Re: [WISPA] Things you might be interested in
Did you try RMS for your monitoring / control hardware? http://www.bndcom.com/rms/rms.htm They are $500 list, have 3 relays remote controllable - NO/and NC connections, so if you want a fail over to closed you can do it. There's 5 or 6 voltmeters, a 1/2 dozen TTL level contact closure sense items, low current draw - decent scripts. Haven't seen any for $200, but the guys at BND have said they are working on a new one - maybe lower cost. --- What do you mean by thermo-electric generator? Something that works from Geo-Thermal sources? Sterling has some interesting stuff. .:_) --- Great ideas. We've built lots of remote sites and frankly $800 / hour for a heli ride when things go south is crazy. We just don't do it. :-) Mark Koskenmaki wrote: I have found myself in need of some devices from time to time that I can't seem to buy at a reasonable price.

I'd like to know if anyone else is interested... 1. IP addressable, 10/100 ethernet based voltage / charge / temperature / monitoring and/or switching device. You could monitor batteries, solar panels, generator, start/stop things, etc. Cost: ~$200 2. IP addressable, 10/100 ethernet based thermo-electric generator, fueled by propane, either remotely controlled, or operating on a programmable basis - to operate as a backup power supply in conjunction with 12 or 24V battery based DC systems. Would provide battery monitoring, as well. Approximate cost: $2500 for a 75 watt 24V system. Could be made in 20, 50, 100, or larger wattage sizes - cost rises considerable with power output.This would serve as backup for a solar/wind or even for AC in conjunction with lead-acid batteries. 3. crash detect and reboot system. This would connect via 10/100M ethernet to a network, ping a programmable IP (in fact, several of them) and be able to power cycle dc or ac powered equipment. Programmable as to how many pings to miss, how long to power down, etc.Cost: ~$200. Each of these devices would be designed to operate on very minimal power and tolerate temperature extremes.

Haven't seen any for $200, but the guys at BND have said they are working on a new one - maybe lower cost. --- What do you mean by thermo-electric generator? Something that works from Geo-Thermal sources? As I said, run on propane. It generates DC power without any interference or ignition noise. It has no moving engine or generation parts. It directly converts heat to electric energy.These are available commercially now, but nobody makes them with an ethernet based monitor / controller, and they cost a fortune - many thousands of dollars, or else they are very small, and don't make enough power to be useful to a WISP. Sterling has some interesting stuff. .:_) Who / what? --- Great ideas. We've built lots of remote sites and frankly $800 / hour for a heli ride when things go south is crazy. We just don't do it. :-) Well, the idea is to build some stuff that really is capable of running for months without attention.Solar sites are often built for small power use, but generators that run on propane often don't like to start at 20 below, and you really can't tell what's going on if they don't seem to start.
