Raspberry Pi cluster

Frankly, I think it is not necessary. Preparing a post of a Pi Cluster for the Pi 4 roadtest but really it is not necessary in my opinion.

Don't these kind of products already exist? I thought there was a PiFace or similar board for exactly this purpose.

If anyone had such a need, there's an alternative approach: take a 8-port switch with PoE, and feed it directly to 4 or 8 Pi's. No non-standard cables needed, and no need for a manual switch, power can be controlled independently remotely.

By the way, the product logo looks like a supermarket logo, I know it's supposed to look like a four-leaf clover, but to certain regions it will always remind them of a supermarket.

I took a look through the website and found no useful information other than boiler plate material for a startup. The galley section of the site doesn't appear to be working at all.

What is the price point for such a product?

What is the price point for such a product?

It's $100 for the kickstarter reward, and normal price of $150, and the kickstarter has exceeded it's target. Impressed people have a use for it!

It's like a 5-port switch with DIL headers so that can only be used with the Pi, and 4 small DC-DC converters basically.

A  5-port switch costs $7 from Aliexpress like the one in the photo below.. and that is more flexible because it has standard RJ45 and so is not restricted to only working with Pi's) - and doesn't rely on using all the 40-way connections on the Pi as vertical supports either.

I 100% agree with you, Shabaz!

And also consider that there is the same effort to make and configure the Pi in a cluster array as well. The example below is almost the same thing you mentioned but should add about 1.5 Euro of printing filament.

Or, just in case you want something more professional, there is still the most tested and well supported (IMHO) Bitscope Blade Quattro Pi that costs just 1/3 of this stuff. With more options! Frankly this seems a nonsense.

Hi Enrico,

That's it, Bitscope Blade, I thought there was something like this but I couldn't remember the name!

The first one you've shown (the 3D printed one) looks really great, and the sideways fan is a nice touch too!

Maybe this one...

Would be a super cluster.

Thank you Shabaz,

the side fan comes from an ATX power supply and it works by a couple of months. I plan to finish the video today and publish it in the Road Test Pi 4 section. I had to delay as it is chapter 6 of the book .

And it is relatively cheap Clem, as well as stackable. The problem s the cost to fir the stuff in it

There are much better alternatives: cheaper too:
