All eight units are part of a cell computer. I am modifying the entire set up to use POE ethernet. Extra Fans are being used and a mix of the heat sinks are placed an every chip I can see. Kubernetes and more will complete the software needs. A POE Hub will provide all power and I have a Raspberry Pi CM4 computer for a head unit. The 'Eightcell' will be headless. I am still collecting the components to complete the build because the POE Hats are making for minor problems, but I am over coming these problems. I plan on using VPN and extra security to finally and completely secure my home network. I included a picture of a single cell.

Hi PiHut.As a prolific user of the Raspberry Pi, you would probably like to know how I use your products. I am a licenced Amateur Radio operator, commonly known as a Radio Ham for want of a better word.For the past several years, I have replaced the old solid state logic used to control FM Radio Repeater systems with a Raspberry Pi, running Raspberry OS in its various forms, with a software called SVXLink (svxlink.org) running under C++ and TCL and a couple of other packages.By the use of a small USB Sound Card and a control interface connected to the GPIO, the Radio repeater has enhanced functionality, with the added bonus that it can be adjusted remotely subject to internet connection.Currently I have 5 of these configured, but the Radio amateur Community ... MoreHi PiHut.As a prolific user of the Raspberry Pi, you would probably like to know how I use your products.

I have several of these devices, three in RF Radio Repeaters, and two running localised HotSpots.In total I have currently in service three Raspberry Pi 2B, two Raspberry Pi B+, A Raspberry Pi 3B, A Raspberry Pi 3A+ and with the latest arrival of the 4B it is proving to be a very interesting time.I am currently trying to amalgamate the two aspects FM and Digital radio using SVXlink, and Python using stacked Raspberry Pis rather than introduce an X86 Server. What better way than the Raspberry Pi 4.Many regardsChris Jackson (call signs F5VMR and G4NAB)

It's a Pi. It's small, about the size of a credit card. It has a few USB ports, a bit of RAM, a processor, and some GPIO pins. It's the loosest definition of a computer in this day and age, it's used for a million different hobbyist projects, and it's nearly impossible to find. There's a whole website dedicated to pinging the inventories of known Pi sellers and displaying who has them in stock and for how much, and ThePiHut was one of the few stores not charging an arm and a leg over MSRP (or massive shipping and handling fees to send this little hunk of silicon and conductive tracing across the pond to the US).Thanks for helping me advance my hobby, PiHut. Much appreciated.

So... I order on 5/31 and just received it on 6/21. About 3 weeks but hey...that's ok. Just happy to find a Pi so I can keep my projects moving forward. Espcially since my Ninja buddy, Haley, had to help me out so I could order it. :-) She rocks!What else can you say about the Pi? Awesome devices that have me hooked like a methhead LOL. Got into them last December and I think this was my 14th one! Yup... Lots of projects. Octoprint, Open Media Vault, VPN, Security cams (Zero 2W), robotic vehicles just to name a few. Would be nice to be able to order from the US but, happy our UK cousins can accomidate. Cheers!
It is what it is, I was lacking a bit of power though, I hope they soon make a new one with a better cpu-gpu. I bought it cause I am studying a degree in computer science and thought that it will come handy for OS and network classes and well, all sort of subjects. I have them in next term so...Anyway, it is not capable of 4k fluid video streaming, so if your buying it with that in mind just get something more dedicated like a chromecast.I tried to use it with a 4k monitor and it struggles so have that also in mind. If you want to put a server or something like that the 4k dual monitor display can be handy otherwise it just lacks power but is also expectable.My recommendation, if you like to make things and experiment this COULD be for you, if you want them for ... MoreIt is what it is, I was lacking a bit of power though, I hope they soon make a new one with a better cpu-gpu.

Don't waste loads on it like the most expensive cases, it is pointless, same with the 8gb version, just not with this cpu-gpu, if you are going to use it like an emulator machine there is absolutely no emulator that would use that sort of RAM.And I doubt that if you are looking at this comments you will need it at all.
I bought the Raspberry Pi 4 Model B 4GB to replace my old Steam Link hardware as it wasn't capable of streaming 2160p. I nearly have 2160p 30Hz being streamed perfectly. I just have a couple of niggles I can hopefully work out. I'd much prefer 60Hz if I can get it there.It streams 1080p great but I had the Steam Link hardware for that already.I couldn't get the Pi to run Raspberry OS at 4K 60Hz. I enabled the option in the Pi Config tool and rebooted but it doesn't get past the debug colour wheel on boot. This might be a power issue though as I didn't buy the official cable. I don't have many other USB-C cables to try. I may purchase one at some point but the price is a little steep for me right now.A point for Pi Hut to note is that my letter box is vertical ... MoreI bought the Raspberry Pi 4 Model B 4GB to replace my old Steam Link hardware as it wasn't capable of streaming 2160p.

I may purchase one at some point but the price is a little steep for me right now.A point for Pi Hut to note is that my letter box is vertical and near enough eye level. I was near the door when the postie decided to drop it through. My heart sank as I knew that was going to be my Pi on the floor. Please can you post in something that won't fit through a letter box or at least put fragile on the box. I have no idea if that incident has impacted the life of my Pi. No immediate damage but who knows what that drop has done. If only he'd knocked. :(
Works fine out of the box. It's not as nippy as the 8GB version, which I also have. Slowish if used for Web surfing, but you get what you pay for. However it works just as well as the 8GB version when used with my Picotech Dr Daq and 1020 series ADC data logging systems and handles the real time graphing and computational tasks well. Buying it has released my 8GB version for more interesting projects. It did have one advantage for me over the 8GB version in that it gave me the opportunity to install the earlier Aduino IDE version 1.8 which has the Serial plotter option. The version 2.0 IDE which I have on my 8GB pi doesn't yet have the plotter option which is a serious omission if you want to plot real time data. If you just want the 4GB version for project work it ... MoreWorks fine out of the box. It's not as nippy as the 8GB version, which I also have.

Review of Raspberry Pi 4B: Disappointing Performance and Lack of Functionality I recently purchased a Raspberry Pi 4B with high hopes of its impressive capabilities, only to be sorely disappointed. Upon receiving the device and plugging it in, I quickly discovered that none of the LEDs or functions were working. As a result, I am left with no other option but to request a refund. First and foremost, the lack of any functioning LEDs is a major concern. These indicators are crucial for identifying whether the Raspberry Pi is powered on and functioning correctly. Without them, it becomes challenging to troubleshoot any potential issues or determine if the device is indeed receiving power. This absence of basic functionality is highly frustrating and casts a shadow over ... MoreReview of Raspberry Pi 4B: Disappointing Performance and Lack of Functionality I recently purchased a Raspberry Pi 4B with high hopes of its impressive capabilities, only to be sorely disappointed. Upon receiving the device and plugging it in, I quickly discovered that none of the LEDs or functions were working. As a result, I am left with no other option but to request a refund. First and foremost, the lack of any functioning LEDs is a major concern. These indicators are crucial for identifying whether the Raspberry Pi is powered on and functioning correctly. Without them, it becomes challenging to troubleshoot any potential issues or determine if the device is indeed receiving power. This absence of basic functionality is highly frustrating and casts a shadow over the overall quality of the product. Furthermore, the fact that none of the Raspberry Pi's functions are operational is incredibly disappointing. The Raspberry Pi 4B is renowned for its versatility and wide range of applications, but my unit failed to deliver on its promises. I attempted to connect peripherals and test various projects, only to be met with a complete lack of response. This not only undermines the purpose of the Raspberry Pi but also wastes valuable time and effort on troubleshooting and experimentation. Considering these issues, it is evident that the Raspberry Pi 4B I received falls far below the expected standard. As a consumer, I expected a reliable and functional device that would allow me to explore the endless possibilities offered by the Raspberry Pi ecosystem. Unfortunately, my experience has been marred by a faulty unit that offers no practical use. To resolve this matter, I will be contacting the seller to request a refund. I sincerely hope that they will rectify this situation promptly and provide a resolution to the issue. While I am disappointed with my initial experience, I remain optimistic that this is an isolated incident and that other users have had more positive experiences with the Raspberry Pi 4B. In conclusion, the Raspberry Pi 4B I purchased has been a major letdown. With no LEDs or functionality working, it has not lived up to its reputation as a versatile and powerful single-board computer. I am left with no choice but to seek a refund and hope for a better experience with a different unit in the future.
