Looks cool AF but a bit of an overkill.

I threw my Pi4 into a Pi3 case. Connected up a Pi-fan (5V 200mA). The Pi4 was idling at 37 degrees. Results from a stress test are below:

Code: 
pi@raspberrypi4:~ $ ./temp_test.sh
STARTING TEMP:  temp=37.0'C

ROUND 1 START TEMP : temp=37.0'C
ROUND 1 START THROTTLE INDICATOR : throttled=0x0

Time to complete stress test:
real    1m26.505s
user    5m45.860s
sys     0m0.021s
ROUND 1 END TEMP : temp=52.0'C
ROUND 1 END THROTTLE INDICATOR : throttled=0x0

ROUND 2 START TEMP : temp=52.0'C
ROUND 2 START THROTTLE INDICATOR : throttled=0x0

Time to complete stress test:

ROUND 3 START TEMP : temp=53.0'C

FINAL TEMP:  temp=54.0'C
 
Communica used to have an Pi 3 acrylic case with fan for R95.

I can't see why these need to be so expensive.
 
Are there any Pi projects that don't need rocket science to make work?

I tried a project that said it would control a camera and purchased the relevant camera from their list. It was a Canon IXUS

After several hours entering and checking the code I connected it to the camera via a USB cable. The camera switched on but the shutter remained closed. A programmer friend looked at it and spotted several errors in the supplied code that he fixed. This time, shutter opened once but not again

I'd also like a project where I don't have to buy expensive additional kit

So far I have got a media player to operate in that a Mac will send the audio to the Pi wirelessly and then the USB output will attach to a separate DAC

Thank you

There are, the key is to start with more basic things first and the to build up to the more ambitious ones.
I agree with you about the coding, some of the code the guys post make my atrocious code look good!:) And sometimes I wonder if their project ever worked at all.

Many of my projects have been made from stuff that broke that I dismantled, but when I decide to buy something I make sure to have 3 or more different tutorials using the same thing to have some options.
 
I have wasted another two days trying to get this device to do something other than boot up into a Linux-looking screen

One Australian fellow has a YouTube page where he says it will receive Netflix. All that happened to me was that I got a snotty email from Netflix saying I was logging on using an illegal device

So I will sell it

Pi 3B, acrylic case, 5V psu, 32Gb SD card and HDMI cable - is it worth R500?

What exactly is it that you are trying to achieve?

Id say depending on how old it is, thats a fair price if you dont need the updates from the Pi4.

I still have a Pi2 running 24/7, that is running Pihole (blocks adds and trackers), SAMBA with harddrives hooked up to share media accross my home network, script controlling a smart power switch hooked up to a wall panel heater in my babies room, and some other stuff. In its earlier life I had it working as a security camera running "motion".

Im really impressed that this thing is still running as its been going since I got it about 4 years ago or whenever the Pi2 was released.
 
The release of the RPi4 spurred me into action on a couple of projects (even though I only have a 3B+).

I built a football score monitoring website with a couple of goals
  • Build it in NodeJS with a MySQL backend
  • Clean functional front-end that can
    • On-board new players
    • Track goals and assists and tie them to a time and match
    • Display calculated historical stats
    • Sync goals in real time across devices using WebSockets
  • Containerise the project so it can be spun up on MacOS, x64 Linux and ARM
Here are some screenshots:

It's functional, I would like to add deeper analysis but at the moment I am happy with it.

I then also stumbled across https://parsecgaming.com which despite the fancy looking website is freeware that allows you to stream your screen from device to device with the RPi fully supported. They support both local and cloud streaming (I think they make revenue from renting cloud compute for gaming?) and setup is super simple. Install the package on the RPi, install the client on the PC, register and bang it's done, my RPi connected to my TV was suddenly mirroring my gaming PC. I hooked up my cloned Xbox receiver, the controller was recognised right away (which doesn't even happen natively on windows) and I could fire and Rocket League and start playing.
The latency seems perfect for controller based games (doubt you could play a twitch shooter as well as you can natively) and the stream quality is really good. If things get busy on the screen you can see some blurring but nothing terrible. So much better than my experiences with Steam In-Home streaming and not tied to hardware like nVidia's streaming tech. My devices are all connected to a 100Mbps switch so I can't talk to its wireless performance or whether 1Gbps would improve it even more (not that there is much further to go).
