We recently converted an internal dashboard for the Helium blockchain to a public tool and the reception/usefulness has been awesome. (For anyone interested -> http://dashboard.helium.com)
Mark from Helium here. Fair point on not publishing designs. You're not the first to bring this up and we have plans to make this a non-issue in the future. Shoot me a note - [email protected] - if you're up for talking further. Any other thoughts / critiques would be most-appreciated.
If you're looking for a sensor platform that will let you quickly deploy a sensor that will run for a few years on a pair of AAs, check out what we're putting together at Helium [1]. We just rolled out the presale of our Helium Atom Development Board [2] which uses the Atom - our drop in connectivity and compute module - as the basis for a sensor development board that is actually fit for production. The OS that runs on the module - cleverly named Helium OS [3] - is the basis for our edge programmability and abstracts the annoying, hard things like battery/power management, wireless, and security. Also OTA upgrades are built in. :)
Very cool. I had heard rumors that Tim was working on this. He did some great work with the NoSQL Tapes [0] a while back. I'm hoping these are of a similar caliber.
Congrats to the team. Well-deserved.
