Nah I'm not running the pi anywhere near its limit at the moment. It's headless and averages about 8-10% CPU and a consistent 1GB RAM usage (out of 4). It's okay at the moment and runs on average around 54 degrees with a max spike of 62 rarely. But I'd rather keep my electronics cool if possible, es...

Hey, I'm not that familiar with the power side of things so just wanted to check if my understanding is okay here before jumping in... I currently have a Pi4 in a 3D printed enclosure along with a powered USB3 hub (with 2 HDDs connected). Everything is running fine from a power point of view given t...

Thanks for the replies! Strange as it seems, the easiest and most reliable is to use a power strip that splits a single mains socket to allow multiple plugs for separate power supplies to be used behind the scenes. Definitely the easiest but I've already got loads of extension leads! I'm trying to ...

Wondering if you ever found a solution to this instead of running both power lines? I decided to use a powered USB hard disk on one USB 3.0 port which lets me fit in the present current limit. I use the second portable hard disk as my off-site backup now. I got worried after reading about some USB ...

I've got a Raspberry Pi 4 powered via a Samsung S10 charger with a separate USB 3.0 powered hub that connects 3 usb HDDs to the Pi. All of that is working fine and I'm not getting any reports of under voltage via the red LED or from the results of "vcgencmd get_throttled". The only downside is I req...

Just logged on for the first time in ages to ask this exact same question, sorry I don't have an answer but I'll sit seeing if anyone has one! I was hoping 5V wall supply into hub, hub into Pi power input, Pi into hub data port and then two usb 3.0 drives into the hub. Ideally could do with someone ...

Thanks for the replies, sorry it's taken so long to respond! Is there an issue powering it directly from the pi's power pin? I believe my power source into the pi is strong enough to handle that. If not what would be my best bet at powering it? Also I don't suppose you know of any guides I can foll...

Looks good, £2.72 on ebay! Already got the cables to hook it up. Would I need an external power source to power this or would the pi be able to directly?

Hey, I need a setup that will allow me to create a horizontal push process with the raspberry pi. I've found the below which looks ideal for what I need although I'm not sure how I'd actually connect it to the pi. I've used stepper motors in the past but they've had 5 connection pins instead of 4 an...
