Re: Powering Pi3 and HDD

Take a look inside a USB hub, it is not simply split wires. Do yourself a favor and buy an inexpensive, powered hub and additionally, a decent quality power supply with a high quality, short Micro USB B cable.

Re: Raspberry pi 3 running way too hot

Even outside a case, the Pi3b will easily shoot to ~70-80℃ if you use the internet on it.

I remedy the issue with a small heatsink and as extra measure, I added a fan that only turns on if the Pi hits ~65℃.
So far so good.

I wish people would just accept the fact the Pi gets hot under NORMAL use.

Gimp is even slow on a decent machine because it has become so bloated. It will be hard to run with such little available RAM.
Wait until you've installed dozens of plugins and the GAP plugin, GIMP will take close to 2 minutes just to start, and thats on a mid range desktop!

Re: I need help to run windows games on a PI.

You can run more than just retro games on a Pi, depending on what you want. Some pretty cool games can be made with PyGame and similar. A lot are crap or retro, but there are some good ones in there and yes, you can just "download and play" them. Now, to satiate my own entertainment from the misfort...

I think you missed the subtle sarcasm, directed at the Pi foundation. A glance at my signature may help you understand what I had meant.

More processing power is pointless in my opinion.
The Pi's bottleneck in crunching numbers is the RAM, which you aren't going to increase ever.

I've got a similar project. I ended up using two speakers nabbed from China courtesy of Ebay. They're a little more expensive than most but really worth the extra cost.

Re: [SOLVED] Pi Zero W - No overvoltage protection?

There've been a couple of people recently testing powering their Pi from a 3.7v lithium battery (with no boost circuit)
Apart from no USB and no HDMI, their Pis are working just fine, so undervoltage "protection" isn't even necessary until you hit ~3.4v

Easiest thing is to go to a discount store (e.g. "dollar" store) and get one of those little USB battery backup things. Use its USB output to help power the Pi. Use its charge input to keep it charged. It should have overcharge protection built in. Now, how to get it all hooked up, I'm not sure. Bu...

Re: RenPY on PI3

Sort of.

The Ren'Py launcher doesn't work properly yet but you can use it to work on your projects and also to run (built) projects
Unbuilt projects will work, but are unstable.

Re: Desktop too big - - spills of screen

The resolution is too small, you need something larger.

IIRC, you can increase the framebuffer size or whatever it is called, before it is drawn to the screen, but I have no idea how and I imagine it would impact performance.

Also the 'current the Pi demands' is between 350mA and 750mA for a Pi3b The 2.6A is recommended in case you plugged in some kind of USB device or other ...

Point 2) is valid as well. It's just that in my experience the micro-usb connector is the most unreliable part of the system. Not mechanically sound.
