I have been working on this project for a while: https://www.machinon.com/ which is an expansion board on exteriors for the Raspberry Pi. Originally was designed for Smart Home Automation and the idea was that anyone could through there any software package they wanted, since the interface with the board is using an open protocol known as MySensors.
The good bit is that all the I/O handling, interrupts, counters... are done at hardware level so the RPI does not need to know about it, just ask (push &/or poll) metrics.
Recently someone brought to my attention Node-red so I did a quick test. However my expertise is mostly on embedded devices (the board) and not so much high level coding.
My questions (and I hope this is ok) are:
1.- Is people interested on this type of hardware? My intention is to manage a small (Indiegogo / Kickstarter) group buy and pass on at cost, you can see where I am right now negotiating this: https://www.machinon.com/blog/looking-for-small-batch-manufacturing
2.- of the (hopefully) people interested on this type of hardware, is there anyone interested on working with me to develop a connector for it on Node-red?
