Hackaday Prize Entry 2018

I’ve entered RAIN Mark II in the 2018 Hackaday Prize. This isn’t the first project I’ve entered in the Hackaday Prize (I think I’ve only missed one year) but this is the first time I have a project which appears to have some traction in the competition. At first I had very low expectations for […]

Arms & Legs

Technically, the Clusterboard fits inside the case I’ve been designing around, but it doesn’t fit inside the “endcaps” so it can’t be mounted directly to the steel of the case using the mounting holes on the board. To address this, I sketched-up some adapters to “relocate” the mount points somewhere more appropriate. Since I’m still […]

Front Panel Software

The front panel of RAIN-PSC serves three essential purposes: Show the status of each node Show the load on each node Look really cool The panel is actually eight individual control panels (one for each node in the cluster). Each panel consists of five LEDs and a toggle switch. The switch selects between two display […]

i2c Front Panel

Switching from individual full-size PINE64 boards to the Clusterboard necessitates a change to the electronics for RAIN-PSC’s front panel. The original plan was to use GPIO pins on each board to directly interface with the LED’s and switches on the panel, but the Clusterboard exposes far fewer pins for each compute module, so another approach […]

PINE64 Clusterboard

This week I learned that PINE64 (the company who makes the boards used in Mark II) released a new piece of hardware that could accelerate my work on RAIN PSC considerably. The PINE64 Cluster Board combines a gigabit Ethernet switch with seven SODIMM slots (along with the associated support components) into a single mini-itx sized […]
