Question to the community:
For SP30 it's too late (we're too deep into the design) but for future miners, is LCD with Hashrate / Temperature / IP / other status desirable ?
If so, what data to display ?
Temp control is key when you have a more than 4 of these in a rackspace.
A simple temp LCD readout panel would only be an extra $10-$20.
The panel could light up Blue/Green when temps were in the normal range; Yellow/Orange when getting close to the limit; Red when over temp. And in the firmware you could throttle down the hashing until the unit was back to normal op. temp.
If an LCD panel was not an option, 3 simple led lights on the front face with the same color/temp arrangements would also suffice.
I have LCD temp panels on my units with a fan control knob and a freeze switch so I can control the temps with the fan and get the temps down from 50c down to 22c in about 45 seconds.
