And, Americans are already speaking out about how libraries are transforming their families’ lives through broadband. Connected Nation has captured some of these stories in a video called “Connecting America Through Broadband at the Library.” In addition, Connected Nation’s survey research--which was recently filed in a policy brief with the Federal Communications Commission—further validates the important role libraries play as a community technology hub.

Watch Video “Connecting America Through Broadband at the Library.” http://www.youtube.com/watch?v=iz_NdjVxc1Y Along with this anecdotal evidence, Connected Nation conducted surveys across the states of Tennessee and Ohio to better understand the role of libraries in the broadband age. The report has been filed with the FCC, encouraging the commission to consider the important role community anchor institutions—specifically libraries—play in the national broadband plan. Key findings of this survey research include: • Significant percentages of those who normally don't subscribe to broadband – specifically single parents, minorities and low-income residents – are relying on the local library as their sole or primary Internet resource: 25 percent of single parents, 25 percent of minorities, 18 percent of low income residents, and 11 percent of people with disabilities depend on libraries for Internet connections. • More than one-half of library Internet users (51 percent) have children at home, suggesting that a significant portion of library Internet users are children. Of this group, 42 percent do not have a broadband connected computer at home. • Library Internet users are significantly more likely than other Internet users (those who connect at home or elsewhere) to use a number of online applications related to workforce development and education, civic engagement and healthcare. • Nearly half of library Internet users (46 percent) search for jobs online, compared to 29 percent of other Internet users. • Library Internet users are significantly more likely than other Internet users to communicate online with local government officials (25 percent compared to 14 percent.) • 28 percent of library Internet users communicate online with healthcare professionals, compared to 16 percent of other Internet users.

Re: [WISPA] powering finicky mikrotiks on 24v solar - $2.75 solution
I came up with a solution for this problem for now. I use West Mountain Radio Rigrunners ( http://www.powerwerx.com/west-mountain-radio/rigrunner-4005.html ) to distribute my voltage and protect my devices on solar installs. Makes for a nice clean, easy-to maintain and troubleshoot install. They go up to 38 volt, even though they don't say that in the descriptions. I bought some radio shack 276-1143 diodes - 200V 3 amp ( http://www.radioshack.com/product/index.jsp?productId=2062578 ). I crimped a red Anderson powerpole connector ( http://www.powerwerx.com/anderson-powerpoles/powerpole-sets/15-amp-red-black-anderson-powerpole-sets.html ) on each end of the diode after shortening the leads a little bit. Then I put that inline between my Rigrunner positive terminal and the cable that feeds my Mikrotik device. I label the end that goes to the Rigrunner - the side of the diode without the white stripe - with yellow tape so I don't end up putting it in backwards later. I use one for each device. Drops the voltage around .6 - .8 volts, enough to give me the margin I need on my radios. On routerboards that are very close by (no voltage drop due to ethernet cable length) I put two of these devices in line to drop it 1.2v. I'm cleaning out the local radioshacks and building a bunch of these for future use. Randy -- Randy Cosby Vice President InfoWest, Inc 435-674-0165 x 2010 http://www.infowest.com/ WISPA Wants You!

Re: [WISPA] powering finicky mikrotiks on 24v solar - $2.75 solution
Fine business using the diodes to drop the voltage. Many silicon diodes will show a higher voltage drop as the current increases. Depending on the circuit you were measuring, one with higher current would show a larger drop. That is an innovative use of diode voltage drop.

Re: [WISPA] powering finicky mikrotiks on 24v solar - $2.75 solution
Be careful using those diodes at sites where you're colocated with a high powered transmitter. The diodes can do some weird stuff (rectification, mixing) and could become a hidden source of interference/noise.

Re: [WISPA] Suggestions - paint overspray on solar panels
Water companies usually use a very special paint (very fluid with odd chemical comp). You should first contact their contractor and find out what the recommended solvent for their paint is. Then call the panel manufacturers to ensure that the solvent won't damage their panels. Might save you some $ and a climb or two.
