Raspberry Pi & Maker goodies
Curated range of best of breed products.
The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3 with 4 Raspberry Pi Zeros (NOT included). Configured to use USB Gadget mode, it is an ideal tool for teaching, testing or simulating small scale clusters.
As with most things there are many ways to configure the ClusterHAT. If you know what you're doing with Linux kernel Gadget mode and networking you can probably skip most of these.
Could this little HAT solve my issue? Want to run lots of sensors with multiple displays, but save images/data/video etc on a central drive? So, for instance, if cam2 had something interesting on, I could record it and it would transfer to the hub node??
It's a nice easy to use Cluster initiation using your Pi's. I like it that the way that the Pi's are positioned. It will power all the Zero's and with a internal network. In resume, no hassle with cables for power and network, really great.
supper idea love this thing alot!!!!!!!!!!
I thought I'd give this a bash as I'd been meaning to play with Pi Zeros in OTG mode for a while (thanks Andrew!). What this gives you is a nicely bundled HAT with space for four Pi Zeros. It features a USB hub that connects all four into one USB port on the host and the board also allows you to power up/down each Pi Zero individually. There's even a blue alert LED for when you want to alert someone. I (rashly) decided to figure it all out and configure it all for myself. Lawks a lordy, what fun! However that's exactly what it's there for: learning how to do clustering. The less foolhardy should probably download the images provided and use those instead.
I've written a detailed review of the ClusterHAT, including benchmarks of the networking and CPU performance. There is also a design for a compact acrylic case that you can download the plans for and laser-cut: http://climbers.net/sbc/clusterhat-review-raspberry-pi-zero/
very easy to install and setup. I am able to run Spark v1.5 cluster on it, but very slow 1/ beware that it only support LAN but not WIFI (difficult to create bridge) 2/ you can have 1 to 4 Pi0 installed on it 3/ found a problem on shutdown them, it just hang without disconnection. no idea why 4/ the HAT provides the power and USB connects them. I replaced the original USB with my own because it is longer
Works exactly as I'd hoped - the hardest part is getting hold of enough Pi Zeroes! I've used the supplied images to flash the SD cards and then installed Docker, everything so far 'just works'. The amazing part is being able to connect directly to any of the Zeroes from my laptop using a name such as p1..p4.local without having to mess with network settings etc - it's just magic! Thanks for a great product! :-)
