials" brand before. But I saw it was cheaper than the QVS and just went with that. I suppose you do get what you pay for. I sort of impulse bought the 2nd one, because I couldn't remember if it was THIS one I had trouble with, or if it was the one inside the MCM Media Center kit (CanaKIT branded). It's good to know that the QVS brand is decent quality. Might consider that for my next project (whatever that will be lol).

@mena Please don't hijack the original post. But to answer your question, most likely it will also protect the USB devices connected to it from power surges. These USB ports are meant to power or charge devices only and does not have data communication capabilities. USB devices such as USB keyboard/mouse, USB game controllers, etc will require both power and data and therefore have to be connected to the RPI USB ports and draw power from it as well. @jay81uk simonster is right about the power requirements of various RPi models. So what is yours? The Kindle Fire power supply normally will provide 1A current which 150ma more than the one from chromecast.

@lostless aha, ok then.

@petrockblog Sorry, forum rules prohibit that. Just do a simple google search for them and options come up. I do love your ControlBlock though, thanks for making it!
