Two-way Radio for a medium-size community

I have been thinking of building something like a two-way radio except that it should be more like a mobile phone network with the exception of call charges. it will be used in a small environment of about 100 people. I was wondering if anyone has ideas on how to build something like this.

JSON parse exception prevents editing or deleting of instructable

Try creating an instructable with the text below in the description. When you save it, a JSON parse error pops up. The same exception will pop up each time you go to edit the instructable, preventing you from reaching the edit page or ever deleting it. You apparently need to sanitize your input a bit more. SET count=0 setlocal ENABLEDELAYEDEXPANSION FOR /f %%a IN ('dir /b *.jpg') DO ( set /a xOffset = !count!*2 set /a xSize = 1098+!count!*6 set /a yOffset = !count!*1 set /a ySize = 732+!count!*4 "C:\Program Files\ImageMagick-6.7.3-Q16\convert.exe" %%a[!xSize!x!ySize!+!xOffset!x+!yOffset!] pan-%%a set /a count=count+1 ) The exact exception is: "There's been a problem updating your Instructable [object Object] parsererror SyntaxError: JSON.parse: bad escaped character"

I need help selecting a small camera.

I am gathering the materials for a project, and I need a small digital camera.The lens must not move, images must be downloadable via usb, batteries must be charged via the same usb.This camera is ideal, except it is way too expensive, and is a video camera (and it's from China, but that's another issue).This camera is ideal, except that the batteries are not charged via the USB, which makes my project much trickier (I'm going to be building the digital camera into another object).Can anybody recommend (or at least find online) a "happy medium" between the two?

The Book - a problem, and a solution

I just spent.. far too long going through the list of the entries for The Book.There are nearly 2000 entries. That's nearly a hundred pages to look through when dishing out your vote.There will inevitably be some people who lose out badly because their projects are so far down the list that people simply get tired before they get to the end and give up.I propose that the voting page for this exceptional contest be arranged an exceptional way - all on one page.A single list of smaller-than-usual thumbnails, with the title beside and a vote / unvote button or tick-box beside that.That way, all people have to do (all?!?) is scroll down a single page and click away.It would also be nice if that list could be re-arranged in order of votes / views / stars.
